Hi Ben. Cherish every moment you can have with your mum.

I would imagine the atmospheric pressure is just what it says, the pressure of the atmosphere on that day. If you had a depression nearby, it could easily be 991 and would only change as the weather does. Well done for sorting it for your mum.

Your mum seems such a sweet lil lass, I always wash out DPF’s unless it’s damaged there’s no point buying new. Yer a good lad helping Mum out- Hello Tasty Classics Mum.

How lovely to get your ma in a show. Good on you both. Enjoyed this little deviation from the TC norm 😎👍🏻

You're mum is so sweet and to think she could have been ripped off is disgusting. Well done for sorting it out and that Renault is very pretty, I myself have had Renaults and I've loved them ( 2 Lagunas/Renault 11/Scenic and megane coupe). You are always guaranteed a comfy seat and electrical gremlins with these cars.👍

And this is why I always use the same garage for servicing and mot. They are fair and explain why they need to fail or advise what needs to be done. And never replace anything that doesn't need to be replaced.

We had an old Brown Renault 5 on our farm and it lived for years and years and would not die. We put livestock in it, lambs and calf’s mainly. Hay bales, animal feed, vets, herdsman and so on. In the end we drove it off a ledge into an empty gravel pit, 30ft drop. When we got to it the engine was still running and it still drove (sort of). We left it in the pit and it has now lived in a 30ft watery grave for 35 years. Hell of a car and it still brings a smile to my face when I think of the scrapes we got into in it.

What a delightful episode. Your mum is a very charming lady.

What a delight. Fun , adventure, diy fixes and great entertainment. Well done Ben. I look forward to finding you.

Hello - love your vids. I had similar issue with my wifes Mercedes C250cdi. Limp mode, check engine light on. Although I am pretty handy with the spanners, all my experience is petrol cars and I have always heard DPF issues are a nightmare so I was pretty annoyed to see when I plugged in my little OBD reader and got DPF codes. If this happens to others stop right there. Don't go any further until you plug in a decent scanner. Luckily I have an Autel 906pro. This revealed in fact that the code the little OBD reader gave me was correct BUT in fact it was two codes with the same 4 digit number but a 5th number giving more specific information. This pointed to a pressure sensor. On the Merc it is a differential pressure sensor so it has 1 electrical connector but two pipe unions - pre and post DPF to compare the pressure and establish when to re-gen. This was knackered. Changed that and like you was miffed that it was still in limp mode despite a few Italian tune-up's down the local Autovia. Then I came across "Adaptations" on the Autel. Went through that procedure - it learns the new values - and bobs your uncle, sorted. The good thing is that the 906Pro is accessible to most people - Snap-On brilliant but a huge amount of money. For a grand you can get a used 906 or 1500 new one. Its saved me thousands over the years. Greetings from Spain!

DPF probably didn't need to be removed from the car. All it needed was to fix the underlying fault that was causing the car to not regen the DPF. Which in this case was a replacement sensor plus telling the car the DPF plus sensors had been replaced / re-initialising them. And then maybe a clean with Launch DPF cleaning fluid with the DPF in the car. Oreilley's youtube channel has loads of useful DPF videos. It seems that there are loads of mechanics that are hopeless with DPF's. But they are actually quite straight-forward, once you understand how they are part of a system in the car.

Your mum is absolutely lovely I warmed to her the second I heard her soft spoken voice. She’s done a good job with you that’s for sure. Think she needs to be on the channel more often. I’ve had 7 Renaults and every single one bar my 25 failed In life miserably 😂😂

God bless you and your mum. Enjoy every moment you can with her.

I had Leon a few years back with a DPF, the guy at the garage told me about the potential DPF issues and his advice was 'thrash' the car in low gear at least once a week as it prevents potential clogging issues.

Your mum has such a calm, soothing voice. She should be the satnav voice - it would cure road rage!

Inbuilt obsolescence by the manufacturer. Good to see the resolution ☺️.

Simple women with simple needs A rare breed

The pressure line from the dpf to the differential pressure sensor is the go to source of problems with a clogged dpf. The dpf itself may not be blocked at all but because the pressure line is blocked the ecu thinks the dpf is blocked. Of course the dpf may be clogged, but with a correctly reading dpf diff sensor the ecu may then allow a regen. You can clean dpf's yourself, just blow it out with a pressure washer and dpf cleaner. Little tip for moderately driven modern turbo diesels, use a fuel additive regularly and every 6k miles or so, use a high intensity diesel cleaner. I use Mannol ester fuel treatment on every other tank of fuel, it's 1ML per ltr of fuel, so very cost effective, and JLM extreme clean for the every 6k mile treatment, that is quite expensive at almost £40 for a ltr can, but worth it to keep carbon at bay. Also, it would be worth checking and cleaning the egr valve, it's very likely that will be well clogged to.

Your Mum is lovely, I thought she would be Welsh !!

I love your mannerisms around your lovely Mum, you don't say anything against her, but you give the camera that look whenever she says something doddery. 😂

I feel like this is classic car guy & mother stuff. But we still love them and love to take care of them and their car!

Oh Ben, we love our mums. Mine's been gone many years now, but still the glue and gaffer tape of our family. DPF's though bum pain indeed. Had one on a 1.4 HDI peugeot that was being a helmet. It was so slow, it couldn't pull the skin off a rice pudding. Dealt with on a downhill stretch of motorway from 5th to 3rd several times. Gearbox fcked but DPF lived another day 👍

Can't fault the choice of car - I've got a 2005 Grand Scenic that I bought as a very cheap runabout in 2018, before the electric handbrake failed, the MoT expired and I left it standing on my driveway. It was so nice I wanted to put it back on the road, which I did in 2020. Since then, in total I've spent £2,086 on parts (repairs, servicing and cosmetic improvements), and done all the work myself. I've thoroughly enjoyed doing it and learned quite a bit about working on modern-ish cars in the process.

Thank goodness I drive a 300D Mercedes diesel 1978. Only electrical components on the engine are the glow plugs and starter motor. If warm enough, don’t even need the glow plugs. 😂

Hi, great vid, lovely to be able help your mom, great to see her on with you, Mark

Well done Ben, family must stick together,it worked out well. Very enjoyable

Hi Ben,her indoors has the petrol grand scenic that I spend a lot of time under. To clear some fault codes I disconnect the battery, reconnect,reset the damn radio code then just drive normally for a couple of days and let the brain reset itself. I find this better than giving my hard earned cash to the local Renault dealer, the other thing is most code readers don't work on her car.

Your mum is a legend, our family always had Renaults, now I have a Mégane RS 265, Clio 172, and a Mégane r26. They may not be the most reliable but love them.

Nice to see you helping out your mom. Top bloke! 👍🏻💪🏼

My mates dacia duster had a blocked dpf, he took it off to get it cleaned but it was too blocked. I cut a flap in the top of the chamber and drilled /chiseled it out, it was full of black gunge. The steel was too thin to weld so I repaired it with a piece of stainless steel plate gun gum and tek screws, it been fine since, goes like the clappers and has passed a couple of MOTs.

Nice to see another vid. 🙂 BTW "Atmospheric Sensor" would be measuring the atmospheric pressure (ie, the outdoors) not the exhaust, surely? Interesting to hear the calibration process that the mechanic had to go through. Modern cars eh. 😅

I bought a Renault 9 once for £3000..... once was enough! 6 clutch cables, 2 clutch pedals, 4 speedo cables, 1 new door lock and a cv joint later, I sold it for £50! Biggest load of ballsack I ever bought!

had my renault done by O,Rileys Autos, he has a chanel same name, he videos the whole process and explains what to do and puts it on utube and no need to remove the dpf off the car, well worth a look 😁

You have a lovely mum there, Ben and I'm glad you fixed it for her. Back in my day I had a girlfriend with a T reg Renault 5TL and it went like stink. Embarrassingly enough, I had a job keeping up with her in a Escort RS2000. I think my favourite looking Renault was the Renault 17TL/TS.

Great video and great to help mum😀♥️👏

What a lovely son.

Nice one Ben I had a s scenic drive well but if it was not leaking the windows getting stuck for ever buying switches for it then I had a oil leak and cud not get a O ring to fit like your problem no other part wud fit so had to bite the bullet and buy the part for 200 note and then to top it off a week later after fixing it someone hit me head on and written it off .i think it was a blessing in disguise Have a Top week dude 🙂🔧✌️

Renault are evil when it comes to repairs, they have always tried their hardest to make home repairs as awkward as possible. My first job was in a motor factors and Renault's and their oval plate numbers were a nightmare, two Renault 5's built on the same day of the same trim could have lots of differences such as one might have Bendix calipers but the other might have girling and one might have a Bosch distributor while the other might have a Lucas style. Of course I still bought a 21 Turbo years later which was a fantastic car apart from it's very militant french electrics.

All I got from this was that I miss my Mother, nearly 14 years gone now.

Another way round it would have been to get the car Terracleaned. Probably cost about the same but you don’t have to remove anything. Had my Jag XF 2.7 diesel done and the difference was amazing. Even my wife noticed !😊

I kept getting a stuck in regen problem in my Astra H. So Sunday morning I took it for a blast down the M23 to cook it up. Problem sorted. Seven days later a speeding ticket! Bollox.

Mum's cool, dire car choice though 😂

Aww Ben's mum is lovely , well done Ben !

Ben although I watch all your videos anyway because they're fab, I actually prefer you doing quirky fixes like this that shows how you got around otherwise prohibitively expensive standard solutions. Magic worked again.🎩

Your mums a lovely lady ben cherish her always❤❤❤

Well done Ben, got to look after your Mum. Let’s see 20k subs on your next video!

To be fair the 1.5dci engine is one of the better ones out there. My wife is on her third renault starting with a new grand scenic in 2011 . It was faultless in every way. Traded it in 2018 for the new grand scenic . Dissapointing car compared to the older model . She traded that in 2021 for a megane rs estate plug in hybrid . Absolutely fantasti. Machine . Its quick and does between 80 to 90 mpg. . I drive a 2012 vw touraeg which ive had for 6 years . Its heading gor 250000 milles on the clock and i love it. I also have a few cassic toyotas in the shed . Dorfy for the long msg but im in bed with covid at the moment. Really enjoy your content.

You know the video isn’t important here. It was fsking fab to see you looking after your mum so well and as much as anything the wonderful rapport between you both. Treasure those relationships! Fair made my day young man! :)

I really enjoyed this episode of TC. You're Mum is gorgeous, and I hope you fixed her reg plate light too. :) How dare Renault try to rip her off like that! She lucky to have you watching her back, that's for sure.

Great real world diagnostic and a happy Mum what more could anyone want!

Loved this Ben, this is the kind of knowledge I like to have in my back pocket. Garages will try their best to make as much money out of the general public and especially women. I fixed my car myself over the weekend and saved upwards of £300 doing the job myself. Being as my car is a 2011 ML350 I felt very accomplished!!!!

Hi Ben. I have had my renault grand scenic. 1.5 for 10 years 258000 miles. Still going strong. Have hardly paid anything for repairs. Love mine.

I had a few Renaults. My last one got written off by a cement lorry and that did me a massive favour! It had a misfire problem at cold and three separate garages couldn’t fix it (incl. main dealer, independent Ren specialist).

Your mum is a sweetheart

Waiit till your mum get into a Honda, your mum is so sweet.

Super work Ben.. well done what you need to do is take it out once a week to give it a blast to keep the dpf empty. I dont know in renaults but in peugeot and citroen theres a dpf additive fluid you put in a tank which is added to the fuel to help burn off the soot build up when out on a motorway run etc...

Hoorah! You won the day. Excellent result for both you and your mum. 🏆😊

That's what its about saving money, my dad took his defender over to where he normally takes it, and they wanted to charge him 1200 quid to do a list of jobs, one was 200 quid to toss a bottle of injector cleaner through it, and a £1000 for a steering box, We were like where you getting those wages from?? The steering box only came to about 400 quid, he was putting £400 on top that, then £200 for labour. We took it else where and they moted it, They said nothing wrong with the emission smoke side of it at all, and the steering box was an advisory. I got in touch with a company who revamps steering boxes, and got his done for £200 quid. From the £1200 that the garage wanted to charge my dad, He managed to do the job for £400, and that was adding new pipes and PAS pump, So well under what the garage was quoting and wouldn't have done. Also my dad threw £300 at it for a new rad and fancy pipes. So it was all in for £800, £100 for the two MOTs.

Brilliant vid Ben 👏

Your Mom is a sweetheart sadly mine is gone. Thanks for the sticker you sent me!

What sweet lady your mum is and you are a good son doing all that rather that getting ripped off big time . Cheers 👍

The spanner light on your mum Renault Scenic is the service light you can clear it with a dianostics machine or genrally the buttons on the steering wheel do it as well love the content keep it coming ❤

You're a hero , well done .

You have a lovely mum. Your such a great son helping her to motor on !!!! 🙂

Looks like that the exhaust back pressure hose is blocked(pressure upstream of turbine). It’s a thin metal tube that is connects to the exhaust manifold which then connects to a sensor to read the back pressure of the exhaust gases. It monitors the pressure before the diesel particulate filter to identify the difference in pressure caused by a build up of soot in the DPF filter. It’s also does another stuff which involves improving the response time of the turbocharger. You also had codes for low boots pressure this might be the reason why. This is a different sensor from the DPF pressure sensor. They work together to Tell the ECU with do to a DPF regeneration. Going off the live data results the pressure should match the engine rpms when you rev the engine. If this is not sorted then your DPF will block up again. Your DPF can be cleaned with out taking it off. It will save your a lot of time. Have a look at the Launch Uk DPF cleaning website.

Nice one. This stuff is always good to know in case of future problems.

If a filter is shown to be 100% blocked you are prompted to replace the filter on it. So press the button that says you have replaced the filter. Then clear adaptions which adjust the system as it ages. Then clear codes and a big run to clear the system. The problem would be if you said new filter fitted and reset everything and the filter was still blocked the back pressure and heat could damage things. Clean filter, advice new filter fitted, clear adaptions, give it a run. Watching live data is a good thing shows sensors are working. Differential pressure sensor is a key component, it and it’s pipes need to be clear and operational. Launch UK do some juice you can put in the diesel to help town driving that might help your mum going forward!

One of my favourite cars of the past was my 1972 red Renault 12. So smooth to drive and reliable as well.

Quality content and great to see you mix it up. Pleased mum is up and going mate.

Fantastic video. Pleased you got sorted and saved money 👍

Miss you both!!! HUGE LOVE!!! xxx

It measures the pressure difference between the before and after DPF - the higher the difference the more clogged- this is the problem with DPF, most times they clog because of a fault - often those pipes split from heat as you say. Sometimes the code will clear after 5 drive cycles. but I've seen where you can only reset as the last part of a regen with clip

Revving the bollocks off a 2L turbo diesel won't have much effect on the atmosphreic pressure reading, cos that's the air all around us being squished by the forces of gravity pulling it down against the earth, so the car's sensors take that reading, plus the resdings from the other pressure sensors for the turbo gubbins, it does mathemagics and stuff to squirt the right volume of fuel to air ratios, and then allegedly makes the car go, also 2L diesels aren't good for pottering about, they're motorway mile-munchers, gotta get them all hot and bothered so they don't make their own supply of coal... :P

Great your mum loves her car good for you to look after her. Car after all we only have one mum

O’Rileys Auto uses some stainless wire on a drill to clean out the pipe and once he has broken through he uses the Launch UK juice diluted fifty percent as recommended and using a spray gun blows into the particulate filter the recommended amount. It dissolves the soot. The differential pressure sensor measures the blockage across the filter. Watch O’Rileys Autos he is in the know.

😂 Your mum is essentially the same as every other British Mum ever when describing why she likes her car - great vid! 👍

The reason this happens to so many DPF systems is that the vehicle needs to be driven on the highway regularly. Trucks fitted with a DPF come with a manual reset(clearing mode) in case you have to idle lots, or drive in traffic(more clogging). This is a domestic diesel problem as this feature is not implemented on most smaller diesels with a DPF. If your mum wants to not have this problem again she needs to drive on the motorway more or purchase a something that doesn't have a DPF. Even if she had purchased a brand new DPF it would have happened again eventually.

Diesel owners take note you have to get those rpm's up regularly or it will cost you. Great vid. Btw considering your mum driving style you could delete the DPF.

Love the thumbnail Nicely done That GOT attire fits ur personality

I am the proud owner of a master a megane and a twingo and they are all magnificent.

Your a good lad for your mam.

Brilliance! Enjoyed the principle of this! But elephant in the room… how is mum younger than you? 🤣

Great stuff , I like how your video and effort shows the people as to how they themselves are so easily extorted out of their cash. I bet the dealerships wouldn't advise a driver to have the unit pressure blown clean. No their Job is extortion much better off with the Classics that what we know to be real cars for real motoring . Not a half ton of plastic and 50 uneccessary sensors BTW when the Driver themselves had a pop at getting the vehicle ready for its MOT with the Haynes Manuals..

Great result but still a lot of wedge 🤦‍♂️ i stepped away from diesel after my mk4 Golf pd130 left the fleet! Your mums car looked great underneath for 13 years old 👍🙂

Well done mother and son

Glad it’s all sorted you’ll need to take your mums car out maybe now and again to give it a good blow out.

Great stuff helping your mum out👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏

Other option is to remove the cat/dpf nock all the insides out put it back on the car and have it mapped out at the cost of around £150, this also reduces the back pressure the turbo is facing and makes the car more drivable. Of course it's illegal to do it but speeding is to and everyone does that.

Well done always look after your mum 👏

Its weird how you love what your bought uo with im a ford lover mate of mine hus family had audis so he loves them.

I have a transit custom that I bought brand new. 18 months later it needed a new engine under warranty. It’s done 60k and has been main dealer serviced every year. A month or so ago I got a DPF fault. Crazy money for a new one. I bought some DPF cleaner off Amazon. Ran that along with some injection cleaner. Cleared it. Fingers crossed.

The injection warning comes on for the glow plugs normally. I hate anything French and refuse to work on them. Also you can get dof ckean fluid you fill it through the temp sensor hole and leave it a while then rev her up, this has saved every dpf I've used it on. Also if you fancy a drive with a trailer to the south coast I have the original rover promo 75 estate been sat at my yard for years you can have for free if you try rescue it. My health means its been left along with some other gems.

My parents had Renaults when I was young. Both Renault 17s, first one a TL and the 2nd a Gordini which was advertised with Bosch fuel injectors and Ziebart rustproofing which obviously didn’t work as you don’t see any on the road anymore 😂

What a good son.

Hi, great upload! What happened with manufacturing 70ties onwards, cars are the early adopters, is that products are made to generate revenue, to last but with considerable cost. Front springs will snap roughly every 4 years, each MOT has to bring in between 4 to 600 pounds no matter what. Parts prices increase 25 to 100% each handling step, excl import duties.... I do classic & prewar, the rest, exceptions excluded, are just cannon fodder to be remelted. I will not start on EVs..... Great channel!

The cars now not detecting a problem you havnt re set and re calibrated the new sensor youve put on go in to function test on your scanner and see if theres a re calibration for dpf and differential pressure sensor then cycle ignition back on and re clear codes again. If else fails spoofing a regen upon reseting the diferential pressure sensor and dpf values back to zero can also sometomes do the trick, find a mechanic with a snap on scanner like an ethos edge or a triton if yours cant support the function. Make sure its up to temprature and adhere to the regen guidlines

I have a Renault grand scenic 1.6 DCI 2012 it had been maintained prior to purchasing ( smart vehicle app) so I only need to keep up with the maintenance. It's an amazing car and everything works. It handles well, I had Michelin tyres all round and with the help of the on board computer , it handles well. It's comfortable and well equipped. I believe I can do at least what it says on the mpg figures. God bless you and keep you in Jesus Mighty Holy Name

Great video, just make sure your mum lets you know asap if any warning lights appear.

Loved it weve all had a lovely mother , well hopefully, an l used to sort my mams vauxhal nova,s out for her so totally loved this little video, love life family 😊😊 thats it , good on you Ben salt of the earth 🌎 😊

That's a grim way combining the dpf and cat so you can't smash it out and remap it to run without it,well done Renault!
