Hi Dean. I have a 2 Audi Allroads with same suspension setup. 55 plate(C5) and 60 plate(C6). These have self levelling suspension so if one corner drops the car compensates by dropping the others. Lift the car to maximum height and put it into jacking mode via the MMI. This will disable self levelling and if you have a leaking airbag, only the faulty corner should drop. As posted earlier, it would also be advisable to replace the air compressor relay with an upgraded version. Good luck👍

Dean, this is why you have 87k subscribers, because they want to see cars like these being bought and repaired. It's why I look forward to every video you put out. I'm sure it will be worth the cost and effort to get this car back on song.

I had this exact same fault with my Q7. Turned out I had a slight leak in one of my front airbags which made the compressor overwork blowing the fuse. I had the fuse replaced and ran it but ended up frying the compressor a few weeks later. Had 2 new front bags and a compressor fitted,problem solved. I have a brand new air block for the back of the compressor sat in my garage that wasn’t fitted. If you need it you can have it for the price of postage and a couple of pints😁

This car is my daily driver. I too had to change the compressor: I first cheaped out on the refurb kits (to no avail), followed by the 200 quid compressor (repackaged China) from a UK ebay seller, which only lasted me 4 months. I then bought the original OEM WABCO for around 400 euro from Germany. That one is working great, fingers crossed:). I also changed the valve block (just because I wanted to) and two strut valves. Luckily, my bags are not leaking, but I have a guy who can replace the rubber sleeves for 80 euro a pop (no need to buy a new strut). It is also important to change the plastic height sensor linkages because they seize over time; one UK ebay seller sells adjustable linkages made out of metal. Mine were super seized. And, don't forget to change the compressor relay; it comes with the new compressor.

TPI for suspension leaks. The orange, purple air lines rub on the chassis and get pin hole leaks. TPI give a part number for new air lines and connection, then you have to re-route the lines away from the chassis.

Thanks Dean, loved this video I have a 2007 Q7 so no doubt will have suspension issues. I have changed the relay under the dash as a precaution but wasn’t aware of the 2nd by the battery. Looking forward to part 2

Transformation was very satisfying 😁 breaks my heart to see how badly some people treat their cars 😩 Good job Dean, keep on working thru the issues. Love these videos!

In the meantime the guy who sold you the car is kicking himself screaming "A flipping fuse"

I've got a 4.2 one of these and believe me that pump has had it, you cant hear mine even when you know it's running. There are also holding valves at the top of each air bag the maintain the level and they deteriorate over time.

youve had a right result Dean..for sure this is a keeper,,the outside is cosmetic no problem for a man of your means,,have a good weekend Dean looking forward to the finish on this one,👌👌👍

I've always been in love with these vag big suvs, q7, touareg, cayenne they are so cheap.. But the bills that come with it usually it's scary

I've been working at a body shop for a bit now and extra tips I learned was if you're painting the door, it's better to take off the mirror and belt molding (the trim at the bottom of the window) for a better paint job in the end. The mirror can get in the way, and if you're unlucky, the clear coat could stick in that gap between the door and the belt molding.

What a bargain. I have a 2012 Q7 had it 4 years and its been a brilliant car. I also have the air suspension and its been good as gold. One thing i will say is the compressor on yours is really loud compared to mine, which i dont really hear atall. Give that thing a nice remap! It makes a world of difference and is actually rapid at just over 300bhp and 630 nm of torque

Really impressed with your whole skills, and tenacity. I do not like complicated modern cars. Morris Marina, built out of stainless steel would be my number one choice, but I am nearly 70 yrs. Peace be unto you.

Nice for a grand, always fancied one of these but got scared off by the hype of how complicated they are, so looking forward to this series 👍

What an absolute bargain for £1k, was expecting it to have very high mileage. But only 68k is very low. Can't wait for the next video dean 👌👍

Hi Dean, a fuse never blows for no reason. The compressor has an NTC sensor (overheat) which inhibits relay coil to shut of power. If the relay is welded shut (on) the NTC ecu control does not work, it then runs the pump forever, vents the overpressure air and burns the compressor out. It will be caused ultimately by a combination of leaks adding to increased demand on pump duty. Recently I found leaks around the joints on the front strut top aluminium housings (porus) that was the leaks and the demand. Clue was the car (cayenne-same as q7) was down on its nose in the morning. For what its worth, monitor pressure vs temp vs demand call from the ecu to determine a lazy compressor - it will be at this age, so a decent replacement around 350 quid, easy to fit plus new relay. You need however to fix the leaks. Get so soapy water in a spray bottle, with system pressurised, spray every joint, pipes, tops of air springs etc. Leaks will blow bubbles Dean - cheap and easy. Then fix the leaks...

The tank of fuel is almost more than you paid for the car.

The car starts and drives and you bought it for 1000,man this is a win theres no way you can make a loss on this.

Really appreciate your diagnostics and description of the problems and how you went about fixing it.

Just found you on the Tubes, great video and great production. Thank you!

As everyone said pump is unusually loud and poss pinholes in pipes/bags valves. Good luck love the cheap flip vids also. Great variety on the channel. Excellent work as usual dean. Was looking for a 4.2 petrol v8 FSI Q7 but are rare as hens teeth lately. You did super well for a grand but it’s poverty spec no Xenons no colour mfd or colour mmi to name a few lacking options or likes of Xenons, pan roof etc etc. at least it’s an sline that’s a biggie!

Look, each bag has 2 o rings. Get the o Rings, the inner bumpstop and some silicone grease. Get it apart and just replace it. You might only need that work done. I think you need the upper air valve new too.

New to the Chanel but I like you’re no nonsense approach and will continue watching

Great car. I want a 2010-ish Q7, but without air suspension - that seems to be one of the biggest problems with this model.

I reckon your Audi is a score. I had Air Suspension problems on my Mercedes and the stealership wanted over $10k when I first took it to them. I fixed it all myself using aftermarket parts for a few hundred dollars! Cheers Drew

Great buy looks nice I know some attention brings it back to life I own a Q7 2009 currently at the shop as it has a leak on the valve head cover ordered a aluminum one as I will keep it running. Has 185,000 miles and still drives Amazing.

I had a 2007 3.0 diesel. That orange fuse would blow maybe twice a year. You can just squeeze your hand in under seat to replace it (no need to undo any bolts) Moved it on eventually when the boot motor and infotainment started to play up. It was nice when newish, but those electric gremlins sure do come thick and fast as it ages.

Looking forward to the next part, believe you have great value and a good car in the long run! 👍

Remove the Vindis sticker off the back, will improve the value :D Always wound me up how they continued to put those on long after most dealers gave up!

It's a nice car and given your abilities and willingness to use ebay/pattern parts, it's an easy choice, fix it and ditch the pickup! Good luck and keep posting the great videos.

I would buy this car in a heartbeat, no questions asked. It is a good buy in my opinion. The interior looks great ! I wish I could find a car like this for a 1000 euro. Good luck on fixing the air suspension.

Hi Dean, I really enjoy your video's and it also served as learnings in one or another way. What happed to the Q7 is there another Video number 3 on it ?

Great vid Dean, can't wait for part two!

I was hoping that you wasn't going to wash it yet Dean, I'd love to clean something like that. The before and after shots would be awesome 👌🏼

Dean, a common fault on q7 is connection to air bag from air pipe. With time it corrodes and leaks air. One of the solutions is to take a copper washer and replace it in that connection.

Wife had the exact same issue with hers - thankfully fixed under warranty. Further cemented my love of older uncomplicated cars but hey... the Audi's nice while it works lol

Low mileage on the odometer, could be a cheap and comfy towing bus 💪🏻

Love it when these deals come along!

I had the exact same symptoms, suspension bottomed out and lights on the dash. It was just the massive 40A fuse. No independents wanted to know because they couldn't diagnose the air system. A month wait for Audi to look at it forced me to Google, and found an obscure american website with one reference to that fuse. Cost me a couple of quid to fix and had years of happy motoring aftwerwards. Felt like I'd won the world cup after looking at the potential costs.

Great video, what a result getting it useable with just a fuse!

Audi drive beautifully. However it can be a nightmare under the hood. Changing the timing chain can be a monster job. On a older one that has yet to show any problems, I would change the timing chain tensioner and cross my fingers. You can always drop the oil pan to see if chunks of the timing chain guides are there and of course look for any glitter or chunks.

New to your channel and very impressed on first visit Hope you get a good fix without to much expense

Hi Dean. Not a car for me. But saying that. I think your on the right track with a repair. Also plenty of suggestion in other comments, on where to go next. See you in the next one. 👍👍

When the pump is that noisy it basically Knackered, the new one will be a lot quieter, that said you likely have a leak in one of the air shocks, you need to replace or you will wear out the new pump in short order. I had this issue on an X5, ended up whipping out the bags and put in springs.

Just stumbled on to your site. Great video, thanks.

Make sure you drain the plug because water will get in the ecu.. a blow it. It happened to me 🤦‍♂️👍

Was in a scrappers yesterday plenty of recent-ish Audi's - no Q models oddly - appalled to see doors left wide open to the weather, presumably by customers, and leather interiors getting moldy. I must have looked obsessive, I closed over 20 doors. Quite a few had Bose sound systems in them complete with door cards, cheap upgrade if you like your music - simple plug n play surely?

Typical air suspension fault is due to oxidation build up on the connectors .. had a similar fault on a w205 c class , merc as usual recommended by replacing the compressor without checking.. long story short cleaned out the oxidation build up and sealing jt better than factory.. never had a problem since

It’s got to be excellent value for money as you could part it out and get your initial outlay back and then some, though as I like the Q7 SUV I hope you will continue and find the leak(s), have it mot’d and use it as your daily still 👌🏼

If the blown fuse has blobby ends to the break it’s an overload, if it has clean ends to the break it’s a short circuit. The mats you can wet vac and put carpet dye in the wet vac water to stain them back to grey.

Looks a good one for a grand ,about time your luck changed get the soapy suds out you’ll soon find it good luck lad 👍👨🏻‍🏭

Love you're honestly regarding the door. We've all been there 🙂

Another good one again. Looking forward to the next video.👍

The original compressor on my CLS jammed on, which overheated it and resulted in it melting the power connector. It still worked after this but it got progressively worse. If you've ordered a new compressor you should probably still fit it

👀looks like it's might be a cheapish one for you fella✌️😎👍 buzzing

Vehicles with the steering wheel on the right, and some making their way to where I live as reconditioned units - I'm subscribing to this channel. --Petaling Jaya, Malaysia

Had the same problem with a merc w205, fuse blown quite a while back replaced it along with the pump because it was seized. After a few months the car came back because it was losing rear hight, replaced both rear airbags and did solved it, it was a tiny leak that wasn't always showing up

On the land rover ones there’s a big rubber o-ring seal that goes we used soapy water in a spray bottle. Aftermarket bag kits aren’t to dear if worst comes to worst.

good evening... a question... what pressure must the compressor generate to be able to lift the car?

Really enjoy Your videos. Im a audi lover. And shows a few already

The left rear air strut is bad and makes them all leak . I had a allroad and the corner that leaned was the bag that leaked . I got them at airnot industries and they come with lifetime warrenty . I love these q7 s ❤️

Replace the rear airbags I got cheap ones off eBay £200 they worked a treat

I clicked on this video wondering if you'd mention towing capacity, and you did! I've been on the hunt looking for a vehicle with space enough to carry Tools + 4 Wheels (and fitted tyres), as well as have weight left over to tow up to 2T at least.

Watching this video only to discover that green TVR Cerbera hiding in the back ground of the garage! Best of luck to ye mate and thanks for the vid. Ex Tvr Tuscan S owner

Always entertaining... Thanks for sharing...

Wow impressed 👍 you have a car 🚗 that starts …. Thats a change dean 👍

Hi dean car looks cheap as for your presentation you are very good clear and knowledgeable,don’t try to fit everything into one video keep the audience captivated Suggest you check out mat Armstrong and Chris slix I will enjoy all you’re videos I would like to see more rebuilds etc even up grades and car trips with mrs and kids keeping it real

Hi there, may I ask approximately how much you pay for your unit and where you found it? I've searching high and low for one for quite some time now

Its the self leveling valve moudule. Common fault as it is a service item always neglected. They get corroded over time and leak air. The item cannot be refurbished as it is sealed. You have to replace it. The pump has over heated because its not meant to come on that often and it should not run more than 2 minutes otherwise it will overheat.

The compressor piston is normally the culprit, £30 rebuild kit and easy diy for fix 👍🏼

May have been mentioned in previous comments however maybe try a smoke generating machine doo dad (used for vacuum leaks etc) to find the leak(s). Just a thought 😁🤔

Another great video. You could do a video fixing a Little Tikes car and we would still watch.

Dean what is the diagnosis tool you are using

I had a ABS ECU failure on an A6 2.5 V6. Audi said 1500 for the part and probably same again for the labour. Did a bit of googling and found a place in the UK that reconditioned the ABS ECU , £52 GBP and a video to show you how to fit it in 45 mins. bba-reman was the name of the crowd who reconditioned it.

Dean you got a bargain it might be the pump letting by 👍🏻

What an absolute steal! Good effort 👌

Stumbled on another good channel...I SHALL SUBSCRIBE!!!

Decent car for the money 💰 Which TopDon diagnostic tool is that? Looks good how it can run through the system details in depth

That's very cheap and a great car to fix would love to see you get some good performance out of it

Just swap it out for conventional springs and shocks save yourself and everyone else the hassle! Good luck bud

Full tank of fuel a bit suspect. Hopefully no faulty fuel pumps

Common fault on these is an intermittent sticking relay, which is probably why the fuse blew. Located under the drivers side dash.

First watch, good video will continue. 👍👍👍👍👍👍

Perfect for parking as close to the supermarket entrance as possible. Clear coat it to preserve that 'weathered' look.

Great Video, Can i ask what your diagnostic machine is please

got a similarly priced compressor for my CLS. Worked normally and looked identical to the original

Ah, the good old german pneumatic suspension problems 🤣 Depends if they have a one way valve fitted but the compressor itself can be the cause of the leak. The compressors piston just has a weird plastic/nylon sealing ring that wears n fails over time and most of these systems have a moisture filter that rarely gets replaced so you get corrosion in the system. Could bea simple sealing ring has failed on one of the lines or just the compressor is knackered but finding air leaks on these things is never a fun task. Good luck with it 😉

Do a height calibration for the suspension.

Great project! You’ll fix that no problem.

Replaced two rear bellows on 5 series touring for just £80 the pair, decent quality off Ebay, BMW wanted in excess of £2,000 for exactly the same job. And it only took me 3hrs. Oh and that was 18 months with no issues since. Lesson learnt.

@13:00 was screaming 'close the doors and boot', you got there though in the end.

Absolute bargain. Engine and box seem okay , can’t really go wrong with this this one.👍

Going through a similar issue myself. Bmw f11 2012, rear compressor for the airbags, new one off ebay 2 years ago now rusting from the inside out. Now have to buy a genuine one. Steer clear of the ebay rubbish. If it seems too good to be true, it probably is. Sellers don't reply when there's an issue with the item..

Who is the who's in the production? Anyway good luck finding the problem and thanks for sharing.

What fantastic result!

Just about to buy a Q7 my self fingers crossed there's no problems. Good thing is I'm in Australia and very little cars have rust here :)

What pick up have you got it would be better financially to run the audi if you can get running with too much cost

Yeah I think it's the check valve at the compressor that may have gone bad . And that's a first I have never seen a Q7 with no sunroof , at least here in NYC .(former Audi tech ).

is there a coilover conversion for them atoll
