A brilliant video. After spending hundreds of pounds on airbag modules, I watched your video and sorted the Airbag light in 30 mins. Thank you.

Another common airbag and serv fault rarely discussed on KZfaq is the rotational connector behind the steering wheel for the driver air bag. It's also called a squib or clockspring. It wears out and one wire breaks giving an 'open circuit' fault. Its a cheap replacement too from an ebay secondhand dealer.

Am surprised you don't have more subscribers as all your videos are very detailed unlike some youtubers who edit out the important bits.

Great video! I love the way you explained those sensors under the seat, this is a problem I need to fix on my Clio.

The cable behind the wheel was loose and your tips fixed my problem, thank you very much sir!

Thanks old son,gotta kangoo some garage tried to blag me for full replacement coming up mot,seen your vid am impressed and very pleased you saved me at least 500qd,thank you very much

I am impressed with the clarity of the explanation. I tried the binnacle connection first-no joy. But wiggling the grey connector under the seat sorted the warning lamps. That saved going to the next step of buying a side impact sensor. Thanks!

Had the same problem on my nissan kubistar service light and airbag just checked the connection under driver seat as soon as I gave it a good squeeze the lights went straight out. Cheers for the great video very helpful🙂

Great video mate you can also use a resistor in the place of the senses to see which one has gone

Thanks I've subscribed straight away i just bought a clio 1 5dci got that fault air bag and service will check thanks your amazing 10/10 ,Neil

Nice bit of diagnostic kit that. Worth the cost if you have different types of cars on the drive too 👍

Thanks for making this video. First time I've had this light off in 11 years of owning a clio. Replaced the crash sensor.

Thanks for this video. I had the same problem and tried the first option. Wriggled the connector underneath the passenger seat and gave it a little tap and it solved the problem. Both Service lights and Airbag lights have cleared. Thanks

Just an update lad, new to this driving and car fixing. A wiggle of the clips Under the front passenger seat sorted my issue many thanks

Hi Martin had the same on my 2003 Clio, tried them checks but mate had one of those testers, yup passenger side censor went down the scrappy got it for £10 all sorted that was 3 years ago love your Vids PS got a 54 plate 2005 love these little cars. Your tutorials are priceless thanks.

Good video this thanks pal. Answered a lot of questions for me when my airbag & service lights came on recently.

Well done matey. You've just saved me heaps on expensive parts. Your video really helped me out and sorted out the problem. Nice one matey :)

Hi Martin, you've made my evening! My son has this car (06 model) and we've done exactly the same as you and wiggled the grey connector etc to no effect. We hadn't heard of the connector you found (that was faulty) so that has to be it! And yes that has to be worth 15 notes on eBay. Cheers buddy! If that works we will be over the moon as otherwise it's his ideal first car. Quite agree with other comments on here regarding French car electronics - I had a C4GP and all the warning lights came on one day even though the car was still driveable. It turned out that the front screen rain ducts (tubes carrying rainwater away from the windscreen and supposedly dumping the water on the road) actually had caps on the end that presumably were designed to open when water built up behind them - wtf?????? Over time the crud from the road meant that the end caps collected a sufficient amount of dirt to stop them opening - with the result that they did fail to open and the water built up behind them and eventually overflowed into the engine bay causing electrical mayhem! Thankfully it all dried out and we were lucky. I did however take those end caps off (right underneath the engine, 2 of them) and loads of foul water poured out - French overthinking there... why put a cap on a tube that has to get rid of the water? Anyway, sorry for the long comment, but thanks again as I'm sure your diagnosis could be the problem for our Clio. Cheers! Mike from Sandhurst.

This video has been a god send, thank you so much for posting it.

french electrics im help my brother with his 307 is annoying to be at best i use elimination like you and the reader ebay or breakers is great value great video again martin m8

Enjoyed this. Here I am with 9500 quid worth of diagnostic tools and you speak of that little launch uni as the proper stuff. ha ha well it solved your issue and to be honest, it looks alright. Thanks for the educational video. Im a mobile mechanic, auto electrician, auto locksmith.

What fault code do you get from the under passenger seat connector problem? I got DF075 (Passenger Front Air Bag Curcuit 1, open circuit) along with airbag warning light on ..

It pays to get the right equipment . As you were saying its pure guess work. Great advice and look forward to part 2

Good video Martin. I wonder how much Renault would’ve charged to fix that job. A few hundred quid I reckon.

you should swap that sensor with the drivers one and make sure the fault changes to drivers just to be sure

Big help this: thanks. My daughter’s Clio had the same dash error lights. I’d narrowed it down to the connectors under the seat, but didn’t know about the dash binnacle or the pre-tensioners. Disconnected battery, waited for a couple of hours and liberally sprayed SWITCH cleaner, not WD40, and fired her up. All sorted 😎👍

My clio is 16 years old, leaking sunroof, airbag light on, heater motor blew, fan belt went, drivers door doesn't close right. I have no fixed all these things myself in my driveway with no experience working on cars at all.. threw in an oil change and 2 droplinks.. flew threw mot. Happy as Larry.

Brilliant, the under the seat method worked for me, cheers mate

Great summary of the different fixes, cheers mate hoping this helps with my kangoo!

Gonna get one of them cpr thins as well,dint need one this time your vid was good enough but it sounds good for the rest of the wiring should I get future probs🎉

Thanks a bunch. Fixed mine by wigeling that connector at the back of steering wheel.

Fixed my airbag issue. Nice one

Very good teacher. Thanks.

Very useful video thanks!

How much was that obd scanner Martin? & does it work on all makes? Another great video. Thanks 👍

AMAZING fix. 30 quid on ebay now. was i lucky picking the left side, is there also the same part on the right side

Great vid Martin 👍 good diagnostics.A handy tool for airbag diagnostics is a srs emulator it basically emulates airbag resistance idle for testing airbags,pretensioners, clock springs

The old intro back on your video 😁👍

martin could you please tell me, where you got your scanner from, and what price, i did see something saying 129? ,also what do you think of it, give us another video using it....have a good day

Nice one.. some good fault finding there. Those sensors are a pain, especially front and rear ones that live outside the car.

Just wanted say thanks. Turns out it I had to do with just disconnect and clean the connector and problem fixed. Thanks

Thanks mate, I bought one of them kits. Quite expensive but found out I got fault DF241 - Passenger's seat base/lap belt circuit. I will take a look under the seat tomorrow and see if I find any loose wires. :) I guess the kit can be used in the future haha

Brightly clear i will investigate seams to be the tensioner open circuit for me

I had a 2002 Renault Clio, the airbag light would come on first thing in the morning and would go away after a while. The code was something like 'power supply voltage low' turns out it was the battery and alternator causing the fault believe it or not

This did the trick for me. Thanks mate!

hey. i have the same problem. Do I need a diagnostic tool to let the light go out after the bug is fixed or does the Airbag light reset automatically? thank you good video.

Great video. Very clearly presented and good fault finding. Is the Clio 3 2008 prone to similar issues?

Shocking electrics on Renaults probably the worst out there 🙄, no pun intended 🙃

Hi! My Clio 2 had the same problem of the 2 warning lights,service and airbag then they turned off all alone. Yesterday I was parking my car and I heared a clack noise coming from the steering wheel, like something inside the steering cover was making contact. This morning went up the 2 lights again. It must be that contact you showed! I have to check it! Thank you!

Good video well done, for a diy'r with limited tools and equipment that was good

@retrorestore - have you ever seen a 'no computer' - 'computer voltage too high' fault on that reader? I have an icarsoft rtv1.0 which im using on my 2000 megane

Wish you could of given the part number,great video btw

Great video, will cheaper diagnostic tools still read the fault codes for airbags?

Thanks to tou I solved my driver airbag issue !! Fu***ng connector behind the steering wheel …

Very nicely presented, however i am more interested in the trotter van project. What’s happening to it?

Excellent video!BTW I would like to ask you something. A friend of mines owns a 2002 year model.He has the same problem.A few years ago he went to a Renault dealership and they cut-and then resoldered-the wires under the passenger seat but still no luck.Service and airbag lights are still on.About a week ago he took it to another Renault dealership and they told him that all 4 airbags have a problem and they need to be replaced. Is it possible?I highly doubt it because it's a little bit weird to have 4 faulty airbags at the same time .Is there any chance that the lights are on because of a blown fuse(airbag fuse)?He hasn't inspected the fuse yet.Also,the task you do at 2:35,is it safe to do it like you do or is it better to remove the negative cable from the battery(you didn't remove it because I can see the immobilizer light flashing)?Finally,considering that the "trick" with the passenger seat sensor didn't work out,if we check out the fuse and it's not blown and we push the cable like you did at 2:35 but the problem still exists,will a new squib resolve the problem once for all?Sorry for my long message!!!

The Peugeot 306s have problems with the door looms, its a design flaw in the loom. The loom physically snaps where the loom comes out of the bulk head to the plug into the door. It was more common on the old mk1 306s and I think mk2 306s, All you have to do is extend the wires, and replace blown fuses. Just another heads up if anyone has problems with door electrics,

Well done Martin keep up the great work

I used 2 resistors (3,9 Ohm, 5 W) to short-circuit the Yellow plug behind the wheel. It worked 🤟

Excellent diagnosis.

I had Renault once, would cry myself to sleep at night.Replaced a sensor every other week then came to my senses.

Great work. That would have cost 100s for a garage to sort. Prob have young lad on it just replacing everything.

awesome video!! Where your accent from, mate?

great vid Martin had the same issue's with a clio and a megane I had many years ago ,put me off french cars lol. atb Steve

another great video martin keep them coming

Wiggle it worked. Brilliant

my clio has an airbag fault. I hear door clicking noises and door unlocks itself when im driving and airbag light comes on. If i pull a thick bunch of wires wrapped in a coil under my drivers seat the light goes out. any ideas whats wrong. its a mark 3 1.2 16v clio. garage had a look and it says intermittent fault on computer.

What diagnostic device did you use? I've used two different OBD diagnostic readers now and neither will read the fault.

I love your channel my Clio 2003 1.2 has the service light on but not airbag light 🙄

I think the sensor is an inertia sensor. It detects side impact I believe. Great video Martin that Launch looks like a great tool how affordable is it?

999thenewman, I agree. I would never buy a French car, I'm a Vauxhall man myself. Great vid as per usual Martin, handy to know all these diagnostic issues 👍

Thanks for the vid Martin.

The CRP129 is OK to read basic codes and can be picked up for less than a hundred quid. For best value in their range I would opt for the CRP touch pro. Full android touch screen op system and has .. almost .. dealer level diagnostics on most cars. Can be bought for a tad under 300 quid but worth every penny. Quick note about sensors .. buy the best you can afford, OEM if possible. You can get burned with cheap aftermarket stuff and end up loading up the parts cannon unnecessarily.

hi sir i have clio 1.2L has service light and air bag light on ,but couldn't fix any mechanic ,i tried to put bypass but still on , my question is ,passenger and driver side impact/crash sensor r both same part code numer or different , i havnot change passenger side sensor which u tell us in vedeo but looks like it already changed,

I would get another one for sure. But I would also take that "defective" one apart to see what makes it tick.

Good job. Not sure if you guys can get a diagnostic device called BluDriver. It's a scanner where you plug in a small block to the engine light port under the dash board. You then sync it to your mobile phone using a Bluetooth connection and read the codes on your phone. The software is free to download to your phone off the 'net. It works great and you can read and/or clear the codes right on the phone. It's pretty slick! The whole thing cost me $100 USD.

Serious question was the lights on when whent through mot as wouldn't it fail if airbag light on

Did you know if this came up with a 180 code? Mines say passenger seatbelt pre tensioner and passenger side crash sensor

Thank you very much for sharing!

yes same problem with mine renault, just reached 61k mileage

Very informative.

Helped me out thanks a lot !!

Top man👍

thank you for the replies...

Thank u so. much sir abs light off now

Life saver🤝

Good info Martin.

Great video. BUT you forgot to mention the part name and part code. I can't find it eBay.

Slightly off topic - But....is the bite point really high on Renaults, specifically MK3 Clio??

Martin, Great fault finding a 15 pound fix i wonder what this would cost with a renault dealer lol, Cheers Dave.

Hi Martin ' great video, can you tell me how much that code reader was please, thanks

The sensor causing the problem is Bosch lol

hello sir ,i have the same problem clio 1.2 ,2005 ,i couldn't found that sencor on ebbey

Nice video friend, thanks

If I cut out all the connectors and solder them, would i also need to delete the fault code to make the light finally go out?

I did'nt see were or how to get the side-sensor out? Some help please? 🙏🙏

When we did our training on airbag systems, they told you to disconnect the battery and wait 20min for the system to lose its charge or you could set the air bags off. Might be something to watch out for, wouldn't want to see you eat the code reader if it went off!

It's a Renault. There's your problem right there.

Hi martin, i have the same problem with my renault clio, could you comment the item number for that sensor please :)

Shared Martin 😎😎😎
