• How do I repair damage...
Hi
This car came to me with an intermittent Airbag light.
The light would come on randomly.
Scanner pointed to the driver side pretensioners circuit, and when I started to touch the loom and plugs under the seat, I was able to replicate the fault.
Watch the video to see how I have repaired this problem...
Hope you enjoy the video.
Any questions please put them below.
Like always, thank you for watching!

Hi, really appreciate your video. I have the same problem, intermitten airbag light on, and diagnosed with same errror code. Could you please describe on how to detach the pins from the connector? Thanks

[@LMAutoRepairs]

Hi
I can't remember now from the top of my head... sorry...

[@Rif-1921]

thanks for the video, I have scenic 3 1.5 dci diesel. I have esp turned on in diagnosis, yaw speed sensor comes out I don't know if I change the part, I have to do some configuration with the computer thanks

[@LMAutoRepairs]

Check the readings of the yaw sensor on live data... if is bad, then probably you need a replacement...
Yes, usually they require to be calibrated...

[@hantverkaren]

Hi, Thanx for this. One question though; Some recommend that one disconnects the battery before playing with the Airbag connector so as not risking the airbag to accidentally trigger. What's your take on this?

[@LMAutoRepairs]

Strongly advisable!
👍👍👍

Hi, Thanks a ton for making this video. Its very useful as I've this problem with Scenic too.
How did you remove the center storage? I have a scenic 05, the storage box in that is fixed to the floor. I don't see anything like that in your car. I could not undo the screw due to the front seats. I believe this needs to be removed first?

[@LMAutoRepairs]

Hi
Yes, if I recall correctly they come off first...
Thank you for watching!

Do you have a video of how to take car seat out. And disconnect the seat belt in the side of the seat connected to the seat??

[@LMAutoRepairs]

Hello, very helpful and clear videos. Thank you. From your experience, an advise please. The rear foglight wire runs via the R2 connectors (all dry and clean) to the UCH pin 6. At the R2 I measured only 4,5 volts. Too low to light the bulb. Next step is checking the UCH pin for voltage. The UCH switches the dash symbol on but foglight is off. Is there a relay or fuse invloved somewhere? Thank you, regards Henk NL

[@LMAutoRepairs]

Hi
No... the switching is done by the UCH alone...
If you have that low voltage at the UCH pin, perhaps the unit is failing...
Obviously, check that all the powers and grounds for the UCH are good as well...
Thank you for watching and for your comment!
