Forum rules


When you put a new thread up in the Workshop please put your car's year and model in the thread title, along with just a brief indicator of the problem.

Car Year - Car Model: Brief description of issue. EXAMPLE- 1999 9-3. Problems starting when hot.

Please also add as much information as you can about the problem, to your post.

This will help us to help you, without having to ask basic details such as what car you have.


Threads with non-compliant titles will be moved to The Pit Lane (in which no replies can be posted, but the OP can edit the thread - upon which the thread will be released to the workshop forum)

Nb. Generic thread titles for truly generic issues that genuinely are not model or variant specific (such as "how do I change the spring in an forge wastegate actuator") are acceptable

**The first 5 posts for new users require individual moderator approval (which they will only get it if they are in line the rules of the forum). Please be patient and allow time for that to happen, and avoid duplicate postings.**

Guys,

As per other thread, this car is being prepared for sale for my Daughter-in law. Periodically there is a 'bong' and the airbag warning light comes on. After a shot period - 20 seconds or so, it goes off again. Seems to happen more with a passenger in the front seat, but not always. Any ideas ?

Paul @ Kippen.

Could be the seat presence sensor causing the problem but you really need a Tech2 hook up for the fault codes.
Dont think it can be an airbag fault as such because it would be permanent and require a Tech2 reset if it was clock spring etc.

cja,

I thought it was strange that it 'reset' automatically. Like you I had assumed that Airbag warnings needed Tech II. Strange thing was that a trip to Stirling and back ( Mrs P @ K ) in passenger seat and it never tripped once. I wonder if something has 'reset' since I managed to flatten the battery to the extent that I needed to reset the clock. Time will tell, I'm doing a 70 mile round trip this afternoon. Might carry a heavy box to put on the seat on the return leg to see if it triggers again.

Paul @ Kippen.

Guys,

Further update. As I adjusted the seat to put the aforesaid heavy bag on the rear floor, the Warning 'Bong' sounded. Put the bag on the floor and moved the seat back. Warning off. Stayed off all the way there. Bag on seat, in rearmost position, on the way home and 'Bongs' only on braking. Not emergency stop stuff, just normal braking. Seems like a poor connection in the wiring around the front passenger seat.

Progress, I hope !

Paul @ Kippen

I had a look under the seat and there seems to be a black plastic 'box' into which the wiring disappears. There is also a 2 wire lead which goes to a connection on the central console side of the inner seat runner. This wire has a plastic attachment onto the under side of the runner. Put back in position.

The plastic box appears to slot onto two captive self tappers protruding through the cross strengthening box section. The retainers are worn and the box does not stay in place. I am wondering if there is a tilt switch in the box and it needs to be kept in a certain orientation to prevent activation. Anyone know anything about this ?

Guys,

Latest update. The airbag warning light came on on the dash so I thought. 'That's it' need a trip to Tech II. However, I took the seat out again and used some advanced thinking ( tubing over captive self tappers ) so that the 'box' fits firmly in place and horizontal.

Fired up and all lights off - ???? Job done, I think.

Paul @ Kippen.
