Hello all, wasn't sure which section to post this one, Mods please relocate if ness!
So after a couple of years of trouble free motoring, my A207 threw a fault. Long story short, local indie hooked up to star and fault is connected to the passenger seat occupancy sensor being broken.
The fault shows a written message on dash as above + the airbag light is on.
I have obtained a new seat pad sensor from MB Grangemouth for £46 quid which seems to me a very good price with forum discount. I did read up on an emulator or such like to 'fool' the system that there is no fault (rather than replacing same) - I prefer a fully safe car myself so it must be replaced!
I'm confident to replace the sensor myself this weekend rather than the 4 hours labour quoted. My question is, generally is taking the seat out a real pain? Any general pointers or advice? Looking at the seat, it looks like a pretty std electric seat - unbolt from rails, take out and off the rails and take care re wires etc with putting back a reverse of taking out (taking care with alignment and wires etc), I've done similar in other vehicles before.
My main question is, with the seat out, the seat squab looks like it should be removed seperately to place the new sensor under rhe leather, then the single wire looks to go through to the bottom of the seat and plug in underneath. I'm not sure if one 'peels' back the leather or it is done differently, so any advice is welcome.
It doesn't look to be a real cow of a job though, just requiring time to remove it and put it back in properly.
By all accounts (including pro advice) once replaced, the dash warning and light will auto extinguish once it has done its checks.
I will post something on doing this job too, there is diddly squat on the web generally on doing the job, but it does seem to be a pretty common fault with these sensors.
Thinking back too and rather embarrassingly, I probably caused this myself by kneeling on the seat dead centre to clean the windscreen. The fault started pretty much immediately after that, went away for a week then came back in earnest last week! Less said about that, the better I think!!
Thanks all.
