Hello from a newbie with an airbag light!
I've been driving my 2.5 156 for 5 years now and it's just decided it would like to keep the airbag light on full-time.
I've been messing around with Unidiag for a couple of days (during which I found out that I also need an O2 sensor) and I've just got to the point where I've read that I need to modify my KKL cable to speak to the airbag magic box, and use KWP71 software to read it.
Since the MoT's run out now I've decided just to pony up for a replacement ACU and see if that fixes it but for the life of me I can't find a direct replacement for sale or which part numbers are interchangeable.
The ACU number is 60658009.
Oh, and I've tried unplugging and re-plugging the yellow cable under the seat (which I gather won't do much until you can speak to the ACU and reset it). Is there a corresponding one under the driver's seat (RHD) as I can't seem to find it...
