Bless me Father, for I have sinned - it has been many months (or years?) since my last A2OC post!
We have been preoccupied with buidling a house, buying and enjoying an aging Lexus LS400 and more recently a 996Turbo - while the A2 has just been trundling around perfectly happily. Until last week! Then the Skid Control system decided to activate one of the front brakes while I was in the middle lane of the M1 in driving rain. This was then followed by lots of warning lights and bongs - though happily the brake was released. It reset after a short stop but then went again 3 or 4 times during the day - all in heavy rain.
On returning to the office on Thursday, my neighbouring garage had a good look and read the fault codes as being:
01542 - Yaw Rate Sensor (G202)
57-10 - Electric Circuit Failure - intermittent
01542 - Yaw Rate Sensor (G202)
27-10 - Implausible Signal - Intermittent
27-10 - Implausible Signal - Intermittent
We have previously had the odd spurious ABS sensor warning in wet weather, so I wondered if this was connected, but the garage say the wheel sensors and wiring all look ok - plus no fault codes for them.
So, the feeling here is to try getting a 2nd hand yaw rate sensor and substituting that. Are we on the right track, do you think?
If so, I need some help checking the part number for the Yaw Rate Sensor. I discovered this morning that my old copy of ElsaWin got uninstalled during a HDD crash a few years ago. It wasn't keen on reinstalling this morning - demanding a copy of Acrobat 4 and nothing else! I wondered if it might be quicker if some kind soul could look up the part number for me - if I PM the chassis number etc?
Cheers in anticipation!

PS: I have just noticed that I joined the forum in September 2004! Wow, that must mean we've had the car 8 years...
