Vehicle: Chrysler Crossfire Roaster 3.2 Auto 2005.

Hi Guys,

I'm having a bit of difficulty with the ABS and BAS/ESP lights constantly lit on the dashboard.

Car has failed MOT on this (everything else is fine - including brake efficiency etc.)

Upon failure the local independent garage diagnosed rear offside ABS sensor and this has been replaced with new, however the dashboard lights still remain. They've used 3 different diagnostic machines but cannot read any more information from the modules.

I'm suspecting I'm going to have to get it onto the STAR system to disgnose futher, however my local option appears to be the main dealer (which I'd like to avoid if possible). I'm hoping if any of you guys/gals may have any ideas before I go down this route.

The car drives perfectly, the spoiler activates as normal and the cruise control is working fine. I've tried the steering wheel reset procedure, wheel left to right etc. but still no joy. The following parts have been replaced/tested within the last 12 months (not specifically related to this problem, but just to give you an idea what's already been done):

New RCM module
New Bosch CPS sensor
New Bosch battery - outputting at correct voltage
New brake pedal switch
All fuses checked
Tyres have plenty of tread and tyre pressures are all correct, and there is no EML on the dashboard apart form the ABS and BAS/ESP lights.

I'm not sure of anything else that I can test/change myself. The ABS module has been removed today and I've given it a thorough cleaning with contact cleaner, but still no luck. I have the iCarsoft MBv.20 code reader, however this will not access the ABS system. I'm guessing that the culprit may be the steering angle sensor or the ABS module, but just want to check that I've not overlooked anything. If anyone has any ideas, or if anyone knows of a local independent dealer close to Oldham, Greater Manchester that has a diagnosic system capable of reading specific XF codes, it would be greatly appreciated.

Cheers, Ste.
