Hi all, my newly acquired 2007 SRT Coupe has thrown up an engine warning light about 3 hours into a 6 hour trip. Initially this was followed during the drive with an intermittent BAS/ ESP warning. The car de-powered itself, but otherwise drives fine and no other issues.The engine light is on, but the BAS/ESP has not returned during subsequent short drives.

The original owner had been in touch when I was buying it to say a smaller pulley was added to the supercharger and the car was tuned to increase HP.

My experienced long-time mechanic, who has owned a Mercedes SLK previously, read the 9 error codes (all were labelled "Stored" btw). They wouldn't clear. Before he starts working backwards through them to eliminate each sensor or mechanical issue, I thought I would check if anyone recognises the first errors in the sequence - which may be causing the rest.

Two errors in the SLA were cleared: 1 ) CAN Bus circuit faulty and 2) reverse lamp supply circuit open

ESP errors
1 - PCM Coding Incorrect
2 - CAN malfunction PCM Timeout
3 - CAB system undervoltage
4 - Steering angle sensor malfunction
5-9 are steering angle related + ESP torque interface locked.

The mechanic wondered if the PCM coding message arises from the tuning once done to the car.

Do any of these sound familiar to forum members?
