Pudgie, there are a number of issues/problems which can cause the BAS/ESP warning to light: The actual CAB module could be bad, a wheel speed sensor may not function properly, the brake light switch or RCM could be causing your warning light to be on, or in the case of an SRT6 the switch on the master cylinder as well as an old worn battery. If you are near anyone who has a Crossfire first try to exchange the RCM from the other car and see if that will turn the light off. If not, your best coarse of action is to take the car to a European automotive garage and have it scanned as a 2003 SLK 320 if you have a base or limited crossfire. If your car is supercharged SRT6 then scan your car as a 2003 Mercedes SLK 32. Then clear all the codes take your car for a test drive and if the light remains on scan the car again for codes and they will help you buy the correct replacement part the first time. Otherwise, you are just guessing.
