Dear Expert,
My car ASR light comes (yellow light, not RED one) up and the car goes to the limp mode. The service engine is also on and the faulty code 6 (Idle speed control inoperative, test electronic accelerator). I have to turn off the car and restart again, sometimes it happens 3-4 times in 5 minutes. The car is about 70K miles or 116k km.
After search for ASR light, especially reading Jim webpage I have the feeling that the Electronic Throttle Actuator is worn out.
I have changed the harness and stop lamp switch but it does not seem to help. I talked to a MB dealer in the part department and he gave me the price of the piece is CAN $2000.00. Pretty expensive eh? I also asked him whether you sell this part alot? He said at least in one year, he did not sell any (checked from his computer).
The question I want to ask is: Is this ETA the problem? or MAF Sensor or the rear speed sensors? (2 rear speed sensors each one is $311.00).

Any help would be much appreciated.
