I need to replace aam module 650 dollors at the dealeship . Can I get it done some where else for less ?
Esp/Bas light began illuminating after I had my front rotors and breaks fixed. Dealership replaced ESP module.
I have had this problem fixed at the Mercedes dealership four times and they can't seem to get it right. My brake lights never turn off which in turn makes my cruise control not work. Mercedes says the problem is a faulty brake light switch and fixes it. Within a hundred miles after the brake light switch fails again. I have only paid for this the first times which was around a $129.00, there after has been covered through the part warranty. It has gone out again and truely has become a burden to keep taking it back.
I guess it is the break pedal light switch. On 71 going south at 65MPH to a Rugby Game. With cruse control engaged the gas pedal failed to increase speed to overtake a car. Then when the cruse control was disingaged to test the gas pedal there was no responce from the gas pedal. Quickly re ingaged cruse control and drove the next 100 miles by cruse control manual increase/decrease.
Finally obtained a sllooollll response by gradually depressing the gas pedal. Managed to drive through traffic with only a few toots when starting off from trafic lights. Enjoyed the game checked all fuses and wiring. Restarted and now the ABS BAS ESP lights are on and the throttle is a near normal but no cruse control.
Apparently no ABS BAS ETS/ESP eithor because lovely 18yld Daughter locks up brakes in wet and low speed crashes into imoveable tree. Air bags don't deploy and insurance is rebuilding the beast.
