Good luck




Or your pulleys can be going they are plastic and they brake after a while. It's cheap and easy to change

1. SC tensioner pulley
2. Double idler pulley (metal and plastic one)
From what I have seen once the double idler begins to fail it starts throwing the belts off. ASP idler set is a cheap alternative to OEM replacement pulleys.
. Thanks for stopping in.1. It only threw the SC belt. Would that be consistent with the double idler issue?
2. Is ASP any better or lesser as far as quality vs OEM?
Do you have smaller S/C pulley and tune?
I have a 04 SL55 I have same problem . ESP malfunction visit work shop message shows right after S/C pulley installed and new tune.
The shop installed Pulley can not find why. Car does not have to move to get ESP malfunction message just turn on the car and depress gas pedal then ESP Malfunction messages shows. just like yours turn off the car then it resets itself. Star sysytem shows ESP does not commucate with Engine control unit. Shop thinks it may caused by tune So Contacted Eurocharged but they think it is not caused by Tune so Tomorrow I have an appointment at MB dealer to check it out. It maybe just coinstance but it happened right after the S/C pulley and new tune and I never had this problem before.

I put the belt back on and drove it a couple miles and everything appears to be kosher. I didnt romp on it too much but I'll give it a good driving here this weekend.
Did you try to Turn the ignition on and press the gas pedal to see if that triggers the ESP malfunction message on.
