My car has also been diagnosed with a throttle actuator malfunction and the indy. shop won't use the parts that I provide. (As Phil did quote a good price for this part)
My '94 E3320 has been in for starting problems and they replaced the wiring harness which actually did look to be in pretty bad shape. A few months later I'm back with starting problems and they want to replace the throttle body actuator for another $2k?
This is my first MB - am I getting gamed or is this a fact of life for MB owners?
