| sorry this is not a reply, new to the site. I have a question, i drive a 2001 mercedes s430 and recently my esp and bas malfunctions came on so i had it scoped and it said that i needed to change the bas release switch that is on the brake booster. I changed it and everything was cleared then a week later the malfunctions came back and i've had it checked again and again and the dealer keeps telling me that the release switch is good. My question why are the malfunctions continuing to come back? |
