I was charged $629 for Mercedes Benz MacGregor to attempt to code the headlight on my car. They were unsuccessful and gave me a quotation to replace the headlights for $2300. I took it to an aftermarket guy who coded the existing headlights for $200. Incompetent technicians and service manager t this branch of Mercedes and they refuse to refund my $629 when I came back to tell them that someone else coded the existing headlights for $250. what a scam they run.
