Well, this is what happens. I end up with a perfectly good control module because my stupid technician decided that the car needed a new one for no reason so he put the new one in the car before doing the proper diagnosis and I can’t return it. this is the old one out of the car and it works perfectly fine. Nothing is wrong with it.. it is for W212 and W207 Mercedes Benz vehicles. Retail is somewhere around $640. My cost on it was just over 400$ I’ll take 250$ let me know. Thank you. If you want it shipped I take Zelle payment only.
