I took my 04 to MB dealer while ago. They told me I needed my ECU flashed. They told me it needed another ECU but I got home and read online. Flashing is only reprogramming it like a diesel programer basicaly. Was told it would cost about $1,400 or more. So just how much smoke is being blown up the blow hole here guys?
My car has been dead for about 6 months now. It was in limp mode last week I changed the connector plate it went perfect no problem there. BUT it still was in limp mode. Took it in today on a trailor and got the answers above. HELP!!!! I need to know what to tell them tomorrow morning, so please fast help herre.
