Hi I've got a 52 reg 638 112cdi auto I bought a coiple of weeks ago, it won't rev past 3000rpm and has glow plug light/edc/srs lights on permantly. Plugged it in and said engine module not coded or faulty. Any ideas chaps? Thanks in advance Tim.
its not limp mode as far as i am aware .. i just bought a 112 cdi and thought exactly the same but i am getting told its a safety feature for when your sitting idle as it goes past 3000rpms when driving .. or atleast mine does.
If it wasn't SDS / HHT then you will not be getting the full picture, and if it does need coding, then SDS / HHT will let you do this :wink
OBD readers, Carsoft, etc etc are useless on MB Vehicles, been there, tried that, and ended up buying SDS :wink
Carsoft and similar will pull and reset a few fault codes, OBD stuff less, but that's it.
Think of it like trying to look at your whole street through a key hole :wink
HTH
Cheers Dave
