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.

Hi,

What did you plug it into ??

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
