Hi all, Can anyone drop me a line on the below, which I have just been advised by my indy on a diagnosis visit (W211 270CDI, 53/2003): 1) I have the glow plug light on most of the time. I think I can recall this starting when I travelled through some really big floods recently. Indy has advised that there is a problem with the output stage and they have said I need to replace the controller and all glow plugs. Having been reading on here and googling, it appears that the glow plugs are pretty much DIY (with difficult access, maybe removing engine cover). Am I right in thinking the output stage is just the following part: 0285454032 ? This looks nothing more than a relay. I have been quoted £440, which I would love to not have to part with ! The car however starts and runs fine. 2) I have a small diesel leak from the pump in the engine bay. Not a big leak, but starting to make a mess apparently. Quoted £1200 to replace !!! Help . I am a pretty competent diy mechanic. Possible to manage this myself ? Thanks for the help.
