Anyone else had this yet?

Basically, for those lucky enough not to have it happen, it effects the injector seals in most CDI Merc engines, usually it seems the smaller CC ones but may effect all the range.

You will know as the leakage creates a thick gooey (when hot) sludge around the affected injector. frown
You'll also get a chuffing noise and an odd smell, possibly.

You could take it to a dealer but you'll end up paying a shed load of dosh.
I've just ordered all the tools, injector puller, bolt hole cleaner, and washer re-seater thingymajig.
£200 but that's a snip (if it comes out) compared to dealer or Indy prices

In for a penny etc.

It is quite common on all Merc CDI engines, not so much the newer ones but they had their own injector problems as I understand it, mostly W210/211.

Car has 340k on an 07. (yes, I know!)

I assume you meant 34k!
Nope. 340k. smile


I've since found out that I've got Delphi injectors which are quite rare on this model, usually use Bosch.
I've cleaned all the tar off, it was not that bad, and have decided to let the pro's do it. (Indy)
