Hi, I am not yet officially a Mercedes owner but I am actively looking to purchase a c350cdi w204 and I am close to securing a purchase on an early 2011 plate.

While using this forum to learn a little about my next purchase it has come to light that there is or has been a massive issue with the blue efficiency injectors, so my questions are -

1- From what I can gather this issue has already been rectified and any Mercedes regularly serviced at a main dealer should not be concerned, is this correct.

2 - Is the fix permanent or still causing some members on-going issues.

3 - I am not clear whether this issue even affects the c320 and c350 V6 engines so if someone could clarify it would be appreciated.

4 - Any other issues or points to note regarding the V6 engine and C class w204 in general I should be aware of?

5 - What is the real around town MPG from other 320/350 owners?

6 - I haven't come across issues regarding the DPF but I know on some cars this has also caused major issues and cost for owners. Is the W204's DPF any cause for concern?

Any help very much appreciated

I'd love to help my friend, but we don't have the C350 cdi here in the states

No problem, thanks anyway. Dont US Mercs have injector issues and if not are all US Mercs V6 six pots or do you also have the 4 cylinder variant. It may be the issue is only present on 4 pot diesels.

Cheers.

Try the MB diesel forum further down the page.. I am sure they will help.

I would like to ask why do you want a 6 rather that the efficient & powerful 4 cylinder.

The handling of the 6 is inferior to the 4 because of the engine weight.

Have you driven the 4 cyl 250. ?

Hi, i will check out the diesel forum, thanks. Regarding V6 over 4 pot i have a couple of reasons. My main concern is the blue effiency injector issue which seems rife on UK 4 pot variants, although i cannot get 100% confirmation, the problem does not seem to exist on 6 cylinder models. My other reason is just basically satisfying a mid life crisis I would rather the duel exhaust exiting through the back, 264bhp on the c350 is more appealing than 221bhp on the c250. c350's in the UK are generally higher specced i.e leather, command nav which although can be specced on 4 pots are not so common and finally the engine noise on a V6 just sounds better in my opinion. Boys and there toys
