Hi all
I posted about 6 weeks ago with a 311cdi with 300000 on clock. It was going in to safe mode every 5 minutes but would only show up as low charge pressure on the computer. It was also backfiring sometimes (see previous post for full symptoms).
Just thought i would update for those who follow these things and in case it saves anyone else a few quid.
Independent specialist had it and claimed it was ecu. It wasn't. Merc had it and changed high pressure pump and a couple of other bits as well. It wasn't that and has steadily got worse. Have carried on working with it in between visits to garages and it has deteriorated to such a point that it is fairly undriveable.
Merc have it again now and have got down to the head having gone. This was fairly obvious to me in last week as things had got that bad and blatantly head like although personally i think that there is still an underlying problem that has forced me to drive it in such a way (keeping revs high all time to stop safe mode coming in)that the head could go and i doubt they will ever tell me what it is.
That brings me to point of my post.
I am not letting them do the head i am putting a new engine in it. I have already spent close to 1100 quid on things and time that were going to fix it not to mention the lost revenue and i can't justify taking the risk that merc are right this time. There is little or no comeback if it isn't the head they would just say it needed it anyway so i am paying 3 and a bit grand for a new warrantied engine and peace of mind and hopefully reliability again.
I may well be wrong but i would strongly advise anyone in my position doing such high mileage in an old engine not to keep throwing money at it once it starts to go wrong because just reading some of the threads on various sites there are about 10 common causes for what happened to my engine and it would cost a lot more than 3 grand to go through them all.
It's got to be worth 3 grand just to stop the embarrassment of the french of all people pretending to hold their noses from the fumes as they go past me!
