Hello all,
I hope someone can help. My 2002 doblo jtd elx has had an intermittent loss of power problem.
When you start it will only rev to about 1200. If it stalls at this stage, it is really difficult to start and is just like trying to start a petrol engine with two of the spark plugs not firing. If you keep working at it it will gradually increase revs (putting out clouds of unburnt diesel smoke) and suddenly clear with a big cloud of black smoke. It might be ok for a while or it might just be unable to rev again. Sometimes it will go for quite a while without a problem. It does seem to have deteriorated to the point where it is like it most of the time.
I took it to a garage who has a testing system. He had it for a day and said he could not get it to play up and nothing was showing on the analysis (that cost me £115).
I was persuaded to take it back when a couple of days later it was playing up nearly all the time. He had it for a fortnight and announced that it was the air mass meter. He replaced this and told me it was ok. I went to collect it and left the cheque for £235 (is this a fair price).
Within the first mile it was doing it again. I will stop the cheque on Monday but don't know what to do. I have seen threads about the egr valve and wonder if this would cause the problem. Would it start off as intermittent? Also, what happens if you disconnect the air mass meter? If it is faulty, does disconnecting stop the symptoms? Finally, where is the egr valve and is it easy to remove?
Sorry about all the text but I am at my wits end.
Thanks in advance.
Richard.
