2000 X 1.9tdi AJM Engine Limp Mode / Lumpy / smokey / Poss Injector
Getting fed up with my A4 B5 and now starting to think about replacing as more and more wee things start going wrong. It has done me 6 years mind you and owes me nothing now but still has been too good a car to me to dismiss now.
Anyway latest is that last night whilst on a short drive I heard a bursting noise which I thought was a tyre blowing so stopped to change the tyre. When I got out of the car the tyres were fine. When I went to drive away I had no revs and the engine stalled. After reving pretty hard I managed to pull away and then get the car home.
Now whilst idling the car revs to 1000 rpm and then drops to 800rpm and then back to 1000 rpm constantly and hisses at me when I rev to around 2500 rpm & above. Also when driving it seems to be in constant limp mode and is def. smokey (grey). There is also a smell in the cabin which I'm not sure if its diesel or oil. I have looked at my vacuum hoses and can't see any degradation. I replaced about half of them last year when I was having pressure / power issues (which rectified the problem then).
I have connected it up to my third party diagnostics cable with VCDS-lite free version. I did initially get the 17964 - Charge Pressure Control: Negative Deviation (intermittent code) however after clearing the code this has gone.(this could be historic) There are no other fault codes registered and this error has not came back after a very brief run.
Would I expect to get a fault code for a faulty injector ? Do you think it is likely to be a faulty injector ? Is there a way to check ?
Thanks in advance for any help.
