3.0 TDI injector help please

[mikeya4]

I have an intermittent idle issue where it feels like a missfire, I have read about measuring blocks 72-77 but not sure on how to read the data, can anyone help?
sorry for the sideway pictures.

I had rough idle issues with a big of smoke turned out to be an injector fault on low fuel / idle I read measuring blocks but others seem to compensate for it readings all over I had all mine pressure tested which I’m told was the best way.
Some clever lads on here who might throw some light on it good luck fella.

Thank you, I have had a price for pressure testings which worked out about £150, but thinking if I can diagnose one via vcds I can put that towards replacements

Good luck my readings were very vague that’s why I decided to get all mine tested but yes the testing just about pays for a new injector think mine was £186 and the new injector would need coding in.

Don't suppose you have a part number for your new injector? I guess its a different one from the original?

Not got a part no to hand but should have some paperwork.
Yes the early injectors were poor they’ve been superseded at least 3 times I got the latest part no/injector will check later.

Very difficult to diagnose a faulty injector with VCDS as quite often it's more than 1 that has an issue.
This is a very good thread with lots of info but even when you know a lot about reading the VCDS results on these engines it's very difficult to make accurate decisions. Probably the best thing to do is get all the injectors tested by a reputable specialist. Then go from there.

Thanks for this, I’ll have a good read. Do you know what compatible injector part numbers are or the recommended replacement part numbers are?
