Aud A4 3.0 DTi 2006 - Injectors Failing causing smoking at idle

[duncanhollands]

Hi I have an issue with exhaust smoking after idling for about 5 -10 mins so getting stuck in traffic is a nightmare.

After reading various forums I found this was a common problem with an expensive repair..

So I have read the read blocs and the results are as follows:

looking at the results I would assume Injector 2 & 4 are not good and could be causing the problem can anyone out there confirm this?

I'm happy to replace these two myself and do the coding but do the others look ok?

The Injectors are quite early ones - 059 130 2 77 AB from 2006, can I use later coded ones eg. BD ?

I know Audi and many Audi/VW specialists will say replace all 6, but for cost sake and the fact I can do the repairs myself is there any truth in this?

Many thanks if anyone can help.
