Ah OK, yes I want the injectors to be happy in the engine ;) Perhaps they are not in a happy spot ha ha. I added to my above post at the same time you responded. You ever seen injectors with 6 character adaptation values stamped on? If so, what values were in VCDS, like for like or that zero on the end...

So far here in the USA I have only seen them with the exact characters on injector with the same in adaption input.

What I am considering is.............. blanking eeprom data, and just installing random experimental values, to see how they change operation

Ok here is an update on my situation.

All together I sourced 4 injectors from a lower mileage scrapped vehicle, took a risk I know but thought it was worth a shot to see if my problem characteristics changed or fixed themselves.

After some issues and damaged hands (due to not having the correct pulling device), changed all injectors on my engine. Adaptation of injectors rejected 6 digits so I did use the last character as zero which corresponded with the convention of before the changes took place. All adaptation changes were accepted and cross verified through VCDS. Then I started the engine and did notice it running smoother right away. Tried pulsing the engine up to 900rpm and dropping down to try and make the idle 'hunt' and it didn't. At worst it dropped to about 650rpm and recovered right away to 780rpm. In my opinion this is normal.

Results after the change:


Problem now sorted, time will tell whether it's gone for good.:cool: Thanks for your input.

I seem to be having the same problems. Did changing all the injectors sort this for you ??

Hi,

Yes replacing the injectors fixed the problem for me.
