Thanks Architex,
I’m still trying to sort out my misfire issue and +25 fuel trim on bank-4 so looking out for anything abnormal.
I’m prepared to replace Lambda sensor and clean injectors but i understand the inlet manifold flaps can break off and cause the mixture to be off...

I’m taking it all apart again on Monday but VCDS activating the intake manifold test first and will inspect with a camera. Otherwise I’ll continue on to remove and service injectors and replace Lambda S1 Bank-4 while i’m At it. Fingers crossed...

Thanks again...
