I recently fitted a stock hpfp with Autotech internals to my S3 Cdla engine and now car stutters and slows down as if engine is getting starved off fuel and on vcds it shows low fuel pressure .

So have others suffered the same problem when they changed theres out to go St2 and how did they sort it .

I still oy have stock fprv in not the RS4 one , now could this be the problem . Cheers EarsSat, 10 Oct 2020 06:35:29 +0000
