After being hopeful and finding info on here I thought I'd solved my GTI's hesitation issues, but after more replacing parts it's still there.
The problem: When cold, the car has a serious hesitation issue under load below 2,500rpm, feels like misfires or a lack or fuel. Idle is also a bit lumpy. But take her over 2,500rpm and the hesitation seems to disappear but dip below it again and it returns. However, once she's warmed up there seems to be no hesitation at all, at any rpm!
Items replaced: Plugs, Coils, PCV valve. Have also disconnected the battery for half hour to reset the ECU.
Results so far: No Change!
I haven't been able to get it scanned for errors yet, and I'm not paying VW £60 just to scan it for me when they are still unlikely to know how to fix it. Hopefully vrsCarl will be able to come up but that's not going to be until July.
If anyone knows what else it might be, I'd be everso grateful as I really want/need the car to run right because it's getting me down now.
Thanks, Matt
