I've read endless threads about this online but never found a solution. Was talking about it with a colleague and wondered if since it's so common, whether somebody else on here has run into the same thing and found the solution.
Basically when the car is cold it idles fine until it's rev'd or driven a few feet, then stumbles (rev needle dips) every 2-3 seconds a handful of times then settles down. If rev'd again it will do it again.
After 5mins of driving it's perfect and doesn't miss a beat.
So far I've:
- Changed the injector wiring loom
- Had all four injectors removed, tested and refurbished
- Cam lobes were inspected when the injectors were out, diesel specialist said the cam looked brand new
- Changed the EGR valve twice
- Fuel filter, various services
- Taken it to four garages and a VW specialist, nobody knows what's wrong
- Scanned for codes many times with VCDS - car gives nothing. Graphed as much data as I could but all I could see was symptoms, nothing that indicated the fault.
Also if I start with the aircon compressor is off the fluttering isn't so pronounced but is still there.
