Hi all,
First post and hopefully your brains can help me because mine is very confused!
A week or so ago, whilst on the country lanes at 50mph in 5th, i put my foot down and the car felt like it was stuttering or losing boost. First of all i thought i must have imagined it, however it continued doing it for the rest of the journey, and not just in 5th, it happened at low-mid revs in 3rd and 4th too, but mainly 4th and 5th.
A little hard to explain but it felt like someone pushing you in the back whilst running - or something slipping and then moving again. A light juddering you could say.
Anyway, after some research i thought it could be the DV so bought the new D Pistion type version and fitted that, and for a day it felt a bit better. Then nope it started again. It normally happens under hard acceleration and most noticable in 3rd through 5th. If i properly stick my foot down it really feels juddery in power, but still seems to pull well. It happens to a less extent under normal acceleration.
The car had a major service in May at the local VW dealer and they completed the 28F5 coil pack recall change then too, so i would think the coil packs are ok.
No codes or faults come up when plugged into vcds, although it is not a proper Vagcom, and no lights on the dash.
I'm really struggling to work out what the problem is - but will not be ripped off by the £90 an hour diagnostics charge the local VW dealer wants.
Car is a 55 plate (nov reg but i think pre the change as has the older style of wiper blade connectors)
Help!!!!! Any thoughts? could it be the PCV?
