very new to the forum, i have a vw passat B6 170bhp BMR engine code - when driving normally it drives sweet but when hammering the acelr it judders like there's a lose of power or a miss and something is restricting it.
It happens in 2nd, 3rd and 4th gear not tried 5th and 6th as cant go that fast. the car has done 114k with FSH
and just recently had a crank position sensor replaced.
I have a friend who has plugged it on VCDS who can not find any issues with it at all - a while back a boost presure regulaor fault appeared up but when cleared has never come back.
The DPF has now been removed and has been programmed by a tuning company but the issues was there before the DPF removal and when a re map was done to the car whilst the DPF was removed he took it out on a test drive and found the car juddering woser like there was a miss so have taken the map off and left it stock but the issue is still there.
Please can someone help with this issue.
Thanks
