Hi all.
I'm having a similar issue with my 2017 1.9TDI Manual Superb Estate.
for about 8 months now, warm or cold start, straight away or 30- 60 mins into a drive 10mph or 70mph My car will start stuttering as if the front breaks are rappidly being applied. stops when I take my foot off the accelerator. no error codes. Some time I'll have to pull over and turn off the car and restart the car it will happen straight away or it'll be gone and the car runs fine. It some times goes away if I up shift but not always. turning off front assist doesn't affect it. turning off park assist doesn't affect it. I've brought it to the garage twice and they could not get it to happen. no error codes with injectors or fuel related sensors. The only consistant charactoristic is it stops if Itake my foot off the accelerator. If I try to push through and increase the aceloration it worsens and the car goes into limp mode (I've not brought it back to the garage yet to check fault codes since limp mode). I'm not sure how else to diagnose without fault codes.
Has anyone else had this issue?
Thanks
Aaron
