Hi guys,

this is my first post on this website, if i have posted in the wrong location sorry
I've searched the thread for a while now and couldn't find problems like mine although some had some similarities.

i have a seat 1.2 TSI DSG 2015 model (sorry its not cupra :( ), which i bought brand new.
when i first bought it there was some problem which they referred to it as the 'start up OOO noise', and under the guarantee it got fixed, about 8 months later i have another problem

while in traffic, and the gear in drive (d1), when i do not press on the gas pedal it tends to rev up and down between 1000rpm and 2000rpm quite rapidly. i have a video but i don't think I'm allowed to post the link here yet as I'm a newbie. anyways, when that is happening and i do press on the gas 3 things can happen: 1) the car doesn't move and keeps revving up to 4000rpm 2) the car suddenly jolts forward, and I've had a few near accident incidents and 3) it just works normally.

I took the car to the dealership, while still under guarantee and they said they will send the report of the car to spain, as they've never seen such a problem and I've been waiting for about 2 months now for a response ....

So i was wondering if any body else has ever experienced this? or knows any solution? this is my first car and i have very little idea of how the cars actually work.

Thank you in advance


TL;DR

Car revs up and down (1000-2000Rpm every second loop) while in gear D1, during traffic mostly, and when i press it it either revs more, suddenly jolts forward or starts to work normally. been waiting for a response from dealership 2 months, they never saw something like it.. Thank you
