(Gas pedal down) car not acelerating.
« on: December 24, 2021, 09:13:30 pm »
Sometime on my way to e.g. work when i accelerate (press gas pedal) car is not speeding up and looses speed for some second, but after it works again fine.

My car is a GOLF 5 GTI 230hp after some mods, and a chip tuning, down pipe, exhaust and spark plug switch to new, blow off ventill etc.

And sometimes I have an occurring problem that my car is not accelerating when I press gas pedal, but only fort short time than it works all week perfectly fine.

I am a newbie, and found this forum today. So if you had something like this, or you could know what it could be. Please write an answer because I can't sleep that my dear MK5 have some issue.

Thanks for everything.

sounds like it's going into limp mode.
you'll need to get the car scanned with vcds or the like to see if any fault codes are stored.
Without traction power is nothing!
