Had my audi a3 1.8T 2001 for 2 years now and had it remapped a year ago. Ever since the remap I've had a problem where under full throttle there would be a kind of power on off, on off, up through the revs until i changed gear and then same again. I can hear the induction then DV release then induction again as it happens but obviously under full throttle i dont want any boost loss.
That's not all, after driving a random amount of time (could be 10mins, could be 2 hours) there would now be a power loss. Not so much limp mode but nothing like the usual power I'd get. The strange thing is if i reset my car (ignition off then on) then I would have power again until it goes off again and then a quick off and on and its fine again.
But wait there's more. If I'm gunning it, as in joining a motorway ofcourse, through 2nd and 3rd gear I'd have power and the as soon as i change to 4th i lose all power and foot to the floor the car actually slows down like its bogging down or something. Just for say 10 seconds then its back again.
I have scanned my car using VCDS and i got that 17705 pressure drop error.
After having this for a year i think it's about time I fixed it so any help would be appreciated.
