My car used to go into Limp mod at 4k rev, but after today its hitting 7k rev
A3 - 51plate 1.8T
Can someone give me an explanation of why this has happened, becus I know nothing about engines
I've had my car for a year, and whenever I hit over 4k rev's it would go into limp mode (everytime), as tho it had been red lined
Did an airport Run today (snakes pass) and on the way back, i gave it a little welly, and it kicked a little smoke out. Since doing that (which I dont do often) Its now able to red line at 7k rev, it feels great, nice and roar-ey. Can anyone with knowledge of cars explained what may have happened?
ADD: I got it serviced 5 months ago
