im a forum noob. I own a 2003 A3 1.9 TDi sport. Recently I have had a few problems, new door lock and new window regulator but to name a few. Everything is fixed bar this>>>
When I am driving along and I start to accelerate and reach high (ish) revs, the car electrics seem to restart, mpg trip computer etc all reset, even the fuel gauge shows a different reading to what it was prior to reset.
I imagine this must be a loose connection which is being loosened further whilst car accelerates and engine moves a bit. My problem is I have no idea where or how to check for this loose connection.
Come to think of it there is one more thing Id like to ask, sometimes when I go to brake the pedal is really stiff and car takes a while to slow. If i quickly tap accelerator with clutch in then just the brake again it is fine.
Many thanks in advance for any replies at all.
