recently fitted a brake light switch on my car which had variouse faults which was fixed, had the car scanned by vag com and now have a code of accelerator position sensor 2 signal too low p1633 g185, does anybody know if this can cause the swirly glow plug light, or have i fitted the brake switch wrong, even with the senor 2 down on the pedle the car still drives ok no unusal things happen it seems to be boosting ok, also the brake pad light is on which is down to the pad sensors as the brake have plenty left could this be the cause ?
forgot to mention its a audi a3 tdi 2.0 2004
