On way home last night and the EPC light popped up on dash and car started to play up. When you press the throttle the car pulls normally then completely drops off like you've taken your foot off the pedal and the revs drop, lift off and wait a second then it kicks back in.
My reader isn't good enough to diagnose, but everwhere I'm reading is pointing to crank sensor, but i'm sure these either work or they don't?
Any tips?

My code reader doesn't recognise any codes for some reason
Changed crank sensor and brake light switch, both no good!

Re: EPC Light
Haven't changed the mass air flow so not sure if it's that. Changed all 4 coils, crank sensor and brake light switch still no good. Anyone else got any ideas? Ran better with fresh coils but still having trouble
Re: EPC Light
HI mate i had an issue where the engine management light was on and the traction control, it was the maf, all i did was nip down to halfrauds, buy some electrical contact cleaner for 4 quid, whip the maf off, spray the cleaner over and then let it dry, put it back on and after a short drive the lights go out and its been right as rain since
Re: EPC Light
Mass air flow changed and still getting issue, do you think the electronic throttle pedal could be at fault?

Re: EPC Light
I think that you MUST now get a proper scan tool that is full VAG compliant, ie like VCDS as you have now changed far too many parts in error.
Re: EPC Light
While waiting for my mate to bring down his diagnostics machine I took a punt on a camshaft sensor, the fault has now gone and I've cleared the code off and it hasn't come back yet so fingers crossed!
