eratic/rough idle and flashing engine light

[donovan2123]

just had my cupra 180bhp remapped. Was fine for 1days then i got in to car today and it has real rough idle almost like its missfiring. Also engine light keeps coming on and going off. Any ideas guys?

Get it vag-com'd could be anything, so many sensors on these cars, to our advantage

I read that its common for coil pack to go on these vehicles after a remap? Any more ideas?

If you stick your head under the bonnet does it smell like a coil pack has burnt out?


Best thing to do is get it code read or put vag com on it.....not really much point guessing IMO......although my money would be on Coilpack or MAF
