Slightly worrying occurrence happened this morning on my 1.8T A4 190. On my way to work 6 mile B-road then dual carriageway, got to the DC part in no real rush so was just ambling along in 4th, pressed on the accelerator and nothing happened utterly dead. Dropped into 3rd and it pulled away as normal. Same thing happened 1/2 mile down the road.
No fault lights, no spluttering, simply nothing which went away completely lifting off the pedal and pressing it again.
Something serious to worry about or just a dodgy pedal pot?
