Last weekend while down in Cornwall I had the classic flashing glow light and the van wouldn't let me go above 1000 revs. I managed to check it out with my mates vagcom software and it said there was an intermittent fault with the electric throttle unit. We managed to clear it by...
every so often (becoming more often) I can be driving my 2.5tdi 88bhp and the heater plug light (coil on dash) briefly lights up, and when it does the van drops power - instantly.
does anyone know what this might be?
