My son's 2.8 tip has been displaying a CEL and occasionally flashing. I told him
tonight that flashing CEL means shut it off and correct immediately.
He says that when it flashes it usually goes away quickly and is fine for a day
or more the repeats.
Tonight we were at a friends place who has a VAG system and we pulled the codes.
It was outside in the dark and cold so we didn't get organized enough to write
them down but as I remember it the codes were referring to 'misfire on cylinders
4, 5, and 6 (all on drivers side bank).
The engine runs fine and doesn't seem to be going to limp mode.
The timing belt was done with all associated things last spring. The 'optional
Audi external oiling system' of the 30 valves was corrected this week but the
CEL issue was happening before and continues.
Plugs were recently replaced.
Plug wires are suspect.
He is getting some noise from his cam chains. The CEL seems to be more common
when idling so I was thinking that the knock sensor (this engine has one doesn't
it?) could be mistaking the chain noise for pre-ignition.
My ride: 98.5 1.8TQM APR (faster than son's 2.8 tip)
