Hi guys,
Have posted this in the A3 Forum too but I think it is more specific to this one since VAG-COM is involved.
A friend has a few problems with the above car.
I took a quick look for him and retrieved VAG-COM fault codes as follows...
16621 - Manifold Pressure/Boost Sensor: Signal too low
16490 - Manifold Abs.Pressure or Bar.Pressure Range/Performance
16497 - Intake Air Temp.Circ High Input
I haven't had time to take a proper look yet but just wanted to know if anyone has encountered these before..?
With the engine running... when I reset the 16621 fault, the engine cuts out if only idling and dips when at constant off-idle engine speed. The other two, I am guessing, only appear when the engine is not running because it is not running. I'm assuming the engine needs to be running to avoid them because once reset they do not return unless I run the scan with the engine turned off.
I know there are a few obvious things to check and I will give it a good going over once he returns from holiday next week but a head start would be much appreciated if anyone has experience with this fault
Cheers
Tim
