Audi A3 2006 BKD engine. Can the swirl flap be removed permantly and coded out so the DTC doesn't log? Will removing the butterfly and leaving the pivot holes open cause an issue with gumming up and possibly impair air flow?
The mil is on and there are 2 DTC,s logged.P2102 & P2100, not integrated with a VAG tool. The engine has a slight overrun / shudder on engine off. Which fits in with the swirl flap is jammed.
The car is a 2006 A3 2.0 tdi with the BKD engine. Covered 110k miles.
Oil changed twice a year and the car covers mainly longer runs and regular fast motorway journeys for 2hrs +.
I will check the fuses and the throttle assembly, pots etc.
One of my collogues mentioned a lot of cars have twin throttle pots and the DTC is logged when one fails, at this point it is only a matter of time before the second one fails and leaves the car stranded.
I will leave feedback when I have found the issue.
Been reading through the VAG forum, think we are talking about the same thing. Quote for DTC's P2102 & P2100 "Its known as an anti shudder valve or inlet manifold flap not a throttle body as such". Its prone to jamming open when it get gummed up, has been known to jam closed and stop the engine from running. I think it probably could be removed but I wanted to check. Will also have to code out using vagcom to stop the DTC from logging, but don't know what the code is.Have seen it for the EGR.
I would like to rate your service, you did respond quickly and dialogue conversed freely, but due to the several names for the same component the original question was not answered. The component is just to stop the annoying Diesel overrun on ignition off, but it probably isn't advisable to remove the butterfly and the component would have to be removed electronically to stop the DTC's. If you agree or have a solution I will respond to feedback.
