I've noticed that whenever I have the battery out, the ECU in the
engine acts up for a while; not controlling the idling rate correctly.
Is there a way to reset the ECU - my motor is an Audi Cabriolet 2.6 V6.
I seem to remember there was a way to do this without needing to visit
the garage? Does anyone knows what that is?
By taking the battery out, your ECU is reset to its default values. There is
then usually a manufacturer-specific process that involves a set amount of
time idling, followed by driving in a variety of conditions.
TBH, I've found that after a short drive, all the settings are re-learnt

magically appears in front of Chris Whelan:
That's the strange thing about all this; I took my motor out for a
30 mins drive but the idling still wasn't quite right it's as if it
was remapped 1000rpm higher than usual, and some times letting off the
accelerator pedal caused the engine to rev higher and then lower.
It was all perfect the day before.
I'll try again tonight and see if it's back to normal yet.
Ithink sods law of coincidence has got you there. (Coincidence possibly
involving what you did :-( ) . Bentley in the US will sell you a manual
with a proper wiring diagram or erwin will sell you ine quicker over here.
I was just about to post the exact same thing. If your car is drive by wire
you will probably need vag-com (or a visit to a garage) to re-align the
throttle body. I used to own a VW Golf V6 4motion and downloaded a copy of
the vag-com software. I 100% recommend getting yourself a vag-com cable from
the likes of ebay and downloading a copy of vag-com. I found it a very
useful tool in the time I owned the golf.
