Tsb 2017657/3 - Anti Stall Behaviour Is Gone!
I just took my car (S5, 4.2L) in for its 25,000km service. There were a couple of minor things I asked the dealer to investigate, including the fact that the once in a while the engine seemed to almost stall while sitting in traffic after highway speed driving; it would catch itself, the rpms would then jump and the car would shake quite a bit.
I actually had the car at the dealer in April for a few hours and had them check this issue as well - they replaced the air cleaner and strainer under warranty, performed some software flashes, but it didn't solve the problem.
When I got my car back yesterday, I was told there was an ECM software upgrade for the rough idle complaint. My invoice says T.B. #2017657/3.
Is the rough idle gone? Too soon to tell.
However, I can tell you that all of the anti-stall programming that prevented us from engaging 1st gear at anything between 500 and 1300 rpms is now totally gone! I can hold just about any rpm with the clutch depressed. The rpms don't jump up as I'm trying to engage 1st gear. I no longer have to adjust my driving technique between the S5 and my GF's A3. In traffic, the car has been completely transformed and is now easy to manage.
The dealer is (hopefully) sending me a copy of the TSB. I will post it as soon as it arrives.
