Harsh downshift from 2-1, occasional 3-2 (OB5/DL501, S-tronic)

[pixosk]

Hi guys,

I am quite depressed by this so seeking some help on forums.


DL501 harsh downshift in 2014 A6. Occasional 3-2 when specific conditions are met and almost every 2-1 once hot.


No errors, which drives me mad.


My fixing procedure to date was as follows:

1. Changed oil and both filters, adaptation (still harsh)
2. Changed all solenoids in mechatronic, new harness, adaptation, (except those in “tower” related to forks) (still harsh)
3. Changed dual-clutch, flywheel, all gaskets, new bearing - now still waiting to finish clutch point calibration within adaptation (100km driven, however already harsh)

This only happens when the engine/transmission gets hot. Its worst when hot and agressive stop is made at the same time.


Otherwise its silky smooth including all upshifts 1-7 and downshifts 7-3. No kicks at stop in D or R. Every gear follows order as it should, no skipping.


I am now waiting for Audi Dealer to get an software update if available (not sure if they will do it but I have only VCDS/VAG-COM). According to this article it may help but does not makes sense for me as everything has already been changed (Page not found - Transmission Digest)


As I am a little bit skeptic this will help I am proactively looking for next steps I can take. Any ideas please?


Its my own car in totally superb technical shape at 225 000km. No issues from new until approx last 1000km when kicking starts.


Thank you for any advice.
