DSG Fluid Change -- Stupid Questions

[doughboy17]

... but I will ask them anyway. Thanks.

* When performing the clutch adaptation toward the end of the process, will that change a TCU Tune at all?
* It appears to take a while for the clutches to become "fully adapted" per VCDS. Is there a specific way you should not drive the car until they are fully adapted?

No the adaptation won’t affect the tune, it is simply recalibrating clutch engagement points for K1&K2 clutch.
You can just drive normally on the highway for 30mins in 5th and then 6th gear or just drive normally around town and clutch adaptation should finish after a few short drives. The process will continue even if you shut off and restart the vehicle.

I just did this job with VCDS and all of the processes wouldn’t complete the day I changed out the oil and filters.

I drove it normally for five or six days and then all the VCDS processes worked.

I have no explanation.

I was very precise with the temps and everything.

Anyway, it worked.

I had some insight into the adaptations, but done from OBD11...
main one that I found made a difference was the main pressure switch adaptation...it eliminated the harsh drop into 1st.
Also figured out that you should do those adaptations, then drive slowly and normally D mode and NOT go straight to hot doggin it in Sport...LOL...pressures were confused as hell when I did that.
Now, trans is buttery smooth. Especially when the fluid gets to temp.

Some other ideas on this:

you want to separate the adaptation steps (VCDS) into two different "stages":
STAGE 1:
- Erase counter for start/stop procedure
- Clutch valve calibration
- Distance sensor calibration

notes on STAGE 1: do this with everything cold (there is a lower temp limit, i think its' 20C). So, if you just filled up your fluid, and you've let it get to 40C+, you can't begin the adaptations yet, it needs to cool down). To help in diagnosing other issues, log the clutch pressures while these adaptations happen. The clutch valve calibration will have both pressures increase simultaneously from 0 to at least 17 bar. They should be nearly equal the whole time. If one clutch is lagging behind and doesn't hit the same peak pressure as the other, you have a problem.

STAGE 2:
- Clutch engagement point adaptation
- Reset start point of adaptation to factory settings *I don't include this in STAGE 1 because ODIS does this after the clutch adaptation

notes on Stage 2 - temp is 40C+, so you finished stage 1 and drove a few miles to warm it up to this point. Run the adaptation while viewing the relevant values in VCDS, this is important.

ADAPTATION DRIVE: As per Audi, it does not adapt anything in Sport mode. It will adapt in Drive, however you want to keep it in Manual mode; "do not left transmission upshift on it's own", says Audi. So drive in Manual, take it easy at first, and take a route where you have a lot of gear changes. Downshifts are never mentioned, but I think these help too. It probably will not adapt in one drive - turn car off and restart.

**Stage 1 can be repeated often and it will only help the transmission drive smoother. Also it will help your clutch adaptations finish if you're stuck. So run those steps again the next morning when car is cold, and check your clutch adaptation status again. Even after adapted, if car isn't driving smooth, go ahead and repeat Stage 1 when convenient for you. **

I disagree with the tune potentially effecting the adaptations. I suspect y IE tune was interfering. The best results I ever achieved were flashing back to stock, doing STage 1 and Stage 2, waiting for clutches to adapt fully, then putting tune back on.

ODIS does a notably different adaptation routine and gives better results then VCDS.
