Possible tiptronic transmission problem?

[Nishinga]

I have a 2009 A4 2.0T Quattro with the 6 speed tiptronic transmission with about 90k on it and no idea of service history. Im 90% sure it is bone stock/no mods, there isnt even tints on the windows.

Recently I have noticed that slowing up to a stop that the car sort of jutters as it is about to stop.

Today I was at a stop sign intersection. Pressing the brake - releasing to roll forward - reapplying the brake. (again the car would again jutter as I was going) Once I was at the stop sign and it was my turn to go I let off the brake, applied the gas and the car would not move. I put the car in park, turned it off, turned it back on, put it back in drive, released the brake and it jolted forward. It does't have any problems just driving, only when it is slowing to a stop.

Any idea what i'm looking at here? Transmission control module? The transmission itself? Some sort of sensor in there?

I did some searching and didn't come up with anything conclusive.



Also
I checked the oil level on the MMI screen and it is just a hair above the minimum line, I have driven about 800 miles since the oil change. Am I still able to get the oil consumption test done? I don't know the history,so I don't know if it was attempted before or anything.



Any help/advice/information would be greatly appreciated

Ive heard anything from faulty mechatronics seal, to bad valve body, bad solenoids, to bad input clutches, and torque converters on these things. No clue what causes the shuddering. I get it randomly, typically when i drop into 1st on a hard stop.

Theres a TSB for this. Give it a whirl, its pretty common on the 6speed Auto 09/10 A4's.



Customer may report:

At startup, intermittent no drive when selecting driving mode D or R.
The vehicle can be driven only in 3rd gear (Limp Home Mode).


Workshop findings:


In rare circumstances, if the vehicle was in motion and the ATF strainer becomes loose, the transmission may go into Limp Mode and can be driven in only 3rd gear.
In cold conditions, the gearbox shifts with a delay. In hot conditions, suction noises occur.
The following DTCs may be stored in the transmission control unit:
‒
DTC P0730 (Transmission monitoring incorrect gear ratio)

DTC P2700 (Clutch A implausible)

DTC P2701 (Clutch B implausible)

DTC P2702 (Clutch C implausible)

DTC P2703 (Clutch D implausible)


Technical Background

Because of a design change, the ATF strainer can come loose from the guide of the ATF pump intake duct. As a result, air can be drawn in. Air causes the oil to foam, which prevents the clutches from closing completely.


Production Solution

Optimized ATF filter.



Service

If the complaint can be reproduced, proceed as follows:


1. Check the gearbox control unit for the above entries and create a diagnosis protocol.

If there are no faults stored but the concern can be duplicated, proceed to step 2.
‒
If one or more of the above DTCs are stored, proceed to step 3.


2. Check the ATF level per ELSA instructions.

If the fluid level seems too high and foamy due to air mixed with the ATF, proceed to step 3.

If the fluid is at the correct level and the fluid is not foamy, open a Technical Assistance Center (TAC) ticket and contact a TAC representative.



3. Drain the ATF into a clean container and remove the ATF pan.

Tip: Catch the ATF in a clean container and reuse it after the repair.


4. If the filter was found in the bottom of the pan, proceed to step 6.


5. If the filter is still seated in the valve body, try to remove it with light force.

When removed, if the filter seal remained behind in the valve body or is not fully installed on the neck of the filter, proceed to step 6.

If the seal is fully installed on the filter as shown in Figure 1, open a TAC ticket and contact a TAC representative.

6. Replace the ATF filter with a new filter according to the Repair Manual.

Note: Make sure that the magnets in the oil sump are not stuck on the underside (metal side) of the loose ATF filter and are not removed with the old strainer. The magnets must be reinstalled in the pan to protect the transmission from metallic particle abrasion in their correct original location.


7.If there are complaints of gear shift quality after replacing the ATF filter, clear the adaptations in the test plan and then perform the GFF or Guided Functions Adaptation Drive.

Thank you for posting this!
I've been searching tons and finally came across your post which perfectly describes the issue i'm having!
Man, dig far enough and with the right keywords... :)
At least this gives me a strong direction, thanks for posting this!
