Juddering / Shuddering vibration differential

Juddering / Shuddering vibration differential
Hi
Audi TT MK1 3.2 4WD petrol 2003 144,000miles
The traction-control warning light came on, take to a garage, said it was a clock spring / SLIP RING / 1J0959654M
Changed the clock spring / SLIP RING / 1J0959654M, light still on.
A few weeks later there is a Juddering / Shuddering when you pull off, and shuddering/vibration from the back end. Which is Worse when going around corners uphill, at low speed, or on uneven roads, you can power through it and at high speed, it seems ok.
Anyone else had this?
Could it be -
Haldex ECU (limited slip differential control unit)
differential
Haldex valve
Love driving this car, but on a limited budget so any help would be welcome
Thanks

Sounds like the rear differential is staying locked.
Have to determine if it is due to a mechanical bind, electrical or pneumatic issue. Standard troubleshooting techniques apply. Follow guided fault finding steps in the service manual. Also see if anything comes up in a VCDS scan. Not a generic scan tool as the fault here would not fall under SAE generic codes.

My prediction is a failed Haldex controller. It is a fairly common problem. A scan with VCDS should reveal it. If it is worse when turning sharply at low speeds this is consistent with this failure. The Haldex stays engaged when it shouldn’t and since there is no center differential the tires have to slip in order to compensate for the different radius of the front axle and rear axle paths.

Will it damage the Haldex unit if the controller is a problem and you remove the fuse and drive the car?
And does the VCDS Lite give the information necessary to diagnose this problem?
Thnak you,

Does anyone know that if you remove the fuse for the haldex and it is a controller problem, will the shuddering stop? (Car stored and easier to ask)

Good luck. They are not simple cars and they are getting old.

I looked in the service records and there is no mention of the HALDEX filter being changed. If there were low pressure, would the VCDS show a fault code? Changing fluid and filter this weekend. Also if there were low pressure, wouldn't that mean the haldex would just not engage?

broomellw. Sharing what you asked me via private message for others input. You mentioned that you pulled the Haldex fuse and the car will not move and makes a rubbing noise. Since the front wheels are ALWAYS engaged in our cars this told me this.
”bingo! Sounds like you have a FRONT axle stripped. The Haldex Drive is engaging and making the car move. Jack up one side at a time and with the car in gear, try to rotate the front wheel. Neither should be able to turn. The one that does has stripped splines in the half shaft. I’ve seen this reported twice over the years. Last time the leader of the TT East drive on his way home from our event. “
