Default 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.

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)
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,

Thnak you,
Sorry but I don’t know about the generic cable and VCDS lite. I’ve had a Ross Tech sourced HexCAN cable with matching software since forever. You might ask your questions over on QuattroWorld Mk1TT. Might ask on VW Vortex too. There are still some of the long time owners there. I would think that pulling the fuse might stop the binding but not be a complete fix because it would make you fwd only. I have heard of guys doing this to dyno the cars on 2wd dynos. I have also read warnings from Haldex that pulling the fuse did not totally disengage the clutches and that 2wd dynos should not be used. So— not sure.
Good luck. They are not simple cars and they are getting old.

I have this same problem and is exactly as you described. I purchased a VCDS cable and software. Here is the log. it appears to me the haldex has no faults. Is it then most likely a mechanical problem?
Thank you.

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. “

I checked the front axles lifting one off the ground seeing if i could turn the tire / wheel and other than a minimal play in the CV joints, I could not rotate the wheels that was off the ground, Checked again to see if I was dreaming and no the car does not moves of budge if the haldex is disabled by fuse 31 on the haldex. Help.
