I am new here and recently purchase a 2008 Audi TT 3.2L Quattro Roadster with the S-Line Package. To date I have changed oil, replaced the radio, added a back-up camera, replaced a leaking headlight washer nozzle, and fixed a cracked lower faring. The other day I was driving and made a hard stop in traffic, the anti-slip dumbing light illuminated. Upon arriving home I checked the error codes and found under 03 - ABS Brakes the 01324 Control Module for All Wheel Drive (J492) was listed and under 22 - AWD the same code for the control module plus 02248 Valve for Controlling Clutch Angle (N373). I reset the error code and waiting for them to re-occur (confirm the errors). A couple days later I was stopping at a light and the same error occurred (confirmed with the scanner). After doing a little reading I decided to check the Control module and connectors. In an attempt to check the connectors for corrosion I removed the whole control box. Upon opening the box the Belleville Washer on the oil pressure and sender unit fell out. This seemed odd since the oil pressure and sender unit was still engaged with the Haldex unit. I reviewed some schematics online and did some fit up before determining the proper assembly. I then re-assembled the unit, cleared the error codes, and took the car for a drive.; at the end of the drive the error popped up as I stopped in my driveway.

Does anyone have any ideas on anything else to check or look at specific to this error? I did not check the fittings for corrosion but the car is very clear with very little sign of corrosion. If I have to purchase a new control module and recommendations (I was looking at some upgrade units which apply more power to the rear wheels).

I made one observation and would be curious anyone's thoughts but I noticed the anti-slip light illuminates when the car is braking on a decline? Could it be low fluid?

I wanted to update this post, in case other run into this similar issue. The car I purchased had the rear rotors turned (instead of replaced) and within a couple months had warping issues. I found after replacing the rotors and bleeding the brakes that the issue disappeared.
