Title: Audi TT Traction Control Issues Post by: Cadensdad14 on September 04, 2021, 03:54:57 PM I'm rally racing a TT Quattro, but having an issue with low grip situations and traction control. Whenever the Haldex engages, especially on WOT uphill sections im having throttle cuts to the point where I might as well have completely lifted. In these situations I really want the car to dig for grip.
Im on my way home to dig through the FR sections GGCASR and the one for ESP. What other modules might be related to the traction control and haldex?

Hope this helps Title: Re: Audi TT Traction Control Issues Post by: Cadensdad14 on September 05, 2021, 05:43:35 PM I got those off the s4wiki page last night after i did more research. Should have started there. My question now is that it describes CWMSRCAN as being 0x02 and making it 0x06 or 0x07, but my starting value was 0x86. Considering its a 2000 model it may not have come with ESP and the 0x06 part may be right, but I can't figure out what the 0x80 bit is for. Could that be for the Haldex signal?

Log instead of guessing. Don't start threads like this without logs showing exactly what it is doing. It's a waste of everyone's time. Intervention can be logged with ME7Logger. |
