ABS & ESP issues
The car is in the shop right now for this, but thought I'd ask around and see if anyone has seen this...
The ABS light has been on solid now for about 500 miles, coincidentally coinciding with rolling over 100,000 miles, a set of new tires, and a change from PSS9's to the eibach/bilstein combo. VAGCOM says to check the left front speed sensor. The code can't be cleared, and it causes a seperate code to pop up in the esp module saying to look at the abs one. At least they talk
Aside from the ABS light being on, when I start the car, for about the first 100 feet under acceleration the car hesitates and lunges repeatedly, then the ESP light kicks on and it drives fine. The guy at the shop said it was probably the ABS controller, and that he's seen several cars (didn't say TT's) with this issue lately. Any thoughts on this?

Could be the wheel speed sensor, hope that it is, as that is easy and cheap to replace. ABS modules
are $$$... I could see with a new suspension that maybe the wheel speed sensor could get knocked/damaged. Here it is (at the tip of the screwdriver):
