Diagnostic help?

2001 Audi TT has begun popping up the ABS warning light. It doesn't remain lit long, sometimes next off/on cycle is enough. Here's the log, a sensor near the right front inner fender?

Thanks for any experience with this one.

Hi, My 2001 Coupe did that several years ago. If I remember correctly the longitudinal sensor is behind the glove box and accessible by the dash panel end cap. The other one ( lateral) is in the dash panel near the steering column. It’s about a $250 part. It does require vag com to calibrate the signal after replacement. It does reset after each stop start cycle and codes are not visible wants the engine has been turned off and restarted. Lots of info online if you search Audi TT acceleration sensors. Good luck!
