Abs code 00283 front left sensor short to plus

Post by allroadadi » Sat May 03, 2025 4:25 am

Hi! I’m trying to troubleshoot this error on my rs6.
So far I’ve tested the resistance and it’s 1.640 k ohms, also it reads 4.7V on the cable coming from inside the car (disconnected the abs sensor and hooked up VCDS with module open).
Cleared the code and it immediately comes back.
Took off the sensor and cleaned it really well. No dice.
Took off the abs module connector and a few prongs were corroded-ish (green, cleaned them, but now I’m wondering if it damaged the module.)
Do these cars have any relays that connect to the abs module? I couldn’t figure out from the service manual as it is not rs6 specific (abs is general for all years and models in C5 which is ridiculous). I took the knee bolster off trying to see if there are any relays for abs and couldn’t figure out.

Swap the left sensor with the right. If the problem is still showing up on the left it's probably your ABS module that is knackered. You'll need to get it repaired if so. This is the most likely explanation in my opinion.

There are no relays between the ABS module and the wheel sensors.
