ABS Issue - 01200 Valve Supply Voltage

B6/7 S4/RS4
#1

Hey all, I want to tap into the brain trust that is on here to see if anyone has run into this issue and what the resolution was. A little while ago I got the dreaded 3 beeps on start up and my ABS, ESP, and Brake lights stay on (brake light flashes). A VAG COM scan shows the following error:

            Address 03: ABS Brakes       Labels: 8E0-614-517.lbl

Control Module Part Number: 8E0 614 517 Q
Component and/or Version: ABS/ESP allrad 3033
Software Coding: 04595
Work Shop Code: WSC 06435
VCID: 3668CB6612E4D3A8CB0
1 Fault Found:

01200 - ABS Valves Supply Voltage
35-00 - -

I checked all the fuses, checked the voltage at different points including the wiring harness (fuses and voltage were all good), and came to the conclusion that the issue is the control module. I sent the control module out to Module Masters for repair. I recently put it back in and am still getting the same error. Before I get back to Module Masters, I wanted to see if anyone had any thoughts on other areas that I can check.

TIA

Try doing a voltage drop test across the fuse with the engine running. I had a few fuses partially break but still work-ish while causing issues. Looked ok by eye and with a test light.

Thanks, I will give that a try.

Dis modual masters tell you whatthwy fixed. Itmight be that they didn’t fix fhe issue. I would call them and further thoughts.

They told me they repaired the unit, but did not get into specifics. I went through the fuses again and tested with the car running and the voltage isn’t dropping. I will be reaching out to MM.
