Facing the same servo restricted issue, but some strange behaviour after replacing the sensor. Initial fault codes: UO41600: Invalid Data Received From Vehicle Dynamics Control Module Status: Test failed, Test failed (current drive cycle) U041500: Invalid Data Received From, Anti-Lock Brake System Control Module Status: Test failed, Test failed (current drive cycle) Replaced with an Amazon sensor. Immediately restarted and fault codes were: UO41600 + U041500 as above. Time corresponds to after replacing. CO54B00: Vacuum Sensor "A" Circuit Low Vacuum_Sensor_1:_Line_is_low Time corresponds to after replacing. I then cleared the codes (with Car Scanner app, not VCDS) and now have this: UO41600 + U041500 as above. 264448 Status: Test failed, Test failed (current drive cycle) From module 03 ABS control unit. (264448 preceded the CO54B00 code above, but this doesn't have any more details). Would appreciate any suggestions as to my next options. At the moment I am considering: Complete a normal drive cycle (although worried about bricking the ABS). Try clearing the codes with VCDS (although previous posts here suggest clearing codes shouldn't even be necessary). Try refitting the sensor, checking wires and the o-ring. Get another sensor (likely not aftermarket from Amazon).
