    MQB (Mk7 Golf) Steering Angle Sensor (G85) Calibration in 44 - Steering Assist

    We've had some customer inquiries about this so I was able to induce a fault in my 2015 GTI in 44-Steering Assist and was able to clear it using the following steps.

    First, here is the fault in question:



    So first with the engine running, I went into Adv Meas Values and made sure that the steering wheel was pointed straight and the front wheels were pointed straight, close enough:



    Edit to show identifier for use use with recent versions of VCDS:

    [IDE04448-IDE00924],Steering angle sensor: angle - Steering angle


    Next, I went into Security Access -16 and entered the code that shows up in the little helper balloon and it was accepted.

    Next, I went into Basic Settings - 04 and chose "Steering angle sensor" and clicked [Go!]



    Edit to show identifier for recent versions of VCDS:

    [MAS00815] Steering angle sensor

    Here's the weird part, it showed "Running" but never changed from that. I left it in this mode for 60 seconds then clicked on [Stop] and [Done, Go Back] and [Close Controller, Go Back].

    Next, I cycled the ignition off and back on again. At this point, the TPMS, steering wheel, and ESP lights were still lit up on the dash but a brief drive through a parking lot made them all go away.

    Excellent, C?ID=211236 confirmed the procedure worked for his replaced steering rack. But I typed too soon, he has some end stop faults. I will update as he tests more.

    I have the end stop faults and was wondering if you ever figured out what the solution is on the MkVII Golf.

    Start the car up, make sure that wheels and steering wheel is perfectly straight, go to 44, login, select basic setting of steering angle, then when it's saying "running" slowly turn the steering wheel all way to left, then slowly to the right, turn it back to straight. It should now show "Basic setting OK". Your G85 is now calibrated properly and end-stops faults should go away, if not do the same procedure but choose "learning end stops" in basic setting.

    Thank you, I tried the first step under "steering angle", but then it made me have 4 new faults and my dash lit up with TPMS, ESC, Steering warning lamps that did not clear driving around the parking lot. I lost the active return function, steering felt really weird. I pulled back into parking lot, did the steering angle sensor reset again (no turning of the wheel) and that cleared the dash warning lights that were on and put my steering back to feeling normal, but it didn't clear the end stop fault... it came back. Just to confirm, when you say "learning end stops", you mean "software end stops"? Also, the status never changed from "running" to "Basic Setting Ok". I SINCERELY APPRECIATE YOUR HELP!

    Yes I meaned the "software end stops". Also when you will be turning the wheel, hold the wheel until dash beeps or for about 2 sec. in both left and right end positions.

    We did some more testing on this in October and I don't think we've had a chance to detail a procedure yet but I will see what I can find.

    I believe automech has more experience than we do on the subject (we failed to truly break Andy's 2015 GTI) but these are notes from my most recent phone ticket on a crashed 2015 A3:

    037224 - Steering angle sensor mechanical failure in 03 - ABS.

    SA code 19249 = Adaptation/Basic Setting Enabling was needed for each basic setting attempt but you can only login once per diagnostic session (or it will error).

    The somewhat successful run involved #44 > Adv MVB

    [*IDE04448-IDE00924*],067,Steering angle sensor; angle - Steering angle,LINEAR,¡ã

    to get it centered but he also checked some with descriptions like

    [*IDE02216-IDE05795*],019,Steering angle sensor; basic setting - End basic setting,TT,

    Which reported Not permitted. We selected SA > BS

    [*IDE06133-*],4,Software end-stop reset,HEXBYTES,

    which finished correctly and had to exit entirely because the next SA is refused. After another reconnect to 44 we got BS

    [*MAS00815-*],5,Steering angle sensor,HEXBYTES,

    to say Running and used [Stop] but he still had the ABS fault after a engine restart and lock-to-lock.

    He will test drive it at this point and call back if needed. 5Q0-909-144.lbl and something like EV_SteerAssisMQB_AU37.TOD per our last internal DS
    ST?ID=71374

    That may or may not help here but he didn't call or e-mail back so I believe the test drive sorted it. It was unknown if the rack was original or replaced in this case.
