That looks like a massive improvement compared to the first scan:

The electrical errors are gone now that you have things prepped for the steel suspension and they changed to "Implausible Signal". I believe you are on the right path and that should be resolved as soon as the new sensors are installed.

Scans from today while I wait for the sensors to arrive.
Do these look like it currently doesnt see the installed sensors?
Just trying to understand the scans..
Thanks!

Hi Folks,
I received my 8J0 941 273 H height sensor for the front, but it actually came as a rev D instead of a rev H.
So, that didn't work. Looking closer at it the 8J0 941 273 H is the part number for the entire sensor assembly ( Sensor, mounts, linkage) not just the sensor itself. The rev D assembly I got has a 4f0 907 503 sensor in it.
That happens to be the exact same sensor that I removed form the rear of the car.
So before I order another 8J0 941 273 H and get the wrong one delivered , does anyone out there have a 8J0 941 273 H that could look at the actual sensor number and let me know what that one should be ? That way I can verify it before purchasing and going through the return hassles if its not right?

Thanks All!

Update:
I was able to determine that the 8J0 941 273 H assembly uses the 1T0 907 503B sensor in it.
I was able to order both the 1K0 941 273 M for the rear and 1T0 907 503B sensor only for the front. ( Both aftermarket )
After installing both and clearing the codes, doing the headlight range adaptation all errors are gone!
So in short to do the Mag ride delete for my car:

Follow all the documented procedures above, reroute the wires from the LEFT front and rear sensors from the mag ride module located under the passenger seat, to the headlight range control module located behind the radio.
I had to buy pins to fit in the range control module connector, see picture below. ( either item will fit they are just for two different wire sizes)
Then replace the ride height sensors with the ones listed above and reset the errors then do the adaptation ( with VCDS)
at this point mine all worked! no errors.

Thanks All for the help!


Pins needed from Digikey:

5-963715-1
TE Connectivity AMP Connectors
MQS REC CONT
