thats not your control module!
your control modules working fine, its doing its job beautifully and diagnosing that theres a fault with the front sensor
if you start your car, full lock your steering aaaaaaaaall the way to the right, then in the left footwell if you can get behind the wheel you should be able to see the sensor, if all looks well, you can HOPE that its just the sensor giving up the ghost, chances are waters gotten into it, but worst case scenario its a wiring problem...
ideally if you can remove the left wheel and show us a picture of that area, the wheel sensor will be bolted to the left wishbone
if you can see that blatantly the sensors broken then theres your culprit, otherwise send me a PM and i've got a spare sensor sitting here that you can plug in and if that gets rid of the code, all you've got to do is unbolt the sensor assembly, undo the two screws which are holding the current broken sensor in the sensor arms, bolt in the new one and your good to go!
the way that VW did the levelling system is really quite good compared to some of the other offerings by OEMS and the sensors that are used (made by hella are fairly reliable however they do go from time to time)
let me know how you go
