If you get the stalk from VW it's only £96.22 inc VAT.
I don't know why the aftermarket ones are more(?)
If you talk to VW, then it is not as simple as having LX windows (or DIS).
According to them you need to confirm if the supply controller under the DS dash is up to the job.
This is part number JH0937049
If the # ends a AA, AD, or AE then you're OK.A:
If it ends: AB or AC then you need a new unit which is £360LOL:
My number ends with 'K'. VW can't tell me if it is OK or not, but will charge me £42 for 60 seconds work connecting a laptop, to tell me if it's OK for me to buy something from them
That's customer service if I ever heard of it!!!!
