I noticed this problem on my old Mk3 TDI....im also noticing it on my new mk3.
Whenever it rains, or has been raining my steering wheel doesnt work properley few a bout 10 - 20 seconds.
I notice it when going round sharp corners or islands, it seems to jam. Quite dangerous in my opinion, but only for a split second, then continues to turn as normal.
Very annoying, no garage knows whats wrong, any similar experiences?
Both cars have been lowered.....never happened before they was lowered.
