These cold days I get a cold draught up from the steering column when turning left or right. There has to be a fair an]mount of steering wheel movement for this to happen. Anyone else? Any ideas?

Bulkhead grommet, gaiter, or whatever you have is torn?

I read about this on a Golf forum, i think the general consensus was that it would be a flap swinging open in the ventilation system.

Don't turrn left or right

I had same on my superb, never got to the bottom of it

Good luck !!
