Well, I've now joined this particular club. Exactly same symptoms as above, first noticed the whooshing air leak sound, slight smell of fumes inside. I'm mainly motorway miles, but am always noticing regens when stopping at home these days, after ten or so miles of town driving. On hold for VW service now. 2018 2WD 204 PV.
What mileage are you on?
I think I’ll check mine tomorrow to see if it’s the old type or the new modified one.
