Just to help others in the same situation, here's my history:
Skoda Fabia Monte Carlo 1.6TDI September 2013 plate with Continental SportContact 2 205/40Z R17 tyres
From new it pulled to the left slightly and was only noticeable on motorways, etc. It didn't bother me that much as I tend to stick to the twisties
During first service, I got them to check the tracking - no difference
Once the fronts were worn, I replaced them with Dunlop Sport Maxx - couldn't really tell the difference
Recently, I've been commuting along the motorway and it's been driving me nuts
The other week I complained again to my local dealer, highlighting this thread and others, while it was in for its 3 year service (27,000 miles). They checked the tracking, made a minor tweak and adjusted the steering wheel position - no difference but now the steering wheel was offset so in essence it was worse (cosmetic).
I complained and took it in again today only this time they gave it the full tracking treatment and swapped the front for the rear i.e. Continentals back on the front and Dunlops on the rear
The result? Perfection! I can't say which was the culprit but I suspect it was a combination of both the tracking and the tyres as it pulled when the original Conti's where on the front and it has always felt vague when pushed in the corners - now it feels planted, well, as planted as a stock car can be.
The only downside is that I now have to actually apply force to the steering wheel to go round left hand bends :-(
