This is the direct email address for the MD of VW UK: robert.hazelwood@volkswagen.co.uk
If you want a phone no, then this one: 08443754625 will get you through to the VW UK executive office where you will be able to speak to someone important 
Anyone able to confirm is this is still the current MD, and his email address?
Also has anyone had a repai to a sill paid for 100% recently? My dealer phoned yesterday to say the front arch will be covered in full, but only 50% of the sill.
I want to contact VW with regards to why the rear arches are no longer covered, and would mention the other 50% of the sill too.
