Interesting update for you lot...
So my car had it's 30,000 mile service yesterday and I asked the dealer (Lookers VW Preston) to look at the faulty bits of trim, and also the MDI cable which no longer works.
All pieces of trim and cable are not covered under warranty, and I would be required to pay for them. They said it was just wear and tear. I'm a little disappointed that they've only lasted 2 years before flaking off, and if I were to purchase the items it would cost me a little over £150.00 based on their quoted prices.
Not only that... I paid for a service pack when I bought the car and included in the pack is a brake fluid change included in the third service. When they sold this to me, they didn't say that it's only designed for customers who do 10,000 miles per year. I've done 15,000 miles per year, and therefore had the third service after only 2 years. The brake fluid change isn't due until 3 years old, so VW refused to carry it out. So when the fluid change needs doing after 3 years, I'll have to pay for it as I've had all 3 services under the plan (even though I've effectively paid for the brake fluid change to be carried out under the plan)...
Yet again I left a VW dealer feeling disappointed and seriously considering whether I'll ever have another.
