Sorry, I posted the wrong info before about the cost. They carried out a 20,000 miles service (which as you rightly say is everything from the 1st service plus the pollen filter). They also did a brake fluid change as it is due after two years apparently. They charged me 130.20 + VAT for the labour and 20.25 + VAT for the parts, n.b. this doesn't include the oil as I provided it. that makes a total inc VAT of £176.78. And free of charge came that lovely, awre inspiring, residual improving, & pocket emptying VW stamp :0)
