Major service inc brake fluid change, all belts (cambelt, air-con and alt belts) for a VW Passat 1.8 petrol 99 V plate £635 at VW main dealer.

or £400 just to have all the belts changed.

Am going to ring my mechanic and see what he says, but would like your opinions.

Suggest you go to an independent as that service is nearly the value of the car

I paid £250 for a 40_000 service and brake fluid change at a Skoda dealer, and just paid £300 for a cambelt kit and waterpump change at an independant.
