VW Macclesfield rang me about an hour ago with their 'special deal' prices of:
£299 for belt, pulley & tensioner
or
£399 for belt, pulley, tensioner & water pump
All this includes parts, labour and VAT, which seems pretty reasonable.
They said that the recommended time to change the belt is 4 years / 40k miles. Does this sound about right?
Mine's an '06 with 51k on the clock.
