Hi MrDo,
Oil change I don't know, do my own.
Clutch depends on whether the flywheel needs replacing too. The dual mass flywheel is an expensive item. I was quoted around £300 for a new clutch. However, my flywheel was fubar and needed replacing too. Total cost £940. I believe this is actually a decent price for the work and would expect to pay nearer £1500 from a dealer.
