Hi Ian, thanks for your reply.
I've bought parts from Summit Garage and have been impressed with their service.
Regarding the timing belt changes though, were you invoiced for any tensioner and/or idler pulleys at the time?
I noticed a rattle at 67,000 miles only after starting from cold. My ancillary belt had a cut across all five ribs. You can check this easily after removing the OSF wheel arch liner. But the major advance in smoothness followed later renewal of my ancillary belt tensioner and the two timing belt pulleys.
