Hi all,

I got my car serviced last oct/nov, full service and cambelt change. Just recently this noise bit like a ratlle/tap has started happening, sometimes its worse than others. But its always worse on startup and gets a bit quieter after running for a mile or so.

There are no warning lights on, car is 12 years old is200. 70000 miles.

i think you can identify it quite well at 32 seconds and past 2 mins, the noise is most identifable from inside the cabin which i failed to get but can get if it helps.

Cheers in advance for any help.
