Hi Folks, Just had word from the shop today that the engine noise has been fixed.

Before I took it to the shop, I recorded the engine noise onto CD so the tech's could listen to it. Also I hoked up an engine vibration analyser and printed out a GOOD start and a BAD (after standing for 4 days) start vibration signatures.

I gave alll this stuff to the dealer who were very impressed.

They are 99.9% sure that the fault was caused by the Cam Belt Tensioner (too slack).

Hope this is helpfull to others with the same symptoms. If anyone would like a copy of the .wav file and waveforms please let me know(deonrowley@compuserve.com)

Best to get yours fixed under warenty too if you can as the labour costs may be high.
