FYI for the few lucky individuals who may be experiencing the same issues

My March 03 MCS (JCW fitted September 03) has now been in for service 3 times for the same problem ... squeaking (for lack of a better description) on cold start, not warm start, only cold start, but something that has gotten progressively worse and VERY audible over time

First service, lubricated main belt, minor improvement, but squeak quickly returned

Second service, replaced the main belt, major improvement, squeak gone completely, but gradually returning after 4 months

Third service, root cause identified as a rusting main pulley

apparently doesn't happen very often, but got the impression if left untreated could result in some fairly serious potential failures

The third service is with a different dealership to the first two, so my perception of the first dealership has just dropped a peg or two.

Morale of the story ... if your car is squeaking, particularly at cold start, get it sorted pronto, sounds like things could get nasty if you don't

Hi M8,
There is an issue with belt noise at the moment (denso alternators) all the dealer has to do is loosen off the alternator whilst the belt is still connected and then retighten it. The alternators are miss aligned at the factory.

Did this help?

i have a similar problem, i had a top hose water leak a couple of months ago, spraying water over the left hand side of the engine bay. On cold start up i get a dry rattle for about a second, then the usual belt squeak noise.

Is there a possibility of the idler pulley/tensioner being rusty causing this noise, the belt was changed about 2months ago, so not that

Warranty out now so not a case of shipping it back to the stealer!!

Hi Guys,check out our GTT Twin Bearing Idler Pulley,GTT Tensioner Pulley,GTT Tensioner Stop & Drive Belt. Very quiet ,much longer belt life & protection for your tensioner assembly& crank pulley should it snap

Yes the alternator is not dowelled to the block (how naff is that!) and relies on the bolts only, in there 'very baggy clearance holes' for position/alignment.
Best Regards Roland Gt Tuning.

is this the basis of the problem then (the idler & tensioner pulley)???? do you think my water leak as described above could have had an effect on the pulley system??

Just changed the idler pulley and problem had gone, wahoo!!

I not sure how the pulley has not disintergrated, it was almost in pieces when i took it off!!
