Found the cause of my squeak!
A tiny bit of anti-slip on the belt and its sweet.
I can see the profile of the belt move about 1-2mm across the pulley. This syncs up with the squeak.
Tension is ok, alignment is fine, everything is located correctly and torqued up.
Any ideas? Suggestions how I may fix it.
Without a new belt our spraying belt spray on it every week.

Did you change water pump, tensioner?
How do you know the belt tension is spot on, could it be a tad tight?
-
waterpump,tensioner and idler pulley all replaced.
True, it could be a tad tight, but whats the best way of relieving this?
back off the tension using a bolt and reapply?
-
Yes you could give it a try.

On the longest run of the belt, grab it with your finger and thumb, how much can you twist it?
-
I see, can twist 90 degrees, same principle as 15mm deflection.
Tension is fine, noise comes back after a few days very faintly, a LITTLE bit of anti slip and the noise goes away.
Done 2500 Miles+ since cambelt change, so no problems there.
Doing my nut in.

I would say either the water pump, tensioner pulley bearings are a bit noisey, or you need to back the belt tension off ever so slightly.
Was the job done at a garage? parts from the dealer?

90 twist should be "reasonable" force, not finger breaking force.

Gen parts, DIY though.
Twist force is reasonable, nothing excessive.
-
Try backing off the tension very slightly.

Will do. Nice one

Oil too think perhaps?
I forgot to change my oil in one of my old cars in 2 years and the tensioner came loose which cause the timing chain to rattle inside the engine. no damage was done to the valve - but the oil was pretty think - I was sure this was the culprit.
