Check the alternator output, it may be over-charging.

Hi, its currently on 60k with good history, i have no noises and all flexy pipes seem to be in good order.

this seems to be a very common problem with the pug 307, thanks for your reply i'll have another look over it tonight, fingers crossed.

Mileage? Service history? Any hissing noises from under the bonnet near the top of the engine, e.g. cracking or leaking black plastic flexy pipe? They get brittle and crack with age and could cause those sort of symptoms.

If so, replace the flexy pipe with a brand new one. Not expensive.
