hi guys
my cup has started to make a whining noise from under the bonnet sounds like a charger lol. i have had the bonnet up and and revved the car but cant really here anything. its just when i have the window down i can here it. it dosent just happen going round corners. but is always there and is really annoying. i had the cambelt done around 4k ago.
any ideas
cheers

Mine did this, it turned out to be a fecked alternator.

how much is one of these. is there a way of diagnosing this for certain or is it just a process of elimination

Normal whining noise is the lower aux belt idler but as yours is a cup, it wont have one.

What was replaced on your cambelt change? Full kit?
