Hi folks,

Im after some desperate urgent help please.

Our Astra J 2.0 CDTI 2011, has today developed, what I can only describe as, a distressed squeel/groan from the right hand side of the engine. 

It sounds like its coming from around the alternator/cambelt area. 
In addition, im also hearing a faint distant metallic rattle.

Can you please help? 

Its intermittent but in the last few hours and after about a 10 mile drive its gradually gotten slightly louder and more frequent.
