hi.
some time ago on the motorway something like 'stop oil pressure fault' appeared on my dashboard in my car. is it possible that weak camchain tensioner caused this? i have been in vw service, they want to replace oil pump (£490), but there is another fault - the camchain tensioner must be replaced as well (£440). By the way, replacing of tensioner in audi service cosrs £360. what is going on?
