Hi,

I feel for you as, whatever the outcome, you are likely looking at an expensive job to get your XC90 back on the road. This is the first major failure of the 4 cylinder D5 engine I've heard of, presumably there will be damage to valves and possibly pistons which may result in a new engine? no doubt other forum users will comment.

The investigation has got to centre around the replacement of the cam belt by your local independent Volvo garage, as you say possibly faulty parts or poor workmanship. The only suggestion I can give is that on the old five cylinder D5 engine it has been known for the auxilliary belt tensioner to fail, causing that belt to shred and take the cam belt with it. I don't know whether the newer D5 has a similar layout but that may be a starting point. Presumably the auxilliary belt and idler and tensioner was replaced in October?

Let's hope that you come to a satisfactory solution, please keep us informed.
