There may be a weakness in the cambelt tensioners of the D5 engine that the service schedule doesn't address. My engine is now completely dead and requires replacement at almost $15,000 ( UK prices ) which makes the vehicle fit for scrap.
Please don't fall into the trap that I did by delaying the Cambelt change to the scheduled 96000 miles. I followed all the rules by having my car serviced on time and at Main Volvo Dealers. My mileage - 75000
