It isnt a very satisfactory approach other than it gives the impression service costs are lower than actually required. It also smacks of poor engineering design and location of ancillaries such as aircon and power steering pumps if the drive belt can cause such mayhem if it fails.

The need for it to be replaced is because volvo stipulate that it must be changed every 54000 miles on that service ..and at the other services it's tension must be checked and adjusted if required .
You are not looking at the
volvo service specification literature it seems ...
The Aux belt and Tensioner on yours is unique to the D6 , it runs the Starter/generator and is considerably stronger than on the other models ..with an equally stronger tensioner .
Tension is set via a frequency reading tool , ie, it measures the frequency the belt vibrates at when plucked ... it is crucial it is within tolerance , a dealer job if you cherish your engine ..
