Is there an expected lifespan (mileage) for the Dual mass flywheels. I realise highly dependant on useage. Does it pay to change them out if doing a clutch change.

It depends on driving style and environment. If wet clutch DSG and often drive in city traffic with lots of stops and traffic halts. Well, they tend to have a short lifespan, from 60 000 miles to 100 000 miles. Combine that style of driving with trailer (heavy towing) it is a certain recipe for DMF failure. use manual gearing in those situations.

If manual, they will last much longer. 

 

Never ever just replace clutchdisk and pressureplate without DMF. When all things are down, do the whole clutch assembly with DMF. I guess most reasonable car mechanics will agree with me on this one.
