Complicated Dmf/clutch change
Having recently completed a clutch replacement on a 2010 Audi A6, I was expecting the same job on an A5 to be similar. My mistake!
The clutch on the A5 is very different. The driveshafts are so far forwards of the inline gearbox that one of them actually passes through a gap in the dual mass flywheel (DMF). The clutch unit is bolted to the DMF and the whole assembly needs to be removed with the gearbox after detaching it from the driveplate – this is similar to unbolting a torque convertor on an automatic, but with the added weight. Once unbolted, the six-speed gearbox, along with the DMF and clutch, needs to be lowered out of the vehicle. Once out, the nearside driveshaft which runs through the bellhousing can be removed, allowing the clutch and flywheel assembly to slide off the input shaft.
The new DMF and clutch assembly needs to be built up before refitting onto the gearbox. Once in place, the driveshaft can be slid back into position. The entire job takes 7.5 hours and, including of a new DMF and clutch, has a total cost of around £1500.
One of the driveshafts slides through the specially designed DMF unit.
