On first inspection of our Audi A5 we found some excessive play in the front drive flange cup. We initially suspected bearing wear but after removing the gearbox we found the problem to be something else...

Whilst the gearbox was out and the fact it wasn't a 2 minute job to do so, we also decided to replace the Flywheel for a new unit. Another issue that we addressed at the same time was oil starvation causing clutch slip. Under hard acceleration oil is pushed to the back of the gearbox and away from the oil pick up. This in turn reduced the oil pressure providing the clamping force on the clutches and can cause momentary clutch slip.
The Catch Can kit we fitted allowed us to over fill the gearbox eliminating the pressure drop. Increasing the oil level will also help slow down the rising oil temperatures due to increased volume.
