Steve. We have all accepted that the clutch needs to be replaced, but is that true? Has there been any investigation of the problem, which I assume is slippage? If it is cable operated has it been adjusted? If hydraulic, have the seals been changed and the air bled out? Maybe you have looked into all those options, I only mention them as a way of getting the best out of the clutch at a minimal cost.

Just thought I would update my post as no one really had the answer to my question. I did the gearbox oil change today on my 2016 Q7 4M on 80k miles. While it was messy and fiddly I did it on my drive without too many issues in 3 hours. Anyone thinking of doing this here are some notes: The gearbox is a ZF 8 Speed and you need to order the ZF kit which contains 7 Litres of oil, the sump tray (which contains the oil filter and magnets), fill plug and bolts. I ordered mine from Autodoc for £189 and it arrived in a few days. You'll need some diagnostic equipment so you can read the gearbox oil temperature. Lift car on ramps/axle stands so it remains level Remove underbody shield Undo fill plug (10mm Allen Key) Remove Drain plug and drain oil Support the rear of the geabox Remove geabox rear support bracket Remove pan cover screws Lubricate new sealing ring Clean the gearbox mating surface Install new pan using cris cross method Reinstall gearbox rear mount Fill gearbox until oil flows back out Start the engine Maintain 2000rpm for 20 seconds to fill the torque converter Change manually into reverse and hold for 10 seconds then into first and hold for 10 seconds Check transmission fluid temperate is between 30c and 40c Now top up fluid with engine running until it fluid runs out again When fluid coming out is down to a few drops reinstall fill plug and tighten to 35Nm Reinstall under body tray I hope this helps someone.
