Just to add that I too have just found a broken offside rear suspension spring on my 2015 Audi Q7 at 87k miles. Was replacing rear brakes when I saw it. 

Anyone had a go at changing these themselves? Struggling to find the part online and the Workshop manual mentions special tools required which might just be a fancy spring compressor.

Thanks for the quick reply. Mine is on 70k and occasionally changes are a bit jerky sometimes in 4th to 5th and like you I’m planning on keeping the car and running it to high miles. 
 

just trying to evaluate whether it’s worth doing. 

Mine is jerky in the lower gears but only when cold. It hunts between 1 and 2 so I tend to put it in sports mode for the first few miles which solves it. Never had any issues with the higher gears.

Thanks for this procedure!  Very helpful.

 

Sorry to dig up an old thread on my first post!  I'm considering changing the gearbox oil on my Q7, did you notice any improvements with yours once you did it and what condition was the oil in?

Gear change is still a bit hit and miss when cold. The old oil didn't smell or look burnt. The car was on about 75k miles when I changed it.

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.

I completely forgot posting this question 😀 Thanks for the reply Steve, that link doesn't mention any schedule for Gearbox oil which would indicate Audi thinks Gearbox oil lasts the life of the car. 

Hi, my first post! I'm a new Audi Q7 owner having recently purchased a 2016 S-Line. It is a great car and pulls our big caravan like a train. The car is on 80k miles and I have just done an Oil and filter change but wondered if the gearbox oil needs changing too? Gear change is smooth but when cold it can be a little bit hit and miss where it changes up and then down quickly. Having never owned an Audi before (or an Auto Gearbox) I'm not sure if this is normal or a sign that the gearbox oil should be changed.

I've checked through the services records and the standard stuff has been done at the required intervals but no mention of gearbox oil change.

Does anyone know when this should be done and the procedure as I'll be doing it myself?
