If you have a nice dry and well lit garage, with decent coffee available, I would be happy to pop over and supervise. 

Thanks my friend, but I’m more than capable, and if the service kit arrives tomorrow morning, I will be on it

@ATM struggling to find the diff fill plug seen something that looked like a fill plug but it was about 25 mm long , looked more like a detention pin, left hand side at the top near the gear box mount?

Isn't that the one that develops a leak and the only solution (according to Stuttgart) is an £8k gearbox...

I'd need a pic.

Are you following a guide or instructions from somewhere?

From memory there are 2 drains for gear oil. I can't remember if I ever did both. I only did this once.

I only remember 1 fill plug for gear oil. It's a hex type Allen key quite big like 8mm. Plug itself is like 20mm wide - maybe a tad less. I did the fill, drove the car a bit then checked it was still full by squirtng a bit more in.

I regularly filled clutch fluid as this was leaking. This was accessed from passenger side. Similar size plug if not identical. I used to raise the car a bit via rear side jack point and remove rear wheel then access it through the arch.

Hopefully you have not drained it yet because best practice is locate the filler first and check it can be removed before you drain?

Drained out 4lt of clutch fluid and 2.2 lt of diff oil, sound about right ?

No reason to disagree. I assume the car was working fine beforehand. I think from the factory they don't fill till it dribbles out. Some people think this is over filling. But gearboxes have always had a filler at just the right level so I go off that.

 

Did it look dirty or clean?

 

The first shift from 1st to 2nd on a cold start felt much better in mine with fresh clutch fluid. Recently its started feeling jerky so I might renew it. I'm anxious the gearbox repair shop may have used cheap fluids.

 

I use Millers DCT DSG stuff for clutch and their 75 90 for gear.

 

My car would start throwing up errors or warnings when the clutch fluid got low. I'd then add maybe just over a litre of fresh and it would then be fine again. I must have done this about 10 times.

 

So I was topping it up lots. I think I only drained it once and with the leak no idea how much came out and its not going to help you even if I did.

Not overly dirty , nothing on the sump pan magnets , can only be a tick regarding preventative maintenance?!

Did you change the sump and filter?

Late to the conversation - but found this re capacities 

The Porsche Doppelkupplung (PDK) has two separate oil supplies and oil types. Pentosin FFL-3 hydraulic oil is used for clutch actuation and gearshifts. The filling capacity is 5.6 qts (5.3 liters).

The gear wheel oil and differential chambers are filled with 3.0 qts (2.9 liters) of Mobilube PTX, SAE 75W-90. The change interval for both oil types is 120,000 miles (180,000 km).

I think that’s depending if you can totally drain or measurement if it’s brand new in the box

Yeah - dry fill will always be more....

But, I did think that on the fluid side you are somewhere near 25% short by those numbers - that seems like a lot left behind to me but just thinking out loud really - it's all learning.

That way came out  can’t do nothing wrong by re applying the same amount give or take

Got another 150 m/l out by lifting the car a bit higher on the front this morning 

I saw something on Internet about fashioning a sort of bent tube to suck out more. If you're really bothered about the last little bit then just do the whole thing again after a few weeks so it's had chance to mix. If you have say 5% of old remaining then after the 2nd time round you will have 0.25% of the old stuff in there.

Not that an*l enough for that the fact 90% of it will be new is better than 90% not new!!

I'd be more concerned about the clutch fluid. Gears are just gears. The clutch is pure trickery.

Correct parts arrived today , got back from work and completed the job, filled up till dribbling added 4 lt , ran it up to temperature, rechecked not dribbling added approximately 250 m/l more till it dribbled again, same with diff oil , that did not require anymore than 2.3 lt I put it. All built back up and test driven does appear smoother but could be placebo effect

Also because D911 cocked the order up , sent me 10 lt of clutch fluid  and a gasket set! £270 no oil pan or diff oil

On return of 5lt of clutch fluid and gasket set, they have sent me the aluminium motor sport oil pan and 3 lt of diff oil , they have organised the return of wrong items and no additional cost to me !!

Any reason you didn’t get them from Porsch Wilmslow? I thought the OEM only stuff was cheaper there?
