Transmission Oil Changes help

[TonyMalopney]

Greetings T6 Owners,
We recently shipped our T6 to Brisbane a couple of months ago to do a lap of the country and I'm thinking about having the transmission fluids changed as the odo reached the 100K km mark.
We're currently in Darwin and the VW dealer is struggling to identify what the Haldex oil is and does not know how much front and rear axle/transmission oil is required.
I tried having a look through earlier posts and then downloaded the manuals from the T6 Forums site but I have not been able to find out the following info. Could any of you smart folks help please?

2016 T6 4Motion, 6 speed Manual, High roof, with CFCA Engine

- Front Axle / transmission Oil Spec: G052145S2 - Axle Oil (1 litre) - Differential & Gear Oil 75W-90
- Front Axle / transmission Oil Volume: ???
- Rear Axle Oil Spec : G052145S2 - Axle Oil (1 litre) - Differential & Gear Oil 75W-90
- Rear Axle Oil Volume : ???

- Haldex Coupling Oil Spec: ???
- Haldex Coupling Oil volume: ???

Thanks in advance
Churs
Tony

Welcome, and hope you are enjoying your circumnavigation of Australia.


Regarding the Haldex....
According to these experts IMO you have a gen 5 Haldex

They spec the correct oil, volume (looks like 850ml) required etc, as well as how to visually check for sure which generation of Haldex you have.

You will probably want the O rings as well and make sure they clean the gunk out of the filter screen (it will certainly be pretty clogged up)

I would carefully read up on haldex oil changes. There are two drain plugs close together (from what I’ve read) and mechanics get mixed up on what to drain and where to re-fill. This often leads to part of the diff / haldex unit running dry.

There have been lots of catastrophic failures about 1000 miles after a haldex oil change!

Edited to say this is across VW group vehicles not just Transporters.

I’ve just done mine, super easy job to do, just make sure you get the pump out to clean the muck off the filter / strainer

The hardest part of the job it getting the electrical connector for the pump off the back of the control unit.

See photos
This was done at 118,000mi, I don’t believe it has been done before.

Hey Thanks for the feedback,
Just about to order the oils in but need to know how much of each is needed for the front and rear diff. Can someone please help?

Specs for the 6 speed manual gearbox MQ500 which I assume is in your van. Note spec is slightly different to the spec (G 052 527 S2) you had above.

VAG manual gearboxes: MQ500.

Specifications​

Production years	2003 – 2022
Type	manual transmission
Number of gears	6
Type of drive	front / all wheel
Engine volume, l	up to 2.5
Torque output, Nm	up to 500
Recommended oil	G 052 527 A2
Oil capacity, liter	2.3
Replacing the oil	every 80,000 km
Replacing the filter	every 80,000 km
Gearbox lifespan, km	~300 000

I will see what I can find for the front and rear diffs, but probably around 1 litre in each (I haven't chenged those fluids yet)

Thanks for the info (nice clear table of details)
Wish VW Manuals were as clear

Thanks for the heads up, I would like to read up on this topic but best I can find is good old YouTube videos

I'll have a chat with the mechanic to make sure he's aware of this and order the o rings just in case.
Thanks for your response

Thread 'T6 4Motion differential catastrophic failure'

26 Sep 2022

Hello,

I'm in trouble with my T6 and as far as I can tell it's a fairly unique problem. Any advice or insight would be greatly appreciated.

~4 Months ago I bought a lovely 2018 T6 Camper (converted), bi-turbo, 7 Speed DSG and 4Motion with 70k miles / 115km on the clock. I got it serviced as the timing belt was due, as well as new fluid in the DSG box and diff. This was at a mainline dealer here in Dublin so it wasn't a cheap service but I intended to keep the van for a long time. They said the flywheel was starting to go so I took it back to where I bought it and they kindly fitted a new...

I’ve just completed my DSG oil, Haldex oil, and engine oil service, the van has done 118,000mi
The front bevel drive and the rear differential appear to be the only fluids left to replace?

I’ll be watching this, I know for sure they haven’t been changed!
