Can you use OBDeleven to tell how often the VAQ has engaged?

To the OP, I have seen a service schedule that states diff oil change every three years.

Get it done at an independent specialist though, and ask them to clean all the gunk from the filter. VW will only change the fluid, not the filter. (If they even know what you are asking about).

Take a look on some of the golf R forums at the amount of crud they get in their Haldex filters.

That’s a very good suggestion, and you’ve helped me make my mind up.
Swapping the oil out, either myself or through VW, is probably pointless.
I’ll wait until about 30k then do just that at a good independent.

I would think usage/ mileage much more important than time. These oils don’t degrade over time.

Saw a post earlier on that said "Volkswagen state a 30k/3 year service interval for the VAQ diff", if I find it again I'll post it.

 

To me this just highlights the downside of not having a physical handbook anymore listing the schedules, I guess I'll ask at my year three service next March.

Even a digital handbook in the car through the radio would be handier like those in modern BMW/Minis that tell you oil, coolant, brake fluid and brake pad life expectancy.

Rather than one you have to go to a dealership and get printed off

It's on the mk8...

Never mind if we have to forgo buttons for a car based service book, I'll buy a ring binder 

I just bought a VW service record book of Ebay.
I'll use it to tick the various boxes for what's been done and store the receipts etc

Here are the repair manuals, but I haven’t tracked down the e-diff section yet…

I think VW have changed the guidance, and varied it around the world.

This pic clearly answers the frequency question. But some manuals don’t have this line at all.

The more important thing is to clean the gauze filter. VW only change the fluid.

Hope that helps those looking for the service manuals.
You can also pay vw for 1day or 3day online access, which will only show detail relevant to your variant.

Just done the same. £8. It will give me a bit more peace of mind having a physical  list to check rather than a bland statement ' serviced according to manufacturers requirements'.

One question nobody seems to able to answer for certain is whether its absolutely necessary to relearn the Haldex pump settings after changing the oil and cleaning the filter as described here.

Madstaff I thought you were going to enlighten us once you got hold of a Vagcom?
Did you get round to changing the fluid, servicing your diff yet?

[madstaff]

Not got round to it yet as I need to buy a laptop as well as VCDS.

What kind of info do you need? I've VCDs so I may be able to get the info you're after 

Also who actually manufactures the VAQ diff? Borg Warner? If so it might be worth asking them what they would recommend as a service interval, as I distinctly remember one DSG gearbox being specified as non-serviceable by VW but the manufacturer stated 60/80k mile oil change when enquired. 

[madstaff]

It's not really info I need, I am uncertain as to if a Haldex pump relearn is strictly necessary after an oil change and filter clean, which is why I've not done mine yet as I don't have VCDS.
