If you know a fabricator they could make you a roller and you could try this:

Thks Bogwoppit

I found this info, and will see if I can get the car on vagcom again, perhaps give it a reset?

I think a pump relearn is to be carried out after a filter clean.

This is so the pump control calibrates the power required to hit the target pressure.

Blocked filter = more power required due to the restriction.

ok thanks Madstaff!

Is there a chance they didn't do this after the service last year?  And that could cause it to not work correctly?

IMO i highly doubt VW remove the pump, clean the filter and perform a pump relearn.

I don't think VW dealers even acknowledge a diff service is required every 3 years TBH.

See other recent posts on this subject including my own recent experiences.
My dealer insists VAQ is a Borg Warner sealed for life item and does not appear on any service schedule.
Therefore they won’t touch front diffs unlike Haldex.
Their workshop techs confirm this.
As far as I’m concerned, they will continue to service the car and I will continue my VW extended warranty.
Maybe I’m wrong but “ if it ain’t broke, etc”

Sorry I meant would they do a relearn reset after a fluid change?  Or is it only when the pump is removed and filter cleaned?

thanks will have a read of the thread.

I doubt it as there is no mention of doing a pump relearn after a fluid change in the workshop manual.

Pump relearn after pump or gauze filter clean.
