Mainly for interest, but also as I’m coming up to third year service, I’m wondering whether to request VAQ service

I’m only on 19k miles and I suspect the oil is perfectly good.

Anyone know if a scan tool can tell how much the diff has been used?

From the many forum posts I've seen this seems to be a third year service although nothing is written down in the UK at least, good luck trying to find a UK dealer who will do it without a lot of discussion, unlike the DSG service which is purely based on mileage at 40K, again you will need to book that in yourself as there is no prompt from the car.

Interested to know how you get on...

The suggested service interval is 10k miles or 3 years on the diff.
I would be keen to change the fluid after your 19k miles.
I don't have it to hand, but Obd11 does show some data on the diff, such as time spent of diff overheating & wear.
I have had diff service on different Gti, other than peace of mind, I could not notice any difference in the drive.

I’ve just booked my car for service, i was offered a brake fluid change but no mention of VAQ service.

I’m inclined to leave it for another year or so because
- mileage quite low
- mostly relatively sedate commuter miles
- debate as to whether it is or isn’t a serviceable item
- most people report the fluid they replace looks as clean as the stuff they put in
- I haven’t heard any reports of VAQ failure

Thanks. I’ll look through the OBD menus, if you can show me where to find the data when you get a chance, I’d be interested

This guide includes a part on OBD11 functions, once you enter- Control units> Lock electronics> Live data.... You can tick off the options you want to view in real time.

I wouldn't hesitate in changing the fluid, it's a simple diy, covered elsewhere on this forum.

Filter as well???

If I remember from YT video's it looks a PITA as there is a cross-bar blocking part of the process.

I still don't understand why VW main dealers don't have this on their service schedules for the PP?

You would think that they would want any way of getting a few £££ from us.

Yes I’ve read that the filter collects a lot a debris, but no one changes this.

I think all that happens is that good fluid gets swapped for good fluid.

I did look through the lock differential/ live data list- couldn’t find anything on time spent.

I read on one thread that the US market is very sensitive to service costs, so VW didn’t want to include this as part of the schedule.
Secondly there is genuine disagreement as to whether it’s necessary. Mk7 is now over 8 years from launch. These things still aren’t going wrong- and I’d bet most cars haven’t had the diff serviced.

I've just had my 3rd engine oil change done at 26,000 and the dealer did mention an LSD oil change was due at 30,000. I also asked about the DSG and was told its not due till 80,000.
Looking online at VW service schedules it does mention that 7 speed DSG is 80,000 but had in brackets R model.
Is the PP DSG 7 speed different to the R DSG?
