2018 Tiguan 163 Kw service.

[GRD]

I've just downloaded a VW Maintenance Schedule and have a questions on one of the items on the list.
The schedule is not specific to the Tiguan it says " All Models except e- Golf".

One of the items under "Additional Maintenance Items" reads

"AWD clutch : Change fluid (if equipped). - Every 3 years (AWD only vehicles)


Does this apply to the Tiguan?
Is this the Haldex? Can't see this on the list.

[Umai Naa!!]

Yes, Haldex oil is every 3 years.

Assuming your car is 4Motion.

[GRD]

Ok . Thanks for that.
Is that simply a drain and refill?
Or is there more involved? Filter cleaning/replacement?
The vehicle has covered 27,000 km and this is the 45,000 km service.

If you are changing the Haldex oil then definitely remove the pump and clean the mesh screen. These get gunked up at quite low km's and when blocked, they burn the Haldex pump rendering your car as a front wheel drive and an expensive bill to get a new Haldex pump.

There are a few (2 i believe) o rings that will also need to be replaced after removing the Haldex pump.

Here is a link to a tutorial and also this place sell the Haldex oil and the o rings etc you will need.

The key steps are drain, pump removal, filter cleaning, pump re-installation and refill.

Most DIY kits include the necessary bolts and o-rings. I'm not sure if VW actually clean the filter... I suspect they simply drain and refill.

It is well worth doing the filter - there's lots of photographic evidence of the filter being crudded-up out there in the big wide internet.

EDIT: Do'h... two minutes too slow!

They do not clean the filter, hence why so many Haldex pumps die a premature and unnecessary death.

Just in case you are unaware, the VW Service Schedule is 12mths / 15,000kms (whichever comes first).
Based on a 2018 Tiguan 162TSI (possibly first registered in May 2019 for example), you should now be due for the 36mth / 45,000kms service.
Granted, you have reasonably low kms (27,000kms), however specific to your question regarding the Haldex Oil replacement, as stated above, it is due "EVERY 3yrs" regardless of kms... So you will be doing the Haldex Oil replacement in 3yrs time once again, even if you only have 43,918kms by then (if this makes sense)...
I hope this makes sense...

Ah, I'm not surprised. Thanks for the info!

Yes its a pain Mine just turned 3 and has just 11,000km on it 45k service included the Haldex and no the filter doesnt get cleaned and the oil for it was $110 + GST. Service was $751

[GRD]

Thanks for all the replys.
The tutorial from autoIinstruct is great.
Definitely going to do the screen clean.

Finally got around to doing the Tiguan service.
I've got a couple of questions regarding the haldex part of the service.

Does anyone know or have a link as to where I can buy just the O rings?

The screen didn't look too good. The black stuff felt like light grease. There did not appear to be any particles that you could feel when you rubbed it between your fingers.
When I first saw it I thought of emulsion, water and oil blended together.
As I posted earlier 27,000 Km, 3.5 years since new. Most of the photos I've seen looked more like small particles caught in the screen although a few did look like jelly/ emulsion.

Since the vehicle has had an easy life I'm thinking of pulling the pump on the next service, hence looking to buy O rings only rather than all the bolts that came with the kit.
I think the bolts are more applicable to cars in the northern hemisphere where they salt the road in winter.

I believe this is what you are looking for: 0CQ598305 - Gen 5 Haldex Pump Repair Kit - VW Golf MK7R & Audi 8V S3/TT/TTS
– VAGPARTS Australia

Is that your car in the photo? If so, this is exactly what causes the Haldex failures as the screen blocks the oil from being able to pass through then the pumps runs dry essentials and fails.

I bet there are heaps of Tiguans running around that are essentially front wheel drive due to the Haldex failing. If the owner drives gently they are likely to never notice the Haldex isnt working. Happens regularly enough to Golf R's and most of those owners drive more enthusiastically than the average Tiguan owner.

I've just bought a 2018 Tiguan 162TSI with 26,000 km on the clock. The service history (servicing performed by the VW Dealer that sold the car to the original owner) shows that a Haldex service was done in March 2021. However I'm assuming that it was simply an oil change and not cleaning of the filters.

The car is now due for the 48 month service now and apart from deciding whether to go to the local Euro car mechanic (Stokers in Byron Bay) or to a VW Dealer further afield in Tweed or Lismore, the Haldex issue is my main concern right now.

Any thoughts on how to proceed on the assumption that Haldex filters have never been cleaned?

[Lucas_R]

Cleaning the Haldex filter is not part of the service schedule, so you can be fairly confident that they simply changed the oil.

On this basis, do you think I should be getting the filters cleaned now? That is, ask my new mechanic to do a Haldex service with this extra step even if the oil was changed last year? It's due for the 48 month / 60K service now.
