VW Tiguan 2009 Changing Haldex,Differential,Manual Transmission and Engine Fluids

[motozi]

Hi, I'm new to the forum. I've got a lot of help from the writings of this forum. So, I guess it's my turn now. My Tiguan is 2009 125kw Diesel 6SP manual transmission. I have 120k kilometers ~74k miles on my Tig.

Changing Haldex,Differential,Manual Transmission and Engine Fluids:

You will need at least the following:

10/5mm hex key (front & rear differential/Haldex and manual trasmission fluid plugs)

4mm hex key (Haldex filter IV only)

32mm Socket/Ratchet (Engine oil filter change)

T20 Torx Bit and Driver (You need to remove that black plastic plastic cover under the car oil pan to see manual transmission fill plug. If I remember correctly you can use 20-tox bits.)

commet:
ALWAYS remove the fill plug before you remove the drain plug.

WOW! Excellent first post!

Welcome to the forum

[liquidvw]

agree. good first post. One comment. ALWAYS remove the fill plug before you remove the drain plug.

Well done, thanks!

Thanks for the images.

I noticed that you did not post a picture of "Haldex Fluid Flowing". Was it too bad? Is it the first Haldex Fluid change (120K Km)? Did you give up changing the filter?

We had a little rush when we changed the oil. For this reason, I forgot to photograph every oil change. Haldex oil had been changed once 60k km but they we still quite messy and black. I did not have a new filter. I think Neuspeed kit is too expensive. I would have cleaned the filter but I did not get it out of the slot.

USA Edge 5w-30 worked great in my Tig. I had a Caterpillar UOA done.

A note on the MTL, new VW MTL is VERY thin, thinner than an ATF at 6cSt!

As much as I like thin fluids, I actually went up in visc to about 10cSt with a blend of Redline MTL. Redline now offers a midweight MTL 85 or so. I went up in visc due to my extra power from APR, plus thicker fluid makes it a lil quieter and smoother.

Bottom line, 75w-90 in the man trans is a mistake. Carry on.

I live Northern Europe and in the winter outside temperature is up to -35 degrees. So at least here I would not recommend thicker oil in manual trasmission. In cold weather I have to use Webasto auxiliary heater and Defa engine heater to warm up engine cooling water.

Smart choice and thanks for the pictures.

Thanks for this post... I am about to change the haldex oil... plus filter...

Haldex oil I already have but I do have trouble as others to locate the filter as VW does not have a part number in their system. The only way I found would be to purchase the NEUSPEED kit which sucks $90 out of your wallet; which is quite expensive as I just need a paper filter for not even $1 production cost.

Does anybody have the filter part number; maybe a VOLVO part number ?


How do you feel about changing the transmission fluids ? Many people told me not to change the transmission fluid at all just check the level and add if needed ?

Thanks, Dietmar

Changing the ATF and MTF is essential.

I'm looking at Pennzoil Syncromesh for my next MT fluid. It's pretty thin, but -35f is supercold. Some guys in Canada use Mobil 1 ATF for MTF in supercold, I can see the logic.

I have this graph I can share. M1 ATF should be somewhere below Syncromesh...

[BrutalDictator]

Ok, I generated a new graph with M1 ATF at a bit lower temp. It is literally a hair thinner than Syncromesh across the board. That gives you an idea of how nice and thin Syncromesh is in cold, and how advanced of a product it is.




I couldn't include the two oils in this graph because it'd skew the range up.

Thanks Motozi - a comprehensive guide which will help no end!!! A quick question, did you change the Haldex coupling drain plug at oil change or did you reuse the old one?

IF you changed the plugs, do you have the part numbers for the replacement ones and any pictures of the actual plugs for private message?

Thanks,
Andrew.
