Haldex Upgrade - Controller Installation Guide + Oil Change

[tigger73]

It is not the filter. What you are referring to is the Haldex pump. For this version of Haldex there is no replacement filter as far as I know. But actually there is a filter on top of the Haldex unit above the Haldex pump. But this is usually not replaced.

Ah well I don't want to be replacing that one then.

This is somewhat relevant to Haldex so thought I just add this to the thread. Also got few pictures of controller disassembly as well so Tigger73 can use in the guide if guide missing few pics.

Haldex Pump

This is not very important but I disassembled the pump as well so I'll post some pictures of it too.

These tiny little pistons pump Haldex oil to create hydraulic pressure.

Thanks Ramee.

I've "borrowed" a couple of the pictures to add to the write-up.

So do you disassemble parts of your car on the weekend just for fun?

No! these are old pics I took when I did my Haldex service. Thought I just post them as you asked about the filter and pump.

No filter on the Gen4 Haldex.

Good write-up, by the way. I fitted a Haldex Blue for a customer, and it's pretty much spot-on.

Only thing I did differently was use a Tom Thumb fluid pump bottle instead of the syringe. Takes less than a minute to fill the Haldex. I always give it a few pumps through, before I put the drain plug back in, just to give it a bit of a flush through.

Mine was "Blue" as well - is there any difference between the blue and silver performance wise?

I thought the blue ones were for Gen 2 controllers..... but I could be way off track.

Blue one in question, was fitted to an R36, which is a Gen4.

Actually there are two versions. Functionality is same but one is stealth (your one) and other is normal (blue) version. But HPA only selling stealth setup for Tiguans. There are other suppliers like HP who sell blue version for the Tigs though. Check stage 3 Tiguan build thread.

Ah cool - makes sense. I got mine from the States ( can't remember exactly where TBH), but I remember giving them my Haldex assy part number to make sure it was right!

Saw this Gen4 Haldex filter on Nuespeed: Haldex Gen 4 Filter Replacement Kit

Also available from a couple of other places including HSTuning: HS Tuning - Haldex Gen 4 Filter Replacement Kit - HALDEX.111358

Looks like it's suitable for the Tig. Maybe next oil change....

Cool - well spotted
