Haldex unit

[Yety]

 

Filter show as no 13 part no filter element with gasket 02E398051 ,  but check this number as it may depend on you gearbox number there are lots for the 6 speed dsg.  no 6 is the pump but can't see any filters near it, 16a could be a filter but is listed as a oil pipe. oil pipe 02E321363B ? 87,00MM black

Thanks for the diagram, but it doesn't look familiar !!

 

My Haldex unit is cast into the rear diff assy as one casting, with no bolt on construction.

Does anyone know which oil the Haldex unit uses?

Its Haldex specific fluid - 275ml is around £19 iirc.

 

A complete service on the Haldex unit at my local dealers was £59. The diagram above shows the DSG gearbox not a haldex unit though... AFAIK the generation 2 Haldex system I had previously had to have the fluid and filters changed. Again, as far I was told at the time, the generation 4 units on the pre FL Yeti are fluid change only with a non serviceable, in place for life filter.

mine too, probably the diagram refers to dsg !

 

 There's no filter to change on IV gen haldex, only oil, 750 ml can costs about 37,00 euro in Ita..

cheers

The oil drained out ok, looked clean except for some black blobs which vanished when squished?? 

I found the same when I changed mine earlier this year.

I panicked when I first saw them drain out, as I thought they were chunks of clutch plate or something equally nasty...but when I started pushing them about they just, well...squished like you say.

Erm that's a DSG gearbox, not a Haldex unit...

[wakev]

Ok it was late and had been a long hard day , here is the right part.  It is not showing any filters in the diagram or the parts list.

That looks like the filter on my Haldex. I'll try and get underneath tonight and get a pic, although dark, cold etc.

 

I tried my local dealer and looked at his parts screen, no filter or close up pics at all !!

Just got to wait for the rain to stop and get under mine for a pic.

Yeah I remember seeing that too when I did my oil change.

From memory it's on the RHS, possibly maybe halfway up or higher.

 

It's probably not on Skoda's parts list as they don't schedule it for replacement, they treat it as an integral part of the Haldex unit, just like they don't list any of the internal parts.

But there is one there though!

Bit of googling later....and some photos of the filter here:

Yup, I'm going in  .

 

In a bit I'll be out in the road trying to get a picture - just to satisfy my curiosity and to probably get the £25.00 version before I'm brave enough to take the filter cover off. There are now at least 5 versions of Haldex ?, and the interwebby is a rich source of confusion

Why bother changing that filter? The one in the VWVortex link looked clean enough after 60,000 miles and the poster managed to get things wrong with the procedure by fitting a crush washer where he shouldn't have!

Exactly my thoughts - its potentially more trouble than its worth. Its been developed and tested to not need replacing (and in doing so being pushed far harder than most users will push their units on their own Yeti) Id leave it as is. And that's from an OCD servicer.

Plus I don't think I would order anything from that dodgy looking webpage anyway, with no business address, phone numbers etc.

I'm thinking that now as well.

 

Pic enclosed of my filter

 

I'm going to get a £24.99 filter in the near future, and when I've got a dry day, have an exploratory look see.

 

The fluid draining out looked fine after the first three years of it's life, so I might swop filters at the next change - depending on the fluid state.

 

Thanks for the views chaps - but yes, Gen 4 Haldex on Skoda Yeti does have a filter 

[Kenny R]

Sure this has been posted before. On page 12 it mentions that filter is a non maintenance item...

Correct, I've already got this document. In fact there are two filters, one seems to be a coarse filter (not maintainable) on the suction side, and the replaceable one on the exit to the hydraulic system.

 

I think it's academic now - I know enough now not to get exercised
