Thank you!

 

I live in York but commute to Durham so pass Stockton via the A19 daily.

 

I'll be sure to look them up when the Kodiaq is due!

 

👍

Oh that could work out well. They have 2 courtesy cars too, another bonus as not many small indy’s offer them.

Hope it wasn't as clean as mine, you might want to carefully check the video.

 

If it was Haldex fluid they drained, & I sincerely hope it was, then if it was clean the system has not ever been working, if it was dirty then the pump filter needs cleaning imperatively.

Thsnks for your concern, sounds like you had a 'mare.

It was over a year ago now and no probs and the haldex works judging by the scrabble you can hear from the rear pulling out swiftly on a damp morning. It was after 2 yrs rather than the defined 3y as the mileage was high and I wanted to be sure. It lived its life on the m-way so not much 4x4 action needed? Hence the cleanliness?

I think the biggest problem is most likely that the gen4 had a filter that needed cleaning and it was a serviceable part. However the gen 5 did away with the filter and just use a gauze (which still needs cleaning) so a lot of the dealers seem to think there is no filter to change or clean therefore won’t do it !

Exactly.  Volvo tripped up with the same issue on early XC40's.  Their dealer network were adamant nothing but an oil change was required; resulting in many p'd of owners who experienced premature failures.

[...] if the maintenance manual doesn't request it, I would assume that it isn't critical.

Please advise.  

I think that's what most people are saying, Skoda don't check the filter, their workshop manuals tell them to replenish the oil and that's it.

 

It would seem there have been cases where the filter has been contaminated and damaged the Haldex, meaning ignoring the filter (like a Skoda main dealer does) is not necessarily a good idea.

 

 

May be not critical (upon VAG Designers), but does not cost much to clean/change, I agree. Fortunately, one can easily find tutorials on youtube.  

 

Yup gen 4 had a replaceable filter (even though it seems Skoda denied its existence). Gen 5 doesn't have a replaceable filter. It does have a different pump that is supposed to be more tolerant of gunge and has a built in gauze filter. When I changed my Haldex oil at 30k miles it was incredibly full of fibrous gloop. I also removed the pump to clean the gloop off the gauze. I therefore support the idea of doing the changes more often, I intend to do mine after another 20k miles. To the dealers who worry about nicking the O rings, well why not fit new O rings when you replace the pump!?! I can't remember how much an O ring set was (and you get the two bolts as well) but it wasn't much. And in the end I didn't use the new O rings, I kept them for next time. But no leaks!

After having done mine (ignoring my stupid error) I completely agree with you, the fluid was dark & discoloured & the pump must have been really struggling to draw fluid through the gauze screen, I wont call it a filter cos it aint, its a tiny surface area, the best analogy would be running a vehicle for life with no filter element in the oil filter housing and relying on the gauze oil pump pick up screen to filter out the contaminants and have enough surface area to still allow the pump to run at 100% efficiency.

 

Oh and while doing so emptying all the clutch dust from the bellhousing into the sump on a regular basis.

I didn't change the Haldex oil yet, since Skoda recommendation is every 3 years. According to yearly mileage, I was intending to replace it at 60000 km, upon DSG oil replacement.

 

Anyway, when I change the Haldex oil, I will definitely remove the pump to clean the gauze filter and change both seals before reassembly. I viewed several tutorials on youtube and it looks quite simple. You effectively only need to remove the pump (mounted with 2 screws) to access this gauze filter (circled in blue below), which is also fixed with 2 screws.

I've found the seals P/N: see reference #7: 0CQ 598 305. It's around 15-16€ (found on ifinterface.com):

I would do it sooner rather than later! The main difficulty is of course access, if you don’t have a proper car lift. It was a little difficult to free the cable between the pump and the controller to allow enough slack to be able to extract the pump. Also the drain plug was very tight (or was it the fill plug, can’t remember) with a rather small hex socket and made of soft material, so I needed a new plug - but it was cheap.

@nicknorman Thanks for the tips to ease pump removal. 👍

My car is only 43500 km so far, and I mainly drive on motorways. Thus my haldex should not be activated too frequently. I think one shouldn't need to become paranoid.  

Considering Skoda workshops only replace oil without cleaning the gauze filter, I'll pay much more attention to it anyway.

Hi.

I'm towing a 1500kg (when loaded) caravan "Solifer S9" with a superb 4x4 DSG6 190hk 2017. 

My car has done 120 000km and no problems with the Haldex yet, maintenance performed according to service plan, last service included oil change of the Haldex unit.

 

I like my superb but it isn't an excellent tower... The DSG box makes it struggle and jitter when doing those fine adjustments on uneven ground.

Compared to our second car XC70 D4 AWD (also haldex 5) the Superb has a jittery gearbox that doesn't give me any confidence when manoeuvring and it lacks low end grunt - both of above makes it a lot harder and dramatic to use the superb for towing compared to the XC70.

When using the car fully loaded along with the caravan the springs of the Superb are a little bit to soft (mine is the DCC version).

 

Also - when crusing at allowed  speed (80km/h) the Superb tends to shift to highest possible gear just to a few seconds later shift down again, this is repeated continuously and the only way to get rid of the behaviour is to stick it to sport or manual mode.

 

This is of course subjective and above only reflects how I experience the Superb when towing.

@Baverhanne

Though, I don’t tow at all, I agree with the quite disappointing behavior of the DSG6 gearbox.

AKAIK, the gearbox software has been modified on MY2017 (at least) to comply with Euro6 norms and lower CO2 emissions.

But this has downgraded its confort on daily use.

Simple example: I always feel puzzled, when entering smoothly in D3 in a roundabout, the gearbox suddenly shifts to D2, upon gentle acceleration to exit the roundabout. It generates an unexpected pitch for all passagers. Very uncomfortable. 
According to the Sales Manager of my local dealer, this has been improved on MY2018 which are DSG7 equiped.

With regards to being activated the Haldex Gen4 and Gen5 unlike earlier models get "activated" quite a lot. As soon as you are asking for more accelerating and automatically from every standstill you use 4x4. In addition when wheel spin is detected like on Gen3 you use 4x4.

Are sure about that? 🤨

AFAIK, as long as the grip on the front axle is sufficient and front wheels don't slip, the rear axle is not activated... 🤔

You are correct.

Have a look at the Tiguan Gen 4 Haldex. Go to function a the back.

While the Gen 5 is a different constructionmost applies in the same way. It receives its inputs to engage in different driving situations not just when loosing traction. It assists in cornering to reduce understeer... You can also buy a race controller for the Haldex to have permanent AWD, but never get more than 50% to the rear axle.

Thanks for that, I have printed it out for bedtime reading & then it will be spiral bound to join my collection.

 

You are right! Page 19 describes it and it bears out the "feel" I get when driving, when accelerating through bends or exitting a roundabout it does feel planted like my old 4x4 Sierras but without the drag at parking speeds.
