shudder / haldex

[Sasquatch]

Not quite sure how it is over there, but over here I can see the dealers point to some extent.

If the importer won't pay for warranty work, then it's down to the customer. The dealer is stuck in the middle and they won't embark on any warranty work for which there's the slightest risk they won't get paid for it.

With modern IT systems the warranty administrator at the importer will want photos, part numbers, all the rest of it, so there's very little lattitude for the dealer to be stretching the truth or trying to obfuscate as to the cause of any fault, and there are heavy contractual penalties it they get caught trying to do so.

They're in business turn a profit, and financially subsidising a customer by swallowing the cost of warranty work themselves would soon have them looking at bankruptcy.

They don't turn warranty work away lightly. It's a guaranteed payday (assuming the work is indeed a warranty comcern) and the bread and butter of their profit comes from warranty work - that's why there are so few Honda dealers, it's difficult for a workshop to turn a profit on cars that don't break very often. If the dealer has spotted an inconsistency they can be damn sure the warranty administrator at the importer will spot it and keep his wallet in his pocket.

So I would suggest ire is, for the most part, directed at the importer as it is they that pay for warranty work and they make it very clear to dealers in advance what they will and won't accept.

I tried just rolling to in intersection with foot off the throttle and do a hard turn while still rolling and there is no noise so it seems it's just under load.

Perhaps you could unplug the connector at the Haldex pump (just to take it out of the equation) and verify if the judder is still there under load?

I Have exactly same problem. 2017 van
In the past the diff lock has randomly come on but thats a past issue, and didnt seem to cause any lasting problems
slight judder noticeable when accelerating out of junction and turning right as if a wheel slightly locking, all fine when driving straight, and turning without any load seems ok.
I disconnected the electric feed at the diff and the noise/problem has now gone and van drives fine - albeit in 2WD.

Next job is diff oil and a haldex service and new oil - fingers crossed....

I think Roadrunner doesn't have a difflock on his van, even though it sounded like a difflock problem.
Did you disconnect the Difflock or the Haldex?

I disconnected the feed to control box on diff haldex guess.
have previously pulled fuse on diff lock.

update:
Yeah I don't have a difflock (sadly)
So I rang VW Australia again as there was no update/communication for a while. Different person looked into the notes and said they have not heard back from my local dealer and they tried multiple times to contact them. I told them WTF and if they get the point how I feel as a customer.
Funnily enough that same day I got a call from my local dealer with a completely different tone. Said they need the car back for a week and I get a loan car at no cost.
They want to send the haldex oil for testing. I told them that they changed the oil last time and he said they hope there is still some contamination from before there (as in left over oil) and they want to proof that the wrong oil was used.
If they can't proof it it is warranty and I get a new haldex. If they proof it was the wrong or contaminated oil they blame the previous dealer and they have to pay for replacement haldex. I double checked that no matter what I get a haldex for free and he said yes.
Given that was just some phone call with no proof I put it all in an email to VW Australia again and wanted confirmation.
They called later and said they spoke to my dealer and he confirmed everything I listed in my email including it's still fine to drive as I have a 6000KM trip planned next week.

I have a feeling this is not the end but it's something. Car booked in mid May again. Hope it doesn't and up on a tow truck on my trip.

That is sounding a lot more positive. Keep us posted.
