Can somebody advice whether it is possible to switch OFF the AWD ( 4x4) system using the VCDS  in a Yeti 4x4 so that it runs like a 4 x 2 vehicle...

I beileve there are some sensors like rain sensors which give signal  to the HALDEX differentials

Any reason why you would want to turn it off? Not that it can be done with VCDS I think, but I'm curious why you'd want to.

Could I just ask why you would want to do that and what advantages would there be by doing it?

It's times like this you find out who has you on their "Ignore" list...

Pull the fuse for it out.

Go on give me a clue, who?

Well, I thought you, because you pretty much repeated the question I asked. :p

Look at the timing of the posts, doing it at the same time.

As said, what's the point, given that most of the time they are are running in 2WD anyway?

I have heard the saying before "dont use it, lose it" and feel that if the 4wd was disabled then it would quite possible either seize or cause other problems when it was later re-activated. 

 

The 4wd system been active wont contribute too much towards the fuel consumption if driven sensibly, its the additional weight that would do the most damage - if you were wanting to save fuel.

Hi my dear colleagues,

 

I'm going to be a owner for a Yeti shortly ( second hand ) and therefore knowing a little about AWD cars made me think of such a situation where AWD have some issues such as the following

a) Tires wear out -   to what KM kength would the tires have life 

 

Is the Skoda software smart enough to actually put all the energy onthe front wheels.

 

c) brake wear out ...may be at 20000 KM or is it later 

 

d) I heard from another forum that the rain sensor in a yeti is connected to the haldex system and therefore might applya negligible amount of brake to the wheels  ?

 

Your feedback and experience is important to me .....

Most of the power will go to the front wheels if not needed at the rear, It's a very clever system.
All Yeti's will give a light brake to the wheels in wet weather to dry the disks but it is only very light, the biggest problem if that is what it is is the rear brakes can wear more than the front because they are not used enough to remove corrosion from damp weather.

Brakes should last WELL OVER 20000km.

a/ Tyres do not wear out any quicker.

b/ Yes it is.

c/ No they don't.

d/ Who ever told you that doesn't have a clue!

 

The Haldex 4x4 system is very clever and you do not need to worry about it.

Leave it alone.

thank you my friend  !!       OK...will drive without messing with the 4 AWD mode....

 

 

But then again is it really really possible to SWITCH OFF the AWD .. ?  Has anybody tried this before ??  I am just curious....

I am also worried that only 20000KM for the brake pads...Can it go beyond 30000 KM.......My Hyundai Azera 3.8 L limited goes beyond 45000 KM  ! !

Read the above posts,  maybe someone has had that but the norm should be 5 times that at least.

Although it's not due to the haldex, cars with ESP will lightly apply brakes in heavy rain to keep the discs dry and reduce stopping distances.

Answered in post #5 above?  Fuse out = no electrickery to feed the Haldex' brain.  That said, I don't know for sure how it fails in such a circumstance.  I'd assume it would just disconnect all drive to the rear wheels.  Also, I've no idea how good this would be for the health of the Haldex, or the car as a whole, over an extended period.

 

As others have said, the scare stories you seem to have heard are far from reliable.  Best just to leave the car as it was designed, and enjoy driving it rather than angsting over stuff that really is of no consequence.

As far as I understand , the Haldex system works on maintaining pressure electro mechanically after it takes the input from the ABS and the other sensors ...is there a elevation angle sensor in these systems.

I would sell your 4x4 Yeti and by a 2 wheel drive one.

End...

 

First time I've heard of someone buying a car they didn't want, and then removing bits to turn it into something they'd rather have.

For what is is worth, my 4WD 2.0 TDI 140 is on 60,000miles and (as far as I am aware) still on its original pads and discs.

 

I bought the car on 25k so it has either covered the full 60k, or 35k with the same discs and pads - either way, more than your estimated 20,000km (12,000 Miles)

this is v. good information....now I see that the yeti is quite reliable on brake pads....

My car has covered almost 50,000 miles - or 80,000km.

And is 4x4.

And still has original brakes - all with plenty of life left in them.

I think you will find he has buzzed off!
