Here's a video of Tiguan in the snow. 4% slow motion at 1:15 on the video:

 

Is there any technical documentation available for the Haldex 5th Generation as found in FY Yeti?

Was looking on ErWin yesterday, nothing for later Haldex, well not on Skoda section of ErWin anyway - haven't looked on VW/Audi/Seat Erwin though, could be on there.

OK, so not the sexiest of Youtube videos, granted, but here's me messing around on the ice this morning.

 

At 00:14 you can see how icy it is as I slide myself towards the car

 

As you can see, drive to the rear is pretty much instantaneous.

 

I could the hear the ABS module working overtime, which I assume is the EDL in action.

 

And if you're *really* bored, here's the same video, slowed down to a quarter of original speed.

Tip: Nothing happens until 01:25ish!! 

 

01:40 is a good example of how little spin is required before the rears engage.

 

As a footnote to this thread that I started a few months ago, my car had been diagnosed with a "fault with Haldex clutch pump" by a main dealer with an estimated cost of close to £2k......!

Any one come across this failure before?

Hello Onyx123

Yes I have come across what  I believe may be the problem, You will have front wheel spin but no warning lights on the dash. The only time you know of a problem is when you cannot get grip. The vcds readout if you can get one done may show 'intermittent fault on clutch pump located on the rhs of the haldex unit. You may get a code "11" in the readout. Although many post that the pump is dead and needs replacing, don't jump the gun! If you drain the fluid (Haldex only not the 'diff'' oil) and then remove the two allen bolts on the pump flange, you can carefully pull the pump back out of it's mounting. (be careful not to pull the wire too much,{there is a clip holding the wire to the case which can be pulled out of it's socket to give you some slack}) You will then see at the 'front' of the pump a gauze  type filter. There is every chance at your mileage that this simply has a build up of sludge that is stopping the pump drawing in the fluid it requires and thereby throwing up a 'fault'. Carefully and gently clean off this sludge so the fluid can flow again. Then reassemble and fill the case with the correct oil as per maintenance schedule. Then zero the fault code  and try it. This may well cure your problem and save you nearly £200 on a new pump. If you cannot test it with a vcds, then know that the engine must be started to run the pump. (at least 400 revs needs to be sensed to trigger the pump). Sorry if the post is a bit rushed but it's been a long day. Hope this helps. Post if it does as it could save quite a few owners some grief and stop a few dealerships taking owners to the cleaners!  This is a common fault and Haldex know about it. Regards Dave
