Hi all,

Hopefully you clever people will be able to clarify the suspension/drivetrain setup i have on a 2016 2.0tdi 150manual Scout.

 

Am I right in thinking it has:

 

1. Multilink rear suspension rather than torsion beam

2. A gen 5 Haldex

3. Will it have Vaq diffs

4. If it has Vaq are these on both front and rear axles .

 

Thanks in advance

Only the PFL 230 vRS and 245 vRS have the VAQ diff and its only on the front axle.

 

It's a diff designed to overcome the inherent weaknesses in higher powered FWD cars so would serve little purpose on a Haldex 4WD car.

As above, there is no VAQ on the Scout only the 'enhanced' VRS also as above.

 

All Octavias have ESP that will act like an LSD using the brakes to control spin of the wheels. It is quite effective if a little wasteful of energy and brakes.

Differentials like the VAQ are useful in a Haldex just as they are in a 2wd as they stop the ESP cutting in so often maintaining momentum in corners. Haldex only controls front to back, side to side is still controlled by the diff (or ESP)

 

People have used LSDs like Wavetrac to good effect in Golf 7R and Audi S3 on one and both axles, but I would say in a Scout the ESP will work just fine.

Thanks folks,

I was wondering if it was the brakes that stopped spin on one corner with the haldex shifting power between front and back.

Its over 12 years since i had an audi with haldex and was really impressed back then.

Since then ive had a 2wd otavia estate and never felt confident it would find grip if it went off tarmac but in the 5 months ive had the scout its really impressed me once again.

And in off road mode the hill decent contol works really well.

I dont think id go back to 2wd but ill wait until the winter comes to see how the 4wd copes.

Thanks

12 years ago was around the transition from Haldex Gen 3 to Gen 4 so you may have had Gen 3.

 

There is a marked improvement Gen 3 to Gen 4 not so much Gen 4 to Gen 5 (as fitted to the Octavia) but still an improvement. There is much less 'waiting for slip' and much more pro-active power transfer to the rear.

 

I have had Gen 5 for three years now and cannot fault it. With the right tyres I have not found its limits. I find it best not to over-think it, just put your foot down and the car does a very good job of sorting it out.

That's XDS not VAQ. I think the Scout has XDS but not 100% sure.

EDL, ESP, XDS : it all boils down to the same thing, it brakes the wheel with less traction to send torque to the one, two or three that have it. Torque vectoring using the brakes.

 

A VAQ diff is like a Haldex coupling across the front axle, electronically controlled clutch system that also acts like a conventional LSD.
