Done about 5,000km in my Superb 280 and noticed that it's rather more likely to spin the inside front wheel pulling out of a junction etc. than I would have expected before power is shifted rearwards. It's not as if the car is just sitting there, spinning its wheels, as there is always drive, but a spinning wheel is a bit unseemly for a supposed 4x4 car!

 

I know it's a Haldex system so not 'proper' 4WD but I'd never noticed this tendency in the other Haldex-equipped cars I've proper experience of (170ps Yeti, 190ps Tiguan). Yes, they have less rated power than than the Superb but the delivery at low revs is probably equal or even superior and in any case, I've hardly been doing full-burn acceleration in the Superb and still gotten more than just a chirp.

 

It may be because the car is on winter tyres (although shouldn't that improve grip in cold/damp conditions?) but it does seem a little odd.

 

Anyone else experience the same?

How cold, how damp, what winter tyres what pressures?

  Kind of relevant. Still tyres, road surface and need for traction. ie good traction.

Well, it's never really been below freezing yet, just normal November damp roads. Tyres are Bridgestone Blizzak, so proper M&S tyres, and are at the recommended pressure for 18", I think 2.5 bar.

I have also noticed a slight tendency to momentary wheel spin when the steering is significantly turned, eg turning at a junction. My Subaru never spun a wheel ever. But that is probably just the Haldex system and electronic “virtual limited slip” diff vs proper 4 wheel drive with limited slip /viscous couplings all round. Mind you, I subsequently had the Haldex fail completely, pump failure, and this is not accompanied by any warning lights or messages whatsoever. So if the wheelspin is anything more than 1/2 wheel rotation with a lot of steering angle, I’d have the Haldex module checked for fault codes. Apparently there is TPI relevant to the problem of early pump failure on the Haldex 5 units  ( mine at 20,000 miles) so I’m hoping the new pump they fitted under warranty is modified to prevent such early failure.

Hi, My Mk11 has 4x4, had it 2 yrs and no noticable wheel spin in any situation, has been remapped but don't tend to overuse throttle

on getaways and it's on summer tyres. Some previous threads have noted 4x4 wheelspin and these tend to indicate a problem with the haldex. But at your mileage I wouldn't think thats the case, just noted you've got a 280....right foot too heavy with some steering lock on ;)?

" This system attempts to engage the rear wheels when the front wheels start to slip

The system needs an element of slip to function, but how much is too much ?

Usual thing to ask a customer/ owners are these new tyres s& till green without much use yet, even though winter tyres so release agent on them.

And other than a junction does the car behave the same starting on a straight on a cambered road or a flat one.

They tyres have 5,000 km under them, I'd hope they were well scrubbed-in by now. They've certainly been properly used and display appropriate grip in corners, braking etc.

 

I recall I did do one launch start, slightly uphill in damp conditions and there was also a bit of wheelspin at the front. In the dry it seems fine.

 

Other than VW Group Haldex cars which I haven't seen this in (as above), my only experience has been permanent 4WD in the likes of Evos and proper off-road machinery,

The origial Haldex system needed an element of slip to function, but later ones including the Haldex 5 on these cars, doesn't. They have an electric pump to operate the Haldex clutch and a computer connected to the car's systems so that it knows lots of parameters such as throttle position, gear, engine torque, speed, steering angle etc etc and it anticipates any propensity to spin the front wheels, engaging the clutch before it happens. So it is proactive, not reactive. In theory at least!

Yes, put some diesel between the tyres and asphalt or have the car aquaplane and some how its not all so 'simply clever'.

That was my understanding too, and I would have assumed that something like 'speed=0, steering angle>5°' would be one of the parameter sets that would preemptively lock things up a bit. 

Something isn't right. There should be zero front wheel spin on Haldex equipped cars.

 

There have been several similar posts on this over in the Yeti and Octavia MkIII forums, most of these were as a result of a non-operational Haldex system.

 

Get it checked out whilst still under warranty.

My 16plate Yeti is very difficult to spin wheels, tried it to see how it performed.

Only time has been with virtually full lock on a wet road and then it is only a very slight spin before the rear wheels grip.

 

Same with my Freelander 2 - nigh on impossible to spin those wheels.

 

FYI - both are autos

That said, the 280 engines do put down a lot of torque in 1st gear compared to other variants.

That'll do it especially if it is a manual

I just spent an hour on ERWIN looking at various stuff. There is a TPI about the Haldex 5 pump tending to fail, and there is a modified pump called up in the TPI to be fitted in case of failure. So if there is any doubt, get off to the dealers to have it checked with a view to the modified pump being installed. Of course your car may already have the modified pump, mine was built early 2016.

Yeah, it's only six weeks old!

Should be OK then!

Given I'm in an almost identical situation, 280 L&K in Luxembourg on winter tyres, it does seem to be normal (unless both of our cars are suffering the same issue  ).

 

I've only noticed wheelspin from inside front at junctions since putting the winter tyres on and the fact roads are generally pretty slippery at the moment from that weird film the roads seem to get at this time of year after the first salting. With the summer tyres on, although bigger sizes (235 v 215, 19in v 17in, I didn't suffer any problem when pulling hard out of junctions either wet or dry. One of my friends with a Range Rover also mentioned the other day that they were getting more wheelspin than expected out of junctions this year. Maybe they have added some additive to the salt they are putting down to make it stick that perversely gives the road this slippery when wet feel.

 

Oh and its true about new tyres still having the release agent on when brand new. I did pull hard out of a junction on a dry road a day or so after I fitted the new winter tyres and got surprised by all 4 wheels spinning and getting a huge tankslapper going down the road. Wished I had chosen the brown interior after that moment.........

Mwhaha  Took me a second to sink in...

Something that I found that works is using VCDS to change Haldex wiring logic from normal to  "Increased Traction". 

^^^ ? 

Does that make an automated phone call to the Roads Department in your area to put out operatives to clean and dry the road surfaces?

That would be 'Simply Clever'.

It did, but from memory even the Gen 1 Haldex only needed less than one turn of wheel spin to engage the rear wheels which is not noticeable

I have re read this thread again, trying to figure out what is normal behaviour for the Haldex system on these cars. I get brief wheelspin pulling out of junctions on moist roads, with a bit of camber and reasonable lock, before it settles down. Its certainly nothing like the wheel-spin that I used to get on my Octy VRS on a brisk pull away, so I’m pretty confident something is kicking in to aid traction. Not noticed seeing any traction control light illuminating when that brief spinning occurs , though I’m usually concentrating on the road more than the dash, when turning out of junctions. 

I wonder what others have experienced lately, with the 280, in similar situations?
