So this morning waiting to pull on to a roundabout a small gap appeared so put my foot down... the wheels started to slip and there was a series of loud violent bangs from the front.

 

now it was wet so yeah I'd expect traction control to kick in maybe

the P-Zeros or getting on for worn, I'll be replacing them soon

 

but I've never experienced this loud banging before and googled it and sounds like 'wheel hop'... anyone else have experience of this or offer any advice?

Turn the Traction Control off, and then expect some wheel spin but no Nipping of brakes, cutting of power or like axle tramp but just XDS / XDS+ / EDL 

VW Group type behaviour.

Pirelli Zero Nero really are crap other than being lovely in the summer if not rainy.

I had this a few weeks ago on my dsg, same situation, started to wheel spin then 2 bangs the seconds being quite a hard thud. It feels like you could cause damage to the driveshafts or gearbox as it is quite a strong thud as the car suddenly feels like it gets traction. Would be interested to know what causes it so I can avoid it happening again as it does feel quite hard on the transmission. 

The XDS+ & Traction Control causes it, the wheel spin from loss of traction between tyre and road causes it.

Has done now for several generations of EDL/ XDS / XDS +,  you learn to avoid it as it is a bit of a FAIL when attempting a quick get away and a Pizza Delivery 50cc blows you off to the next lights.

Last time it happened to me it was a Micra that got the grip and shifted off the line in the bus lane with grippy green tar while the thunder clapped in my car.

Found this on the web, it does mention that it can cause damage, I will certainly be trying to avoid it happening any more.

 

Wheel hop can lead to broken drivetrain parts, including axles and rear differentials on a rear-wheel-drive car, and axles and transmissions on a front-wheel-drive car. 

 

Wheel hop is a result of this change in grip. Here is the sequence of events: 

1.) Acceleration begins with good grip. 
2.) The wheels move forward, toe changes, and available grip is reduced. Wheelspin occurs. 
3.) During wheelspin, acceleration is very small. The wheels move back again, toe changes back, and the tire regains grip. 
4.) Acceleration begins again, and the process repeats itself. 

This rapid switching between grippy acceleration and wheelspin is wheel hop. My above description of the wheel hop process sounds tame, but the frequency of the grip changes and the magnitude of the forces involved is what makes wheel hop so violent. Race tires can prevent wheel hop since they have more grip (i.e., they don't lose grip even with the toe change), but cars that wheel hop with race tires will do so in a much more violent fashion.

Mine have all done this from the Mk1 vrs Mk2 vrs Fabia Mk2 Vrs and now the Mk3. Quite normal as george says.

Good to know what it is. I have MKII and yeah the noise is horrendous, I can believe it could cause damage and try to avoid it when its raining.

 

Will have a play with turning traction control off. Although that may just encourage me to drive like a loony which is not good for the car overall. I make good progress as it is.

My Mk1 VRS was a bugger for this!

 

The Whiteline Anti Lift Kit helped reduce this a lot on my MkII but not aware of one for the MkIII.

 

Now got a 4x4...wheelspin is mostly history 

& not anything to do with Rice Puddings & Skin.

 

Crap tyres and surface wet and those tyres will spin, if just a bit, and you can get the 'Bang Bang Bang' if you really try,

actually if there is none detected then you will be FWD only will you not?

Same with mine.  Damn it would give you a fright!  Bloody jackhammer noise would erupt from the front.  It really would encourage you to be light on the throttle whenever it rained.  

My MkII was fine and the MkIII also seems fine so far.

I have a DTUK box so slightly better in the Ambrosia-Deskinning department, and am also still running winter tyres at present. I live in the sticks and drive on sh1tty muddy slippery roads constantly, and don't hang about. Summers are the cr4p Pirellis.

 

As stated, wheelspin is *mostly* history, not eliminated. 

 

Yes, there is a small amount of wheelspin before the rears hook up, but I have yet to experience the teeth rattling banging the MkII used to create. 

 

Must try harder 

Winter Tyres way to go, Winter, Summer or Santa Pod / Crail etc. 

Not much good on cow or horse **** covered surfaces though for getting off the line.

better dampers, stiffer bushes and the addition of some camber will all help reduce this - i'd pretty much eliminated this on my old mk2 with those mods.  other (cheaper!) option is to be less brutal when you put your foot down and feed the power in progressively

Really, stop that banging or reduce it with TC on?  What does it do when reduced in the noise, or is it reduced in how often you might get it?

Not in my experience of driving car with the suspension mods and crap tyres or more power than there is grip between tyre and surface with TC on.

I get it in my VRS 230. It was a bit of a shock the first time it happened, but it's easy to change your driving style to avoid it.

Id like to say it's a consequence of front wheel drive, but you can get it on rear wheel drive cars as well, anyone who drove a Capri will know!

That was real Axle Tramp since there was an axle and leaf springs though. 

So as much as it might feel like that and get mentioned the feeling is the only similarity.

No, it happens on FWD and RWD the same!

The problem originates with wheelspin at the traction threshold. E.g, it rarely happens on ice, since you're far below the traction threshold. On wet or cold dry road, the spinning wheels momentarily get traction, pulling them forward, then lose traction. The varying traction causes oscillating loads on the drive wheel suspension, in turn causing compression and release in fore/aft or up/down directions. In a self-reinforcing resonate cycle, this builds into an oscillating vibration with a vertical component.

I got this a few days after getting the car. Road was dry at the time so I wasn't expecting any problems when I dropped the clutch. It's a very scary noise so you soon learn to be more cautious! You can make still make a quick getaway if you need to, just requires a bit of care and good judgement. I prefer to let the other traffic light hooligans have their way and save my tyres!

 

I'm a bit surprised that, given the potential for damage, that Skoda don't have a fix or at least provide unmistakeable warnings on this subject.

banksie,

the thing is with the FWD VWG ones doing it with the rather basic EDL/XDS/XDS+ is you can have it happen,

then turn around go back to where it happened, stop the same as you just did,

switch off the TC (or EDL or whatever)  and then drive the same and not have it happen, 'No electrickery'   Just magic with the driver doing their thing.

if your replacing tyres mate i recommend uni royal rainsports 3's great allround tyres 

Idiot proof launch control black car with loads of power & a standard Fabia Estate with 180-190 ps sort of thing and TC off, 

(it could bang bang bang like a good one with TC on)

we know which is fastest obviously but then Electrickery or mechanicals can be so embarrassing.

Yeah, happens to mine too. I was disappointed to experience it on snow just a day or two after I took the car from the dealers... Theoretically shouldn't occur in the cars with LSD (VAQ in our case), as it should lock the differential on the percentage to achieve optimal grip, and if you go even further with throttle, ECU should cut power after certain point.

 

All other Škodas (with exception of RS 230/245 only) have usual open differential and torque vectoring on front wheel driving cars is possible only with brakes. ASR is trying to level torque between wheels by applying a brake on a wheel which has less grip. For example  it occurs in the curves, where open differential forwards torque very wrong, towards the wheel with less traction - should be opposite. It is usually inner wheel, and applying brake on this wheel will transfer torque to outer wheel, which needs major of torque (weight distribution in corner is transferred to that point). LSD (VAQ) in RS 230 should do the same. Maybe exceeding of that point leads to applying brakes, who knows.

 

 

 

Maybe some just want to go straight, and not have the car doing its thangg.
