I was driving my 190D  L&K DSG this afternoon near Crawley in Sussex. The roads were very slippery from a small coating of rain and lots of ingrained rubber.

 

Attempting to pull away sharply on to a roundabout at an A23 junction, I experienced severe axle tramp from the front axle. Its not something I would have expected to happen, as I thought that the anti-skid electronics would have tempered the onset of tramp; reducing power inputs to the driving wheels to regain grip and reduce the axle wind up. It may be that would have happened if I had kept my foot down for long enough. However, I thought that 4 bangs from underneath was enough and I backed off the throttle myself, and then put the power on more gently. It did make me wonder if the electronics are working properly.

 

Before I take this to the dealer, I wondered, has anyone else experienced this axle tramp?

Like axle tramp, called it but you do not have axles. Term still gets used.

 

Switch off the TC and see how it is when you get to have wheel spin and no brakes nipping at the discs.

Its like axel tramp... but as we dont have leaf springs.. 

 

I get the bang bang bang under acceleration in damp to wet conditions which vibrates through the body of the car. Its the traction control kicking in / tyre grip, slip, grip...  resulting in the engine . exhaust moving i thought...

 

I put it down to crap front eco tyres on a FWD

Thanks for your comments Offski and RickTT. After I thought about them, I am sure you are right. True axle tramp was a function of cart springs and a live axle.  I will try turning off the TC to check as suggested, but I am sure now, that is what it is.

Well when i get it on Fabia Twinchargers and it is huge bangs, it is the XDS with TC on.

Not with TC off.

 

With my 2016 SEAT 150ps 2.0TDI 6 speed DSG there is no XDS or TC off fitted and it is nice except when trying to really get a move on off a roundabout or away from a junction. (Crap Continental Premium 2 ContSeal Tyres fitted)

it is very much like 'Modern Axle Tramp',  just not like the Axle Tramp i used to get when sprinting vehicles with Axles.

Even with traction control off, it may still do it..

 

I always thought it sounded like the exhaust banging as the front end skipped around

This thread is very timely as I have only had my car for a couple of months and in the recent bad weather, I have experienced this thumping twice.  I was also wondering if this was normal.

 

 It reminded me of the old mini I had too many years ago which did the same when the top engine mounting that went from the top of the engine to the Bulkhead had worn bushes. (Showing my age now!!)   The torque from the engine wants to turn the whole engine in the opposite direction of the wheels.  

 

I must admit that I am surprised that a modern designed car suffers from this very  old symptom.  

 

Is this a fault that other Skoda models have or is it unique to the Superb.  If it is unique, we may be able to identify why!!

Not unique to the Superb or even Škoda from my experience. My current Octavia vRS does it, my last Focus ST did it and my MKV Jetta prior to that also did it.

It's a feature of McPherson strut front suspension AFAIK. I've had it on every FWD car I've driven (That had enough torque to break traction under power). Not caused by stability or traction control, just resonance in the suspension, probably caused by the anti-dive/anti squat geometry choices that had to be made to keep other aspects of the handling good. If you have a 4WD car with enough power it can hop like this with all 4 wheels if you pull away hard enough according to a Subaru fan I know.

I think most of us know what you are describing as will the OP as most here have been driving for a few years and have driven various vehicles.

 

I think the issue the OP is asking about is a DSG Characteristic and one that causes many concern, but i might well be wrong.

I had very similar bangs, it did indeed sound like the engine rocking violently, this was cured with fitting a 034 Motorsport dogbone mount insert (type 2)

Thank you for all the replies and in a way, I am pleased it is not unique to my car.  Looking at the information on the Dogbone Mount Inserts, it does look to be a problem with Transverse and /or Front Wheel Drive cars.  (I have just realised that I have been driving Rear wheel drive cars for the last 20 years which appear not to have this problem).

 

In researching the Dogbone Mount Inserts that Gizmo68 mentions above, I came across a great article here.

It appears that manufacturers have to compromise on a large number of things when it comes to designing cars (Performance / Fuel Consumption, Strong Engine mounts / Vibration, etc.
