Hi Dave, Is the steering wheel moving with the swaying motion?
Are tyre pressures correct? Shockers leaking?
Hoggy.

 

Does it only happen when returning from the pub? :lol:

 

Just to be sure, are you feeling this as a rolling motion along the roll (x) axis? If so, it makes sense you wouldn't feel it on a curve as centrifugal forces would keep it leaning to one side or the other. However when you come out of a turn and continue straight, does the car continue to roll left and right, left and right?

If so your suspension may be toast. Might be worth taking it in and having them check for leaks or a collapsed spring.

 

It reminds me times when I have had Audi A6 with longitudinal V6 engine. When I pushed the accelator (on neutral), I felt a strong swing around the x axis

 

Hoggy, the steering wheel isn't moving.

Yes its along the X axis, but the car isn't noticeably moving, but it must be slightly, as I'm rocking from side to side in the drivers seat. When I get out of the car and no longer moving like that I feel a bit sick.

I haven't looked at anything yet as I have only had the car for 2 days. But I will check the tyre pressures and bounce each corner of the car.

Its funny it doesn't happen when returning from the pub, everything seems fine officer!

But thanks chaps for your replies.

hahaha

I would highly recommend a 4 Wheel Geometry Check, you'll pay way more than '2 wheel alignment' at Halfords but I can assure it is worth every penny. I had mine done for £120 and now it drives like an arrow in a straight line. This is probably something I'll have to do every 6 months however, as I let the girlfriend use the car once a week, and sometimes the dashcam doesn't get every curb she hits.

 

I once had a car that was 'jumping left and right' on motorway irregularities. When getting an alignment done we found out that the rear axle had toe out instead of toe in. As a result the rear tyres were in a constant battle with each other as to where the car would go next. Think of a fork lift truck that is steered by its rear wheel(s). A small angle has a large effect. Similar on a car.

 

Thanks for the replies.

Going on that I have looked into getting a 4 wheel alignment done. There is a body shop by me who said they have the latest Hunter machine. He said it would cost £85 not sure if there's vat on top of that! I'll book it in and when done I'll update this post.

Cheers,
Dave

 

Ask them before hand if that price includes rear wheel adjustment. There seems to be a lot of advertisement for 4 wheel alignment but only includes front wheel adjustments in stated prices. The rear is extra.

 

I had something similar, but more in the Y-direction. Checked tyre pressure and turns out the guy who put winter tyres on, overfilled the front right tyre. Bought an electronical tyre pressure meter, so won't have that happen again!

 

Check the tire tread as well. If the wear is different enough from tire to tire the car will have a tendency to "track"

When going over markers on the road (I.e. lane changes) do you feel the same sensation?

 

Yes the sensation is like going over markers on the road. The car is moving around from left to right, even on a smooth road with new tarmac. It feels a bit like wind buffeting. The car is moving slightly enough to rock me from side to side, but the steering wheel doesn't move.
I will drive over road markers to see what happens. Around corners it handles really well. Or though it does wallow around a bit when hitting a small pot hole.

The TT is not a Passat SE, going over road markers will give you some feedback that you will feel. A pot hole will feel like you have ripped a tyre, I would imagine this is a normal sensation.

 

Same as above. This generation is known to have a busy ride. I know what you mean as even on a smooth straight road you still get a jiggle. This is normal as far as I know. I have changed wheels and tyres since getting mines and the sensation remains

This doesn't sound right to me. You need to get underneath and check all the suspension components have no play and the shocks are working properly. (Cheapest way to check might be to take it for an MoT. In my experience MoT men are quite good at spotting suspension play). Does your car have the fancy electronically adjustable damping? I have no experience of this system but anything that complex and clever could go wrong.

If all seems well then try driving the car at different steady speeds (50, 60, 70 and so on) to see if the problem gets worse at certain speeds. Let us know what you find.

For the car to maintain an oscillation there must be a forcing vibration (something causing the car to move) AND the damping of that vibration must be low enough for the oscillation to sustain. The forcing vibration could be aerodynamic, imbalance in rotating parts or a characteristic of the road surface. Whatever the cause the car should be designed to dampen the motion to an acceptable level. It is quite common for some cars (and particularly lorry cabs) to 'nod' at high speed. I used to drive a lorry called a Ford Transcontinental that was notorious for this (very tall softly sprung cab). We used to give potential customers rides in it (it was a research vehicle) and many of them complained they felt sick afterwards because of the motion. I also own an air suspended Range Rover, this too makes some people nauseous.

I would strongly recommend you check that everything in the car suspension is working as designed first (the shocks would seem an obvious candidate for suspicion), but if all else fails then maybe a set of adjustable shocks might be the answer as you could stiffen them up until they damped the motion to an acceptable level.

I have never observed such problem with my TT. It must be some problem with wheels/tyres/geometry/suspension/dampers/plays there.

 

I dont know how long you have owned it for now, but did you get any warranty when you bought it?
If it was a garage you bought it from, take it back and get them to sort it.
I had a set of chineese ditch finders on mine when i bought it. Driving it in damp conditions was scary until i changed the tyres which transformed the car.
If yours has mag ride, it will feel very firm...

 

Thanks Chaps for your replies.

I will get underneath the car and check the suspension. I tried buncing each corner to check the shocks but the springs are quite stiff so couldn't get enough movement to check them. Its the standard suspension.

The car isn't rocking from side to side but more as Enky08 said a jiggle. It moves left and right, no rocking, but the movement rocks me. The steering wheel is straight, no movement and I don't have to correct anything. It does it at any speed, but it does vary with different road surfaces.

The car drives well around corners wet or dry.
I did buy recently from a trader, with premises and showroom. I have a warranty and have contacted them about the problem, they are slow to reply.

 

Worn out suspension bushings can be alarming to see when they're worn, compared to a new one, this is actually next on my list, all front suspension bushings and engine/transmission mounts and whilst at it both drop links

 

Do you know how many bushes there are that can be replaced? And do you know where are you getting them from?

 

There are quite a few of them, I did see a diagram recently which came up in a post showing them all

Thank you for that. Yes there are quite a few! But it shows clearly where they are and how many. Cheers

 

I would imagine something like this could effect handling, mine is 12 years old so it's probably time I replaced the lot.
