UK vehicles are set basically for UK roads and cambers.

(they cope when overtaking and crossing the white line and driving on the wrong side of the road you will notice. thats on the oposite camber from your normal side of the road.)

Some vehicles springs are Handed and suspension is not neutral but it is not designed to pull to the left.

:'pretty much all modern VAG cars pulls to the left' is just plain wrong.

Just go and drive plenty to see that is not correct.

Take a flat surface and you can pretty much run cars up that with finger tip touching of the wheel lightly even brake in a straight line, holding the wheel lightly it should stop in a straight line if you a steering in a straight line.

If not find out why.

As 'sharkrider' says, 'cambers' and then its differing cambers.

Just with a vRS on 205' or 215's there can be different feelings.

VW, Audi, Seat put the cars out on 215's as standard. (try them on 225's or 235's and they feel different

Passanger weight, solo driver, luggage, full tank all differing weights in a car,

possibly 400-500 kg different Gross weight , cars cope with the difference between Kerb Weight & Gross Max load.

They do not pull to the left incase of Heart attacks.

VAG right hand drive cars actually drive quite well abroad without adjusting the steering or suspension.

vRS kerb weight 1243 kg, Total weight 1718kg. (Skoda Payload given as 475kg)

handling obviously slightly different loaded or just with driver.

Not that very different tho.

(Polo GTi on 215/40/17 is Kerb Weight 1269kg & Gross vehicle weight 1680kg, Payload 486kg.)

*remember Skoda fitted 25kg of (sand bagging weight) weight on the nearside rear crash bar of the hatchback, not the Estate,

you might even try removing this on a hatchback and find the car does not actually start heading for the other side of the road and head on collisions.*

vRS with weights removed is 1218 kg, 'kerb/unladen weight'

the vRS Estate 1238 kg

& Polo GTi is 1269kg Unladen.

Adjust tyre pressures to suit weight being carried.

Get tracking/alignment checked.

My vRS never pulled off a straight line until I put my summer wheels and tyres back on the car last spring. I then noticed a very slight pull to the left. I had swapped the positions of the tyres to even out tyre wear, which turned out to be a bad move. I decided to put them back in their original positions and this fixed the problem of pulling to the left. Experimenting with tyre positions on a car can correct minor pull problems assuming the tracking is not out. Note tyre directions when doing this.

This is why tyres can influence pull: -

Depending on how the belts are positioned during construction of a tyre (through normal variations in the manufacturing process) any deviation from nominal will allow the casing and the tyre tread to 'run out'. The disparities allow differences in compression amount over the tyre cross section from one tyre to the next which will determine its tendency to steer off a straight line, i.e. the amount of pull.

The manufacturer measures the degree of run out and marks the severity onto the tyre by the position of a coloured band, typically red or blue. If the colour band is central then the run out is considered zero, if the band is toward the outer edge the tyre will need a 'reactive' partner to counteract any pull. Runout stripes on the same side of both front tyres will make the car tend to pull in the direction of the stripe.

How much you can play around with this will depend whether your tyres are symmetrical in tread construction, asymmetrical or directional. In theory, when you buy new tyres, if you understand the markings you can obtain a balanced set, although most tyre centres won't know what you are on about if you ask them.

Lots of interesting stuff on the net or in libraries.

You should not need to be a Tyre Technician to buy and drive a car that runs straight and does not pull to the left.

Sometimes check the basics as the Owners Manual advises & if faulty set up on the car, expect those that are supposed to be trained and professional to get things right and sorted.

Then knowing more about it than them can just get passed of as having no relevance.

Knowledge of tyres, technology and principles or practices is good tho,

especially if you are starting to mess about trying to improve suspension and handling, and it is all rather important
