Ah. Misread that then. Is there a suplex version of the sport spring.

My favourable comments on the FSI Sport's ride In OEM spec are based on 17" wheels. Wouldn't be a Sport otherwise!It also comes down to the condition or amount of wear that the suspension has endured. If a sport model's suspension has been renewed then it should drive lovely, as you say a tad firmer than the SE but fine.
In my opinion what affects the ride of the sport models more is the larger wheels (17") and therefore less tyre sidewall which greatly reduces comfort and making you feel every bump or imperfection in the road.
Added to this further is a lot of the earlier sport wheels were very soft and so liable to pot hole damage and becoming 'out of round' which a lot of owners are never aware of. This makes a huge difference!
Maybe these aren't the original springs. The standard front springs on the Audi A2 1.4 TDI without OSS have OEM part number 8Z0 411 105 AL.
Many of the springs in the audi.7zap.com "sports suspension" link are standard springs. These include OEM part numbers:Unfortunately this is misleading. There is not a single standard front spring for the A2 TDI without OSS, but rather a range of different springs, depending on precisely what equipment was fitted at the time of the original build. The only certain way to confirm the springs fitted from new is to ask an Audi dealer.
6Q0 411 105 AD was indeed one of the spring types fitted to A2s with sport suspension:

The spring, the damper, and the tyre are each single components, that together form the suspension assembly. They would, at the design stage, have been selected to be compatible with one another, and deliver the intended result.
Change one item in the assembly, and you change the characteristics of the whole, not always for the better. For example, change the wheel size (and so the tyre size) and the spring and damper are no longer correct The additional, undamped, compliance provided by the higher sidewall will reduce the force on the damped spring, and reduce suspension travel. So, you might get a softer ride, but it could be less controlled, as the undamped tyre is now providing more "suspension" So, maybe fit a softer spring, to regain the lost travel? Well, yes, but now the damper is going to be wrong ...

Many of the springs in the audi.7zap.com "sports suspension" link are standard springs. These include OEM part numbers:
8Z0411105AH
8Z0411105AJ
8Z0411105AL
8Z0411105AM
8Z0411105B
Fitting front springs with OEM part number 6Q0411105AD will increase the front ride height by 15mm compared to standard ride height springs, ie. 30mm higher than sports springs...assuming sports springs lower the ride height by 15mm compared to standard ride height springs.
You've spent a lot of time compiling all this information but seem to lack a fundamental understanding of how a spring works.
The degree of compression experienced by any spring is dependent on the load which it is supporting. Thus it's quite possible to use the same spring on a 1.4i SE and a TDI Sport, since the latter weighs more and compresses the spring further.
Far from raising the height of his A2 by 15mm over standard height springs, the 6Q0411105AD springs actually drop @Chiefmechanic 's FSI down to exactly the right height for sports suspension and are clearly correct.
Audi put a lot of time and effort into determining the best spring for any particular A2, and their recommendations certainly make a good starting point for any rebuild.
Fitting a soft front spring from a 1.4 petrol with OSS to a 1.4 diesel without OSS won't give you sports suspension. The ride height will drop, but you then have a soft ride that might be prone to bottoming. However, on a car like the Audi A2 that is not only light but originally quite stiffly sprung, you might get away with this lowering and softening of the ride.The degree of compression experienced by any spring is dependent on the load which it is supporting.

We don't know if the OP's car came with 6Q0411105AD front springs out of the factory. Many owners find sports springs too hard, and will have changed them to something softer.Audi put a lot of time and effort into determining the best spring for any particular A2, and their recommendations certainly make a good starting point for any rebuild.
Some nicely nuanced details there, do you have any similar front spring specs for the 1.4 tdi with OSS please?Three red dots and one blue dot is OEM part number 6Q0 411 105 AD. These were fitted to VW Polo 9N 1.2 petrol 54HP and 64HP engines and some Seat and Skoda cars.
6Q0 411 105 AD might not be the correct spring for the 1.4 TDI without OSS, as the specification is 11.25mm thickness and 357mm length. The specification of the standard front springs on the 1.4 TDI without OSS is 11.5mm thickness and 338mm length.

Also consider 6Q0 411 105 AC which are similar to 6Q0 411 105 AD except 15mm shorter, so the fitted ride height of the car with 6Q0 411 105 AC springs should be about the same as 8Z0 411 105 AL springs. The 6Q0 411 105 AC springs should give a slightly softer ride than the standard 8Z0 411 105 AL springs, as the coil spring thickness is 0.25mm less.

All three springs mentioned in this post have about the same number of coil turns, ie. about 5.5 coil turns.
See gknautomotive.com for their online catalogue. gknautomotive.com have a photo of each spring (so you can count the number of coil turns) and full specifications.
Some nicely nuanced details there, do you have any similar front spring specs for the 1.4TDI with OSS please?
That clears things up nicely, never realised that the available options were so numerous! Was going to go for a NAPA springs and Meyle shocks combination but armed with this info......Here are nine front springs to choose from (or add to a shortlist). They are all suitable for the 1.4TDI (with or without OSS) and 1.6FSI (with or without OSS). 6Q0411105AC has an 11.25mm wire diameter and 8Z0411105AL has an 11.5mm wire diameter, so 8Z0411105AL is about 5% stiffer than 6Q0411105AC.
Kilen and Lesjofors are the same springs made in the same factory in Sweden, just sold under two different brand names. So just purchase whichever is more widely available and cheaper, which is usually Kilen in the UK...if you want Kilen or Lesjofors.
I've linked to autodoc.co.uk because it's a good website for finding the model numbers of aftermarket parts. However, you can often find cheaper prices and quicker delivery on ebay.
