There is no such thing as a K03s. There are a range of K03 turbos the later ones for 180bhp motors have a different compressor wheel and housing aswell as a stronger actuator, it is referred to as a "K03s" by the "scene". As far as I know all LC's with the AUQ engine have this model of turbo which is model no 5303-988-0052. You may see it referred to as a K03-052.

Your saying theres no such thing as the K03s but saying the parts are different from the earlier K03. That's like saying there no such thing as an R2 motorbike even tho the R1 has completely diffrent parts on it. I messaged a turbo dealer few days back and mentioned the K03/K03s and they new what it ment. The K03s has a smaller compressor and spools up sh.it loads faster than the K03. Two same turbos with diffrent parts.

Also all modles of the LC Auq dont have it. Under 2004 had the K03, over 2004 had the K03s

I direct you to this thread http://www.audi-sport.net/xf/threads/the-facts-about-the-k03-turbo.5970/ where Borg Warner confirmed to the chap there is no such thing as a K03s. I also had this discussion with a supplier when I replaced mine, as you said they knew fine well what I meant by a K03s but for the purposes of part numbers (which is what the OP wanted) it's unhelpful because none of the part numbers contain K03s. Just because everyone calls it something else, doesn't mean its true. Take the fabled Subaru "EJ20T" engine, that doesn't officially exist either, you get an EJ20 and you get a turbocharged EJ20 but it has never been officially called an EJ20T even though that's what everyone knows it as.

Also all modles of the LC Auq dont have it. Under 2004 had the K03, over 2004 had the K03s

I'm 99% sure all AUQs do have the "K03s", mine is an 03 and has one as did my friends 52 plate one and I haven't heard of one on here having anything but. There may be some older LCs with a non AUQ engine that have the older style turbo. The older model K03 turbo tends to be on Golf GTIs. The new ones came in long before 2004.

There's a couple of hybrids based on the ko3s turbo isn't there ? Do BBT not do one ? The path I was thinking of going rather than ko4
