has it got the k03 or the k03s in it as standard ?:1zhelp:, is it the k03 that can safely be modded up to 220bhp, or is the k03s that has its safe limit on 220 ?

if you are a facelift A3 then you have the Ko3s which can be maped to to around about 220bhp

facelift was in 2000. new a3 8p's came out in 2003. im pretty sure you have the k03s. i believe the a3 quattros are engine code AUQ an they came with the k03s 100%.

tish, you will have a k03s. ARY engine code is k03s also. i have only just noticed there are 4 different 180bhp engines. ARY, APP, AUQ and AJQ! no idea what the differences are though.

20vtel, Cheers for that mate, mine is the 150bhp engine so would it still be the ko3s turbo?? if so, thats good news as i am about to get it re-mapped.

i think all the 150bhp engines on a x plate or later were k03s. im guessing your engine code is AUM which would almost certainly be a k03s. you can check yourself but its a little hard to see. behind the engine you will see the turbo. on the intake side of it there will be a little blue plate with numbers on. It should say k03-052, k03-053 or k03-058. if it doesnt have these numbers then your turbo will be the k03 and not the k03s.

i will be selling my k03s turbo soon as im goin for an eliminator big turbo kit. if it turns out you have the k03 turbo i will be selling mine cheap if your interested?

hope that helps.

Spot on mate, really appriciate your advice and knowledge. i will have a look tomorrow in the day at my turbo to see if there are any numbers on it. will let you know how i get on with it.
Yeah mine is an AUM engine.

Have you had much done to your engine and have you had a dump valve on it??

Nice 1 mate
