which gearbox ?

It will be on the printed data sticker in your car, usually stuck in the boot I believe and on your handbook/service book.

I thinks its DES you want this for elsawin dont you. i had the same prob. i used this and then selected the sedam a6 2.4 in the more box. this then gave me all the info. i think the engine info is AGA.

But it does make sense now.

I think mines the same then as it does not have secondary air system all the later models have this.

you look to have a choice of three - DWK DWP or EAA

have a look at your sticker - you should see one of these
