due to cracking my front undertray badly im in need of another, i have looked on Etka and can't find the part number for it to see what others fit,

mine is a 2007 B7 saloon, can anyone help with the part number or a identical one that will fit off another Audi??

thanks very much!

You'll need the RS specific one if you want to retain the brake cooling vents. It looks a bit different to other B7 models.



As I understand it, there are 2 types of plastic undertray; original 8E0863821AS, and 8E0863821AT is a revised/heavier duty version.

Have you considered upgrading to an aluminium one?

thanks for all the details buddy, i did remember reading that thread before but forgot that was in there,

how much was the aluminium undertray if you dont mind me asking ??

cheers

I've seen there are a few options of alloy undertrays, but for A4 and S4, so not the porper cut outs for the RS4 cooling

If anybody knows of one other wise please give us a link or pic

Ah - I never replied to this!

I believe JCWF are retailing the custom made ali RS4 tray for £650. (Link in my last reply)
