Would anyone no if the wheel arches on the Audi allroad A4 are wider than other Audi arches on the A4 . I've nothing to compare to 🤣

Yep they are. Unpainted plastic. 

So are the arches on the allroad wider than stock Audi arches on a non sport model. The allroad arches look like they come off? 

They're wider. I believe the allroad wings are different so the arches can mount to them. 

Interesting to no . I like the allroad a lot can be done with the bi turbo. It's just the air suspension let's it down 👎

I think you'll find the A4 allroad actually has coil springs. Think air suspension is an option on them. The a6 allroad has air suspension. 

That's something I didn't no . So I could just fit factory suspension in its place . Is there any documentation that says that? I'm in new Zealand and my Allroad is a jap import on air suspension. Out of interest do you no what turbo chargers came on the bi turbo. Some people say k03 some k03s and some say k04?

Yea air suspension can be changed for coils etc. Even some aftermarket kits are available.
