Audi A6 2.4 quattro issues?

[hallsie]

Hi guys and gals.

Im potentialy looking at buying an A6 2.4 quattro on a 2002 plate,
My question is,
Are there any obvious problems that i should be looking for?
I know there are issues on the RS4 and RS6 with suspension problems but did this extend to the model I am looking at?

Thanks in advance
