New to the forum. Have just bought a 2009 A6 Avant SE, replacing a 2004 A4 Avant SE. The rear seat centre armrest in my A4 had a set of cup holders built in below the storage tray, however, my A6 does not, although it has a blanking plate that would indicate it is possible to retrofit cupholders. Is it possible and has anyone done it? I suspect the armrest is generic to the A6 and so presume it can be done to either a sedan or an Avant. I have had advice I need to replace the entire armrest. If so, it it an easy task? All assistance and advice gratefully received.
