So I popped down to my local MB dealer to try and acquire the rear diffuser to replace my single exit sport pack diffuser. I left £90 lighter with what I thought was the correct item. It was part number: A 204 885 39 38 It seemed to cheap to be the right one and turns out it's the one for the facelift I think. Does anyone know the correct part number for the pre-facelift as they couldn't find it at the parts department? Either that or does anyone have a good aftermarket part recommendation for a twin-exit rear diffuser to fit pre-facelift?
