I'm not sure what Mercedes has against cup holders, but they never seem to fit them as standard in their cars. This guide rectifies that and shows you how to buy and fit your own cup holder option. There are loads of ways of adding cup holders to a Mercedes, but this guide focusses on adding the correct OEM part that was offered as an option by Mercedes back when the car was first bought. OEM cup holders are much, much nicer that aftermarket solutions so why anyone would fit anything else to an S Class is beyond me. Anyway while fitting is easy (as nothing needs to be unscrewed), sourcing the correct part is less easy (unless you have the code from EPC). You'll find loads of OEM cup holders on EBay and the like, but unless you know this code you risk purchasing ones that will not fit.

This varient fits cars from 2009 until the W221 model ended in 2013. The part number is A2218130014 and it can be easily distinguished from the earlier model because of its lock button on the top, full depth sides and lack of a retracting lever on the top (see photo to left and compare with those in previous sections).
