Did mine yesterday, well worth doing, it's taken most of the excess movement out when in gear too. The most difficult part of the job was pulling off the gear lever knob.
Changed the gearbox oil while I was under there too - £18 per litre from BMW, which is pretty extortionate but at least it doesn't need doing often. Although the gearbox capacity is supposed to be 1.1 litres, it was full to the level plug with 1 litre added.
Already removed the CDV a couple of weeks ago.
