If you have a mk 6 GOLF, then chance are you already have an armrest. Some models, like the 1.4 TSI S (122ps) , and others do not have them as standard.
My local VW dealer quoted £622 fitted........
I picked mine up on Ebay, for £70. It was missing the aux in and the media connects, but otherwise it was in perfect condition .
It might be helpful to describe the fitting process.
You will need a size 20 torx driver, and I used a flat bladed driver to 'open up' gently.
1).Firstly separate the inner cage of the rest from the body. The body is in two parts.(sides and back) .
2).Remove the existing piece of console to the REAR of the handbrake. (Nothing else needs removing).
There are 3 screws, one is obvious, the other two are hidden under the non-slip mat in the rear cup / bottle holder.
3).Offer up the armrest cage, ( pull handbrake lever up as high as possible), sliding the cage over the Brake lever,and you will find the cage sits perfectly in place.( I needed to remove the air venting from the cage supplying the rear vents in armrest, in order to facilitate this. Otherwise I think the lower front bit of console needs to come off as well).
4).There are five obvious screw mounts/holes, and these were sufficient to make armrest rock solid. I used the three from the removed piece of console plus two more torx screws.( this way still only one tool needed).
5). Once the cage is set firm you can slide the outer side casing over the cage. It has its own clips inbuilt. Surprisingly fitted perfectly and firmly.
6). I had slightly more trouble with the last piece of kit, the rear outer casing , housing the two cup holders,(ingenious) and rear air vents. I found it was easier by removing the cup holder block, offering up the remainder of the casing, which again has its own built in clips, and then replacing the cup holder block. It fitted again, perfectly. That was it. 40 mins tops.
NOTES.
I HAVE A PERFECTLY GOOD OEM ARM REST NOW, THAT LOOKS PLUSH, AND FUNCTIONS BEAUTIFULLY. IT LACKS THE AUX-in (Which I will replace shortly), and the air vents don't work, ( no air supply). It also has an inner compartment for a CD changer or multi media tray, which I may or may not utilise.
It transforms the S models interior, and all for £60 .
You could do it better than me, by utilising the removed air trunking, but it is a bigger job.
I want to replace the basic radio now with a double din model, but that's for another day.
