Card tray to cup holder advice...

Its works with a bit of filing/cutting away at some parts of the cupholder - doesn't seem like an overly complication task.

I'm actually working on this myself after some great advice from the guys on ASN.

Hi Welshwoody,

The AUDI tech is sort of right. Both the cupholder and card tray mechanisms are the same width so they both fit. The problem comes when you try and replace the switch surround facia.
The cup holder facia (front bit with cup logo) is wider that your current card tray facia. Therefore you need to unclip the front off your existing card tray and clip that on to the cupholder mechanism. As mentioned by Pii, in step 4) of boggyms guide, you will have to trim down the side(s) of the cupholder mechanism to get the coin tray front to clip on properly.

It is a very good and easy mod on the pre face lift models.

You will also need to trim the back part of the cupholder see step 5) of boggyms guide.

Be thankfull you don't have a facelift model like mine - loads more trimming, way more difficult
but still worth it

Is your card tray by any chance illuminated? I would be interested in buying it , even without the fascia!
