My car is a march 2003, DE78215, and I have successfully replaced the original TCU, which would be the same as your one now, with the facelift Bluetooth version TCU.
I did not try Bluetooth with my pre-facelift (original MMI). One of the first things I replaced in my car was the MMI with the facelift one.....more colours, better graphics and faster processing.
So, if your inclined, it can all be done.
If you need help with the diagrams just let me know and I will help as much as I can.
The ringtone is much better in the car too with the Bluetooth set up by the way......

Hi Ace,

Thanks very much for the reply, thats great news!

I will take the panel off and see which pins in the connector are occupied so i know which diagram i should be looking at!

I understand I will need a bluetooth antenna fitted under the arm rest that is wired directly to the new TCU, is that correct? does the TCU need any coding itself? or is it pretty much plug and play? (with the exception of the MMI coding of course).

One last thing! im sure you have covered this before so I apologise in advance!, exactly what software and interface are you using to code the MMI? I may have looked it up before and it was pretty expensive, can the same coding be done with NCS expert?

Thanks again!
