Yes, 2014 should be ok. I’m afraid I have no prior knowledge of coding on the Foxwell coder - only thing I can think of is that you need to enter the security code (31347) for the 09 central electric module to unlock it before coding on MQB cars (2013 onwards).
If you are based in NE England, then I’d be more than happy to assist with coding via VCDS.
I’m pretty certain that there are 2 different ways to code the rear lights as DRLs too - the way described above leaves the submarine lights in the front upper console on permanently too as far as I can remember - I coded this on an a Leon ST about 4 years ago, but then had to re-code each of the rear lights individually to stop this happening.
