Q5 Faulty DRL

A little while ago the drivers side DRL on our 2014 Q5 decided to die. Vcds throws up the 02897 code, supply voltage to led DRL module. The warning pops up on the dis with the ignition on. I disabled the DRLs via the mmi which stops the warning unless you have the lights in auto or turn them on manually.

If you turn them on manually there is a flash then it goes out. Then the warning pops up. I did some digging and a blown fuse or a faulty DRL module is the culprit.
I checked the fuses and none seem bad and I looked in the manual and none seem to be assigned to the drl anyway. Just the headlight in particular and as that still operates on low/high beam I assume that fuse to be fine.
So I moved onto the module. Purchased a new one from Audi, plugged in, flicked the switch, and the same thing happens. Light flashes on for a second, then goes out. Warning pops up on dash.

Question is what else is there to check? The wiring around the immediate area looks in good condition so I don't suspect that. I have exhausted Google and apart from purchasing a replacement headlight I can't see what else to look for.

Any links or advice will be greatly appreciated

As mentioned on your FB post, chances are if you have a new module from Audi that it will need coding. New modules are “virgin” with no coding or parameters loaded and will need a VAG specialist to configure them, and also calibrate if needed.

So I thought I'd sorted this until today. After fitting the new module I cleared the faults and had a look to see if anything was out of place but still didn't work. I left it as it was getting late. Went out the following day and it started working and has been working fine ever since. That was until this morning. Got the warning light and the bulb is out again. This I'm assuming is now an issue elsewhere? Bad earth as suggested? Or is it coding? Which wouldn't make sense as it has been working 'plug and play' without any coding changes. Any suggestions? Cheers
