This may help,

MJ2009 with BCM (03xx software)
Encoding   VCDS Byte 18 = 04
Lights go out at the tailgate opens   NO
Error message MFA   Rear fog lamp with Resistance: No
Problem with front parking light (weak light)   NO
LED tailgate light up more when braking   YES

MJ2010 with BCM from KW22/2009 (Software 0537, 0541)
Encoding   Halogen VCDS Byte 18 = 15   Xenon VCDS Byte 18 = 43
Lights go out at the tailgate opens   NO   Update on 0575 / 6 *
Error message MFA   NO   Update on 0575 / 6 *
Problem with front parking light (weak light)   NO   Update on 0575 / 6 *
LED tailgate light up more when braking   NO   Update on 0575 / 6 *

With MJ2010 / BCM 2011 from KW45/2009 (0573 & 0575 Software / 0576)
Encoding   Halogen VCDS Byte 18 = 15   Xenon VCDS Byte 18 = 43
Lights go out at the tailgate opens   YES   YES
Error message MFA   NO   NO
Problem with front parking light (weak light)   NO   NO
LED tailgate light up more when braking   NO   NO


I used 15 on mine with Halogen bulbs and using 04 gave me weak DRLs under normal circumstances and only full strength DRLs with side lights.

Thanks mustard, unfortunately still have the DRL warning light. Changing byte 18 to anything but 15 causes the rear light warnings to appear.

Someone must know how to sort this?

Right, so I've got the warning light out by telling the car it does not have DRLs installed.

This was done in byte 15 and unchecking bit 6. The DRL will only go on if you select the side lights or when the main beam is on.
