Polo rline 6R factory xenon upgraded to 6C no side led lights fault

Hope this is ok to post as I’m pulling my hair out here;

I have a Vw polo 1.2 tsi 6R R-line polo 2013 with factory xenon’s But fitted polo 6C bi-xenon with LED’s (genuine) 2015 headlights
But the parking/side lights only come on for 2 seconds then off, everything else fine.
It has fault codes: 

02896
Activation for Left LED Parking
Lamp/DRL Module-Short circuit to ground

02898
Activation for Right LED Parking
Lamp/DRL Module-Short circuit to ground

00446
Function limitation due to insufficient 
votage-Lower limit not reached

BCM
7H0 937 089F

Is the BCM ok to activate the LED side lights? 
The pins are all there which are not in the basic models and all worked fine with the 2013 xenon/led headlights 

Point of note, I have had the later (6c) rear lamps in for about 3 years without any fuss, some forums suggested there isn’t enough power reaching the LED headlight because of the later rear lamps?? 

I don’t have access to VAGCOM or anything similar so if it’s is just a case of coding the BCM would anyone be able to sort it???
Or point me in the right direction 👍🏼👍🏼

Apologies if this is totally of group topic!!
