Headlight problem. Please help :(

[TheManGaz]

Hi and thank you for taking the time to look at this.

I have an A3 1.6 Tdi 2014. I have replaced the dipped bulbs and one of the main beam bulbs but then my issue started.

The main beams are H15 bulbs. The bulb, as you might well know goes in and twist into the power connector but that connector has come away on mine. It seems a real fiddle to clip it back in and believe me I have tried. 

Can anyone help? Do I need to take the headlight unit out to do it and does anyone have any diagrams on how this is done? I'm capable with a screwdriver and spanner etc but having not done this before I'd like some insight on how it's done.

Any help would be greatly appreciated.

Regards

Gary
