Hi, my 2020 A4 Avant power tailgate is no longer lifting or closing. The lock triggers but the power tailgate makes no noise or no attempt to lift. Can open manually but can't get to the garage until end of May. Any advice in what the issue could be and how I could fix this myself?

 

Thanks 

Hello Warren,

Thanks for being in touch.

Worth peeling back the covering of the flexible harness section between the body and the tailgate, and inspecting the wires. Favourite spot for wires to break due to flexing when opening and closing the tailgate - particularly following cold weather.

Perhaps you would let us know how you get on. 
Kind regards,

Gareth. 

All the looms look intact with no issues?

Have you checked the fuses. With the retractable cover stuck too that sounds like no electrical power to it.

in failing that it could be the motor. If it's the foot operated one then maybe the sensor has failed. 

Also there are 2 boot latch control modules that need to be replaced as a set (pair) but I don't think this is a common failure. Maybe you just have a flaky switch or loose connection. Did you check the wiring into the switch? Or try to spray electric switch or contact cleaner into the switch itself? Could just be a dying switch. 

also the boot struts can fail too. 

Hi Warren, I have encountered the same problem. Did you find a fix and if so what was it, please?
