Elec tailgate failing to open / close, clicking noise, opens 5/6 inches only. Similar to other posts. Found on Ateca forum that wires inside the rubber grommet on RH side above the strut, had snapped , looked at mine and one had snapped, one was about to, faffed about trying to loosen roof lining at rear, gave up. Cut the rubber convoluted tubing and soldered the broken wires together. Bit awkward but possible with care and a small soldering iron, tried it and it worked. Other posts have said it cost approx £400 to repair! Try this before visiting dealer. I had to rubber glue the tube together but managed it with some tie wraps. Will add pics.
