Camshaft adjustment after timing belt change without function C4 VTS 177 HP EW10J4S RFK engine

Hi. I changed the timing belt in my own direction. Engine runs and starts well but on top he pulled from 6000. He doesn’t do that anymore. Think the cam adjustment doesn’t start any more. I’ve done very hard to find the sockets of the camshaft. I hit a point on the left on about 19/20 clock. A passagehole. Right also at about 19/20 clock. Since the sockets are always symmetrical on the Internet, that surprised me. Can someone with the P Or does anyone have an idea what might have gone wrong?
