00016 'A' Camshaft Position Actuator Circuit/Open (Bank1)

[Ricey1]

A few weeks ago I changed the oil in my 200k km 2014 Tiguan, at the same time I replaced the Upper Timing Chain Cover Gasket 06H103483 and Timing Chain Cover Gasket for Magnet N91000101 as they were leaking oil. The car then had some sensor issue which I fixed by removing the oil filter and refitting the cable to the sensor behind it.
Yesterday it started to run terrible, after connecting the OBD scanner, I found it had a misfire on cylinder 1, when I removed the coil pack for cylinder 1 there was petrol in it and around the spark plug, so I replaced all the spark plugs and the car ran fine, then today I have the ECU light on, reading "00016 'A' Camshaft Position Actuator Circuit/Open (Bank1)", no other codes. I am wondering if I moved some cables in the process that are now throwing this error, the car drives fine.
Any recommendation on where to start?
