Changed the oil filter insert was fine

Had fault codes 130716 p1523 p13c9 changed oil filter and Vanos actuator on exhaust side cleared codes drove for about 30 miles parked overnight then engine light came back while driving to work. I keep clearing the code p13c9 as that’s the only code showing on my reader ( cheap one) going to do an oil change then look at changing the camshaft sensor anyone came across this??
