E70 4.8 2007, I’m hoping someone can lend some assistance. Replaced the valve cover gaskets. Seemed that all went well. It starts up and runs. I’m getting the following codes and don’t know where to look:

2a8b DME Inlet VANOS adaptation stop 2
2a8c DME exhaust Vanos adaptation stop
2b63 DME camshaft sensor exhaust
2b65 DME camshaft sensor 2 exhaust
2deb DME Power management vehicle electrical system
2E8c dme intelligent battery sensor, function
2eao dme oil condition sensor
2ebd dme no bad message from alternator
