Hello,

i'm new to X5/X6 platform, but I've been driving BMWs for 15 years so I know basic maintenance. Recently I've bought a 2014 f16 35i N55 with CEL. It has 2 codes:
-valvetronic relay activation; line disconnection
-valvetronic supply voltage; line disconnection

the car drives, starts, pulls ok and has plenty of power. I've checked voltage on the module PN 12638645514 and the valvetronic section showed 0 volts. So I ordered new one from the dealership, switched and nothing changed. Now I don't know if both modules went bad or do I have to check something else. Maybe there is something to look at before I buy new servomotor and another module? Maybe DME is faulty? When I pulled out the plug from the servomotor, it threw other codes as well. I'm at loss and I will be very grateful if somebody could help me with this issue.
