Hello everyone, i have removed the engine along with the gearbox to change Timing chains. I also changed oil pump. After we put the engine with the gearbox back on we are trying to start the car but it wont start but makes 2-3 sounds like its going to start then immediately shows engine power reduced on the screen and doesnt make the sound again. Also idrive controller CIC type doesnt work along with the buttons around it but everything else on the radio works. The only error that i constantly keep getting inside the car is brake pads replace which wont go off. I reset them through the dashboard and also through the obd and they wont go off. I think we might have missplaced a grounding or a power cable because the errors we are getting are mostly for throttle valve which we replaced and didnt have any effect. Any help is appreciated
Update: I get this codes in obd: I get
4DF9
4000
4D87
3F01
4390
5DE1 DSC
5DE0 DSC
Also when i clear them only 4DF9 remains throttle valve actuator position sensor signal
