CEL Code Help

Just thought I'd post on here to get some additional help aside from my own diagnostics. If anyone is keeping up with my build thread I am rebuilding my z4m roadster from the dead. There are 10 cel codes so bare with me. The car will be going to the shop soon but i prefer to figure some things out myself if possible and save money one labor and repair cost. thanks in advance.

1) p0072 - Temp. Sensor - says low input.

2) p1644 unsure

3)p0113 intake temp sensor - hight input. I assume the maf needs to be clean or a new one needs to be replace? I do have a cone filter and not oem.

4) p120D - unsure

5) p0140 - 02 sensor circuit not activated - o2's are dead or needs cleaning?

6) p2185 - coolant temp sensor 2 circuit hight

7) p0013 exhaust b camshft position actuator - Bank 1

8) p0010 Intake camshft actuator circuit open bank 1

9)p0140 - 02 sensor circuit no sensor (dead o2 prob or needs to be check)

I'll take the easy one

Ambient air sensor is under the left side of the front bumper.
It's a little probe sticking out of a hole in the left side plastic box near the bumper fang.

I haven't seen your build thread but for starters have you checked all the fuses in the DME?

Pretty sure sensors at the rear end of the camshafts.

Parts #3 and #8 sense parts #13 and #15 spinning around.

But you said the codes were for actuators, which sound more like a Vanos problem.

I'm assuming from the "P" codes that you're using a generic OBD scan tool.
You may want to get set up with a GT1 knockoff so you can run DIS and get some better diagnostics.
