E39 523i not starting.

[gizmo10]

Hey! I took my 523i for a spin a week ago and it worked perfectly fine. After driving, I parked it and now a week later it won't start.

The fuel pump is working and there is fuel in the car. Sometimes it wants to fire up but then stops so I assume there is spark..

Today I read the fault codes and got plenty of them...

AA - Control module self-test 1 implausibilisation
AB - Throttle control valve
6E - Accelerator pedal sensor 1
70 - Signal throttle sensor potetiometer 1
73 - Adaption 1, engine throttle
15 - VANOS solenoid valve inlet
13 - VANOS solenoid valve exhaust
53 - Unknown
27 - Unknown

About a month ago I changed spark plugs, Intake cam sensor and the crank sensor.

Anyone that can help me diagnose the problem will be my HERO!

6E may be the culprit, which requires replacing the throttle pedal assembly.

AA, AB, 70, and 73 may be the result of 6E.

13 and 15: make sure you have coil continuity and B+ at the VANOS connectors.

What is the battery voltage, engine stopped? Should be 12.5+.
