Welcome to the Forum!

Please complete the year, model & engine of your vehicle in "mein auto", e.g. "2008 335i E90 N54." It is also helpful to add build date MM/YYYY as fuses and other electrical circuit matters are dependent upon build date, and changes occur during model run. Any circuit information below assumes 2008 or later 335i with N54 engine.

You have codes for:
1) Exhaust Camshaft Sensor Signal out of limits (2A9B),
2) Communication Fault between DME & Coolant Pump (2E84)
3) Multiple occurrences of Signal Fault, Ambient Air Temp (2F9A)

The code related to crank but NO start (no fire or sputter at all during cranking) is 2A9B. If the DME (MSD80) does NOT receive a Cam Timing signal from the Exhaust Camshaft Sensor during starter cranking, it (the DME) CANNOT time the spark and/or injector pulse, so you have NO spark and probably NO fuel to the cylinders.

I would disconnect the Connector to the Exhaust Camshaft Sensor and clean the pin/socket with Electrical Contact Cleaner, carefully inspect the wiring, make sure your battery is charged, and try, try again.

Here is the TIS circuit diagram for the "Valve Gear" on 2008 & later N54, and also the "Installation Location" of the Exhaust Camshaft Sensor (B6224a):

There is MORE information saved in DME memory than you have provided (you're holding out on us ;-) The page you attached is DME | F4 | F1, Read Fault Memory or "Fehlerspeicher Lesen." Please reconnect INPA, and select DME | F4 | F3, Fehlerspeicher Lesen Freeze Frame. You will get a screen similar to the attached for EACH Fault Code (multiple screens). If you could create a jpg file of each "Freeze Frame" screen related to Camshaft Sensor Signal Fault (2A9B), and answer the questions below, we can get a better idea of whether the Camshaft Sensor should be replaced. Saving a screen as described below is MUCH better than taking a photo of your computer screen, is quicker, and avoids forum eye strain.

IMPORTANT TRICK: You can save ANY screen in INPA for future reference, OR to attach to a post here for help/translation:
0) Before opening INPA, or with INPA running in background, Open Paint or photo editor of choice;
1) In INPA, Press Shft+PrtSc to save the desired screen in working memory (one screen at time);
2) Paste (Ctrl+V) INPA screen to Paint;
3) SaveAs "jpg" file in folder of your choice.

I have saved sample screens of most INPA functions that way in a "Tutorial" Folder so I can quickly see exactly what information is available from each of the ~ 20 Modules in the vehicle, and you can at least save fault history for each module this way. Google Translate is fairly good at translating technical German, and I would recommend trying that a few times. You may be surprised how quickly you learn the basic terms and terms that are repeated often, such as "Fault currently exists" (or is present), or Fault would NOT light a warning lamp (MIL). See translations below.

It would be helpful to know the following:
1) When did your car last start normally?
2) What if anything was done under the hood since the car last started normally?
3) Any recent part failures or repairs, and if so, what & when (such as serpentine belt failure & replacement)?
4) What mileage is NOW shown on the odometer?

fehler momentan vorhanden, noch nicht OBD-entprellt = error currently exists, not yet OBD-debounced
Fehler verursacht kein Aufleuchten der Warnlampe = Fault would NOT light warning lamp (MIL)
kurbelwelle - auslassnockenwelle, synchronisation = Crankshaft – Exhaust Camshaft synchronization
Nockenwellen signal außerhalb Grenzwert = Camshaft Signal out of limit
Kommunikation mit kühlmittelpumpe fehlerhaft = Communication with Coolant Pump faulty
