Hello, I have a 2006 bmw 330xi manual that won’t start or even crank.
The screen shows a yellow steering wheel lock and the ignition doesn’t turn on.
I installed a elv emulator but I hasn’t worked. I have used all of the different standard tools to try and reset or delete fault codes and elv counters. I replaced the battery because I thought it might be a voltage issue and that didn’t work either. Does anyone have any ideas what I can do or trouble shooting I can do?

Thanks!

I had an emulator on my 325 but the first one didn't work, returned it for a new one and it worked well, most of the time. They're not made by reputable electronics manufacturers so QA is questionable.

I just learned of a CAS coding option to bypass it entirely, no emulator needed:

I actually bought a second emulator and it also didn’t work. I tried coding the CAS to bypass the steering lock but I wasn’t able to connect to the CAS so I think that’s part of the problem.

Does the car have comfort access?

[treycullison57]

No it does not

Do you have A103 code?

It would help other posters help you if you would post the codes that you are attempting to clear that either won’t or reappear. The post is a little too vague to help.

I’m getting codes A0B2 and A0B5

If those are your only two codes, check fuses F4 & F51, both on the JB (Junction Box) Fuse Panel, beneath the glovebox. F51 is the 50-Amp large fuse on top row of large fuses, 1st fuse from left on that row if you do NOT have Active Steering. If you don't have a fuse chart, let us know.

Make/Model of your Scan Tool/ diagnostic software INPA/ISTA?

Hello I will check those fuses, I use a launch scanner with bmw license. And I have bmw standard tools on my laptop. I also have access to ista if needed.

Thanks!

[treycullison57]

Both fuses f4 and f50 tested good.

Connect the car to ISTA and carry out the guided troubleshooting for both of those fault codes.

[treycullison57]

Ok thanks

On a 2006 E90, F51 is the "Load" fuse. That's the one to check. If that is OK, then use INPA, BMW Factory-Level diagnostic
software, to assess CAS operation. See the attached INPA ScreenPrint, showing the Status of CAS Terminals. Also see the attached
pdf, INPA Tutorial Quickstart, for how to use INPA. The path, or Menu Sequence, to view that INPA Screen:
INPA > (Body | Car Access System) > F5 Status > F2 Analog > F1 Diagnose Terminals

If you will view, save & Post a ScreenPrint of that INPA Screen at each of these Ignition/Key positions, we can suggest "Next Steps:
1) Ignition ON;
2) Ignition OFF, but Remote Key still inserted;
3) Ignition ON; Brake Pressed along with START button (what you would press to Crank Starter);

The attached INPA ScreenPrints from my properly-functioning 328xi show:
a) Ignition OFF, immediately after Ignition ON;
b) Ignition ON;
c) START & Brake Pressed (Start & KL50 Active).

I've shown you mine; please show us YOURS

My ignition won’t even turn on

[treycullison57]

I will try and get this tomorrow after work

Is it your car?

[treycullison57]

Yes it’s mine

Perhaps I missed it, but I'm not sure from your posts to date whether the vehicle has EVER started during your ownership, or if so, WHEN the "No Crank" condition 1st occurred, or WHAT events (work/changes on vehicle) preceded the "NO Crank". Those facts would aid DIAGNOSIS.

If you have never used INPA, some explanation will speed your diagnosis:
1) CAS is powered by TWO fuses. On your 2006 model, those fuses are F4 & F51;

2) F4 is the 5-Amp "Electronics" fuse. Its voltage is shown on the INPA "Terminals" screen (mine was attached to post #14) as "KL30E", on Right of Top Row of bar graphs. If CAS were NOT getting power from that fuse, due to bad fuse or line fault, you would NOT be able to connect to CAS Module. 'KL' is German abbreviation for "Terminal" (Klemme, which can also mean 'clamp'). Folks who attempted translation from German to English chose "Ignition" in error. Google Translate, if used correctly, will give reasonable translations from technical German to Technical English:
https://translate.google.com/?sl=de&...e&op=translate

3) F51 is the 50-Amp "Load" fuse. It's voltage is shown on INPA "Terminals" screen, on Left of Top Row, as "KL30L". THAT is the first thing to check in your case. ISTA ScreenPrint showing location of F51 on 2006 Fuse Panel is attached. While a fault in CAS Module is possible, a fuse, wiring/line or Connector issue is more-statistically-likely.

4) You probably cannot connect to the CAS Module unless the Ignition is ON (START button pressed WITHOUT pressing Brake/Clutch). You say: "The screen shows a yellow steering wheel lock and the ignition doesn’t turn on." I don't have a "Nav" or CID Screen so am confused as to what 'Screen' you are referencing, or what does NOT happen when you attempt to turn ignition ON. On my 3/2007 build 328xi, when I insert Remote Key, press START button, WITHOUT pressing Brake/Clutch, the Instrument Cluster lights & "Ignition is ON". The INPA 'Terminals' screen shows KL15 ON. Terminal 15 is Ignition. There are 3 KL15 Bar Graphs: KL15-1, KL15-2 & KL15-3. There is also a KL15 Wakeup (WUP) Bar Graph.

5) KLR is the Terminal that SHOULD be activated by simply inserting the Remote Key in the Insert Compartment. When KLR is active, the Radio plays, the Brake lights operate, & the MRS module is powered.

6) KL30G is the Terminal that activates the accessory Relay, which is the large, black, removable relay on the right of the JB Fuse panel. When that relay is activated, Accessories, such as Climate Control Panel are powered. The panel lights & the blower motor functions. KL30G remains active for several minutes AFTER Ignition OFF, at least if Remote Key is NOT removed.

7) KL50 is the CAS Terminal that sends voltage to the Starter Solenoid, to Crank/Activate the Starter. If that signal is sent, but there is NO engine RPM per Crank Sensor signal to DME, an "A0B4" fault code is normally saved in CAS. You do NOT report that code.

8) You report 2 CAS faults, A0B2 & A0B5; BMW Fault Code Lookup provides the following definitions:
A0B2| CAS: Supply, terminal 30E/30L | cas | Car Access System
A0B5 | CAS: Fault, road speed signal | cas | Car Access System
https://bmwfault.codes/Lookup

There are other INPA Screens which can show you Signals received by CAS:
a) when Remote Key is inserted/removed;
b) when Brake Pedal is pressed (via Brake Light Switch);
c) when Clutch Pedal is pressed (via Clutch Switch);
d) when AT (if present) gear is "P" or "N".

If any of those required signals are not received, Starter may not crank. My 3/2007 build 328xi has the later EWS4 & NO Steering Lock, so I have NOT viewed INPA screens related to those two devices. While you MAY have an issue with the steering lock itself, the A0B2 fault appears to indicate a more fundamental issue/fault. I would encourage you to take the time to learn how to use INPA to understand exactly what signals your CAS module is or is NOT receiving.

Check your battery well and see if it's flooded with water. If no water, check the two tables at the bottom of them well for any corrosions. Check the fuses in power distribution unit (the red module on top of battery).

I had water flooded in the battery well for awhile and it corroded these two terminals. Both cables were completely severed. See link for photo:
https://www.e90post.com/forums/showthread.php?t=1803532

If everything checks out ok with no corrosion, then your CAS or DME could be toasted. It took me 4 months to troubleshoot CAS code A103 which wasn't the CAS module at all. It was the DME that failed due to water in the battery well.

[treycullison57]

I actually got a new battery cause I thought that was the problem. Didn’t work. I checked the cables and fuses everything checked out. I ended up sending me CAS and ECU to ECUPROs to hopefully get fixed. I will keep this thread updated when it returns

Thanks for everyone’s help!

[treycullison57]

So I made a mistake and the ECUPROS
said that there was nothing wrong with my CAS or ECU, so they are sending it back and I will have to figure out the problem still. I really though I had it figured out but I guess not
