Alright so where do I begin… I bought a BMW.. lol I have a 2007 BMW 328i and started running into issues where the car would not start, I'll get a crank intermediately but then the starter locks up. So I started doing some research on diagnosing the car and found out about INPA and ISTA. I manage to download ISTA+ and diaged the car and I am getting issues with the DME and CAS when I try to do a CAS alignment I get an error saying

"It was not possible to determine any basic features from the vehicle.
The central encoding key (ZCS) or the vehicle order (FA) is invalid or not entered. In this case, the central encoding key or vehicle order must be subsequently entered via the encoding/programming function.
There may also be a fault in communication with the control units. In this case,
troubleshooting must be carried out on the vehicle."

I've hit a bit of a wall, I'm trying to figure out what to do now and would like some help if possible. Thank you

FA can be entered through NCS Expert

Whatever your problem is, I doubt very much it has anything to do with DME-CAS alignment.

CAS will activate the starter and keep it activated regardless of the alignment state (as long as the correct key fob is used). If the modules are not aligned, the DME will not let the engine fire but the starter will continue to turn. The starter will never "lock up".

Why don't you start by posting whatever fault codes you observe?

So that’s what’s happening, the starter will crank but no complete turn over.

Sorry, not at all sure what that sentence means.

Also, post the error codes

I mean when im trying to start the car all I get is a crank. the engine does not completely turn on. and here are the codes that I got from INPA.

00 JBBF MNO ERROR
01 MRS NO ERROR
12 DME/DDE ERROR 2E7C
12 EKP NO ERROR
20 RDC NO ERROR
27 PGS NO ERROR
29 DSC ERROR 5DE0
37 AMP NO ERROR
40 CAS ERROR A0B4
56 FZD NO ERROR
60 KOMBI NO ERROR
62 MOSTGW ERROR E18F
63 MASK/CCC NO ERROR
6D FAS NO ERROR
6E BFS NO ERROR
72 FRM ERROR 9CCE
78 KLIMA NO ERROR

Thank you

I'll assume you have a manual trans since no EGS module is detected.

9CCE means the battery has been deeply discharged at some point. That will permanently reduce the capacity of the battery to some extent

5DE0 means you have or had at one point a fault speed sensor on a front wheel

E18F is some sort of MOST bus error - irrelevant to the engine.

27EC is a BSD bus error. If that is current it will set the check engine light. However, it will not prevent the car from starting

A0B4 means that CAS has tried to activate terminal KL50 but the current being drawn is out of range. In other words, CAS is applying 12v to the lead to the solenoid - the small diameter white single wire that you see going to the starter. However, the current/voltage being drawn is below or above spec.


The simplest explanation for your issue is a dying starter/solenoid. Not the only one but the most likely one. Easy enough to test - you'll just have to expose the starter (remove airbox, intake manifold) to get a jumper cable in there.

So the battery is due to me changing out the old one. I do believe the starter is an issue and was faulty from when I purchased it but at the time I did I was still able to turn on. When I get inside of the car and attempt to start it first time around, the starter works fine and the car cranks but no engine start. Also when I am using ISTA the DME and the CAS are yellow if that means anything to you.

Yes, it means you have errors stored in DME and CAS. Yellow is communicating but has errors, red is not communicating.

I'm still confused by your descriptions. What do you mean "first time around"? Are you now saying the starter turns the engine over normally but the engine does not fire?

In the future, take screen shots from ISTA and INPA and post them

Going back to this sentence, what does "not completely turn on" mean? Does that mean there are signs or sounds of ignition but the engine does not actually start running? What does " all I get is a crank" mean? All you get is one revolution of the crankshaft?

Perhaps post a youtube video of you trying to start your car.

Ok so it seems like the "lock up" of the starter seemed to be that the battery didnt have enough to start it. i got my hands on a battery charger, fully charged the batt and the starter kicks every time and turns the engine but its not firing on. i have a video of me attempting to start it. i have also tried to clear out the faults within the DME and CAS and they are still showing yellow.

And the only DME and CAS faults you see using INPA and ISTA at this point are 27EC and A0B4?

[dpaul]

What engine do you have?

[dpaul]

Manual trans?

Yes those are the only 2 codes pertaining the CAS and the DME. I have a N52 and manual trans

Did you ever figure this out? I am having the exact same problem and don't know what to do and I've tried almost everything.
