✅ BMW X3 M40i support

[jeff]

Thank you! Looking now.

[jeff]

What do you get when you run the command you found on the other forum?

Code: Select all

ATSH300
22F190

[jeff]

I've merged in 22F190 as the ODO pid in SHA: c53680d if you want to give that a try.

[sidbmw]

Still no data. Tried above command too and no data

[sidbmw]

Oh wait

[sidbmw]

Sent you the log. 01A6 in the terminal works but doesn’t show up under connectables. Good news is that 01A6 works

[sidbmw]

012F works in a new terminal as well. Battery voltage now shows up under connectables.

[jeff]

So in your logs it looks like the parameter support handshake in the most recent session is only returning parameters from ECU 7E1.

In the most recent session that you sent via email, was your car ignition off when you started the scan session?

Scan session where your car returned its VIN right away

One thing to test: make sure your ignition is on before connecting Sidecar to your scanner. Do you see your odometer parameter in this case?

[jeff]

So from what I can see in the logs, it looks like 01A6 is only returning values when the header/receive masks aren't set. So let's try a few more approaches:

No masking, new terminal session

This worked for you before, but let's confirm it's still working.

Code: Select all

01A6

New terminal session, just receive filtering

This should still work, because we're only filtering on the known receive address (7E8)

Code: Select all

ATCRA7E8
01A6

New terminal session, header + receive filtering

The first one should not work:

Code: Select all

ATSH7E0
ATCRA7E8
01A6

If the first two work and the third doesn't, then the BMW is not following the standard +8 offset practice and a different ECU needs to be targeted in order to speak to the Odometer. We can try brute forcing ECUs to see which one will talk to us:

New terminal session, brute force (copy all of these and paste at once to send it as a block)

Code: Select all

ATSH7E2
