[Solved] BMW PIDs
on: July 30, 2015 (GMT)

The mistery is solved

N47 (2007-2009 Diesel Engines)

Vehicle profile ELM327 config:

AT PB E1 01\nAT CRA 612\nAT SH 6F1\nAT FC SH 6F1\nAT FC SD 12 30 0F 02\nAT FC SM1\nAT CEA 12\nAT CM 600\nAT H1\nAT SP B\nAT BI

Most useful PIDs:

Oil Temp: 2C100458 –> °C : B
Oil Age: 2C10044C –> KM : B and C
Oil Level avg: 2C10044D –> % : B [calculation unclear]
Oil Level: 2C10044E –> see “Oil Level avg”
Engine Temp: 2C100AF1 –> °C : B
Mileage: 2C1005DD –> KM : B
Fuel Level: 2C100384 –> L : B

**NOTE: “A” is not suitable because the result is always lead by 6C10

(I’m currently working out the adaption values to reflect the actual result. Stay tuned!)

Re: [Research] BMW PIDs
on: August 18, 2015 (GMT)

I’m digging this up because through some additional research I was able to understand the stuff which is happening before – vital stuff I thought was unnecessary.

– The device filters for responses by device 612 (ECU)
– …and filters for responses with header 6F1
– It sets up for the extended address 12

So..
-> It knows out of the box that it needs to talk to “6F1” in order to reach “612” where all the magic is at.
The extended address is “12”

I tried all of the combinations (6f1 as header, 6f12c, 2c,12,…everything) but couldn’t manage to get any response.

Any ideas?

//EDIT as it seems torque needs to be modified to be able to send out 8-byte long PIDs because of the D-CAN protocol and BMW special language inside the ISO15765-2 standard and extended addressing. Although Torque is made to support custom PIDs it isn’t fully prepared for stuff like this.

A full request to the ECU would sound like this on the terminal:

6F1 12 04 2C 10 04 4D

The response would be

612 2F 10 03 6C 10 F4

The shortened variant using headers and filters is just “2C 10 04 4D” for the oil temperature.

Torque doesn’t seem to support this kind of message format at the time or I don’t understand where to put what.

I managed to set up the right ELM configuration to enable the support but unfortunately it isn’t possible to use the PIDs as display source since the PIDs can’t be larger than 6 bytes.

Here you go. This is the key into the extended PIDs for BMW e-Series type of ECU (2007+):

AT PB E1 01
AT CRA 612
AT SH 6F1
AT FC SH 6F1
AT FC SD 12 30 0F 02
AT FC SM1
AT CEA 12
AT CM 600
AT H1
AT SP B
AT BI

–> Enter this in your vehicle profile:

AT PB E1 01\nAT CRA 612\nAT SH 6F1\nAT FC SH 6F1\nAT FC SD 12 30 0F 02\nAT FC SM1\nAT CEA 12\nAT CM 600\nAT H1\nAT SP B\nAT BI

Now if you create a new “Send Command” button on your dashboard and enter “2C10044D” and press “Test Command” it succeeds and returns the value.

If only Torque would be able to send “overlength” PIDs, that would be great… 😉

…awww this is great!
I’d be glad to beta-test it, as soon as it’s ready 😉

In the meantime I’ll go and fetch the other PIDs and post them here.

Oil Level:
Command: 6F1 12 04 2C 10 04 58
Response: 612 F1 04 6C 10 31 2E

Can you give us an answer in the terminal to such a request for Engine:
Command: 6F1 12 02 1A 80

and 6F1 12 04 18 02 FF FF

thank

Re: [Research] BMW PIDs

21A80 for the first one.

I’m sorry I can’t test this whole stuff at the moment because my precious toy was inflicted in an accident and is undergoing some cosmetic repairs at the moment…

So no guarantee on validity this time, I’m afraid

This is all header related. you need to enter the whole 8-byte string in order to get the value for the second one. This is (as far as i know) currently not supported by torque but is on the todo list (see previous post by piemmm)

For the second PID it’ll be the last 8: 18 02 FF FF
You need to specify the BMW specific header AND configuration in order to receive any data from the ECU because this mode is only meant to be triggered by official diagnostic devices!

So your first PID isn’t exactly on that super secret address room and should be readable by just entering the config I wrote before.

Just to explain what is happening, i’ll go further on and show you how the “overlength d-can” PID is thrown together:
first byte: 18 – device address
second: 02 – mode
third: actual 4-byte PID which encapsulates the module.

You might have noticed that the oil related stuff sits on the same address and this is because the sensor(s) which measure pressures, temperature, quality and level are sitting in the same compartment inside the oil sump and resemble a single device on the network.

So if you look at the whole thing: 2C 10 04 58
we are addressing on extended address 2C on mode 10 at device address 04 for the PID 58.

D-CAN, because CAN alone wasn’t complicated enough. duh.

It is not very clear
take a few examples in the terminal
I am not for Torquay I write emulator
If you can link about this protocol D-CAN

Re: [Research] BMW PIDs

It really is a “slang” of the original protocol and just uses up to 8 byte as a request. That’s all the magic, combined with the special ELM config.
I can’t post the whole communication as an example since I fear someone might trace it down.

We’re speaking of tapping licensed equipment which normally costs about 10000€

HINT: use the config I posted earlier. Without it won’t work…

Re: [Research] BMW PIDs

I do not need the whole answer, need to know the the first 4 bytes of response
you mentioned two examples, different answers, I’m confuses

Re: [Research] BMW PIDs
on: December 3, 2015 (GMT)

ah well – this is easy. It usually starts at the 6th byte in this response (not counting the header 612):

FF FF

Re: [Research] BMW PIDs

I, again, completely misunderstood your question. Sorry for that!

1st) 6F1 12 02 1A 80
2nd) 6F1 12 04 18 02 FF FF

These are both requests, right? I really don’t know what these two would output and I am not eager to send any unknown commands to my ECU to test them. The only thing I know is that the second one belongs to the engine family (04 prefix).

Maybe I will stumble upon the codes when checking out the remaining functions and PIDs. I’ll let you know then…

Re: [Research] BMW PIDs

6F1 12 04 18 02 FF FF
6F1 –
12 –
04 – the number of bytes in the command
18 02 FF FF – command read errors

1A 80 – request for information on the block

but if you are afraid of, then yes, is not worth
Thank you.

If this is designed to request error codes then I will try to log the whole error code procedure of the device. I might have access to it again in January.

Re: [Research] BMW PIDs

UPDATE:
Instead of going through the tedious process of sniffing on the wire, I cracked the database open and the result is a spreadsheet with pretty much any PID available including description (in German only but that shouldn’t be a problem…).

Now it’s only about testing them and trying to figure out how the return values are formatted, which of course is only possible as soon as the app has been updated.

Stay tuned.

I found a thread on E46 Fanatics and this is what I was told is the oil temperature PID

EDIT – It is lot letting me post the code so I will spell it.
(Dollar sign)01 0x5c

I have to be completely honest, I do not have a clue if that is correct or even a PID format. Lets assume it is accurate. How do you use that information to start logging oil temperature?

I have Torque Pro and use it mainly in a street legal 2003 BMW 330i that sees most of its miles on the race track.

Re: [Research] BMW PIDs

it’s probably this:
Engine Oil Temperature: 0x5822 -> 5822 [adaption: -40, factor: 1, °C]
or
Oil Sensor: 0x4408 -> 4408 [no adaption, factor 0.1, °C]
