Here you can find the specifications for OSEK-NWM. Derived from that is the VW NWM, and the differences are very small and recognizable even to a layperson .



Integrating all of that into can tool doesn't really make sense, since each manufacturer uses a slightly different Network Management (NWM) system.http://portal.osek-vdx.org/index.php?option=com_content&task=view&id=9&Itemid=13{MARKER}

Okay, thank you. I'm just going to browse around there.

So, network management is actually relatively easy. Is a 'circle' of news items associated with a few status bits.

These are the IDs between 400 and 43F.


I'm looking for the OSEK COM 1.0 standard. Does anyone still have a copy they could send me?

If you want to simulate a control unit yourself (in my case, the auxiliary heater), you have to add it to the gateway's configuration list, right?
From this point on, network management will inevitably become a necessity, right?

When you register the control unit in the parts list, you would likely also expect other control units to send messages using that same control unit. This applies not only to the NWM but also to other messages. The specific details depend on the respective control unit.
and exceeds my level of knowledge.

Luckily, I already know which IDs the auxiliary heater normally transmits.
The question now is whether this information is also forwarded to the Climatronic system, even if the gateway's parts list does not include the auxiliary heater.
Does anyone know the answer to that?

Okay, my understanding (from what I've gathered from various forums) is that when you 'code' a device in the gateway, it essentially only monitors whether the device is present. If it's not there, the gateway logs an error, but that's all the coding does.
Conversely, if a device is not encoded, it can still function because it registers with the network management system. However, this only applies to the various internal CAN buses, not to the powertrain CAN bus!

So, are these functions interesting for the management, right?

Unfortunately, I don't know about the Golf 5. For the Golf 4, the ring or the login was sufficient.

If you ever get a chance to take a log of a Golf 5 on a nice day, let me know and I'll tell you about it.

I'm definitely going to renovate tomorrow.
When it rains again, I'll go to my parents' garage.

Okay folks,
Today, I installed my control panel and, while I was at it, I also ran a CAN cable.
I did the whole thing in my parents' garage because it was 2°C outside with a light snowfall ( ).

PDC: CLICK
* Ignition on, engine off, in park.
* Reverse gear engaged.
* something maintained
* Parking.

Ignition: CLICK
Here, I've noted down everything that happens when you turn on the ignition.
Perhaps we can determine from this what is needed for the simulation of an engine control unit in terms of NWM (Non-Volatile Memory).
If anyone understands this, I would be happy to get a little help.

Sure, Maxx.

Okay, I've taken a quick look, and everything related to network management is still like a Golf 4. I'm getting another Golf 5 control unit (ECU) tomorrow or the day after. If it behaves exactly like my current one, then I know there's still a physical wake-up process involved.

What do you actually want to simulate a heater for? I might be able to help you with that, but I need to check something on my end first.

That would be great if you could help me with that .

Regarding PDC and wakeup: It is definitely a CAN wakeup.
The PDC control unit only has connections for power supply, CAN bus, and the four sensors.
I just verified it in the circuit diagram.

Why I want to simulate a parking heater. Long story...
Back then (November 2006), I couldn't order my Golf with a factory-installed auxiliary heating system.
A Webasto Thermotop P auxiliary heater was installed.
However, the control of the Climatronic system leaves something to be desired.
Before turning off the ignition, I need to set the temperature to HI and adjust the airflow to the windshield.
If you forget that,
It's not getting warm enough in the car, and the frost isn't melting.
The factory-installed auxiliary heater, which can now be ordered since April, is controlled via CAN bus and interfaces with the Climatronic control panel.
A heating system program is implemented there, which optimally controls the temperature, fan speed, and airflow.
In the Golf IV, the pre-heating program could still be started via 2 on a pin of the control unit.
The Golf V can only do that via CAN now.
Now I just want to go ahead and pretend to be the auxiliary heater.
The Webasto unit has a W-bus (I need to figure out what protocol is used on it, etc.).
My control system is ultimately intended to act as a translator between the W-bus and the CAN-bus.
For the Golf V control panel with SH programming, it's possible to activate functions like the ventilation system by manipulating specific bits.
I already tried using CAN-Hacker today, but it didn't work.

Okay, so that's the story...

Sure, Maxx.

You've set yourself quite a task .

I already have the wiring diagram for the PDC and have connected everything.

I hope that the settings aren't transferred via TP 2.0. I'm still struggling to replicate TP 1.6 on an AT90CAN128 (due to timing issues!), and TP 2.0 is even more timing-critical and complex!

Okay, so if you ever happen to have a log file from a parking heater, just post it.

Okay, I just checked your car's logbook, and it looks like you have a 3-door model.
Do you not have a navigation system or radio, or were they not turned on (or it might not have been a VW radio that sends data to the FIS)?

Well, it's enough for more, but not for memorizing, and it doesn't work for Golf 5 in my case. :-)

Did you capture the data at 100 kbps or 125 kbps?

I definitely have a 5-door car.
Today, I installed the parts myself, and interestingly, I saw on the comfort control unit that it's designed for a 2-door model.
That's probably why you ended up with a three-door car.
What does that mean for me? Should it not matter? Everything is actually working as it should.

The radio is the original RCD500.
In the MFA+ setting, the MFA prompt was active.
That's why no data would have been sent to the AI.

The TP 2.0 shouldn't personally matter to me.
I want to initially display nothing related to the auxiliary heater in the MFA (Multi-Function Display).

A vehicle log with a built-in heater would be fantastic.
I'm going to start a new thread in this forum with a call for something.
Few people will read this here.

Sure, Maxx.
