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.

Okay, regarding your question: I recorded it at 100kbps.
How does the log differ when I record at 125 kbit?

The TP 2.0 has nothing to do with the display.

TP 2.0 is to CAN what TCP/IP is to the internet (a very rough comparison).

'As you mentioned, some common applications of TP (Transport Protocol) include displaying information on the display, and the entire diagnostic process runs over KWP2000, which is tunneled through TP. Flash updates also use TP.'


Well, I didn't come to you about the 3-door issue because of your comfort control module; rather, it's because in the network management, only the driver's door, passenger door, comfort control, climate control, PDC gateway, and body control module were registered.

Well, theoretically, your power windows (if you have them), central locking system, and other features might not work in the rear doors, but as I said, I haven't actually disassembled a Golf 5 and played around with it yet.

'Golf4 is where my project is.'

Regarding the baud rate, it's supposedly possible for the Golf 5 to support 125 kbit, but it doesn't seem to be the case in practice.

Okay, I now understand what TP 2.0 is all about.
I'm going to test a 125 kbit connection tomorrow.
The el. The door handles and central locking system seem to be working fine on the rear doors.
This would mean that, even though the rear door control modules are not registered, it still works.
Could that mean I might also get lucky with the simulated auxiliary heating system?
In today's tests, I was unable to achieve anything using the CAN-Hacker.

Okay, here's the translation:

'Hmm, I received another PDC STG today, the same as the ones I got with my first ones.'

The weekend is just around the corner.

There must be some kind of physical trigger.

Best regards.

I've now connected the Golf 5 PDC to a Golf 4 dashboard, and you won't believe it, the network management of the Golf 4 and Golf 5 are still exactly the same . The PDC integrates beautifully into my dashboard. So, but now, my problem.
I'm connecting myself to the network, and while it correctly identifies the Golf 4 instrument cluster as my network node, it doesn't recognize the Golf 5 parking distance control (PDC) .

'When I simulate a Golf 4 Key Immobilizer (KI) 1:1, the Golf 5 parking distance control (PDC) doesn't respond. As a control test, I connected a Golf 4 comfort control unit to the simulator, and it successfully connects to the network.'

Could it be that the CAN-Hack USB device is experiencing some transmission issues? According to the specifications, the ComfortCAN should be a low-speed CAN bus (as stated in some VW SSP documents).

I'm going to try tomorrow (so, after I go to sleep tonight ) to see if I can get data from the PDC control unit using a Mega8 and an MCP2515.

@maxx
Did you send any messages to your Golf 5 that you received a response to, or did you just try playing around with the Climatronic?

Okay, so far I've only been trying to 'talk' to the Climatronic system.
If you need anything specific, just let me know, and I can test it.

Okay, here's the translation:

SG, Maxx.

Hi everyone.

I tinkered with my car a little bit again today.
The Golf V's comfort-related CAN bus operates exclusively with a bitrate of 100 kbit.
When you connect at a speed of 125 kbit, absolutely nothing happens.

Unfortunately, I haven't made any progress with my auxiliary heater issue yet.
Unfortunately, the Climatronic control panel doesn't do anything when I'm messing around with auxiliary heating telegrams.

Short question about network management.
Is it sufficient if I send a 'Ring' (is this equivalent to a 'booking' in the network?) cyclically?
If I do that, then the bus will at least not fall asleep .
Shouldn't the ID of the control unit be located in the first byte of the telegram?

When I press the 'instant heat' button on the Climatronic system, the following happens, as described in the attached trace.

Which NM telegrams relate to the Climatronic control unit? STG 08

PS: You are not allowed to attach TRC and TXT files to a post. That is quite uncomfortable. http://team-dezent.fimanist.com/CAN/Cli

I'm not sure yet, but it's possible that there might be issues with the high-speed Philips transceiver (which is also used in the can tool) and the low-speed CAN bus. I've now ordered some low-speed transceivers.

Please send me an email with the details of what you're sending (including the cycle type and what you're using as a trigger), so I can review your NM syntax.
