Hello, I had the auxiliary heater upgraded to a full-fledged heater at a VW dealership 4 years ago.
Now it's broken. I had it replaced, and they need to re-pair it.
What's new is that the car's diagnostic scan now shows a "7D" code, which indicates an issue with the auxiliary heating system.
The people at Bosch who installed the heating system probably don't know what they're doing!
I just checked and saw that the heater is listed under "equipment for vehicles under 18" and is being identified as a supplemental heater.
Now, all they have to do is install the new software!
Or.
Here's my scan.
Can you help me with that?

Okay, let's write this down again.
1. The vehicle was originally equipped with a Webasto auxiliary heater from the factory.
2. You had the auxiliary heater upgraded to a full-fledged heater via a software update purchased from VW.
3. Bosch has now installed a replacement heater core.
Is that correct?
If so, unfortunately, it will be expensive again.
The SW update of a Webasto auxiliary heater to a stand heater is performed using a license dongle.
This dongle can be used exactly once. After that, it is consumed and only suitable for recycling.
The dongle costs almost âŹ400 and is part of an upgrade kit.
The dongle is not sold separately.
So, I would go to Bosch and demand that they install a stand-alone heater for you.
Of course, you should have the VW invoice with you to prove that the defective old device actually received an upgrade.

Hello, yes, so far, everything is correct.
Pre-heater.
Upgraded at VW 4 years ago.
3. Replacement of the Bosch heating system as a supplementary heater.
4. The dongle is present, but they cannot install it!
"So, the problem, according to Bosch, is that they can only upgrade the system if they have access to the auxiliary heater."
What I can't understand is that they should have access, see point 18... The function /7 D Zuheitzer is not correct!
If I'm not mistaken, there shouldn't have been a 7D heater code on my car's diagnostic scan before.
Bosch stated that the gateway was not communicating with the auxiliary heater.
They want to explain to the Touran that it is a pre-heater. However, the Touran already knows this, as it can be seen on setting 18, under the "Component: Pre-heater" section.
P.S. The auxiliary heater is also working as it should. It turns on at temperatures above +5°C, and can be deactivated using the "Econ" mode.
They just didn't explain how they could get the software to run on the older device.

Is the auxiliary heater connected via a Webasto USB adapter?
If you haven't installed a wireless remote control, the message 'W-Bus communication error' is normal.
Can be ignored.
The update can be installed by anyone, so you don't need to take it to a workshop.
I think I'm going to switch to a different Bosch workshop, especially since I don't understand why they didn't just install a standing heater in the first place!
'You could have saved the 400 euros for the upgrade!'

Hi, I'm not sure what problem they're having with the software update.
And Webasto provided the software free of charge.
If you look at my car's diagnostic scan, what would you say about it?
"That 7D control unit is wrong, isn't it?"
Can they not install the software update via the in-car entertainment system?
And VCDS doesn't work for flashing the software, as I was informed by VCDS.

I would like to try disabling the auxiliary heater in the gateway (address 19) and then address the error messages in the control unit address 18 (http://www.obd-info.de).).
Possibly, the air conditioning system and the vehicle's onboard network control unit are also incorrectly coded (set to auxiliary heater mode). So, clear all the error codes and see which ones reappear.
Best regards, Rainer.

Hello, I have a question about this upgrade.
How should this be implemented? Should the software automatically detect the heating system, or does it need to be configured manually?
Example 18: Auxiliary heater installed, and we're ready to go. Or, how should I envision this upgrade?
Since I'm not yet clear on why Bosch is serving the "Zuheitzer 7" with a specific encoding in the gateway.
Since the heating system is already operating below 18 degrees Celsius, the auxiliary heater component would be activated.
Thank you.
P.S. If I want to perform a long encoding process and then click "close," I get error 31.
I don't have the login code. Where can I get it? My VCDS doesn't show it to me with a pop-up.
Or am I doing something wrong? Otherwise, I would have tried them out myself over the weekend.

The Webasto upgrade kit includes all the necessary parts, both hardware and software.
First, you need to check the software version in the control unit of the auxiliary heater using VCDS. If it is below version 13.12, you must first update the auxiliary heater software to version 13.12 or higher. However, this cannot be done with VCDS. Then, clear all errors. If there are serious errors stored or the heating unit is locked, it must first be repaired. Fortunately, this probably doesn't apply to you.
Imagine this: The adapter cable, where this dongle is inserted, must be directly connected to the heating system. And it should be connected not through the car's OBD socket, but via an (included) adapter to the connector of the control unit, whether it's a clock or a remote control.
Okay, so you connect one side of the watch adapter to the watch and the other side to the USB port on the computer. Then, insert the Webasto CD and start the program "upgrade.exe". And that's it.
After that, you can use VCDS to desensitize, for example, the interior monitoring system by 50%, if available. Then, you can perform another system scan.
These upgrade kits actually come with a detailed instruction manual.

Thank you for the detailed report.
The problem, according to Webasto, is that the device cannot connect to the heater via the 1533 interface using the dongle, and an error message is always displayed.
It's likely that the auxiliary heater needs to be coded in the vehicle's control unit (possibly module 17) by a VW technician because the Webasto specialists are unable to resolve the issue.
The Bosch technician just called me and said that he tried everything as you described, and he's still getting the same error.
He wants to go to the VW dealership today, as mentioned, with the Touran to have the coding done.
And Webasto recommended installing the Gateway 7D coding.
Thank you.

It's okay to first reset everything to the original state, i.e., the auxiliary heating mode, because the upgrade software also expects this state.
Then there's another point: Is the heating system software version 13.12 or higher installed?
Is the dongle really okay?

Okay, they just called me and said they unfortunately can't install the software.
There is no connection established with the heating system. VW's online support also doesn't have a solution, and they say that the CAN bus line is likely not communicating.
I could really use a good tip right now.
Thank you.

Hello, I need some help with tax code 19. Apparently, Bosch hasn't been able to decode the "7d" sequence.
I'm using the full version of the software and want to modify the long code, but I don't have the LOCIN code. Can anyone send it to me?
Or...
Thank you.

Hello!
You don't need a login code for that.
You go into the control unit 19 and then click on "Parts List". There, you can add or remove checkmarks as you like. At least, that's how it works for me.

Okay, thanks, I'll try it out later.
Thank you.
I'm not yet sure why I can't access the heating system through the pre-selection interface (1533 cable) to install the software and turn it into a stand-alone heater.
Since the heating system was upgraded from a basic heater to a standing heater, the wiring is still the same as it was before.
The only thing that was different for me was that the Y-cable had an LED that indicated the power-on point, which I had to disconnect (cut). Otherwise, the pre-selection timer didn't work.
Could it be that I need to bypass this cable with a light bulb to restore the connection to its previous state?
But I also read something about swapping pin 1 and pin 2!

Hello, the software is installed, but the remote control and pre-selection functions cannot start the heating, and I still need to test whether the auxiliary heating function works.
I still need some tips.
Thank you. Wednesday, October 19, 2011, 09:31:33:26452.
