AFN without immobilizer: Is it possible?

Hello,

For example, the Seat Alhambra or the Ford Galaxy? Does the Ford Galaxy also have the Volkswagen immobilizer system? Interestingly, the control unit of the Ford Galaxy has a Volkswagen part number!

Hello.
Wolfgang.

To the best of my knowledge, NO - meaning all AFNs with WFS.

Even the 1990s had WFS towards the end.

Sure, I will translate the text from German to English and correct it if necessary. Please provide the text you would like me to translate.

Hi,
There are AFNs (Asynchronous Flow Networks) used in industrial applications. They do not have WFS (Write-First Synchronization).
I am also not aware of any AFN passenger cars without a WFS (Wireless Fleet System).

Best regards, Rudi.

hi wolfgang,

I have no idea if it's a standard feature, but I have a STG (Steuergerät - control unit) from HA-Projekt without WFS (Wireless Frontend System).

Sure, here is the translation of the text from German to English:

Hello,

'However, the TDI industry ECUs have different specifications than the AFN and are not suitable for passenger cars. Recently, a Galaxy ECU was sold on eBay for a relatively high price, which led me to speculate that it might not have an immobilizer.'
The HA project seems to be removing the WFS (Wavefront Sensor), and we have something similar here, but it doesn't seem to be working; however, it's not clear what the problem is. We will probably need to buy a new one, so the question now is which one. For the 68-pin connector, there are 16 different control units available for the AFN engine.

Hello.
Wolfgang.

If the steering systems from Insturie and passenger cars are identical in terms of hardware.
Is it possible to combine the data stored in memory in such a way that it no longer has an immobilizer function? In other words, could the critical identification fields from passenger cars be copied into the data of industrial programs?
If someone has both programs available, could they please send them to me? Then I can see what I can do.

Hello Cord,
'You can't do anything with it. The information isn't stored in the data sets, but rather is saved through specific adaptation channels within the EEPROM, and only certain VAG testers can modify these channels (master devices; I have no idea if that's the official term).'
If you can get your hands on a TCU (Transmission Control Unit) without WFS (presumably a specific feature or component), you might be able to desolder the EEPROM (hoping it remains intact), guess what type it is based on the Bosch part number printed on it, read its contents, and then copy that data into the (also desoldered) EEPROM of the target device.

Best regards, Rudi.

I honestly have no idea about those TDI engine control units.
What I know is that there are comparison tables for Bosch models, at least for the older ones from around 1990. Once the EEPROM is extracted, it might be possible to access areas that are normally only accessible with login codes.
I highly doubt it can be that difficult.

Hi,
I once tried to sketch out (roughly) the internal structure of the transmission units.

Crash course on engine control units.
'Der schnelle braune Fuchs springt über den faulen Hund.'

The control units that are located in modern motor vehicles...
consist of the following functional groups:

- Data preprocessing.
'Der schnelle braune Fuchs springt über den faulen Hund.'
Sizes such as temperatures, pressures, frequencies, currents, etc., are processed in this way.
so that they can be processed by the controller.

- Communication
'Der schnelle braune Fuchs springt über den faulen Hund.'
The internal signals are processed in a way that allows the controller to...
can communicate with its environment (using CAN, RS232, RS422, ISO9141, etc.).

- Power supply
'Der schnelle braune Fuchs springt über den faulen Hund.'
The on-board voltage will be processed to provide a stable 5V supply.
comes out.

- Output driver
Certainly, please provide the German text you would like me to translate into English. I will only provide the translation.
Control of various actuators. For example, in VP-TDi systems, this includes quantity setting devices.
Exhaust gas recirculation, injection timing, ...

- Processor core
'Der schnelle braune Fuchs springt über den faulen Hund.'
The processing core controls and regulates the entire system. It can be divided into the following components:
Split subgroups:

-- Controller
CPU, which – unlike, for example, the CPU in a PC – usually already includes a wide variety of...
It includes functions for use in an embedded control unit (UART, timer, etc.).
ADC, DAC, etc.).
Older TDI engine control units (ECUs) often used chips like the 80C517 from Siemens.
(MSA11, MSA12), of which two were required; one for...
the control of boost pressure and the control of fuel injection volume; in these.
Therefore, STGs have two complete processor cores.
More recent engine control units (ECUs) often use components like the C166 or C167 from Infineon (formerly Siemens).
Unfortunately, I can't tell you what's currently included in those specific products, as I haven't been updated with that information yet.
I haven't gotten my hands on any to take apart .

-- Program memory
In the very old programmable logic controllers (PLCs), there were EPROMs inside (with glass windows; they could be erased).
and reprogrammed). Later, OTPs (One-Time Programmable) emerged, which are also...
EPROMs, but without the glass window (making erasing impossible). These were often already pre-programmed.
SMD components used. Both types had to be programmed before being installed into the control unit.
'Flash building blocks have been used for some time now, and they are integrated into the control unit.'
can be programmed.
The actual program of the ECU and the characteristic maps are stored in the program memory.

-- Memory
RAM: This is where the controller can store data during program execution.
This data is volatile! That means: if the power goes out, the data is lost.

-- Parameter storage
EEPROM: This type of memory is non-volatile and can be written to and erased during runtime.
This memory stores parameters such as encoding (transmission type, etc.), immobilizer data, and...
GRA, various adjustments... This building block also includes the error memory!

@ Cord

It's not that difficult to identify the EEPROM type, as at least the manufacturer's logo is usually printed on it. Then you have to review all relevant datasheets and hopefully find the correct one by examining the pin configuration. You'll likely have to guess the memory size.
The source for the comparison table would interest me .

Best regards, Rudi.

Good evening.
due to the comparison tables.
I haven't seen that one yet, but the software from Batronix EEpromer also allows you to select Bosch types for the B57 and B58 series.
For example, the Bosch B57604 (such as the one installed in the Monojet from AAK) is comparable to the 27C128.

You can also find out the Bosch type numbers here.

"I salvaged a control unit from scrap and reloaded the software – it's ready! If you want to remove the WFS (presumably a security feature), for whatever reason, you have to send it in, and someone will desolder certain components, after which it will work without it. Now the question is, who does that? I have no idea; my friend has one because we're converting Bullis with TDI engines. If there's interest, I could ask him. But my opinion is that you can easily adapt an old WFS to a new control unit using VAG-COM full version – it's not a problem, I've done it 5-6 times already; it's child's play."

What did you take?

Do you mean someone waited four years for your comment?

Greetings,
dieter

Hi Dieter, I'm sorry, I accidentally came across the question and was so busy that I completely missed the deadline. As I said, sorry. Everyone has a dark moment sometimes .

Why not? It's nice to be able to find your old posts again .
After 4 years, you also see the WFS from a different perspective.

Hello.
Wolfgang.
