Can I also download updates with the program?

Yes, according to the feature list provided in the first post, this version (8.1.6.0) supports firmware updates. You should be able to update the eBike components (such as the drive unit, battery, and display) using this software.

When I want to do an update, the error message "Update server not reachable" appears. Please check the server url and the proxy settings". What do I have to do to make it work?

This is expected behavior when using a patched version.

The error Update server not reachable occurs because the software is trying to connect to the official Bosch backend to download firmware files. This process requires a valid authorized dealer account (login/password) and usually the specific hardware dongle to authenticate with the server.

The patch bypasses the local login requirement to let you use the diagnostic features, but it cannot bypass the server-side authentication required to download updates. You are likely limited to offline diagnostics and whatever firmware database is already included in the installation.

Hello! Where can i find password?

Hello and thank you that the software is still available for download in this forum.
Before I start the download, however, I have a question.
Am I correct in thinking that it is only the dealer version and the unlock files for manufacturers/OEM are missing?
Since I would have to install "Conway.bpc" on my new engine, I would be very happy if you knew a source for OEM.
Thank you and have a sunny weekend

totaconf · 13.04.2026

will test for sure!

Regarding OEM brand configuration files (.bpc)
You are correct — this is the dealer diagnostic tool itself. OEM-specific brand profile files like Conway.bpc are not included in this package. These .bpc files are manufacturer-specific configurations that define things like speed limits, branding, display settings, and motor behavior for each bike brand.

Unfortunately, .bpc files are distributed by Bosch exclusively to authorized OEM partners and are not part of the DiagnosticTool installer. They are loaded separately and tied to the specific manufacturer's dealer agreement.

What you can do with this tool without .bpc files:

Read and clear diagnostic trouble codes
View live data and system parameters
Check component serial numbers and firmware versions
Generate PDF service reports
Configure basic settings (wheel circumference, units, lighting)

What you cannot do without the correct .bpc and dealer backend access:

Flash OEM-specific brand profiles onto a new drive unit
Download firmware updates from the Bosch server
Perform remote diagnostic sessions

If you need to install a Conway profile on a new motor, that typically has to be done through an authorized Conway/Bosch dealer who has the .bpc file and valid server credentials. If anyone in the community has more info on sourcing OEM profiles, feel free to share.

Hello,
thank you for sharing.
Is it possible to increase the maximum speed from 25 to 32 km/h with this software?

No, this is not possible with the Bosch DiagnosticTool.

The speed limit is hardcoded in the drive unit firmware and enforced by Bosch at a system level. The DiagnosticTool allows you to read/clear faults, view live data, adjust basic configuration (wheel circumference, lighting, display units), and generate service reports — but it does not provide access to modify the speed limit parameter.

Even with the correct OEM .bpc profile, the speed limit is not an editable field in this software. Bosch specifically locks this down for legal/type-approval reasons.

If you are looking for speed derestriction, that is a completely different topic involving either:

Hardware dongles (e.g., SpeedBox, BadassBox, etc.) that manipulate the speed sensor signal
Firmware-level modifications to the drive unit — which require a full dump of the controller firmware and knowledge of the map structure

Both approaches carry risks (warranty void, legal issues depending on your country, potential CAN errors). The DiagnosticTool is strictly a diagnostic and configuration utility, not a tuning tool.

ok, I saw solutions appear without a dongle but with license keys. I was wondering how this was possible. thank you

Hello

Someone find how force OEM mode ?
I can have the GUI in OEM but I have communication error with drive unit and battery.
Maybe someone can help me

Hello

That's an interesting question. To help you properly, I need a few more details:

Which drive unit do you have? (e.g., Performance Line CX, Cargo Line, Active Line Plus — and the exact part number like BDU3xx if you can find it)
Which battery? (PowerTube, PowerPack, part number)
How exactly are you connecting to the bike? (USB cable directly to the diagnostic port, or through some adapter?)
What did you do to get the GUI into OEM mode? (Did you load a specific .bpc file, modify a config, or use a specific menu option?)
What is the exact error message you see? ("Communication error" — is there an error code or more detail in the log?)

Here is what is likely happening:

The DiagnosticTool has two main modes — Dealer/Service mode and OEM mode. OEM mode expects a valid .bpc brand profile to be loaded and typically requires the Bosch USB security dongle to authenticate the communication session with the drive unit and battery over CAN.

If you forced the OEM GUI (e.g., by placing a .bpc file or modifying a configuration), the interface may load, but the actual CAN communication layer still needs:

A proper physical connection — the Bosch diagnostic cable connected to the bike's service port
The USB dongle for authentication — in OEM mode the tool often requires dongle-based handshake before it will talk to components
A matching .bpc profile for your specific bike brand/model — a mismatched profile can cause the tool to send incorrect initialization commands, resulting in communication errors

If you can share the exact steps you took and any log files from the tool (usually found in the installation directory under a logs folder), that would help narrow down whether this is an authentication issue, a cable/connection issue, or a profile mismatch.

Thanks for the info. Here's what we know:

Motor: Performance Line CX Gen 2 (probably BDU350 or BDU365)
Battery: Horizontal PowerTube 500 (probably BBP2xx)
Bike: Mondraker

I'm still missing a few details to help you:

How are you connecting to the bike? Bosch diagnostic USB cable connected to the motor's service port? Which cable exactly?
Is the Bosch USB dongle present? (the hardware security token) — without it, OEM mode cannot authenticate the CAN session with the motor and battery, which causes exactly the communication error you describe.
How did you activate OEM mode? Did you load a Mondraker .bpc file, modify a config file, or something else?
What is the exact error message? If you can take a screenshot of the error et/ou check the logs (in the installation folder, often under logs/ or data/), that would help a lot.

What is most likely happening:

In OEM mode, the DiagnosticTool attempts authentication via the USB dongle before opening CAN communication with the drive unit and battery. Without a valid dongle (or with a .bpc that does not match Mondraker), the handshake fails → communication error, even if the OEM graphical interface loads correctly.

In Dealer/Service mode (without .bpc), you should be able to read fault codes, view live data, and component information without any problems. Does Dealer mode work normally for you?
