0:00 Warning on the display
Here, the display reports a problem with the control unit. In this example, the free check shows that the motor's and control unit's system IDs do not match.
0:11 Prepare the connection
First check whether your control unit and browser are compatible. Switch on the eBike and connect the control unit with a USB data cable. A charging-only cable is not enough.
0:23 Connect in the browser
To connect, click Pair bike in browser. The selection window may show a control unit identifier instead of the bike's name. Select your control unit and confirm the connection.
0:38 Free system analysis
Start the free system analysis. The blue button indicates that resolution is available. Other functions remain locked for now.
0:47 Select and authorise the function
Select Resolve ID conflict. The initial check remains free. Resolution costs €19.99 including VAT. The operation starts after payment or redemption of a valid voucher.
1:02 Wait for the transfer
You can follow the transfer progress on the website. Wait until the website explicitly confirms successful completion.

On the Bosch smart system, 112002: the control unit's system ID does not match the motor's system ID. Bosch classifies this as an invalid eBike configuration. It can occur after components are replaced and may affect operation.
In the smart system example shown above, this display message was associated with an ID conflict between the motor and control unit. The free initial check detected the conflict, and the offered ID resolution was then completed successfully.
The error number alone does not guarantee an online repair. Only the free check can show whether a suitable ID correction is available for your eBike. The paid function is offered only if it is.
The relationship between the system IDs was checked in the Bosch partner catalogue. The manufacturer's public help page describes the configuration fault and refers customers to a specialist dealer: Bosch Help Center: error 112002 ↗. Content reviewed on 30 September 2026.
A different error number, or still seeing a warning?
A message such as “Control unit – contact a specialist dealer” can have different causes. Note the complete error number. A different code is not automatically treated as an ID conflict. If no correction is offered or the warning remains, send us the number and your control unit model using the contact form.
ID resolution corrects supported system associations. It does not remove a link to someone else's Flow account or replace an inspection of damaged components.
Resolve an ID conflict after replacing a component
The automatic correction aligns the system association of supported components. It is offered only if the free check detects an ID conflict that can be resolved.
Real-world check: verifying an ID conflict after correction
In a documented functional test on 24 September 2026, an ID conflict was resolved on the connected eBike. After the same bike was switched back on and its data read again, it no longer reported an ID conflict. What matters is the confirmed result on the bike; a progress display alone does not prove successful correction. The free initial check shows whether your conflict can be addressed online.
Distinguishing an ID conflict from a Flow account link
A link to a user account in the eBike Flow app is a different issue. This function does not remove someone else's account link or replace proof of ownership.
How successful correction is confirmed
After correction, completion is checked and shown on the website. The session is then ended. If online correction is not possible, the bike still needs to be inspected.
Questions about Bosch eBike ID conflicts
What does Bosch error code 112002 mean?
On the Bosch smart system, 112002 means that the control unit's system ID does not match the motor's system ID. Bosch describes this as an invalid eBike configuration. The free initial check shows whether this ID conflict can be corrected online for your bike. Bosch refers customers who see this message to a specialist dealer.
Can BlauWerk fix error 112002 online?
If the free initial check detects a supported ID conflict and offers the function in blue, you can select ID resolution for €19.99 including VAT. If the function is not offered or the error message remains afterwards, the bike needs further inspection.
When does a Bosch eBike ID conflict occur?
An ID conflict can occur when smart system components have been replaced or reassigned and their system IDs no longer match. The free initial check detects whether this is the case.
Can every ID conflict be resolved online?
No. BlauWerk offers correction only when the initial check detects a supported conflict that can be resolved online. Otherwise, the bike needs to be inspected directly.
Does this remove a link to someone else's account?
No. A link to a user account in the eBike Flow app is a different issue and is not removed by this function.
How much does resolution cost?
The initial check is free. A correction identified as available costs €19.99 including VAT.
Which payment methods does BlauWerk accept?
We accept PayPal, credit and debit cards, Apple Pay and Google Pay. The payment methods offered depend on your device, browser, country and the payment provider's approval.
