Control unit list
Which units answered and how many faults each has. A unit with no faults, a unit that did not answer and an unsupported request look different — an empty list is never passed off as "all fine".
AvailableInstalled with the same installer as CarPlay → HUD
BMW fault codes on the built-in screen
Read the fault memory of your car's control units straight from the NBT Evo menu — no laptop, no adapter in the OBD port, no phone app. The code, status and a plain-language description of every fault.
- No laptop or adapter
- Descriptions in several languages
- Works offline
- Read-only
How it works
- 1
Open diagnostics
In the car menu, like any built-in screen. Nothing to plug in.
- 2
Start reading
The head unit queries the control units one by one. You see how much is left and can cancel at any time.
- 3
See the result
A list of control units with fault counts, and a card for each fault with its code, status and description.
What it does
Fault card
The raw code, the status — whether the fault is present now or only stored in memory — and a description. If there is no description, the code is shown as is, with no guessing.
Built-in reference
Control unit names and fault descriptions in several languages are stored in the head unit itself. No internet or phone needed.
Only when you ask
Reading starts by hand and never runs in the background. While it runs, the car menus work as usual.
Read-only
Diagnostics never clears, codes or programs anything. Clearing faults and repairs are for the workshop.
What you need
- A BMW with the NBT Evo head unit
- A supported head unit software version — the list comes with the release
