Reset service indicator
-
Code new modules or perform adaptations

Compatibility
✅ BMW E-series from 1998 to approx. 2013 – E36, E38, E39, E46, E53, E60, E61, E63, E64, E65, E66, E70, E83, E87, E90, E91, E92, E93 etc.
✅ Requires Windows PC (preferably 64-bit)
✅ The adapter should have the correct switch (K-line/DCAN) or automatic switching

💡 For models after 2013 (F-series and newer), different hardware is required (e.g., ENET cable or ICOM).
Installation – what you need
-
K+DCAN cable with the correct chip and driver
-
BMW Standard Tools package (incl. INPA & NCS Expert)
-
FTDI driver (often included or can be downloaded)
-
Windows computer (preferably not with too many security restrictions)

OBD2 socket in the car (usually under the steering column)
⚠️ Many users choose to install the software on a dedicated older laptop, to avoid conflicts with modern security systems or updates.
Frequently Asked Questions
Is the software free?
INPA and related tools are often based on BMW's internal tools, but are available through enthusiast networks. Installation guides and support forums are common resources.
Does it work with Windows 11?
Partially – but it works most stably with Windows 7 or Windows 10 (64-bit).
Can I program new keys or modules?
In some cases, yes – but it requires knowledge. INPA is primarily for diagnostics, while, for example, NCS Expert and WinKFP are used for coding/programming.
What is the difference between K-line and DCAN?
-
K-line = older vehicles (approx. 1998–2006)
-
DCAN = newer E-series (2007–2013)
The K+DCAN adapter handles both – some have a manual switch, others switch automatically.
