BMW CC-ID Fault Code Calculator

This tool allows you to decode BMW CC-ID (Check Control ID) error messages into meaningful diagnostics information. CC-IDs are internal BMW codes that control warning messages displayed on the instrument cluster and iDrive screen. Each CC-ID maps to a specific byte and bit position in the CC_AKTIVIERUNG CAFD coding data.

How It Works

Enter a CC-ID code (0–4095) to instantly calculate the exact group, byte number, bit position, and hexadecimal coding value needed to modify that check control message in your BMW coding software. You can enter multiple CC-IDs separated by commas or spaces, and the calculator will merge the coding values per group — ready to paste directly into your NCD coding tool.

What Are BMW CC-IDs?

BMW Check Control IDs are numerical identifiers assigned to each warning message in the vehicle. Examples include low fuel warnings, door open alerts, tire pressure notifications, and service reminders. The CC_AKTIVIERUNG parameter in the CAFD controls which messages are active. Understanding CC-IDs is essential for advanced BMW coding operations.

Built-in CC-ID Database

Our calculator includes a database of 1,235+ known CC-IDs with ECU names and descriptions. Search by keyword or CC-ID number to find the exact warning you're looking for. For related diagnostic codes, see our BMW DTC code reference.

Frequently Asked Questions

What is a BMW CC-ID?

A CC-ID (Check Control ID) is a numerical code that BMW uses internally to identify specific warning messages displayed on the dashboard. Each CC-ID corresponds to a particular vehicle condition or alert.

How do I use the CC-ID values for coding?

After calculating the byte/bit position and hex value, apply it to the CC_AKTIVIERUNG parameter in your vehicle's CAFD file using a coding tool. Read our NCD coding guide for step-by-step instructions.

What BMW models support CC-ID coding?

CC-ID coding applies to all BMW models with NBT, NBT EVO, MGU, and EntryNav2 head units. This includes most F-series (2010+) and all G-series vehicles.

Can I calculate multiple CC-IDs at once?

Yes — enter multiple CC-IDs separated by commas, spaces, or newlines. The calculator merges all values per group, producing ready-to-use coding data.
