Madalina Moman, author and publisher

Author and publisher

Madalina Moman publishes and maintains Error Code List from Sindelfingen, Germany. She also oversees the editorial content of Fehlercodeliste.de.

Editorial approach

The guides use manufacturer information to explain a displayed code, its documented scope and the next supported checks. They distinguish reference information from diagnosis and make model limitations visible.

A published explanation is not a claim that the writer inspected your device or vehicle. Follow your product instructions and seek qualified support for work outside the checks described there.

References and corrections

Sources and check dates are listed in each guide. Read the editorial standards or send a correction.
