Loose or corroded ground wires can interrupt communication between the ECU and the immobilizer. One well‑documented case involved the ECU’s mass wire behind the steering column fuse box; after securing that connection, the Start Error vanished. Always inspect all ground connections, especially the main engine ground strap.

The "Error 13" you mentioned seems to be a generic or specific fault code. In the context of Mercedes or general automotive troubleshooting, error codes are usually more specific, often consisting of a letter followed by a series of numbers (e.g., P0130). Without a specific code format (like P0xxx or P1xxx for OBD-II codes), it's challenging to pinpoint the exact issue.
The chip inside the key (transponder) communicates with an antenna ring around the ignition lock. If the transponder is damaged or the antenna ring fails, the immobilizer never receives the correct code and blocks starting. Replacing the ring or the key is straightforward, but the new parts must be coded to the vehicle. Loose or corroded ground wires can interrupt communication
Once you have solved the error via a downloaded fix or professional repair, prevent it from returning:
If you have a spare key, try it. If the spare key works, your primary key may have a faulty transponder or a dead battery (for remote functions). If neither key works, the issue is likely with the vehicle's immobilizer system.
