Mercedes A Klasse transport mode issue

My 2021 Mercedes A Klasse with a gasoline engine is showing transport mode active at 69413 km. This causes electrical malfunctions, especially with the navigation system, and I think it's affecting the immobilizer since the engine sometimes won't start. I ran a diagnostic, but the setting is still there. The key fob seems fine. Any ideas?

Summary of the thread

A 2021 Mercedes A Klasse is experiencing electrical malfunctions and engine start issues due to an active transport mode setting. The problem is suspected to be linked to a corrupted vehicle setting during transport, affecting systems like the navigation and immobilizer. A suggested solution is a hard reset by disconnecting the battery, but a more effective resolution involves a software fix at a workshop, which successfully resolves the issue.

Sounds familiar! I had something similar happen with my A Klasse. Have you tried a hard reset? Disconnecting the battery for a bit might clear the error. It's worth a shot before you get too deep into diagnostic check procedures. Did you notice any other weird electrical stuff happening?

When you experienced this issue, did it also affect the engine start functionality or any other critical systems? I am trying to ascertain if the symptoms align closely with what you encountered before proceeding with further steps.

Yeah, the engine start was occasionally a pain, like the immobilizer was playing up. Honestly, it was a bit random. Battery disconnect might work, but in my case, it only helped temporarily. Ended up taking it to the workshop, and they sorted it with a software fix. They said something about a corrupted vehicle setting during transport. Hope it helps!

I appreciate your guidance. Based on your experience, I took the vehicle to the workshop. As you suggested, a software fix rectified the issue. The transport mode was indeed the culprit, and the electrical malfunctions have been resolved. Thank you for sharing your insights.
