Master Stuck in Transport Mode

Transport mode on a newer Master? That's unusual. Does it happen after the battery was completely discharged? Some models enter this mode to conserve power during shipping or long periods of storage. Have you checked for any error messages on the dashboard or tried a basic system reset?

Battery wasn't completely discharged, and there are no error messages besides the obvious ones related to the malfunctioning systems. What kind of system reset are you talking about?

Okay, if it's not a discharged battery issue, and you're seeing multiple electrical problems alongside the transport mode indication, it's likely a deeper configuration issue. It almost sounds like the immobilizer is somehow involved. Sadly, I think you need to bring your Master to a workshop with Renault diagnostic tools. They can run a complete diagnostic check and recode the vehicle's configuration if necessary.

Thanks for the advice. I took it to the shop, and you were right - it was a configuration issue. They reset it, and everything is working fine now. Cost: 0€, as expected.
