Volvo S60 Transport Mode Issue

Oh dear, that sounds incredibly frustrating! Transport mode is usually only active when the car is being shipped from the factory, so for it to appear now is quite unusual. Have you tried the basics, like checking the key fob battery or seeing if the immobilizer is playing up? Maybe even a simple system reset?

Yeah, key fob battery is fresh. How would I check the immobilizer, and what's the procedure for a system reset on this model?

Well, checking the immobilizer usually requires a diagnostic check with proper automotive diagnostic tools, which is probably best left to a professional. Regarding the system reset, I'm not entirely certain on the specific sequence for your S60 model, and I wouldn't want to provide any misinformation that could worsen the issue. I am sorry I can't be of more help, but I would strongly recommend taking it to a Volvo workshop – they'll be able to perform a software refresh and properly diagnose what's going on.

Appreciate the input. Turns out it was a software glitch related to transport mode not being deactivated properly at the dealership. Dealer sorted it with a software refresh, no cost. All good now.
