Volvo V40 Transport Mode Issue
Summary of the thread
A 2004 Volvo V40 is displaying 'transport mode' on the dashboard, leading to electrical malfunctions and a non-functional navigation system. This issue can occur when the car's system mistakenly identifies it as new, possibly due to an ECU error. A diagnostic check confirmed 'transport mode active' as the cause. The suggested solution is a visit to a workshop for a full ECU reset, which was ultimately resolved by the seller at no cost.

No, the battery hasn't been disconnected or replaced. A diagnostic check showed 'transport mode active' as the cause. Any other ideas?

If a diagnostic tool is flagging 'transport mode,' it's more than a simple battery issue. My Peugeot needed a full ECU reset, which only the dealer could do. Looks like the Volvo needs the same treatment. A workshop visit will be unavoidable, they will solve it.

I appreciate the advice. I suspected a workshop visit was inevitable. As the vehicle was new to me, I returned it to the seller who has resolved the issue. The repair cost was 0€.

That's weird. Something similar happened on my old 2012 Peugeot 308. It wasn't exactly 'transport mode,' but the electronics went haywire after a battery replacement. The ECU seemed confused. Did you recently disconnect or replace the battery? Have you tried a diagnostic check?
