Urvan turn signal malfunction

I had a similar issue with my Urvan, though it was a while back. Have you checked the wiring and connectors to the turn signal assembly itself? Sometimes a loose or corroded connection can cause all sorts of weird electrical problems.

Yeah, I gave the bulb connectors a quick look, but didn't dive too deep into the wiring harness. Where exactly should I be looking for these dodgy connections you mentioned?

Honestly, tracing those wires is a pain. From your description, it sounds like a cable or plug issue is the most likely culprit. My problem was similar, and in the end, I just took it to a workshop. Saved me a lot of headache, even though it cost 95€.

Ugh, that's what I was afraid of. Thanks for the insight; sounds like I'm heading to the shop. The error message disappeared after they replaced the defective connector. Money well spent!
