Urvan Diesel Injection Problem

Sounds like dodgy injectors, especially with the smoke and stalling. Have you checked the cable and plug connections? A loose connection can cause problems. What's the mileage?

I wiggled the cables and plugs, but nothing obvious. Mileage is 145785 km. Any specific connections I should focus on?

With that mileage and no obvious cable issues, it's likely a deeper injection system problem. If you're not confident with diesel injection, take it to a workshop. They'll have the tools to diagnose it.

You were right! It was a defective plug connection. They cleaned it, and it runs great again! Cost 95€, a steal compared to a new engine. Thanks for the advice!
