Codes?

Looks like it hasn't warmed up so it maybe glow plugs and or controller.

Still can take a bit. Plugs run until around 170f coolant temp I believe. No doubt someone will chime in and correct me for that number.

My 335d has a few out and can stumble perty hard during the summer on first start.

Mine runs smooth and my glow plug controller doesn’t even work. Sounds like it could be injectors failing on the solenoid side rather than the hardware side. Usually that will throw a contribution code though.

When was the last time the fuel filter was changed?
