Mk2 1.6hdi rough idling when cold

[Mehmet Salahi Mehmet]

Me again. Terrible forum gremlin I am. I noticed the common problem with injector 3 so I tightened it up which stopped fumesin the cabin. But what causes the rough idling when cold and the smoke? I understand that is unburnt fuel. Changing the Thermostat and blanking off the EGR soon. So quite like to do everything in one hit

Thanks everyone!

I had the very same rough running from cold and smoke on my 1.6 hdi changed the glow plugs and all was well.

Thanks V6BOY. Ill get some ordered. It had a full service before I bought it. But you can never trust traders

Sometimes it's something as simple as keeping your foot away from the accelerator pedal when starting the car Mehmet.

LOL, if only it was that. ive been looking into the glow plugs. Apparently they are a PITA. Snapping and causing all sorts of problem's. That's a worry!
