I noticed that my 300 TDI defender always struggles to get up the driveway when starting it cold in the mornings. Even in warm weather. The driveway is not excessively steep and I never saw any other car struggle. Even with the foot to the floor, I usually struggle to get up even when in low range. I somehow just accepted this as "well that's how it is...". Otherwise I never notice a distinct lack of power when driving it on a flat road. When the engine is warm after driving for a while, the defender is still struggling a little, but manages better.
Now that it's getting a bit colder and closer to freezing, I also started to notice two other problems:
1. On start-up, it sometimes takes a few seconds until it gets going under a lot more initial black smoke than usual. The engine turns, but doesn't seem to fire properly.
2. When I accelerate after starting the engine, it doesn't rev up initially at the very first try in the morning. There is a solid ~3 second delay until the engines gets revving. When it eventually works, the engine start "coughing" a lot of black smoke when the accelerator is let go. I uploaded a video to show the second part: It was worse when I tried it just before without recording it.
The injector pump is brand new. Fuel filter is also new. I also checked the earth to the bulkhead- seems fine. I also checked the voltage on each glow plug and couldn't find a fault with it. Could all my problems be related, and if so, what could be the culprit?
