the car is freelander 2 2.2 td4 automatic 150bhp year 2008
problem started a week ago, when the cold weather arrived.
Difficult engine start in the morning,a little white smoke.
Missfire and difficult runing from 1000 to 2000 rpm,after 2000 runing ok.
Sometimes runs ok,without any problem.
Any ideas?

If it started with the cold weather then the first port of call for me would be the glo plugs. They are used for a while after the engine has started to run to assist with ignition as well as warming the cylinder before starting.

thanks for the reply!
i know they are used for a while after the engine has started to run but we are talking about a max of 3-5 minutes... my car continues tu run bad landg after that .

The glow plugs are modulated on and off for a long time after starting, depending on engine temperature. The longer the engine takes to warm up, the longer the plugs are run for. Hyundai Ioniq 5 Ultimate. The family car.
