Vw polo 2000 1.4 tdi rear lights not working fuses and bulbs fine. After checking bulbs one light worked but other does not. More than likely its bulbs . Vw polo 1 litre has idling problems it keeps reving to around 800 rpm then droping to around 400/500 all the time engine being cold or warm makes no difference.
Symptoms: -it starts with difficulty when engine is cold. -sometimes when cold starting in the morning it throws a more than normal amount of black smoke out the exhaust. -idle is faulty, it has a small but visible oscilation. -when driving it seems that the engine has only 80-90% from the normal strength.
