Germany is in second place in this list, with a combined iron and steel import value of $31 billion USD in 2014. The reason behind such immense iron and steel imports by Germany is that of its top position for iron and steel products across the world as a supplier, notably including automobiles and heavy machinery among them.
Engine Oil Pressure Warning. The engine oil pressure warning light comes on when the oil pressure sensor detects low oil pressure. This could indicate low engine oil level, a loss of engine oil pressure or a faulty engine oil pressure sensor. The engine oil level and pressure should be checked immediately. Low oil level or low oil pressure will cause serious damage to the internally lubricated parts of the engine. Battery/Charging Alert.
Incorrect Flame Colors. If the pilot light in your gas heater shows a lot of yellow, orange, red, purple or green color, this indicates inefficient combustion because other condensates are burning along with the methane. These condensates might include tar, dust, rust or oil, all of which are potentially hazardous chemicals.
