Hey guys. My car is using alot of oil and I have to fill it with 500ml every 300-600 km's then the next thing happened. The car lost power and went into limp mode and I could hear it was only running on 3 cylinders. I checked the spark plug, injector and the coil pack and they all tested ok. I have found that it is the number 3 cylinder that is not working correctly. Is there something specific that I need to look out for or should I check the valves on the head? I woukd really appreciate any in put. Johann...
