Hi! I recently changed the oil filter housing on my 2.0 fsi engine and by doing so the engine does no longer leak any oil or coolant. The car has been standing still for four months on the other hand which might have had a negative impact. Do take into consideration that i have cleaned the throttle body in an attempt to see if that would fix the problem below. So during the repair i broke the housing for the oilstick which i changed and also one of the ventilation hoses for the crankcase. When i started the car and started driving it i have realized that the car has a very rough idle (about 800 revs but sounds like it is working very hard and it consumes 2.5 l/h instead of the usual 0,6-0,8 l/h). It also has a ragged engine character at low revs. If i keep the same level of pressure on the accelerator the car basically jumps a bit (sometimes fuel and some times not). The engine also spits out tremendous amounts of white smoke from the exhaust pipes. This has been the case before but not as much as right now. There is constant level of coolant in the reservoar and no water in the oil. Im thinking condensation..? The car hasn't been driven for very long distances in the past and has been staying still as i have written for a long time in winterweather (snow and rain all day). I just fueled it up from 10 liters (old petrol) to 30 and dumped a injector cleaner in the tank. Could all of this be because of bad fuel, combined with clogged injectors? In that case this might work? Or is this optimistic. No fault codes, no check engine light and so on. Kind regards! Emil
