2005 BMW 325i 2005 e90

BMW 325i (year of manufacture 2005) The vehicle was regularly maintained. Recently the following work has been carried out:

* Crankshaft sensor renewed * VANOS units and VANOS sensors renewed * valve cover seal renewed * Both seals on the oil filter housing/oil cooler renewed When I get the car full. Get it out of the top. However, if I have 1/2 liter less than full refuel it does not happen. Thus it has no great effect on the car

The engine runs smoothly and perfectly.
