Troubles with the oil level sensor and long start?
Problems with a EU 2000 facelift 320 w208 model oil level sensor. Ever since my oil level sensor went bad from I assume age almost 300000 km on the car. Having replaced it with a GEBE branded oil level sensor it read it wrong sometimes said ok, but most of the time said to add 2L even when it was measured on the dipstick to be at max. Noticed also that the rubber was very stiff as if it had sat on the shelf forever. After having replaced the sensor again through warranty I received a Febi Bilstein one that measures the oil level correctly always, but during a longer drive it always pops the reduce oil level in red. These always dissapeared when i've stopped the car, but I would like to fix the issue permanently. I'm wondering if the problem is still within the sensor and do I have to get the insanely overpriced OEM sensor? I noticed that after having stopped the car and waiting atleast 5 min to check through the instrument panel the oil level still reads that it should be reduced. Im wondering if the problem is even still electrical or a sensor problem. Feels as if the problem only shows when the engine warms to normal temp.
The oil has been renewed and im also having a tiny problem with starting the engine after it has been driven and cooled a bit for lets say 10 minutes it starts for about 3 seconds longer than usual. The pressure drops at warm temperatures I assume and the engine builds it up again when trying to start? Messing with the relay showed me that the cars pump works normally and builds the pressure, but for some reason when starting it does not pre pressurize the fuel rail like it should after it has sat for a day.
I'd appreciate any answers relating to the problems!
