Please help me identify this oil leak

Hi there.

Have a very slight leak coming from what might be the oil level sensor? however I'm not great with cars so could do with some clarification please.

Any ideas on exactly what it is and how to fix/cost etc?




Thanks

I have the same leak, which I am about to fix on my next oil change.

There is a seal behind the sensor that you need to replace next time you do an oil change (so oil doesn't come gushing out).

I've replaced this before, it's just a simple rubber washer. You just unplug the electrical connection to the sensor, unscrew the bolts, pull out the sensor (it's an 'L' shape so be gentle when getting it out of the hole. R&R the washer (if I recall correctly it only goes on one way, so observe how the old one comes off). The install is the reverse, make sure mating surfaces are clean, sometimes these rings burn onto the sump.

Looks like this one is available in the US:
