Oil level check/sensor issue E86 Z4 3.0si

Hi everyone, long time lurker here.
I recently purchased my z4, and it's been going flawlessly up until this point. I just went to check my oil after a half an hour drive, and it came back with the lowest bar. I'm aware that this sensor is only for the top 1 liter of oil, but I just had my oil changed last month. Unfortunately without much thinking, I just went and grabbed my oil and threw what I had left in(a whole 4 liters, what the hell is wrong with me :| ), and then ran the check oil again. It still comes back at the lowest bar and asking for another +1 quart of oil!!! I'm completely unsure of what to do at this point. I'm concerned that I could have a broken sensor, but I thought that the oil check would read ERROR. Obviously if that's not the case, then I'm worried I either have an oil leak/an issue along those lines, or that I just overfilled my engine with a ridiculous amount of oil.

I'm not sure how much it matters, but this z4 is tuned to 93 octane and I drive it just about as hard as possible every time I'm out. Any tips would be highly appreciated. Contemplating emptying my oil tomorrow morning and measuring it, to see exactly how much is in there currently.

Edit: What I meant to say, is that I am NOW aware that the oil check is only for the top 1 quart of oil. I unfortunately was unaware when I was pouring in 4 quarts :headbang:
 
The electronic dipstick can take up to a day to register a different level after adding oil, you need to remove 3 litres to correct the level.

Welcome to the forum.
Regardless of the behaviour of the sensor, I would certainly NOT be driving the car anywhere until you get that extra oil out!
 
Hi and welcome aboard. :thumbsup:

As has been said I wouldn't run the engine with that much oil in it! they only hold 6.5 litres, so yours must have about 9.5 litres in it. :o

If you drain it then put 6.5 litres in you should be good - but as Rob said the elctronic dipstick can take 50 miles or more to register a top-up based on my experience of them. :roll:
