Where is my oil going?

Hi all -

My 2013 335i just started to really eat oil. We did a road trip to washington DC from Florida about a month ago. On the trip, I threw a P301 and went to limp mode. I Ubered to BMW and got a new ignition coil and replaced it and the engine was happy again. No codes.

Fast forward about 2 weeks and I get a P301 and P305 and a low oil (the yellow "Add 1 quart" alert). I was suspect of the P30x codes because I just replaced the ignition coil on cylinder 1. So, I added a quart of oil. Codes went away and all was good. About 2 days later, it's asking me for another quart. I add one. Next day... asks again.. I add one more and test again (after 3 minutes). Still low, so I add a 2nd and test Still low. Now I'm wondering about the sensor, so I drive home.

Today, I checked again. Added one. Checked. Added a 2nd. After the 2nd... It went red. Said I was LOWER than the minimum. Added two more. Still below the minimum.

So.. where the hell is my oil going? I'm not throwing any codes. I'm not getting blue smoke. I don't see any residue at the VCG or Oil Filter housing gasket. It's like it's going right through the engine, but it's not showing up on the drive way or anything.

I'm super confused... but need to get this fixed asap. I don't want to blow up my car!

What is the actual oil level, not the 'virtual' oil level, condition sensor indication? It sux to not have a dipstick.

Youíll have to drain the oil. Iím concerned at this point that you may have an overfilled condition.

+1 on this. I would drain it all overnight and do a complete oil change with the correct amount.

Agree, probably a bad sensor. Drain at home (and measure the oil that comes out) and refill if you can, or tow it to your local indy.

Are the sensors a replaceable part on F30s? I can't seem to find one on ECS. I can find the old ones... but not for F30/335i.

I am getting next year fun car as daily driver. I was always BMW guy, but starting to strongly lean toward Audi S4 and oil dipstick is major reason for that.

It's important to also think about system messages. The engine could either leak or burn oil. It would be difficult to lose that much oil with no trace. No more than one quart should have been added before tracking down the real cause.

There used to be a PuMA flag on replacement oil condition level sensors. From mine,
"Before replacing the oil level sensor always note PuMA measure 29604954!"
