Check Oil Level Warning
Is this a common problem? Is it a sensor failure, or is there actually something going on that I need to look into? On a related note, I do have a really stupid question. The dipstick in the 4.6is is different to every other BMW I've owned. It isn't really clear on how to read it, and there is nothing about it in the owner's manual. Can someone provide clear instructions on exactly how to read the stupid thing? Maybe there actually is an oil level problem and I'm just misreading the dipstick. According to the manual, the sump holds 8.5 quarts, which is exactly how much I put in after draining the oil. But I've been losing and topping off so much while chasing leaks, that it's impossible to know exactly what's in it now.

This is happening to my wife's 06 X5 3.0i. Sometimes the SES light comes on, sometimes its just the message in the instrument cluster, and sometimes its both. Not sure what is going on...

From what I read you have to have the vehicle to its full operating temperature, stop the vehicle and make sure its on a level surface and wait a few minutes give and take and check the dipstick. Now if its still showing high on one side and low on the other the lower of the two is the actual oil level in the engine. Fun isnt it!

The message comes from one of two things, the oil level is low, or the sensor that detects the oil level is failing. On the E46, this is a common issue that is nearly always caused by the oil level sensor. I don't know that the E53 has the same issue or not, but you are describing the affects of a failing/failed sensor. It's pretty easy to replace on the M54 (3.0L engine). Well, it was easy on the E46, the E53 has the pesky deep oil pan that the E46 does not have. Having said that, the sensor is in the bottom of the pan, so replacing it on the E53 should be simple.
As has been pointed out in Post #4, the level is okay if it is anywhere between the two marks. |

Thats not the problem. Im pretty sure he knows that as thats pretty standard on all makes and models. Its the V8 engines where they dont read level and on the actual dipstick one side is higher than the other is the problem.

Somebody linked the SES light with the low oil, this is an error. Low oil level is not monitored by the ECU, and does not trigger the check engine (SERVICE ENGINE SOON) light.
If you have random low oil messages and the oil is not low -- below the bottom mark on the dipstick -- then the sensor is at fault. If you have a random SES light, then you have something else wrong also. |

Thanks for the tips!
wpoll: The 4.6 dipstick does not look like the one in the photo. It looks nothing like any other BMW dipstick that I've seen. I also have an E38 740 with the M62 V8 and it's not the same as that, either. For whatever reason, the 4.6 uses a unique dipstick, and there are no clear markings on it. The oil level sensor for the E53 is the same as the E46. It's not that hard to get to, other than the need to remove the aluminum skid plate to get at it.
