Help with oil sensor problem please
Hey guys,
My oil quantity sensor went south, I purchased a new one and installed it during an oil change, The car wouldn't recognize the new oil quantity sensor and the msg In idrive said "oil quantity unavailable" so I hooked up my OBD scanned and although it showed no codes I did an erase anyway. Now the car recognizes the sensor ("oil quantity unavailable"msg gone) however even after the engine gets to full temp the "measure oil quantity" stays shaded and wont allow oil quantity to be measured. Any ideas ??

Howdy all. I'm having similar problems with my 2011 X3 28i. (Hey Marty in NY! Thanks again for your help with the transfer case/wheel speed sensor.)
So, I dunno. I have no obvious problems with the water pump (just running after I turn the car off... no overheating), the alternator (no charging issues) or the IBS, as far as I can tell. I DO have problems getting a reading on my oil level. The iDrive says as much. But the Foxwell shows no specific oil level sensor fault. And the diagnostic procedure from the blog doesn't single out the oil level sensor as the cause of the BSD data bus communications fault. Any thoughts? Is this just an obvious problem with an obvious solution - change the oil level sensor? Is the CD9304 fault and the proposed diagnostic a red herring?? |

BTW, does your oil temp gauge read normal? Read through this thread, I wonder since you have a 2011 28i, if your software never got updated.. .. https://x3.xbimmers.com/forums/showthread.php?t=612101 . |

Hello again Marty! My oil temp is reading fine even after hard driving. Below 250 and I'm down in south Florida so there's plenty of heat.
Yeah it's weird that the obvious signs (iDrive) point to the oil level sensor, while unplugging the sensor doesn't clear the bus fault. I've pulled the plugs out of the alternator, the IBS, and the oil level sensor to try and clear it. No dice. The only things left are the water pump, whose connector is really hard to get to (can't get around the brace, hoses and sway bar), and the DME itself. Really hope it's not either one of those. I hear the water pump working and water moving through the tubes, and I'm having zero engine temp problems. Could the pump still be the faulty part? If it is faulty, could it cause my oil level sensor to go "inactive"?? Good investigation on the software update. Given that mine's a 2011 and I just got the car I have no idea if it was updated. But maybe it's the culprit. Doing what I can not to drive this thing in to the stealer and have them plug in a computer for $400... |
