Bad O2 sensor
Is it possible for the Check Engine Light to be triggered by an overdue
oil change? For example: diriving around with a red oil light for 3 months in the cold? Just wondering. And will an oil change fix the problem and make the light go off? Or does that sensor now have to be changed? Thank you in advance. |

Why would you drive for 3 months in cold weather on dirty oil?

The red oil light is an 'advisory' warning, and can safely be ignored for three to six months of average mileage driving. If you change the oil within in the next eight to ten thousand miles or so then you'll be inside the BMW approved red oil light warning window. Therefore, depending on what mileage you do, you should make plans to do an oil and filter change before early next year. Modern engine oils are designed to keep working well after the red light comes on. Don't let the car makers convince you otherwise. They're "in bed" with the oil companies, and they just want you to buy more oil. It's a bit like the battery companies telling you that you need to put a new battery in your smoke detector every year, when we all know that the battery's good for at least five years. -- Dean Dark |

I didn't. I lent the car to my brother and he did and I have thanked
him for it. But is this the cause of the CEL light? And will an oil change fix it? |

The Check Engine light indicates a error in the computer control system. It can be many things. You need to have the error code read to see what the error is. |

If around 100k miles or moire, then it is quite likely a tired sensor. But those puppoies aren't cheap and (depending on the model and year) there are multiple (up to 4) of them in the system. Might be best to have it diagnosed before thowing > $400 in O2 sensors at it, UNLESS it is due to have them replaced anyway. ISTR that 100k miles is the magic number in most cases. -Fred W |
