If You've got a check engine light on on Your 2018 BMW X3, You might be wondering what caused it. The most common reasons for a check engine light on a BMW X3 are a loos gas cap, failing oxygen sensor or issues with the transmission. The gas cap becoming loose or degrading is one of the most common reasons for the check engine light to come on. A oxygen sensor failing can also be one of the most common culprits of a CEL. If You want to check the codes on Your computer, I recommend buying a OBD II scanner tool. A OBD II scanner will help You determine what it is causing the light to come on.
