Bad Gas, "Service Engine Soon" came on.

[Tensor]

The "service engine" may came up if you filled her up with the motor running. A simple OBDII diag dongle can clear it.

Try this: http://www.xoutpost.com/articles/x5/e...ts-bmw-x5.html You might also want to change the oil and filter.

Skip the above article, it refers to the service interval lights (when to do an oil change) and not the service engine soon light (which is a fault indicator).

Using regular gas by itself is not a cause, unless it is really bad, less than 87. Using dirty gas can be a cause.

Make sure the gas cap is tight, a loose gas cap is the most common cause of the SES light. If it doesn't go away by itself in a day or so, take it to the dealer. It can often be a sensor, or something similar, and it is difficult to diagnose without the code reader.

You are correct. It didn't read the article before I posted it. The title on the Home Page in wrong.
