"Service Engine Soon" - light is on :(

[Fingers]

Was driving home from church today when this light appeared on the dash of my 2001 BMW 330i.

Current issues that I am working on...

1. Replaced Brake pads about 1500 miles ago and have yet to replace front left brakepad sensor.

2. Grinding noise that appeared after new brakepad installation and after painting brake calipers.

3. Have had to put more antifreeze in twice in the last 4 weeks and noticed a drop or two of liquid under my car everday in the garage. (thought this was because I used my AC while heating my car to keep the moisture from appearing on the inside of my windows)

I put more antifreeze into my radiator, didn't help, checked oil, it's fine. Don't want to take it to the dealer and get charged a couple hundred bucks for them hooking it up when I can tap your brains for help. Thanks in advance.

Go to the nearest Checker, Autozone, Kragen, auto parts store, etc. They can all check the codes for free.

:thumbup: Welp thanks for the reply, I read some of the other forum posts on other websites and checked a few things and found out that readjusting my gas cap was good enough for the sensor. I guess the sensor gets thrown off by the colder weather and how the gas pressure is affected by the weather. So no trip to the garage yet for me. Thanks!
