Check engine light came on today

I was wondering if I should just take it to a shop to get it checked or should I get a fault code reader. I was leaning more towards just getting a code reader, but not sure what kind to get, so any input would be greatly appreciated.

If your car is a '95, it's OBDI and you'll need an OBDI scantool OR you can check the codes by diong the "stomp" method(search the forums for "stomp" to get a better explanation). If your car is a '96 or newer, it's OBDII and you'll need an OBDII scantool. The port is located in the driver's legwell under the dash. It should have a black plastic cover with "OBD" embossed on it.

Thnx, I have a 98 318ti, do u have any suggestion on a brand I should get? I was looking at peake research or would any brand be ok?

Just about any OBDII scantool will do the job. Some are just nicer than others. The cheaper scantools will only read/clear the numeric codes, while the nicer ones will give you a description as well as "Live Data" including AFR's, sensor readings etc. I use an Innova 3130 which cost about 140 bucks. I like it because it has a backlit display and gives live data, which comes in handy when troubleshooting at night. Another cool reader is called the ScangaugeII. It's designed to stay plugged in and gives you a variety of functions. I think it even gives you MPG info.
