Service Engine Soon light has illuminated 3 times over the past 6 months. Each time taken to BMW service center. Illuminated again today after battery was re-installed. Any trouble shooting tips are welcome.

On my 2001 Z3 I was told that their are only a few things that can cause this (like on the e30's).

When I was having this problem the dealer kept asking me if my gas cap was tight. After the 3rd time it happen I began checking to make sure the cap was as tight as can be after buying gas (and before starting the car).

Haven't had the problem since.

Question: What did the dealer say the computer readout was when they plugged the car in? Like I said the Z3 doesn't have a huge code listing. Just 3 or 4 things that could cause that light to come onů like; Oxygen Sensor, gas cap, etc.. again, like the e30 model.
