Computer problem
2003 BMW 525 6 cyl Two Wheel Drive Automatic 74000 miles
----------------------------------------------------------------
diagnostic on my BMW said,System too lean,bank 1 and System too lean,Bank 2.
I've read some info related to this issue,but,do you think it's a major thing I 'd have to worry for?
It is mandatory to take the car to the expert technician to provide the correct solution to a system too lean computer code or not ?
My car is running with no problem at all,actually the check engine light is off now.

thanks.

cordially.

There may be a pending code, but if the light is off, the issue has resolved itself.
