Q: My 2005 X3 w/120k miles; running fine; service engine soon warning light came on on 2005 BMW X3

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Car still shows no issues...What is it? If simply emissions, or nothing immediately critical, how do I turn it off?

Hard to say without any data such as fault code it could be anything... Hope you follow up with some more data or visit your local service station then post up their findings. Best of wishes

you will need to have a scanner to turn the light off as the newer vehicles have a computer with a keep alive memory. this means that when the battery is disconnected it will not clear codes on the DME control module. Most shops will perform the scan test for a nominal fee
