    I dont have a owners manuel for my 2003 bmw 330i,But my check engine light came on and stayed on until i took it to this shop in victorville,ca for another problem(a black resivour box was leaking coolant) and so i went to pick the car up after two days an my light was off i ask them what did they do? The guy said they twisted my gas cap! and every since then my check engine light has never came on again-I thought it was something wrong with my emission, So i have a low coolant light that comes on every so often an i put water an coolant in the radiator-do i surpose to put coolant in the radiator? there his no plastic box that i can reach to put the coolant in,will this action hurt anything later?

Check engine light just came on. Oil ok. could it be caused by a dirty filter?

The check engine light is triggered by trouble codes which means something is wrong with the emmissions systen, transmission, motor sensors etc. A dirty oil filter will not trigger a code. You need to scan the car with an OBDII scanner to get the codes. Once oyu have the codes post them here and we can help you. If you don't have a scanner you can take the car to your local auto parts store, they'll scan for free and give you the codes.

Engine trouble light coming on 2003 jeep gr. cherokee

If the light is ywllow, it's emmissions or some sensor. You can drive to a service center and have the codes read. If the light is red...STOP!! and check engine oil. DO NOT drive further!! Have it towed in for service.

Sevice engine light is on.

Both Codes show an Emission Controls problem - very likely a large leak. Give it a really good visual and look/listen for a vacuum leak or hose off in the emmission system.

My engine light on when engine is running the light that is on looks like a little engine .

this is an MIL lamp (malfunction indicator lamp ) which is tripped when the engine computer detects an operating parameter that is out of spec...there are many inboard and outboard items monitored which could cause this indicator...some items are extended warranty covered through epa emmission laws and some even up to 10 yrs 100 k miles so it might be advantageous to have dealer diagnose in the event of a covered item...good luck

possably a vacuum leak. the check engine light comes on with an emmissions issue, ie vac leak, and it will not allow the cruise to work. once the error is fixed, your cruise should work properly again

Check engine emmission message

the emission system on any car sold n the USA is tested and certificated by the EPA to not pollute for 100,000 miles, these systems include the EGR (exhaust gas recirculation) system, the fuel vapor control system, the catalytic converters, the various sensors on the engine such as lambada sensors and engine temp sensors plus many others
