I have a 328I and occasionally the check engine light will come on. I
believe it is a fauly sensor since the light normally goes out after a month
or so however my card needs to be inspected this month. In NY your car will
not pass inspection if the check engine light is on. Is there anyway I will
be able to get the light turned off any earlier then the cars normal cycle?
What year is your car? E36 or E46? The light can be turned off with a
scan tool, but often times a code will be stored for a drive cycle before it
turns on the light. If the inspection station reads codes and finds one
stored you may fail anyway. Also, if the code is emissions related and they
analyze the exhaust gases, they will fail you that way, even if the light is
not on. It would be in your best interest anyway to find out what the code
is since your car is trying to tell you something is wrong. You're probably
going to need to get it fixed to pass so you might as well find out now.
Check you fuel filler cover (gasoline cap in US speak?) make sure the
seal on it is ok and you've close it tightly.
If the gas cap leaks, it fools the computer into thinking the gas tank
(fuel tank in UK speak?) is leaking. Tricker the Check Engine light.
