SOURCE: service engine soon light on
you need to put it on a computer to find what the code is such as on o2 sensor or a number of other things. once you know the codes you can fix the problem

the service engine soon light means a fault has occurred in the engine or emission system's electronic controls, it has nothing to do with any service you did in most cases, there are over 150 problems that turn the light on, to find out what the problem may be go to any Kragen Auto or Autozone parts store and ask them to run a OBD 2 trouble code test, IT IS FREE. then post the code back here for us to look at, which is also FREE.

you can buy a cheap scanner that will put this light out,i have a mechanic working for me that stands on the roof ,tweeks the radio and has one foot on the brake whilst turning on the lights and he puts out nearly every service light you can think of but he wont show anyone least of all me,but if it its a 99 model iam sure you can put the light out by using a 12v electrical screwdriver with the light inside and a cable comes out the end with a clip .then going across the pins on the special BMW connector block it will go out with the resistance of the bulb across it ,but ??big but ?does it have an OBDII connector or the round BMW type because we dont have OBDII on pre 2005 cars here in spain .Now we do and guess what ??its all encrypted software used ...makes me a dinasaur

I can see that you've done the right things, but something is still amiss... Mitsubishi says
A code P0421 may mean that one or more of the following has happened:
One thing to note is that many vehicle manufacturers offer a longer warranty on emissions-related parts. So if you have a newer car but it's out of it's bumper-to-bumper warranty, there still may be warranty on this type of problem. Many manufacturers give a five year, unlimited mileage warranty on these items. It's worth checking into.
