it needs to go on a obd code reader/scan tool or suitable diagnostic equipment to help with this prob. could be lots of things, most likely lambda sensor faulty or catalyst fault. but could be other engine managment system fault like fuel pressure etc
You need to bring this to a pro, and make sure it's someone very familiar with Minis. possibly a bad converter, but could be a sensor or injection problem that is sending too much fuel down the line, making your post cat o2 sensor see trouble. Get after it quickly, and maybe you can save your quite expensive catalytis converter.
Sounds to me that the O2 sensors are sensing a problem with the emissions, or other emision controls have detected a problem that may not necessarily cause a driveability issue.
If you have emissions inspections in your area of the country, then I would have it repaired before the next inspection.
Have the OBD-II scanner check out the computer codes and descriptions by Autozone or Advance Auto Parts for free, or buy your own scanner for under $100 from Sears or Walmart.
it could be the ignition timing or replace your fuel filter and the pvc valve and the air filter. Have you done to tune up your car? if not, tune up your car. If you done all of these you will see the different. ok
Hi..
A few clarifactions pls...
Which Car....
Does it have a carburetor or a Multi Point Fuel Injection System
Diesel or pertol or Gas.
The most basic reason for poor emission is incorrect mixture of air and fuel.
if carburetor then you will have to get the correct mixture set . Its NOT a long procedure just adjusting 2 main screws.... But lat a mechanic do it.
If Multi point fuel Injection... then the injector needs to be cleaned This is a lengthy affair. Before opening this you could use fuel additive ment for cleaning the injectors..
Alos check if the manifold/ exaust pipe is not leaking from anywhere as this reduces the pressure and the burn is not total resulting in Emission..
There are fuel addetives that help clean the engine from inside.... but for that I would need more info so as to guide which addivive could be suited.
Regards

That sounds like you bought big problems. Oil ights indicate low oil pressure= BIG BUCKS. I would have a qualified repair shop check it out, A shop that specializes in BMW. If you are lucky, maybe the oil sender is just bad. They can also check out the Ck eng light. But the oil light is priority one.
The Exhaust Emission Light can come on if the car is driven slowly over short distances.It will not happen on cars driven at speed. A short trip of ten miles at over 3000 revs should reset the warning light,although it may not go out for a couple of days after you have tried it . Hope this helps and saves a bill at the local dealer. JK
it will not pass the test with the light on, and if u turn off the light they will know when they test it by testing/checking the system readiness function. Go to a Kragen or an Autozone they will run the test to see what trouble code has turned the light on, it is free, post the code back here. Oh have then reset the light after the test.
