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.

Good luck on the repair.

My Mini Cooper's engine light is coming on saying engine deterioration in exhaust emission values. How can I fix this and will it be expensive? thank you

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.

A light came on the dashboard. I checked it in the book and it says that the exhaust emission values have deteriorated.

Het it put on an ODB2 reader, it is likely to be an O2 sensor going wrong or something not too bad.

BMW 318iSE (1999) engine warning light

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.

Emission light comes on

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.

Engine/exhaust emission

What symptoms are you getting when driving the car, if any at all? Sometines a loss of power can be an exhaust problem or if you find the car is revving on its own accord when ticking over this points to a sensor problem. All depends on what the problem is the price, this can actually be cheap to repair, but also expect to pay over £70 for the initial diagnostics.
