Question about 2000 BMW Z3

Exhaust emission warning light

Yesterday a warning light lit on my Z3 - "exhaust emission values have deteriorated" it says in the handbook. 2 days before I changed the plugs to Denso Iridium IK20 and the car is running better than ever before, no noticeable misfire. Can I still drive the car with the waring light lit? Can you suggest any reasons for it being lit, and does it need to be reset via the OBD11 (ie by a dealer)?
Thanks

    I have the very same problem, the Exhaust emission warning light came on a few days ago, it’s a BMW 5 series and it’s not due a service for a while yet.

    Anyone know what causes this and what the remedy is?

    The car drives fine with the warning light on I will be bringing the car to a garage soon but would like to know what to expect.

    My Z3 is doing the same thing, however as i have a rattle under the car, which sounds as though it has something to do with the exhaust. I take it that this has caused my exhaust emmissions light to come on. t he car also seems to be loosing power, especially when i first start it up, it dosen't want to pick up when you put your foot down.

    I am having the same problem on my 5 series. The warning light came on about a month ago and stayed on for about 2 days - I spoke to a mechanic who told me not to worry about it. The light has come on again today. Does anyone know what it could be??

I posted a couple a months ago that I was having the 'exhaust emmissions' light coming on my BMW 520i a couple of months ago......... I found a local BMW specialist who initially could not find the fault. While carrying out an inspection 2 last week he found that I had a tear in the air intake pipe. He strongly believes this would cause the light to come on.

I have had it replaced today so will know in due cause whether this is resolved. So far so good..

    Forgot to mention that he had to replace the same part on a Z3 a couple of weeks ago..

  • Vickas Nov 08, 2008

    See my comments below dated the 15th October........ Since I have replaced my air intake pipe I have not had the warning light back on :-) It only cost me £70 to get replaced by a BMW specialist using genuine parts!

The following 2 warnings came up in my mini one 04 reg deterioration in exhaust emission values and fault in engine electronics What could be the problems please


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

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.

I have a BMW Z4 2003 2.5 with the exhaust emission


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

Lambda probe fault possibly


I bought a 2000 polo 1.4 yesterday after having an MOT. The warning lamp came on today but the car is running fine. Whether its the Lambda sensor or just the light itself is a common fault, I think garages turn off the lights to get it through the MOT then they come on again in a day or two!

The engine exhaust emission light on


it sounds like the oxygen sensor, air mass meter. check the crankcase breather pipe behind the engine ( cracks, common problem), it would be wise to have a computer diagnostic done, it will save u time and money

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.
