I was driving this morning in my car and every thing was running sewwt ,then i noticed the engine management light had come on.the car is still running the same as normal but the light wont go out.i checked to see if the lamber sencors had come loose or some thing but couldnt see a problem..does anyone have any idears as i was a little worried.

What have you added recently?

[fozworth]

Nothing mate ,but dont know if ive loosend a conection or something .

always come on if its eml light its an ecu issue if its the one above its an emissions issue. bmw can turn them off quite easily (about £40 + vat) as can any garage with a code obd reader (normally for cheaper) more often than not its nothing. lights can stay on just because the petrol cap is left open. these (not traction control etc) lights wont turn themselves off and can only be turned off by an obd reader. you can purchuse your own for circa £90 from people like mini mania.


dont panic too much.... these cars can be very sensitive, normally just need resetting. which light is it and do you have and what mods are on the car?

Mine came on, the car drove like on 2 cyl, then drove ok but the light stayed on. Dealer just changed the throttle body assy, now ok.

Had that many problems with this car, but I still love it,,what is it with the mini??

[fozworth]

the light thats on in my car is the one thats nearly at the bottom centre of the spedo.it shows a little engine sign in orange.i didnt have any clips around my throttle body to induction pipe but thats been like that for a few days and not caused a problem..as i said its running pretty much the same a normal so maybe there was a glitch and its sorted its self or maybe a sender is down like the lamba.but then wouldnt it run badly?hopefuly the computor will say wat sensor failed. wont it?

[fozworth]

Sorry clair just reread your note.Yes uts the one above ,so it must be emmision .What normaly causes that.and could it be some thing simple.

[Saad]

try leaving it for a while, then coming back and it might have gone away. My emissions light comes on for a few hours if I rev over 6,500 rpm

[Claire_S]

basically the same light as yours would come on on mine all the time. it was the lamba sensor, wich waas replaced at one point. in the end i had it taken out the system, having the setup im running it liked to trip it by a tiny amount. your car will run fun and you wont prob be doing any harm. if you go to bmw they will prob most likely reset it and clean the sensor to start with. also they will tell you if the car has ever been in for any thing similar etc on their system if you ask nicely. on mine it was somthing i learned to live with. its just bmw being overly sensitive

[fozworth]

Thanks claire ,i'll go to an indipendent this week ,get them to double check and reset it then go from there,but if it does it often i might go down the same route as you.

this is the exact problem i have on my 2004 54 plate MCS Convert...

Warning light came on and I took it in and Mini reset it, that was about 2 weeks ago...

This weekend the light has come back on, which I can't understand, as I have not been driving it hard, or anything unusual, and there's nothing that seems wrong with the car itself...

Anyway, it's booked back in as it's something that shouldn't really happen, so I'm hoping they will find something wrong...

If it is emissions though as previously mentioned, what's going on? Is my little S kicking out too much stink??

Any help or suggestions would be appreciated - cheers!

I have just been on the phone to Nick at Lohen, as the light on my Mini One is also illuminated. He thinks its due to the high flow cat on my new manifold. maybe one of the sensors has malfunctioned, but the car is booked into BMW next week. Part from the light the car runs great.

[Cooper S Dan]

i'm taking mine in tonight and expecting it back tomorrow, so will be update this thread with what they find! i'll be quite mad if they claim to find no fault again, if the light is coming on there must be an issue somewhere...

[minioneandrew]

I have just got a decat put on, my emissions light didnt come on for the 1st 2 days, then popped on when i was driving home on the motorway - clearly i know why it is on - but why did it take 2 days?

[MiniPetrolHead]

was it a noticable gain in performance with the de cat?

[minioneandrew]

Well as i had the manifold and decat put on at the same time...i couldnt tell you if there was a different from the decat....but ive been told removing the cat on most cars adds power - 6bhp or soomething? But the manifold and cat in general are brilliant...i have a milltek 2 . Might be 2 noisy for some people - but when u let it rev up in 1st it does sound like a rally car- all raspy . (to the mods i do 30 in 1st gear then stop there )

[Cooper S Dan]

Well... I got my car back on Friday night and they have fixed the problem. One of the sensors before the cat (it measures oxygen apparently) was faulty so they have replaced that and so far so good!

Unfortunate that they couldn't find the fault the first time!! But it's fixed now so...

[Cooper S Dan]

Another update on this, it was my oxygen sensor that went, and i use tesco's petrol: BBC NEWS | UK | Petrol retailers say fuel is safe

It seems the problem was caused by Tesco's petrol!!

Hi, I just got a mini cooper and I have a question:

when I turn the ignition the lights all come on on the dashboard, they all go out except the eml and engine management light.

when I start the engine the eml and engine management light go off, is this normal?

[r1_kde]

is the mini OBD or OBDii? and by the sounds of it some of you could do with a reader
