Help- Check Engine Warning Light Comes On

[dori34]

i noticed this morning that the check engine light wouldnt turn off.

the car doesnt have rough idle and it still drives the same so it aint the coilpacks - ive already tested them anyway. i had this problem a few months back but when the light came on, the car had really rough idle and i pin pointed it down to one faulty coilpack so i replaced that so i dont think thats the issue.

Does anyone know what it may be? the car still performs perfectly normal but im just paranoid and rather the light be off.

Thanks for any help in advance

check oil pressure, hopefully it's not an oil issue...

light went off after an hour, very strange.

according to the standard oil pressure gauge, its normal like b4 the light was on. didn't notice any abnormal readings

it wont be oil pressure, there is a separate warning light for it. the ecu is throwing and error code, run an ecu diagnostic or get someone with consult software to check them for you.

when the engine check light lit up in my car it turned out to be the O2 sensor.

i know on 33's theres a way you can do it with a paperclip but im not sure which holes u bridge them together, does anyone know??

i've always used the consult link to my laptop but this may be of some use

i don't know if the paperclip trick works on the R32

mines a 34.

thanks for the link but ive already seen that.

probably just buy a consult plug & unit off ebay.

Cheers
