[attachmentid=3662]Hey fellas, the infamous light has not returned so i drew a picture. Correct me if I'm wrong but it is my belief that upon turning the key to the II position all of the instrument lights should come on and the computer does an onboard diagnostics or "system check" before ignition begins in the next position. The box in that space has never lit up before-not position I-not position II- not upon starting.The strange thing is , for the short duration that this light entered my life it came on upon position II with the rest of the lights in the system check mode.This has never happened before and now once again is just a dead space. The car started as normal with the ABS and TRACS lights staying on and then upon hitting the brakes "POOF" the unknown light was on. I am going to have the hydraulic unit rebuilt to hopefully cure my ABS. Has anyone else seen this light before?

old topic but since its already been bumped....
yes this is def check engine light for euro cars as it is the one on my car and also is in my manual.
sean

this is the EES right? something to do with fault on the engine fuel or ignition system (says in the manual) this also means that the engine does not meet exhaust regulation?

just to cut things short mine is on. half life sign is the check engine for eu V's right?

but when i got home this evening the light turned off. maybe something to do with the brand of unleaded gas i use? BTW engine starts normally.

The lambda light could be triggered by a few possibilities. And after a while, they will reevaluate the problem, and if the problem has been taken cared of, or is fixed, then after a 'few cycles', the light will go off. But the message will continue to be stored, until you manually delete it. Which is why it is best to attack the problem when the light is still on. Cause, if you keep accumulating the error messages, you wont know which is the actual problem once you retrieve everything down.

THanks.

I think My Man Greek asked you  a question earlier about the year of manufacture for your 850.

The reason is just that pre1995 manufactured 850s run on the OBD1 system, and you can read/delete error codes from the small black box located between your ECU box and the front headlights.
But post 1995 850s are OBD2 system, where you'll need a code-scanner or a scan-tool to read the codes and delete etc. The usual typical case is that the more expensive the reader, the more functions it carries. Try googling up if you want to buy any.
Aside from that, either go to the accessories store (Greek mentioned Pep-Boys?) or the dealer to get them to help read and delete the codes.

Let's hope its just something small.
