    Hi all, just joined the site and have introduced myself in the introductions section.

    I am looking for some advice.

    I have had a dead battery now for about a week, due to a faulty hedgehog. I have ordered a replacement and now disconnected the faulty one until I replace it. I have charged the battery and all appears to well now, with the battery at least.

    The car has been parked out side in the hideous amount of snow and subzero teperatures we have had. Once I got the car started and running the Engine Deterioration in exhaust values symbol appeared and has stayed on. I have not had the car out for a run yet as it wont make it out of the parking space yet, but have had it running for almost an hour.

    Is the light likely to go out after the car has had a decent run?

    What has been the likely cause of the fault?

    Will I need to visit my local indy to have the fault codes read/diagnosed, or has anyone had similar issues?

    Just thought I would ask first as it has never been on before the battery had drained and its spent a week sitting in the snow and subzero teperatures.

    Thanks in advance for any assistance offered.

    Barry

    I wonder if this light has come on because of the low battery voltage the ECU is receiving due to the hedgehog problem?

    Perhaps taking the car for a run and then getting the error codes reset would be a good starting point. If the car was running well before this, then I would suspect that it will "go away" after the current problem is addressed.

    The hedgehog is currently unplugged until my relacement arrives, to stop it from draining the battery.

    I am hoping it will clear after a good run, but will the light go out, or will the fault be stored and the light will remain on?

    Should I have posted this in the E39 section? I would hate to annoy moderators by posting in the wrong section with only my second post.

    Thanks
    Barry

    You know what mate, I am a moderator and I think that it is in a good place TBH as you may get a bit more "coverage" here

    I will PM a couple of folks on the forum who may be able to advise you better than myself on your problem

    There are a couple of scenarios that I have come across that will bring up this light. First was a split in the throttle body hose and the other was a faulty spark plug. Maybe you should have the fault codes read Barry.

    When I can get the car out of the street, I will give it a decent run and then I think that is exactly what I will be doing.

    Just thought I would ask the question, as there a wealth of knowledge out there and generally no fault is a new one, it has always been experienced by someone else.

    I was just curious to see if the fault was connected to the dead battery or possibly with the fact the car has not turnred a wheel in over a week, and sat in all the snow and freezing temperatures. If it was connected and sorted itself out after the car has been used again, would the light go out, or is the fault stored and the light remains on until I get it cleared?

    Thanks
    Barry

    The codes need reading and clearing ideally, if it was something like a camshaft sensor intermittent fault then the light should extinguish then come back on every so often when driven.

    Just an update for anyone who was interested, or has had similar issues.

    We have success. After three days of having the car running at 3000rpm, for about an hour a time, the light has gone out and more importantly stayed out.

    It would appear as though it was either the battery had not fully charged, and now has, or it just took a while for everything on the car to defrost. It has barely been above freezing in my neck of the woods for about two weeks now, and the car hardly gets any of the little sun we have had, where it is currently parked.

    Looks as though I can spend my hard earned cash on a Carbon Roof spoiler now, rather than a diagnostic and repair. Might hold off for a few more days though.

    Thanks
    Barry
