    A problem with a AC Schnitzer Z3

    Hi its dilinger,

    I have a problem that i want to share with you. I trust you have some technical knowledge so i though, what the heck .

    Yesterday i run out of gas with my other car (its a BMW Z3 Ac Schnitzer 2.1 LT) . So a friend brought me gas and the car could not operate well. I could barely start it. The noise was very heavy and i called a mechanical. With great difficulty we managed to drive the car to the service dealer.(thanx god it was close -half kilometer.) So when i brought the car there, it seemed that is was working only with two cylinders. After we run a diagnosis test we found out that the engine flange was burned. How the hell can this happen to a car with 70,000 km only?? And moreover how can possibly be a coinsidence that it happened when a run out of gas. Not to mention that i had never seen a high temperature warning.

    Please share your opinion with me
    Thanx in advance!!

    Best regards,

    Dilinger

    Running out of gas can suck debris that is floating in the bottom of you gas tank into the fuel system. If that gets past the fuel filter, which it can, it can damage your injection system. I did that once, some years ago, in a Volvo, and had to replace the fuel injector.

    Beyond that, can't imagine how it gets into the cylinders, and I don't know what an enging "flange" is. But I'm not a mechanic or engineer, just a driver.

    Sorry to hear your problem. Let us know how it works out.

    Dilinger,

    When you say that "engine flange was burned", does that mean that the cylinder head gasket had blown?

    If so, I don't think that the problem arising at the same time as you ran out of fuel was a coincidence. The engine might have been running on a lean mixture for a while, due to fuel starvation, and that could cause local overheating around the combustion chamber. Since the overheating is "local" - only in the metal surface of the cylinder head - it would not show as a high water temperature on the temp gauge.

    Just a guess.

    Re: A problem with a AC Schnitzer Z3

    the problem is the entire car. Z3 = yuk

    i've seen wet sponges with more structural rigidity.

    Re: A problem with a AC Schnitzer Z3

    All our new cars are equiped with OBD2, diagnostic system with "loop". It means that your car is equiped with at least 1 lambda sensor and can immediatly know when you run lean or rich. I am 200% sure of that.
    When such a problem appears, there is a "default problem" stored in the ECU with a warning on the dashboard.
    So, for me the problem could be the following:
    1. your ecu was reprogrammed by AC Schnitzer and they blocked some parts in the ECU system, not allowing any warning. They do that sometime, I am sure (to avoid that the warning appears for nothing in the dashboard and be annoying for the driver and for the "tuner")
    2. if it's the gasket between the cylinder block and the engine head, it was replaced by AC Schnit. to reduce the compression ration. Maybe this part was not appropriate or adapted for the engine, or has a default.
    My advise : contact AC Schnit. and tell them the problem.

    Re: A problem with a AC Schnitzer Z3

    Excellent points jecey.

    I am very curious about this "flange". If it is the head gasket, could that be replaced for 800 Euro? When I first saw that I thought it was too cheap for any serious engine work, but maybe it's OK for a head gasket, which would mainly be labor expense.
