Z3: Code P-1542
All - I'm going to have to take my beloved Z3 into the shop, and I always like to go armed with a little knowledge, which I've found I can get from this forum in spades! Here's the issue:
I have a 2000 Z3, 2.8 with about 80K miles on it. I started it up yesterday, and the engine light came on, as well as the ABS and EML lights. The engine went into limp mode. I had the codes read and I got a P-1542 (two of them, actually). The fellow that read the code stated that it was for "Idle Speed-Cont Veh-Speed" code, but BMW says "pedal position sensor electrical" code. Maybe that's the same thing; I won't claim to be much of an expert. Anyway, I read that it's possible that the throttle body needed cleaned, so I figured I'd do that before I spend money at a mechanic. It didn't seem to gunked up to me, so I'm not so sure about that as a resolution.
Also, when I turn the ignition on, before cranking the engine, I hear a whirring/hissing sound that I have never noticed before.
