That was awesome info, you're a god-send.
I read somewhere that, two things:
The Multifunction Steering Wheel" code has to do with the Cruise Control, which would make some sense since I use it ALL THE TIME. So, I'm guessing a quick reset would do the trick, since I haven't had ANY problems at all with it. (and the stereo is stock)
Two: The Sec Air System codes, have to do with the O2 sensors, and I've had a strong suspicion that my 02 sensors are bad since, one: the 100k wasn't done on this car. and two: I've been getting lower gas mileage as of lately, and I'm thinking it's the mixture.
correct if I'm off, or wrong on these.
As far as the Cooling system, yeah, I'll probably end up doing the whole thing. I've read about changing the entire system at 100k, for E46s, so, it doesn't sound like a bad idea. Especially since I'm having to buy antifreeze almost like gas.
This was the second Diag, and the camshaft sensor came on both. I don't even know what a camshaft sensor is or does. ??
The gas cap thing. That came up twice too. Are we talking about the actual gas cap, where I go and pump some gas? That little thing that I could get for like 10 dollars? The mech told me, and I was surprised, because he made it sound worse than it was. I'll just get a new one then, and put it on, but I don't see anything wrong with it? Any way I could fix it, or do something about it?
So, as far as I can see, nothing was replaced in this car. Which is a good thing in that everything is original. But it's bad in that for beemers, lack of maintenance like this is not necessarily a good thing as we all know.
This is my second beemer, my first was a E36, 92, 5sp. This is all too reminiscent of those times, but I bought that car the same way.
This has taught me a VERY valuable and general lesson. DO NOT BUY BEEMERS from dealerships, since these cars are usually not maintained like a Beemer enthusiast would. Next beemer I buy, which I plan on making it an E46 M series, will be a private owner...and I'll make sure to check that he has treated it like it was an offspring.
