Hello All,

I just purchased a 04 530i great car love it so far, but I noticed something crazy thats happening with the mpg meter. If I'm driving in traffic and start to accelerate the meter will obvisously go towards 12 mpg but then when I relase my foot from the gas it begins to go towards the 50 mpg side and then suddenly its moving back towards to 12 mpg again without me pushing the gas at all..... any one have any clue whats going on???

Next, my brakes produce a crazy amount of brake dust. I used to have a 3 series that did the same thing. Is this just a standard thing with BMW's or am I doing something wrong?

Yes--lots of brake dust is normal on these cars (most cars with high performance brakes, actually).

Can't help on the MPG gauge. I find it useless (so I put my V1 remote display in front of it...).

Thats an MPG gauge? I thought it was a metronome.

Yes...and it's as useful in the car as a metronome...;)

Agree on the brake dust. Is there anything out there that you can apply to the rims to limit that problem?

I really like the instant mpg meter. It's a pity of all the BMWs I have, its one of those that doesn't have it. So I always have to go thru the diagnostics to get the digital readout :rolleyes:

Get some RejeX--nothing will eliminate brake dust buildup, but it will minimize it, and make clean up much easier:

And get a California mini duster to clean the wheels between washings:

^^^ or just replace the soft dusty pads w/ some Hawks like I'm about to. I have them on my 350Z Roadster and they don't produce hardly any dust at all.
