View Full Version : More useless Trivia re: E46

Guys,

This may be old news, but I was at the dealer having some options programmed on my car (picked it up Friday), and mentioned some condensation inside the turn signal lenses ('02 330i). Anyway, chatting with the mechanic, he pointed out that the turn signal/front parking lamps are a single filiment bulb that perform the function of a traditional dual filiment turn signal/parking lamp bulb.

He said that the electronics of the car vary the power to the bulb to get both functions out of a single filiment. I did notice that when the parking lights are on, if you look closely at the bulbs, they seem to "pulse"... He said this is the computer metering out a smaller voltage to the single filiment bulb. I then noticed tonight that when the lights are on, and I activate the turn signal, the unit blinks as if no headlights are on at all - i.e., it blinks "on-off" instead of "bright-dim" as on most cars when the lights are on.

So, this is probably useless info, except for the following:
1.) the mechanic noted a lot of folks come in with failed bulbs/fused connectors due to this unusual set up, and
2.) leave it to BMW to over engineer a parking/turn lamp with computer controlled voltage regulation instead of the traditional 2 filament bulbs. I predict when the E46 becomes a well used "collector" car, the market for replacement front turn signal connectors will be huge - start hording now.

BTW, I LOVE this car!

PS: I got to watch them use the Siemens wireless car programming touch-pad thingy - very cool!

Does that go for ALL E46's?

I don't know... mine is a 2002, but I'm guessing so. Just thought it was very interesting. I like weird gadget trivia like this.

I guess you can tell if it's the same on another year E46 by looking at your front turn signal/parking lamp bulb - if it's a single filament but performs both "dim and bright" functions, it would be the same.

Yeah, the unit I saw was similar to that, but the screen was much larger. The mechanic showed me where the wireless transmitter was on the wall that talked to the yellow box thing they plugged into my car. It was all very high tech and touch screen cool.

oh that looks like a fun toy.

Do you get one of those with every Bently's :)

I WISH!!! I went with OBD-2 (http://www.obd-2.com/) to access the codes.

That thing's looking very much like this one. It's the Siemens Simpad SL4. Very funny to use and great for internet.

obd-2 looks cool.

That and that simpad would make a great combo. We should get NCC BMWCCA to provide one to its member on a loaner basis.
