    General E46 Forum
    Hey All, Long time BMW owner, first time poster. Title says most of it. I went away for Christmas break for 3 weeks and came back to find my computer (with the mileage, temp, etc.) blank (light still on, but blank). The car still works fine so I think nothing of it. Fast forward 2 days and I...

    This is the BMW E46's computer/monitor reset procedure. For those of who have the "service engine soon" light coming on frequently preventing you from getting the sticker, read this.

    General E46 Forum
    Hey, A couple months ago I posted a threat on my HID fog lights that were making things act up. I was told to pull them out, and I did. Things have been fine since, until the last week or so. Twice in the same day my whole cluster stopped working, and I just had to pull in/out fuse 43 to reset...

    General E46 Forum
    So I'm looking at buying an E46 330i (probably '03-'05). I plan on installing / upgrading to a Dynavin touchscreen nav. My question is, if the car does not already have a navigation system in place (along with the trip computer), will I be able to hook up any pre-installed wiring to get the trip...
  9. Computer/Instrument Cluster

    General E46 Forum
    Today I was changing out a bad fuse and accidentally pulled out a fuse that goes to the instrument cluster. Now a yellow "BRAKE" light stays on, the triangle with exclamation and counterclockwise arrow (maybe traction control) in the owner manual it's called the "ASC+T/DSC and ADB/ABX/DBC"...
  10. MDK issue leads to DME suspicion

    General E46 Forum
    Hey guys, I could use your help on this one. I have a 2000 323i 4 door with manual transmission. A couple of months ago I pulled away from a stop light when the EML and DSC lights came on. The MDK (throttle body) also was put into Emergency Operation 2, which allowed me to limp home at...

    This has been an issue for me for a While and I still haven't found out the cause. Every time I start my car the Trip ODO, MPG, Clock and MPH reset. I have checked the batter cable and all seems to be good. Has anyone ever experienced this? What things could I look at?
  13. 325i computer/sensor issues

    General E46 Forum
    hi, my 325i stationwagon, which was running perfectly up to a few weeks ago, has some (in my opinion) computer/sensor issues... On some days, the engine idles extremely eratically, and often cuts out. The torque seems to be impaired too, as i need to give it large amounts of accelerator to pull...
