  3. E39 (1997 - 2003)
    Hey all, I'd like to start off by saying I am new to the forums because I'm new to BMW. I love my car and it had very few issues at the time of purchase. This one was caused by a dumb decision by myself capped off by a detailer who messed up (going to be talking to him next week in person)...

    Hey guys, Firstly I drive a 1996 e39 bmw. I have a few problems I need help/advice on fixing, I'd prefer to do this all myself however it's my first bmw and basically my first car so I'm unsure of how to go about it. Number one: I have an airbag light permanently on on the dash. Number 2: just...

    hi, new member to the forums although I have flicked through them quite a bit before just never posted anything... Anyway, I've searched for the answer to this already also though the forums. But how do you turn off the ASC in a e36 I've heard things from press once, hold for 5 seconds or hold...

    Recently I had the rear shocks replaced on my 2000 323i sports wagon. I was a driving on the interstate for the first time since then, when the back of my 323i wagon shuddered hard and the ASC light came on. I pulled off and turned off the car. After restarting, the ASC light was off, but after...

    We have had a bit of a cold snap here in MN. On the day I started having issues, it was around -15F. I have been seaching the forums for a couple hours and haven't found my issue here yet. I started the car and the engine would keep reving from 1200-1800 RPM and then the EML, ASC, Engine...

    My Touring is a 528 with a build date of 12/98. This past week I got the dreaded "Bifecta". In my reading and research, I ran into the question of which stability control system does my car have? The button on the console says "ASC", but if I look at the diagrams on REALOEM the hardware shown...
  10. E36/7 Z3 (1996-2002)
    Hey everybody. Can someone give me an idea what could be electrically wrong before I take my car in to be serviced. The first thing that happened was my windows would not go down in a continual motion. Just bits at a time. Immediately after that, the truck lock would turn but not seem to...
  11. E36/7 Z3 (1996-2002)
    Hi Guys, I have a '99 M Roadster which I modified recently by swapping out the second ASC throttle body for a non-ASC intake boot. As part of the modification, I also removed the motor which actuates the ASC throttle and the sensor which reads the position of the ASC throttle. I have taped over...

    Hi guys, I have a little issue with my 2001 BMW Z3 3.0 Roadster. So, this is the problem; I randomly get the ASC and ABS warning lights on my dashboard, sometimes I get this when I'm driving on bad tarmac but sometimes I start the car and the warning is already there or even in good tarmac...
  13. E39 (1997 - 2003)
    ANY and ALL help or advice is greatly accepted.. I have a 98 528i (7/98) build date. The asc light is constantly on and will not go off. Also, there is a significant loss of power and "rougher" shifting points. Tranny is NOT in limp mode, but will not downshift, but will however shift down 2...
  14. E36 (1991 - 1999)
    Sorry for the new post guys. I first called it a "DTC light" and it's actually called an ASC light or ASC-T light. Need advice on what to check for. Assume I'm a generic brand experienced car mechanic, not specifically familiar with BMWs. I'm calling it the right name on this new thread, hoping...
  15. E46 (1999 - 2006)
    Hi, Just bought the BMW 330CI. I notice that when I go around a corner and am going down a bit of a hill, that the car actually accellerates (I see the RPM increase and the car starts to move faster), and meanwhile I have my foot only on the brake. Is this part of the traction control system or...
  16. E39 (1997 - 2003)
    Hello to all, I did a front brake job on my 98 528i two weeks ago and since doing it I have been having an issue with my ABS warning light coming on and immediately deactivates the ASC. Completely intermittent, comes and goes. I do know the new brake sensor is not working as I still have brake...

    I just bought a 1999 BMW 3 series coupe, and the traction control (ASC) warning light was on constantly, then i restarted the engine, and it disappeared. the anti lock brakes (ABS) also came on, and disappeared when i restarted. the airbag warning light has stayed on constantly since i bought...
  18. 7 Series - E38 (1995 - 2001)
    Hi Y'all, Anyone out in beemerland know why the ASC light would come on after replacing the MAF, Cam position sensor, and the ignition coil pack on cylinder 7. The rough idle problem is history since these changes but now she is having some issues with starting! I fired her up this AM, she...
