  Yes, your car is equipped with Motronic DME, Version M3.1 ...

  Turn the car off .. turn key to the ON position but dont start ..

  Now QUICKLY hit the accellerator to the floor 5 times and wait ..

  The Check engine lite will flash out a code like 1221 or 1444 ..

  Record the codes it flashes and send 'em to me .. I have the "chart"
  that'll tell you what the DME thinks is the problem ..

  BTW this works on ALL BMW's (in the US) from late 1988 MY on up..

  That is .. DME Versions 1.3, 1.2, 1.7, 3.1, 3.3, 3.3.1

  On 3.3 and 3.3.1 you only a second or so to start whacking the gas pedal
  after you turn the key ..
