knock sensor

hi im having some strange idling issues on my 1994 318is
first up my cars idle randomly starts to fluctuate between 500 to 1400 rpms when the car is stationary, after a few revs the idle calms down but soon it starts again. people keep saying icv however i had a new one installed just under a year ago?
my cars headlights / dashboard lights dim for a second when i try to put up a window thats already up. ive checked the battery, its fine also i checked to see if my alternator was charging, and its also fine.
i stuck my car on carsoft... heres what came out:
[code]201 Lambda Regulation A Possibly the tank ran empty, because of the fact that the lambda = regulation recognized a too fat resp. a too poor mixture. It ? could be possible that also other faults appear, which explain this condition. Please check all possibilities which results ; into a change of the mixture as eg.: spark-plugs, exhaust, 8 injection valve, temperature sensor, intake tract etc !
70 Lambda Probe or Knock-sensor 1 (detonation-sensor) # Lambda Probe (DME1.7.x & 3.1) ( Knock-sensor 1 (detonation-sensor) [/code]
i know i need to replace my knock sensor however does anyone have any idea where knock sensor 1 is located? also do you think this could be linked with the problems that im currently having?
