I have a 95 318i, code says I need knock sensor #2. Its the one between cylinders 3 & 4. I dont know if its the same as the #1 sensor. If you have one that you know will work shoot me price. I would like to change it soon to see if it helps with my idle.

 

$103.83 List price, yours for $70.00. Let me know if you need it! Their are 2 per car. To be honest it maybe wise to change both as it isn't the easiest job and if the other one goes bad you'll regret it later.

 

Got one for $20 at a yard. thanks.
