Squealing after replacing belt and pulleys. N55
I had a squealing belt so I ordered the kit from fcp euro that came with a belt tensioner pulley, idler pulleys, and belt I installed everything my self however when I started the car the squealing did not go away. It fades after the car is running idle for a few minutes but returns if I rev the motor past 2k rpms and actually gets a bit louder as the revs increase. Any thoughts on what it could be?

Nope it was actually in decent shape I was banking on it being the tensioner because thats what I read was really common in causing the noise. Would the belt being new cause the noise? Or is that not a thing?

Never had the squealing on my N55. I did the the same job you did and didn't have it afterwards either. I did mine due to mileage and time as a preventative measure.
From what I remember seeing various threads on this topic, you may want to check the other accessory pulleys as mentioned above. I seem to recall one member saying they found the power steering pulley to be loose and had to re-tighten the bolts. |

Spray a bit of silicone spray on the belt while it is running. If the noise immediately goes away, it is the belt. Get a belt from the dealer, softer rubber and won't squeal.

I've tried the silicone spray already I don't think the belt is the issue I believe its the alternator pulley, did you watch the video I posted?

Alright boys I figured out where the squealing was coming from and it turned out to be a faulty drive belt idler pulley I'm guessing it was due to not tighten the pulley to the proper torque which is 29lbs.
