Squeaky noise from engine bay 335i e90 n55

[alrichperreira]

Hi guys so my squeaky noise has returned
3 months ago I replaced my Vbelt with tensioner but didn't replace any pulleys as they were Stil fine at the time, suspecting pulleys are gone should I replace them all? Another thing the squeaky noise starts once car is warm after a lekker drive on coldstart its quite no noise until it warms up it starts to squeal

I think it's due to the good looks of your car...

Looks good. Sorry I have no advice.

You can identify the noisy one like this.
Once she starts squeaking, spray a little q20 on each pulley, then you can change the one that goes quiet ...

Hmmm could be the tappet cover, I had a squeaky noise when I had a E82 135i N55 and had to replace my tappet cover

Ok cool thanks Nick so I poured some water over belt and noise went away it wil most probably come back ones water dry up will just replace all pulleys

@the mo

I have the same issue that comes and goes every month or so on my 320D also replaced the v belt. I was told it's the belt tensioner by my mac
