Bulletin just posted - ecu noise replacement - nice work members!!!!

JB1 · 11-04-2009, 10:22 PM

So did anybody else hear about this TSB? I have the exact same high pitched noise problem, but last time I visited my dealer, they didn't know about any TSB yet. The tech did hear and confirm the noise though. It is starting to drive me nuts. It's exactly as described before, turn my head to the left and I hear it.

Solution: add CBE to your HFCs. Louder exhaust = less high pitched noise noticed.

But then there's the "hissing" problem - if it's not one thing it's another...

True, I hear it less now that I have the HFC's, but it's still there. And I think that HFC+CBE= too loud for me...

True as well, but at least the hiss is not constantly there.

I didnt hear the noise at first when i bought my car but now the noise is very noticeable. it is starting to become unbareable. if i drive without the radio on i can still hear it. I'm going to the dealership today to check out a lot of things and ill tell you guys what they say about the problem.

I take it we are still waiting for the bulletin to be verified? What happened to the OP?
