According to my dealership there is a bulletin for the S60 MY01 about the cams getting dirty.
Does anybody know more details about the bulletin and/or what the symptons could be?
According to the dealership it might cause pinging. And.. I'm allergic to pinging... (seen the history of my car).
They claened the cams (they were dirty). So I gave it a try. And indeed in 2nd gear full throttle I can hear some "zzz", "zzz" at about 4000 rpm (never tried before that way). Now of course I don't know if this has anything to do with the "polluted cam problem" (it should be clean know) or if this is normal (I used RON 95).
Anybody can help me out?
Regards,
Dutch
