SL55 weird sound
hey we recently got a 2003 sl and when you step on it sorta quickly from below 1500 revs, the car makes a "pew" or squeak sound. i know for sure its not the tires because im not stepping on it THAT hard but i was wondering if it was like a wastegate or something because it happens once in a while on gearchanges as well if you have the top down and can hear it. any ideaS?

Angry squeak
Yep mine squeaks also. supercharger engages and squeak goes the clutch.

Had the dealer applied some lapping compound on it...went away for 1 year then came back. I hate it!!!!

i am beginning to regret I bought this car. SL55 04

WHy can't they make a car as reliable as the Lexus! Don't they get it, we have choice and next time it won't be MB.

Because last time I checked, the SC430 wasn't even considered enough of a roadster to be considered for Car and Drivers drop top shoot out.

Lexus cars are wicked nice, but totally for a different audience -- the ones who want appliances. :o Not driving machines (relative of course)
