Atto,
Thankyou for responding. I'm having a difficult time resolving this issue.
It sounds like a resonance coming from the exhaust. Kinda like a hum...hum...
The car also makes a peculiar noise at 120 Klm/hr and coming back through 100 Klm/hr
So far Lexus has changed the tailshaft, put two new tyres on, replaced the front rotors, and placed a resonator behind the cat. converter. The later making a slight difference.
When the problem became "unfixable" I was told it was a series "characteristic".
So if I can find one IS200 thats runs smooth, Ive something to argue with.
I hope your car is perfect - they certianly are a nice car to drive. I traded a BMW318 in on this car and I consider the Lexus a better deal. Except for this bloody noise.
Mate, where are you situated as I'm in Queensland.
Would you be willing to have your IS checked out at a Lexus dealership? At my cost.
I would appreciate your response.
