I did the same, and provided a copy of the TSIB to my dealership Service Manager. As it was the first time he'd seen it he contacted Lexus GB, but got the same answer as you, plus some BS about it being a different part number in the States and/or the pads being made by a different manufacturer (smoke and mirrors).
In the States the initial TSIB for excessive brake dust was for the IS350, but the IS250 was added to it a a later date...it's a response to the number of complaints, and in the UK/Europe we don't have sufficient numbers.
It really pi$$es me off that Lexus do not apply a TSIB globally as a matter of course, even more so considering how much we pay for the cars in comparison to out American cousins. :tsktsk:
As a matter of interest I bought the OEM ceramic pads issued under the TSIB in the States, should be fitting them in the next couple of weeks.
Hey Tango,
Could you please let me know how much you got them for? Was it delivered to the UK?
Also, you gonna fit them yourself?
