Hey Scotty I love your show on YouTube I watch them all My 2017 Buick Regal GS 2.0 Turbo (LTG Motor) 28K The Buick dealer always show me a old dirty bottom part of throttle body laying around service rep desk they always want to charge me $140 to clean it?. Is it necessary to do that service and how often do i have to do it. Thanks for adding me Clint.B Miami
Only really needs to be done like every 75k miles. Usually the carbon buildup is in places that don't make contact so it operates normally. Although It is the turbo model and they are prone to excessive wear around 140k miles and sometimes the turbo will have to be replaced...
Way too early in the vehicle life to need a throttle body service. Just more snake oil from the GM dealer, no surprise there. I would pass without question.
