Hello, I have a genesis coupe 2012 2.0t. I recently got a check engine light and went a ran the code. Got the turbo/supercharger bypass valve mechanical p2261. I went the the dealership and they say I need a new clutch switch as well as a new rcv valve. They gave me a ridiculous quote for the clutch switch and told me to replace the rcv valve they have to completely take the turbo off. I don’t have beat knowledge on these cars and I have no idea what a rcv valve is or what something like that would cost. Are they just bs me or does this sound right? Btw I have an aftermarket ecu. Other than that everything is stock.
