Hey I need some advice! I have a 2015 Jaguar XF 3.0 Supercharged. I love this car. Ever sense I hit 90k miles she’s been having some problems. Yellow engine light on, running fine. Had read a couple times and read as cylinder bank 1 bank 2 to low at idle. running lean. then brought into dealer and they said “ I know 100% for sure that lean condition is coming from a leak at the supercharger gasket, and the PCV diaphragm is torn."

they want to look into it more, but i don’t want to get scammed at dealer. Is this an easy fix, can i ride with light on? or is there a simple way to get rid of this problem. Thanks guys!
Edit

 

First just get the diaphragm done,then see if any improvement, you can do that yourself very easy

 

Okay will do thank you
