The cover for the back-side of the left front parking sensor (in the wheel well) is missing on my MS. I have an upcoming mobile appointment with Tesla to replace a headlight, so I add this to the list. They sent a quote for parts and labor of $140 to replace the whole wheel well cover - (Correction: Wheel Arch Liner - Front - 2nd Generation - LH (Remove & Replace)). Can I just buy the cover for the radar sensor and replace it myself?
