Hi folks, I have an issue with my LS460. I'm losing air from front right and i'm sure it's the valve. MOT recently highlighted possible issue with sensor and chap recommended fitting new batteries or sensors all round. Different chap suggested sensor replacement cost of £1,200!! Has anyone come across this issue. I think because my car is pre-2010 it won't fail the MOT on this point, thankfully. Let me know what you think. Any advice would be welcome.
