So, we finally got an appointment with LR for the extended warranty replacement of this sensor. The LR shop manual calls for removing the exhaust pipe from header to crossmember. Looks to me like it is accessible by removing the plastic splash shield. Do they really remove the exhaust? I do realize I have little or nothing to say about how the dealer tech does this. Guess we’ll find out. The only time our baby was in the shop they cracked the battery compartment cover.
