Yeah, it's getting the right person... I went to the dealership today asking them to clarify whether I needed a fuse. The manual says, single batteries and diesels= yes/ dual batteries (TP2) = No.
I have a diesel with two batteries- so which is it? The service counter person tells me NO- I have two batteries. I reiterate BUT it's a diesel. After some confusion she tells me to make an appointment to diagnose the situation(manuals are too ambiguous to be specific to my vehicle- duh and huh?).
Luckily a mechanic was listening in (and asked the right person in a hurry) and stopped me to say- look in your glove box and there is a list of codes... see if TP2 is listed, if not then you need the fuse - dual battery or not.
Guess what- I needed the fuse, as my voltmeter was telling me. All this time I have had issue after issue and it could all have been this fuse!!
