So took my lr3 to the dealer to have it diagnosed since I still had an engine system fault, where they came back with it needing a new brake pedal switch to take care of the engine fault and as for the christmas affect with all the faults, recommended replacing the battery. Gonna let them fix the line, but I think we can handle the battery....she just said to make sure it's the same group size....did you have to replace your battery at all? Any recommendations on where to get one besides Checker?
