Sorry to bump this, but I recently got my own copy of microcat land rover parts program (running in vmware fusion on my mac). I did some digging on the parts just to see what exact parts my vin has in it (the * next to the part is where my vin falls on my mid year 2013)
I don't know for sure that I have "the update" because they show I have the same parts as some of the impacted vin range, but yet my vin is after the vin range mentioned in the TSB... and the FIX parts are outside the range of my vin.
So either I have an outdated TSB, or they never had a 2013 tsb, (this was announced in 2015, so you would hope they knew about 2013 impact). I'm so confused.
The parts catalog only says the vin ranges and that a part is superseded, but not why or how the part changed. (which sucks, that would make the parts guys job easier) Hopefully this clears up part number questions as people dig into this project if they DIY or anything.
