that's where mine was too. It was on the right side of the passenger's side footwell and mounted vertically. The range rover diagnostic computer was all taped together and kinda crammed up in there behind it. At the time I didn't think that there was any way that it was factory in that location, but I think I was wrong. (By the way, it's a retarded place to put it if you ask me.)
I'd suggest moving it, B. Put it in your cubby box, or if you relocate it to your under seat storage area, make sure that you mount it well up off of the bottom. I know several guys who have thiers relocated there, but have them mounted on top of blocks of wood or something to keep them off of the bottom of that storage area. Use a ton of grease and put it in tupperware too.
I never relocated mine and as a result I went through a few ECU's while I had my truck. I ruined the first ECU by going through a car wash when the truck was new and I actually tried keeping it clean. One was ruined from rain water that leaked in by the door and run into the ECU. ( Oh yeah, after I ruined the 1st one, Land Rover installed a new one and put it in a plastic bag and remounted it to the footwell. The plastic bag was a genuine part. I swear to God. The bag was labeled and everything. It was a stupid "fix" for a stupid design flaw that should never have been in the first place. Oh, and did I mention, it didn't keep water out?) The last one was flooded with Dave Souza in the Green Swamp in Central Florida (remember that Dave? We buried the truck so bad that water actually came in OVER the passenger side door and swamped it.)
Relocate it. Even if you're not expecting to do deep water stuff like we have to do down here, it's still not a very smart place to put it, especially in a soft top. Either that or just get another Tdi...that's what i did. ;-)
