Can You Tell Which Software Updates Are Applied and Does it Matter.

If only to ease a curious mind??

The first update helped, but made for a rough down change, the second (and still current) is great. But if you didn't have the problem, the first update would have been a backward step, especially as at the time the second update wasn't available.

Hi Matt,

As phl said, I had the update done due to the pregnant pause at round-abouts.

They also adjusted the brake light switch, and the combination of the 2, seems to have improved the issue. It is much less noticeable.

But, if you are not having any issues, then there probably isnt much point in doing it. Why risk making it worse, as Phl discovered before the issue was solved.

My Independant recently did a software update fir the transmission and I do feel it is smoother and a little less laggy. The difference is not dramatic but it is noticeable

So you don't need a LR dealer for software updates? I thought that they would guard them like gold so that they have a captive market. Very interesting.

I don't know if it is a genuine Land Rover software package or a third party one. He has the Autologic system.

Based on this information from the Autologic site it look like they do get Land Rover updates although you could also read it that they replicate the Land Rover updates.

Flash programming – Many control units are flash programmable.
As part of the on-going support, vehicle manufacturers periodically release updated software, often to overcome running issues. Autologic enables you to do these updates. Autologic can program the control units on Land Rover vehicles from 1998 model year onwards. Software files are constantly updated to keep up with fixes from Land Rover. Most powertrain and body control units need programming before they will work on a vehicle. Autologic can also program keys and alarm remotes for all Land Rover models.

BBS provide LR modules from their web-site - even D4 ones for which no-one other than LR (AFAIK) has a device to install them via the OBD port. I have a copy of the particular version of the ecm s/w that's currently installed on my 3.0 D4, not that I can load it.
