The driver's window setting has two options;

One Touch Down: A brief touch of the window switch drives the window fully down.

Auto Before Inch: Each brief touch of the window switch sends the window down in one inch increments.

Thanks for the update, What is Auto Inch Before?

My understanding is that auto is something to do with a window automatically going all the way, and inch is when it moves one inch. I had a play with it on my Rover 25 and I couldn't see any difference really.

Anyway it seems to be safe to mess with so maybe configure it and see if the window opening / closing changes behaviour.

Hi Philip,

Tested on several SCU's, all functions enable and disable without any issues.

I know the OP posted over 6 months ago but the fob pictured that he was assured is a 315MHz isn't, fobs that have 2701 on the filter are 433MHz......

The fobs pictured that use the smaller CR1220 battery are the "new" type being manufactured for Xpart as a replacement
for the 3TXA/3TXB/17TN and is supplied under part number YWX101220A.
These usually "program in" with only 2-3 presses of the button rather than the usual 8 presses.
The new design fob will only be manufactured as 433MHz, 315MHz is now discontinued and no longer available.

Another piece of info, the 3TXC fob variant was a Land Rover item. It will program to the 5AS but it does not have the components
fitted to make use of the "friendly mobilisation" feature where the immobiliser self-cancels when the ignition is turned to
position II. This fob was originally supplied with late Land Rover Freelander 1 that didn't require this feature after the introduction
of the BMW EWS immobiliser on these vehicles.

The SAIC SCU was no different to the MGR part, many SCU's used in the LE500's were obviously from unfinished production line stock as the VIN numbers in the units I have worked on 
show them as being from every model type and they stuck the SAIC VIN on a label on the outside of the case rather than change what was stored in memory.

If the alarm triggers while entering the EKA code just continue entering it, this as far as I have seen is normal. I have tried the EKA code on many SAIC SCU's and it has always worked but rarely on the first try, using a mechanical method like a door lock with all of it's pitfalls to enter a code is a lousy design.
