Thread: Dash Display not showing gear selected

Is it a recent behavior or has this always happened?

The BCU controls most of the instrument displays. Have a look at the transmission type setting in the BCU and make sure is set to automatic. If its set to manual the gear selected doesn't display. Id guess it will disable the m&s lights as well.

It might well be something else but worth checking this first.

Agree, press the "sport" button and see if the lights work. Are the lights around the gear selector (green background lights and red indication lights). If not lift the surround and check the plug underneath. Also check the plug on the xyz switch on the LH side of the gearbox.

Only had the vehicle a couple of weeks. Display worked until today. Checked the WXYZ plug on the side of the transmission, unplugged, cleaned with electrical contact cleaner and replugged. Checked with Nanocom and WXYZ selector shows correct outputs.
Red indicator lights on the selector work ok.
Green background lights are working.

All fixed. Checked BCU with Nanocom and it showed the vehicle was manual petrol. Changed to Diesel Auto. Restarted and all is good. Thank you for the info.

Think I found the original cause of the fault.
Positive battery terminal was loose. I think this may have caused a corruption in the BCU. Checking faults also showed a throttle position error? Reset this and all is well again.

Low battery voltage, or perceived (by way of loose terminal) often shows up as M&S lights flashing. While you may not have had this symptom it may be related. But to change a setting like that is a pretty specific thing to do either manually or by way or corruption.

But it could be the start of revenge for the war being Bosch vs Land Rover. But on that basis Lucas would have had to be owned by the Reich.

I had a similar occurance twice in 12 months, if a dont lock the D2 with the remote as I park it in a locked garage and leave it unlocked.
Even unlocked the immobiliser will arm and the red dash light will blink after 30 secs or so.

When I open the door and insert key and turn the engine will start but I get the m&s lights and D flashing sometimes, to clear the fault lock the car with remote and restart all is ok again.

It's like the immoboliser system and ecu does wake up the bcu?


Thanks

I'm surprised that the BCU memory wiped due to a loose terminal. The settings are retained even when the unit is removed from the vehicle. So they should be retained even with dodgy power supply.

The OP had no m&s or gear indicator showing at all. The normal solutions for flashing m&s arent really applicable, it's a different issue altogether.

This sounds more like a key issue. If I use the spare key (a cut key and fob just for the buttons) and don't start it immediately then the immobiliser will reset and I need to either swipe the fob up near the ring around the barrel or press the unlock button again. This adjusts the flash pattern of the LED and it will start. If it's not reset then it'll turn over but not start.
