Who's seen this before...

...and what was the fix. Also the "reduced transmission options" message.

It happened to me off road (09 D3 with 4000km on the clock). Just climbed steep track in low range and was going down gentle slope on other side. Probably should have gone back to high range but there was one more steep hill to go. As usual single vehicle exploration trip, nearly sunset, two kids in the car and starting to rain with 10km of low range to get back to the bitumen.

The fix: turned the car off and then restarted. No problem after that.

Awaiting to here dealer verdict at service this week

I saw it when my canbus failed with multiple failed modules and a pierced wire on the passenger side firewall.

funny you should post that...I had a similar thing happen when starting the car at the Winery...not alcohol enduced..

Had most of the warning lights come on and that message. Turned the car on and off which cleared most of the warnings except the transmission warning light. This cleared itself after I turned the car back on after a wash at Werribee.

I've had this fault occur a few times now and it clears. Dealer has also replaced crankcase sensor and powertrain control module but it still happens. Not sure why...

I had this with a flat battery, I am told it happens when the voltage drop's below 11.5 volts.

Given it happened to 3 out of 6 Discovery 3s yesterday could have something to do with the conditions -- low range, several steep climbs.

I shall investigate.

Guessing that gearbox got too hot? Also, when did the D3s in question last have their transmission fluid changed?

edit: just seen that the pic shows 37000km, so fluid change shouldn't be a factor.

edit2: I remember that faulty rear e-diff software can cause this and there was a TSB for this some time back. It can also be caused by blown brake bulbs or incompatible electronic braking systems for trailers.

Fluid change shouldn't be a factor if the vehicle was correctly serviced and all three have been. No trailers attached. Not all of the three have the rear e-diff.

Faulty EPB module can give this error, but odd that three cars would all develop this symptom at the same time. I doubt it would be overheating, unless you saw the "transmission overheated" message just prior?

Have you checked the rear multi-pin connectors above the rear passenger wheel?

Cheers,

Just remembered - I got this (and a few other reported faults) due to a faulty wheel sensor (rear driver's side) a few years ago. If the speedo stops working as well, it will also be worth checking the front speed sensors.
