Amen to that...

Yes

The car isn't being driven today. Tomorrow morning could be fun. The red alarm LED is still flashing on the dash - does this mean it isn't flat yet???

so I tried the remote heater this morning as it was6 degrees.
It ran for just over 10 minutes and then shut down.
Difference it made to cabin temp?

none.
sweet fa difference.

and driving off, the radiator temp was cold, and took same time as usual to warm up - so i guess the mod has been to disable the remote heater.

What temp did you set on the remote heat ? Far to many gone...

what do you mean what temp did I set on the remote heat ?
It will heat up to 15 degrees as per the handbook. The temp is not settable.

agh ok i thought on my 11.5 that you could pick the heat required via the temp control Far to many gone...

OK - so as I have the MY11, it should heat to 15 degrees.

how does that work pls? My RR is the 11.5, and there is no mention in the handbook about changing the temp setting.
page 62 and 120 in the handbook refer to the heater. I can't see anything there that says you can use the internal temperature setting.
Anyway - my internal temp setting was 19 degrees.......so this doesn't help.
And the dial doesn't go below 16 degrees....so am I missing something?

I thought it would heat as long as the temperature was below 15 degrees outside? Not heat the cabin to 15 degrees? Have you seen info to the contrary? (I'm only going on the earlier models behaviour though)

The FBH unit will cut out if voltage falls below 11.4V. Also, a 10 minute run will never heat the cabin as the changeover valve only opens when the coolant reaches a set temperature in the engine first.

I think the temperature guage on the dash starts at 50C so you wont see the dial move unless the FBH gets a full 30 minute run. 

I changed my post as I just checked with LR and my model is actually the 11, not the 11.5.

Doesn't change my problem though that either way, it cuts out after 12-14 minutes, and heats not.

sorry to ask a dumb question.
you talk FBH...I talk webasto.
what's the difference?

The Webasto is a Fuel Burning Heater. Much like the Range Rover is a 4x4.

As per my above post - it will stop short of a full run if the battery voltage drops below 11.4V. You could test this with a multimeter across the battery terminals or jump points to see if the voltage is indeed dropping below this threshold.

Also, as I said above, the engine is heated first, this generally takes about 15/20 minutes from experience (depending on the start temperature of the block). Then in the last 10 minutes the bypass valve opens and then heats the interior.

I had an issue with my FBH before Xmas, it would fire up and not heat the cabin. It was only heating the engine block, indicating the HVAC was not initiating the changeover valve to move to the cabin setting and start the fans to circulate the warm air.

Guava traced it to a software issue on the HVAC (heating ventilation air conditioning system). Land Rover supplied updated software for the HVAC and it works fine now.

I have fixed my occasional flat battery by putting a battery conditioner on when the FFRR if laid up for a few days if I am away on business or using another vehicle. I connect it to the permanent live power socket in the boot. I have conditioners on all the Land Rovers so there is never an issue with any of them starting. 2018 Range Rover Autobiography

1959 Series II
1950, 1952, 1954. 1955, 1957 Series I
1952 Minerva Ambulance

so yesterday I put the battery onto charge with a charger / conditioner.
once battery fully charged (took about 6 hrs using a Ctek XS7000) i took off the charger.
this morning, i use the FBh....
and guess what
somehow the battery has gone flat overnight, and within 5 minutes the FBH has shut down to preserve the battery.
and this is on a car which is meant to have had "the fix".
well I am completely fed up....

Land Rover.....if you scan these threads....you have one customer in me who may not be buying LR again in the future unless this problem is rapidly recognised (the chap on the help line yesterday was in denial......) and fixed.
