My 53 plate HSE comes up with the message on the dash on startup saying "pre heating". but i thought it was the heater plugs warming up Am i wrong  Current Stable:

preheating means the glowplugs, you get this message with ignition on for a few seconds or more depending on the ambient temperature, but once the engine is running, this message goes away; one should wait ontil it disapears before cranking the engine!
Your FBH continious to go until the cooling water has reached a certain temperature. RR 2012MY TDV8 AB ipanema sand

I have a 54 pre touch screen and my display is very similar to yours. The only difference is I have 2 boxes at the bottom of my screen (2nd pic). One with "Aux Heating" and the 2nd "Aux Ventilation".

By the looks you dont have the heating

I'm inclined to agree given that the glowplugs operate even in summer on start up and the "Preheating " message does not display then.
I don't have the "Aux heating" on my obd display but on start up at about 6C I get the "Preheating" message and the FBH comes on itself without any input from
me.
I've checked its on by checking the flue outlet.

Easiest way to see if you have a FBH is to check the exhaust which is located to the rear of the passenger wheel arch, circled in red on the photo below:

So I guess it's a given that all TD6's have the FBH. Is it a coding thing or other equipment to get the Aux Heating..?

Like the images above, I only get Aux Ventilation come up on screen so not sure if I have to get anything installed (hardware wise) to use this feature.

Any ideas..? Ash

A friends X5 had the same display as yours but the
bMW version. He got a cable off the net to enable it as no one could activate it even the dealers. There must be a way to make it appear on your screen as all TD6s have them. [img]http://www.fuelly.com/driver/rob2529/range-rover[img/]

My one has a FBH but no Aux Heating or Aux Ventilation on the [touch] screen. The FBH does fire up at 6deg but i have yet to see any 'Preheating' message.

Hmmm I was wondering if it was an HSE thing but as comports seems to have the same setup as me in a Vogue. Found a very similar thread to this one on a BMW 5 series (E39) site with folks who supposedly have an FBH but didn't know it was there. Back in 2005 the kit from BMW was £289 for the wiring and remote and receiver.

So did RR fit the thing but not wire it up? It's nice and cold outside at the moment so I'll go and give it another go.


Brrr.. no, I just get cold air blowing .

My "pre-heating" message comes on after the engine has started, so by that time, the glowplugs would have done their job.[/quote]

If you get that message with engine running something is wrong!
Preheating means glowplugs.

Beside noise produced by the FBH, you can check if it's working if you hear a knocking sound at the back: that is the fuelpump for the FBH. RR 2012MY TDV8 AB ipanema sand

No, really? Is this discussion still going?

I'm pretty sure there has been a similar thread every autumn/early winter on this board. There is so much info on FBHs here it's silly. Dan has grown mild - he'd normally be telling everyone to search. And he'd be right.

It has all already been said, but I will re-iterate: all TD6 Range Rovers came with a FBH. This was primarily to augment the cabin heater as the diesel is so efficient it doesn't produce enough waste heat to properly heat the large RR at colder temps (I think I've written exactly these words at leas 2-3 times already ). And, as an option, you could order a pre-heat (park heat) function which is activated either by remote or by the menu in the nav (or even mfd radio).

The ambient temp plays a large role in the function of the FBH as an additional heater: the FBH only comes on under 5°C.

I too have read that all you need to do is put either 12v or ground (forgotten which) to the remote control ecu plug (white/green(?) wire) which every TD6 and all BMW diesels came outfitted with to make the park heat work. It does not work this easily tho. Trust me. I know. I've gone through this. Digging a little further (on the BMW forums as well) shows that the CCF (car configuration file) must be edited to allow a park-heat function. This can be done with various systems - amongst others Colin's products (BBS) and, in the not too distant future the IIDTool.

I think that the rumors of Fbh/no FBH, enabling park heat with just a simple 12v switch, adding remotes etc. start in threads such as this one (ducks and runs out of room quickly)

Parked Ventilation
Parked ventilation is only incorporated on vehicles with a FBH system which include the parked heating function.
When the ignition switch is in position I, parked ventilation can be selected on and off using the MID or MFD. When
the ignition is off, parked ventilation can be set to come on at a programmed time. The programmed time is a start
time for parked ventilation to begin within the next 24 hours and is entered into the instrument pack using the MID/
MFD.
AIR CONDITIONING
DESCRIPTION AND OPERATION 82-47
Once parked ventilation is on, if it is not selected off it will automatically time-out after 30 minutes. Parked ventilation
is automatically cancelled when the ignition is switched on.
At a programmed parked ventilation start time, or when parked ventilation is selected on using the MID/MFD, the
instrument pack outputs parked ventilation requests to:
l The MID/MFD on the I bus
l The ATC ECU on the K bus.
On receipt of the messages:
l A red LED on the MID/MFD panel flashes at 2 Hz to indicate that parked ventilation is active
l The ATC ECU operates the blower at speed 1, opens the face level distribution flaps in the heater assembly and
closes the windscreen and footwell flaps.
The ATC ECU disables parked ventilation if battery voltage is less than 11.4 V.
FBH System
The FBH system operates in two modes:
l Parked heating, to heat the passenger compartment while the vehicle is parked with the engine off
l Additional heating, to boost heater performance while the engine is running
The ATC ECU disables FBH operation if battery voltage is too low.
l When the engine is off the low voltage limit is 11.4 V for more than 10 seconds; the system is re-enabled if battery
voltage increases to 12.2 V
l When the engine is running the low voltage limit varies, with ambient temperature, between 11.1 V at –25 °C and
below and 11.7 V at 15 °C and above; if battery voltage is below the limit for 2 minutes the system is disabled for
the remainder of the ignition cycle.
During FBH operation, with or without the engine running, the coolant valves remain de-energised and heater matrix
temperature is directly related to the temperature of the coolant coming from the FBH unit.
Parked Heating
When the ignition switch is in position I, parked heating can be selected on and off using the MID or MFD. When the
ignition is off, parked heating can be set to come on at a programmed time or selected on and off using the remote
handset. The programmed time is a start time for parked heating to begin within the next 24 hours and is entered into
the instrument pack using the MID/MFD.
Once parked heating is on, if it is not selected off it will automatically time-out after 30 minutes. If the engine is started
while parked heating is on:
l If the engine coolant temperature is equal to or more than the heater coolant temperature, parked heating is
switched off
l If the engine coolant temperature is less than the heater coolant temperature, parked heating remains on until
the engine coolant temperature reaches the heater coolant temperature.
Programmed and MID/MFD Selected Parked Heating
At a programmed parked heating start time, or when parked heating is selected on using the MID/MFD, the instrument
pack outputs:
l A FBH request to the MID/MFD on the I bus
l A FBH request to the ATC ECU and the Body Control Unit (BCU) on the K bus
l Ambient and engine temperatures to the ATC ECU and BCU on the K bus.

On receipt of the messages:
l A red LED on the MID/MFD panel flashes at 2 Hz to indicate that parked heating is active.
l If the ambient temperature is less than 5 °C (41 °F), the BCU activates the door mirror heaters for 3 minutes
l The ATC ECU:
l Energises the changeover valve
l Sends a K bus message to activate the FBH
l Operates the blower at speed 1
l Opens the windscreen distribution flaps in the heater assembly and closes the face and footwell flaps.

When parked heating is selected off using the MID/MFD, or after 30 minutes has elapsed, the instrument pack sends
FBH off messages on the I and K buses to cancel parked heating. On receipt of the messages:
l The MID/MFD switches off the LED
l The ATC ECU:
l Sends a K bus message to de-activate the FBH
l Switches off the blower
l Returns the distribution flaps to the previous settings
l After 3 minutes, de-energises the changeover valve.

Remotely Selected Parked Heating
When parked heating is selected on with the remote handset, the request is received by the FBH receiver via the TV
antenna and TV receiver. The FBH receiver relays the request as a hardwired signal to the FBH ECU. On receipt of
the request, the FBH ECU sends a FBH on request to the ATC ECU on the K bus. Provided there are no system faults,
the ATC ECU then:
l Returns a FBH on request to the FBH ECU, which starts FBH operation
l Energises the changeover valve
l Operates the blower at low speed
l Opens the windscreen distribution flaps in the heater assembly and closes the face and footwell flaps
l Transmits the FBH status on the K bus to the instrument pack.
When the instrument pack receives the FBH status message, it outputs:
l A FBH request to the MID/MFD on the I bus to operate the flashing LED on the MID/MFD panel
l Ambient and engine temperatures to the ATC ECU and BCU on the K bus
l A FBH request to the BCU on the K bus. If the ambient temperature is less than 5 °C (41 °F), the BCU activates
the door mirror heaters for 3 minutes.
Additional Heating
On Td6 models, additional heating reduces the heater warm-up time and is also used to maintain heater performance
throughout the drive cycle. On V8 models, additional heating is only used to reduce the heater warm-up time at the
beginning of the drive cycle, and only occurs if parked heating is already active when the engine starts.
The ATC ECU activates the additional heating mode when the engine is running and the following conditions coexist:
l The ambient temperature is less than 5 °C (41 °F)
l The engine coolant temperature is less than 75 °C (167 °F)
l The heater coolant temperature is less than 75 °C (167 °F)
l The reference temperature is 100%
l The blower is on.
To activate the additional heating mode, the ATC ECU energises the auxiliary coolant pump and sends K bus
messages to the FBH unit to start/continue operation (the changeover valve remains de-energised).
The ATC ECU stops the FBH and de-energises the auxiliary coolant pump when any of the following occur:
l The engine stops
l The ambient temperature increases to more than 15 °C (59 °F)
l The engine coolant temperature increases to more than 75 °C (167 °F)
l The heater coolant temperature increases to more than 75 °C (167 °F)
l The reference temperature decreases to less than 90%
l The blower is selected off.
