OK, so I'm hoping that someone adventurous would be willing to have a closer look at their new L494. Particularly if you DIDNT order it with Remote Park heating.

Looking through the bits and pieces, it would appear that the diesels will still come with a FBH, just a slightly different design and situated in a different location from the earlier RRS.

There seems to be one difference between the std FBH and the Remote/Timed Climate FBH.

The Remote version has a cut off solenoid to force the circulating coolant into the passenger heater matrix to warm the inside of the cabin.

Without that, it will continue to heat the engine block (not a bad thing to protect your engine and help it warm up in the morning).

The remote unit is a slightly different design and like the earlier version, should link up to the FM antenna in the roof. So I suspect that this newer version will also connect to the same aeriel that is used to retrofit the 2010-2013 models.

Here is the placement of the components.




So, I'm looking for someone that did NOT order the Remote park heating to have a look in the engine bay (remember the pic is likely to be for a LHD model)
Remove the engine cover as well as the battery cover and what would have been the Aux battery cover in old days
And take a couple of pics for me?

Then, if feeling brave, remove the interior trim off of the tailgate (they will pop off as they're held on by plastic clips)

What you're looking for, is an unused connector anywhere from the top of the hatch down to about 1/2 way down.
It would probably be covered in grey foam to protect it. But I need a picture of it if possible.

If we can distinguish that these exist (which is contrary to what dealers have been saying, but they may not be looking in the right place!) then it may be possible to get it at least partially working.
I know that I can technically enable the functionality on the RRS2 in the same way as the previous RRS. It would appear that without changing the changeover valve (which will only heat the internal heater matrix) that we may be able to get it working in the same way as the previous RRS.

Any brave souls with their new cars able to have a look for me......? Bodsys Brake Bible

Hi Bodsy

I received this reply from JLR Dec 2013 as I had called them ref the absence of the FBH.

"Dear Mr Hill

I write further to our telephone conversation on 27th November 2013. Please accept my apologies for the delay in responding, and I assure you that no discourtesy is intended.

I have taken the opportunity to liaise with our Product team and our Engineers in relation to your comments regarding the auxiliary heater function. Our Product team have confirmed that the Remote Park Heater function is now a cost option across the Range Rover Sport derivative range.

Our Engineers have explained that our new diesel vehicles have an electric auxiliary heater fitted as standard that speeds up the heating of the vehicle as they would otherwise be slow to heat up due to their inherent efficiency.

We could not package this electric heater solution on Discovery 3 and 4 so fitted the Fuel Burning auxiliary heater as standard in the UK to speed heater warm up. The electric solution is inherently more fuel efficient and lighter but it cannot facilitate timed climate. This design is one of many weight and efficiency improvement measures such as the aluminium construction designed to transform efficiency, performance and dynamics from the outgoing vehicle.

The fuel burning auxiliary heater is required as part of the timed climate option on our new vehicles. This fitment policy is in line with our facing competition.

I understand that this information may be a disappointment to you, but I hope this will not spoil your enjoyment of your vehicle.

If I can be of assistance again in the future, please do not hesitate to contact me.

Yours sincerely,

Jason Stuart

So, my understanding has always been that the FBH omitted on the RRS2 hence the £1k price, but it's not absolutely transparently clear! It would save weight as well. Maybe, one will have to do as you request!! Having said that, if it has an electric heater fitted, then it's not of much use imo as there is no apparent benefit as under frosty conditions it is a fairly lumpy idle from glow plug start for a brief while and minimal cabin heat for 5 mins. The Webasto FBH on Disco 3/4s and RRS1s much better, but then emissions and thus road tax much higher!

Thanks for that

All the topix info points to a fbh that is for timed climate and an fbh that isn't. Only difference is the solenoid to re route the water.

The electric heater seems to be in the heater matrix, different from the fbh which is still fuel powered.

Really need to have a look in the engine bay of one.

Anyone around Saturday that wouldn't mind me having a quick gander? Bodsys Brake Bible

I will be in Aldford, couple of miles south of Chester most of the day on Saturday if that helps!

I'll be in Surrey and reading Saturday, sorry, should have said
Can you have a look in your engine bay, at the back for an elusive fbh...... Bodsys Brake Bible

That would be excellent. Are you around tomorrow 5.30ish?

I'd be back to Telford around 5.30

Drop me a PM with your address if you don't mind. I may also take the opportunity to check the CCF settings if you were OK with that also (I'ts painless, dont worry )

PM sent.

Right, BIG thanks to Disco for letting me have a look around his car and take a couple of pics.

So your engine bay should look like this



Then look at the rear left hand side for the newly designed FBH tucked away behind the suspension strut.



Once you've spotted the fbh, you need to see if it has the solenoid and extra pipe work (not that clear, but hopefully you get the idea)



Then the receiver unit is behind the rear D pillar



So.... What I need Bob (or someone else who doesn't have timed/remote park heating) to check....
1) is there a FBH in your engine bay
2) if there is, is there a solenoid block with a couple of pipes or just a straight through pipe connector?
3) if feeling brave, the little airbag sign on the D pillar flicks off, Torx bolt behind it then the trim pops off with a couple of clips. Looking for a four pin connector with probably 3 wires coming out of it. Usually wrapped in a bit of foam.

So.... Over to someone else who has a diesel L494 to check

Just been out in the rain, to take some photos with the phone. But doesn't look like its fitted. Do you want to pm me yr e mail address and Ill send some photos over, but I dont have the fin arrangement on the top left...theres a gap there.
