Our FBH will operate at 7 on our 2007 👍

From the workshop manual:

Quote:

heating occurs if the ambient temperature is less than 16 °C (61 °F); parked ventilation occurs if the ambient temperature is 16 °C (61 °F) or more.

Quote:

If the ambient temperature is less than 5 °C (41 °F), the GEM activates the door mirror heaters for 3 minutes.

Interesting.

I’m just about Rover pull fuse 13e in the engine bay which is the FBH according to a search. Is the fuse box inside the big box on the left? 2010 MY Vogue SE TDV8 3.6 Stornoway Grey- fully loaded

Yep, offside, left from the front.

Also as per TJH the FBH on mine runs below 16C. Cheers

Pulled fuse 13 from the engine bay and it made no difference.

I then connected my jump leads to my mini to provide a solid 12v and the manual heat stayed on. However it’s only blowing cold in the car.

Still scratching my head with it... 2010 MY Vogue SE TDV8 3.6 Stornoway Grey- fully loaded

Did the FBH outlet pipes get warm?

That’s exactly what mine did when the pump had failed, no hot water get’s to the heater matrix so it just blows cold.

You can rule out the FBH usually by starting the engine, and going under and checking the FBH is running by checking the exhaust, if the FBH is good it will run when the engine is started as your main coolant pump will provide circulation.

As a slight aside, but may help, do you have a towbar fitted? If so you can get power to enable unlocking as well as charge the car.

Beginning to sound as if the unit is fault as TJH says. Cheers

I could hear it running the other night when we jumpstarted it. It ran with the engine and I could hear ticking from the rear offside. Hasn’t done it since though.

So if I get underneath it with engine running, there should be something emitting from the FBH exhaust? 2010 MY Vogue SE TDV8 3.6 Stornoway Grey- fully loaded

If the FBH is running properly you should feel hot exhaust gas aand/or a hot FBH exhaust pipe. If it's cold then the FBH is not firing. I don't know if the pump for the unit continues to run if the FBH is not firing up.

Anything on the towbar? Cheers

Cracking, I've got the same Aldi one and it's fine like that. Cheers

Just been searching on this problem and tripped over your posts about the GAP being replaced and then cable faults etc..

Not good for you.

However, also found this about the FBH and wondered if it may help, if you haven't found it already.

I think jonnyboy54321 is still on here so may be able/happy to help. Definitley worth a read if you need further investigations and it proves not to be the usual sort of low voltage/supply problems. Settle down with an ale, it's a long read.

It does seem to lead on from TJH about pumps Cheers

Thanks Richard. I did see that thread doing a search for FBH problems but didn’t read it thoroughly.

To be honest this is just another issue with a car that has become a disappointment since buying. Coupled with the constant restricted performance message through the summer (although to be fair, it hasn’t “bonged” in over two weeks for some reason).

I may just fit the AGM battery being as I’ve bought it now. I could potentially sell the existing battery on as it’s been given a clean bill of health by both RAC and Halfrauds so that will offset the cost a little. If someone isn’t dependant on FBH it’s a good battery. 2010 MY Vogue SE TDV8 3.6 Stornoway Grey- fully loaded

I think putting the new battery on might be good, but if you can get a multimeter on it to monitor the voltages whilst running and stopped then all the better. Just leave the leads accessible so you don't have to open the bonnet and wake up the car. From your first post, I do still wonder if the alternator output is a little low. I'd think it unlikely that your model would be that different from mine, which runs at 14.5V whilst driven. Perhaps someone else on here could verify that.

Sorry to hear you have had lots of problems with this one. Let us know how the new battery goes. Cheers

When the RAC checked it, it was fluctuating between 14.1 and 14.2 when running so I think it’s ok. It has had an alternator fitted prior to be buying it as well so it ‘should’ be ok.

Im going to take the battery to a specialist this week and get a drop test done on it. I suspect it may have a dodgy cell as it dropped to 7 volts with IID left plugged in. Once a wet battery has gone flat they are never 100% again. AGM always recover. 2010 MY Vogue SE TDV8 3.6 Stornoway Grey- fully loaded

Sounds fair then. Trust the new battery solves the problem and that it is a faulty cell on the old one.  Cheers
