Our friend David’s 2016 Discovery 4 SDV6 (yes, that one – you’ve seen it before) is back on the lift for an upgrade that Land Rover just forgot to do at the factory: installing the elusive diverter valve for the FBH – that’s the Fuel Burning Heater, in case you’re new here.
Now, most Disco 4s don’t have this valve, which means the FBH warms up the engine nicely… but the cabin stays colder than your ex’s heart. With the valve installed, though? You get toasty air much faster, and your windshield defrosts before your morning coffee even cools down.
But of course – because it’s an LR Time video – the install didn’t go entirely according to plan. Let’s just say the valve had “opinions” about how it wanted to be fitted, so we had to improvise a little.
Also in this episode:
The rear hatch winch cable finally gave up – so we fixed that, too.
We replaced the coolant fluid.
And we did a handful of those small, invisible jobs no one notices… until they’re broken. You know the type.
All in all, this was a typical LR Time mix of fixing, failing, figuring it out, and learning along the way. If you’ve got a Discovery 4 (or just enjoy watching others wrestle with one), you’ll love this.
Join us (Vera & Christian) for another wrenching adventure, some laughs, and practical tips for keeping your Landy warm and happy.

Thanks for breaking this down! I’ve been trying to figure out what was causing the weird startup smoke on cold mornings—turns out it was the FBH diverter valve all along. Super helpful!
OMG, those ratcheting hose cutters are harsh on the ears.
I would love to see you both work on a D1. I don't buy anything newer than model year 2000 due to the amount of computers added to the D2. I was under the impression the orange coolant was bad for the aluminum engines. Have you heard of this? Love and respect the knowledge you have to share – Im just an analog guy in the digital world.
Happy Easter ✝️
Hey so is rothenberger classed as cheap tools in Germany?
Sad these mods and function can't be done for a D3.
Happy Easter
I replaced my diverter valve a few weeks ago after driving across Europe at -3, it was pretty cold inside
Great video Vera & Christian, enjoyed watching. Lots of information. 👍🏼👍🏼
Poor Vera, having to sit in the back of her own car. 😉
In our house I’d have been sitting in the back (even though the payments for my wife’s VW ID3 are coming out of my bank account 😆
And driving shifter in L405 for example needs a bit of welding on a couple of resistors to operate normally – common problem for L405. There is a chance the same applies to LR4.
I strongly recommend to do the procedure on the Queen before selling her
I removed diverter from L405. It wasn’t heating the engine until minus 20+, which made starting 4.4 diesel a soul crushing experience every time. Now even in -10 it starts smoothly.
Really, why bother about cabin temperature, when unexperienced owners enter worm cabin and think that engine is worm as well. Engine wear will result in an expensive experience
What lubricant do you use, for the latches & hinges?
I think you would do a roaring trade in marketing 'oh my god' buttons (must have Veras voice though – no imitations). I would buy one, as would I suspect many diy front yard mechanics. Perfect for when the 10 mill goes down an intake port.
"you need some sort of a minimum IQ" is classic Christian along with the explanation of German cheap vs Chinese cheap. Never change what you do and how you do it! Oh, and Vera will never be replaced by a button. She keeps Christian honest and on his toes…Happy Easter to you both!
Happy Easter, Vera & Christian.
I liked the tone of Vera's voice when she said, 'oh my god' when Christian broke smoking on the centre console.
Vera knows the he will get in trouble.🤣
😹👍
