No heat Level setting available for heater

[Hedley Wright]

First time using the heater in my 2022 6.1 Ocean and I’m stumped. When I go to select a heating level the up/down arrows are there but no number. Am I missing something obvious? I’ve tried pressing the arrows and also turning the knob but nothing.

 

[GrumpyGranddad]

Have you checked the Operating Mode? Just wondering if its set to ‘Ventilate’ ?

 

[Perfectos]

Can you set the Level in “settings” ?

 

[Hedley Wright]

Thank you but no, it’s set to heat. Interestingly it is actually kicking some heat out, I just can’t set the temperature.

 

[Perfectos]

I note it’s the first time you have used the heater.

is your fuel tank more than 1/4 full ?

Can you leave the heater running for a while, (30 minutes+)
I once had on issue with my diesel heater after the van fuel system was worked on, it turned out to be air in the fuel line to the heater, the control panel would cut out as the heater tried to go through its initial glow plug heat phase, due to the lack of constant supply of diesel (inbuilt protection of the system). once all the air had cleared from the system, it worked correctly.

the fact that you are getting some heat means that it should work, possibly the issues is with a software protection to prevent dry running of the heater.

It may not be this issue but it’s another thing to try before visiting a dealer.

edit: does the heat immediately button work ?

try putting the van on hook up , then try the heater ? Possibility the leisure bats are low ?

I’m on hook up which rules out the leisure battery factor, although they’ve plenty of charge. Diesel tank half full, so no issues there. I’ve had it running for an hour, giving out heat as and when the thermostat switches on. Heat immediately works, but as that uses the last used temperature setting I’ve no idea at what level.

Has anyone ever had this missing temperature level setting in in the display problem?

Maybe a system reboot might be worth a try @Hedley Wright ? I.e. Pull and replace fuses 5 to 8

Or disconnect the starter bat for 15 minutes (you will get a load of warning lights come up afterwards, but a short drive will reset all warning lights )

Have a look at this there is a couple of videos one shows how the display should look and the various layouts and lights that should show up, if nothing else it should show you how the system should work (post #26)

Auxiliary Heating - T6.1

Hi Stuart, sometimes it works and sometimes it doesn’t! If I can’t get heat continuously or heat immediately to work then the key fob usually does but only for under two hours and if I use it in the evening and again in the morning and don’t drive anywhere it won’t work the next evening. What...

Thanks - I’d already watched that one again to make sure I wasn’t missing something. Great explanatory video.

Thank you. I might try that when I return home from my week away, don’t think I’ll risk screwing something else up while I’m away as I’m not mechanically gifted.

Are you in the uk (Away) ATM ?

if so call VW assist and get them to sort it out, that’s why you have VW assist, you may as well use it, if they can’t fix it they will at least confirm what the issue is

Good thinking, I’ll give them a call in the morning.

Let’s us know how you get on,

remember to take a photo of the VW /AA patrol showing the fault codes on their lap top / tablet so you have a record and can share with others here

Will do. As I’m getting heat out of it (no idea at what level it is running) I’m inclined to wait until I get home and can use the Carista to reset to defaults - just in case of warranty issues?

Vw assist / AA work on behalf of VW anything they do is as if VW did it, if nothing else you’ll have a good idea if it’s a simple fix or if it’s a dealer visit to sort out.
VW assist will not even look at your setting if you have changed them in carista

if VW assist can fix it at site they will

For information - I called VW Assist but they declined to help as the heater isn’t something that affects the mobility of the vehicle. Told me to contact my service centre. It’ll wait until I get home.

The plot thickens. I just attempted to turn on the heater for the night (it has been working, albeit at an unknown level but I suspect level 1) and all of a sudden I get numbers between the arrows. Yay.

Unfortunately, although I can now choose my level for continuous heating the system thinks about it for a bit then quits, no heating icon. I’ve been through the fault finding checklist that VW Customer Care sent me (nothing new there) but it looks as if I’m in for a chilly night.

What is the Control Panel voltage? Have you more than a 1/4 tank of diesel?

Thanks but I’ve checked all those back in the thread.

Latest update is that I gave Heat Immediately a try. It accepted the input, heater light came on yellow but nothing happened. Tried to cancel but the control unit got stuck in a “please wait” state. Cycled the ignition to see if that would clear the loop and it did, heat immediately is now on and I’m warming up! I’ll see if it stops on 60 minutes and then, hopefully, set heat continuously for the night.

It would be nice to think that it is now sorted and will be ok going forward. Thank you everyone who has chipped in trying to help me out. You’ve been more helpful than VW Assist (“sorry sir but unless you can’t drive it or are in danger we can’t help”) or VW Customer Care who just sent me template email replies without ever referring directly to my missing numbers issue.

Just so you’re aware, the Heat Immediately unfortunately has a max run time of 120 minutes ( I think that’s explained in the following video from California Time ). To reset the max run time, you’ll need to run the engine for a while.

For Heat Immediately - look at the video at about 10 minutes in. Your initial issue of no heat level selectable is not covered, nor have I seen this myself. So that’s a bit of a mystery.

 

[Perfectos]

Try the heater in normal mode once the heat immediately has been on for half an hour or so, it may be that the problem was / is fuel related and has now sorted itself,
I know when I had my issue, it took quite a few goes for the heater to fire up properly (end the glow plug phase, which heats the ignition chamber to operating temp, then the glow plug goes out and the fuel self ignites)
mine kept cutting out and not wanting to run more than a minute or so, then it fired up and has been fine ever since (air in the fuel line was the issue, which prevented the glow plug phase from igniting properly.

To be fair, it’s the AA that respond, and while they’re good generalists, they know little or nothing about Californias from my experience. The typical fix would be to disconnect the starter battery and connect it after 2 minutes.

This will be of zero help at the moment, but when in cold weather and on electric hook up, we use a small electric heater, controlled by a thermostat. The diesel heater is good once it’s going, but we’ve found a bit tricky to get it right. The Kampa Diddy heater, along with separate stat, is reliable and good enough down sub zero outside. Fits in the drawer ok. And you don’t burn diesel., plus quieter for other campers.
