Heater controls

[Scotclimb]

Hi and apologies if this is on the wrong section. Rather new to this. We have a 2008 cali se. The heater/cold fan dash panel with the digital display is playing up. It’s comes on sometimes the drivers side heat button doesn’t rise in heat tge fans work and the passengers side heat rises when pressed. Is this an easy fix or a replacement panel/unit. Thanks in advance

Can you post a photo of the Dashboard Heater panel?
If you have the 3 zone Climatronic System then you can try an electronic reset. This reset video works on VW vehicles.

Hi this is our one. Great if it has a reset trick. If not do you know where I can get a replacement unit. Thanks

Unfortunately I can't find anything regarding an electronic reset for that model.
If the panel controls respond but no change in temperature it could be one of the servo flap motors has failed rather than the panel.
VW or a good independent are your best bet to get it sorted, or remove panel and check the flap servos if you are confident.
Sorry, not much help I'm afraid.

I’m not sure what the flap servos do. The digital display is failing aswell. It displays sometimes then when you use it tgere are digits missing. The cruise control doesn’t work either. Could this all be linked to an electric fault somewhere? I read in another thread the cruise control is down to a clutch/brake switch. We just got the van on Monday so fixing these issues before we go away for a couple of nights. Also tge aux heater blows out cold air only with the temp setting at 6. It sat around for a bit before we picked it up so hoping it’s a leisure battery needing a good charge?? Any tips advice greatly appreciated?? Thanks

OK, I see.
Yes , there are switches on both the clutch and brake peddles that can cause failures of Cruise Control .
The Parking Heater will fail to start if the Leisure batteries are below 11.5v or less than 25% fuel in the tank.
Check the Control Panel for any fault codes. See below.

With regards to the Heater Controls you might be lucky on eBay.

For those of you who don't know, if you ever get any problems with roof stuck or any other error say with the heater or fridge, you are able to access the hidden menu in your control panel as used by the VW Engineers.
Access as follows:

1. Hold down the centre of the rotary button together with the menu button (button below with the squares on it)
2. You will get the hidden menu.
3. Rotate the rotary button to get to "VW diagnose" and select this by pressing on the centre of the rotary button.
4. If no errors are present it will display "no errors"
5. If Errors are present then a list of errors will appear
6. Press the centre of the rotary button again to delete all the errors
7. Repeat process above just to check that errors have dissapeared!
8. Re-configure the time and date if neccesary.

Any problems should be resolved assuming these are Electronic and not Mechanical.

Great advice thanks. Just home from work. Tested tge aux heater with engine running and blasting out heat. Does this now mean leisure battery is needing a charge from hook up or replaced? Also is there two leisure batteries? I think I have one in the back bottom cupboard and one in the front? Which one works which items?? Sorry for bombarding you with this but I’m new to calis thanks

Just tried the fridge whilst engine is still on. When I select on it clicks at tge fridge but on the display it jumps back to the off straight away. Is this a fault or should the engine be off for this to work?? Thanks again

2 Leisure batteries wired in parallel so they act as 1 large battery.
There is a 50 amp cube fuse on the +tve pole of the rear battery. Prone to blow which means you end up with just 1 battery running things.
What does the Control Panel voltage say with engine Off and wait 1 hr?

Sounds as if there is a fault.

Early Californias had a problem with the Earth Shunt which is located beneath the fridge. Basically it requires a better earthing attachment. An easy repair but the fridge needs to be lifted out.
This could be the cause of the problems. Also the Leisure batteries could be well past their sell by date if original.

There are full instructions in the Forum Resources section. Unfortunately it is for VIP members only.

Thanks for your help and advice I’m hoping it’s a battery issue. There’s a 50 amp block fuse which may have blown resulting in me running off one battery instead of two. I’m trying out where it’s location is to rule that out before removing the fridge for the earth shunt route. Thanks again

Hi I’ve now found the block fuse sits under the connection How do I test if it’s broken and where would I source this?? Euro car parts Halfords or specialist suppliers?? Thanks
Battery was showing 40% on display panel.

Ignore the % . It is an iffy calculation based on periodic data of power consumption. The voltage however is accurate.

When the heater or fridge start, power consumption is high. If the voltage drops to 11.5v on starting then the fridge or heater will switch off.

I would suggest getting hold of a multimeter to check voltages and fuses etc.

I have a multimeter. But a bit of all the gear and no idea. Do I check the battery voltage before and after an appliance is used? Thanks

The Control Panel will do that. Put the batteries on charge for 24 hrs. Wait 12 hrs.
Use the multimeter to check the 50 amp fuse Is Ok by disconnecting the +tve on the rear battery but insulate this lead from the body work as it is connected to front battery and still live., and then check voltage from fuse to -tve pole. If no reading then fuse may have failed. Check voltage again but remove fuse. Take a note of reading.
Check voltage from -tve pole and the red lead you removed which is connected to front battery.
Both voltages should be the same. If not probably time to change leisure batteries.
you would be ok on hookup but not camping without.

NB. The leads are long enough to lift the rear battery out without disconnecting in place.
Open flap, undo bolt in front of battery holding battery clamp.
Use a paint scraper or similar to help lift and slide battery out of compartment.

 

[Scotclimb]

Brilliant thanks I’ll let you know how it goes. Thanks

 

[steve_b]

Theoretical you don't need to disconnect any leads to test the cube fuse, as long as you can get to both the top and bottom of the fuse, which I think you can.

basically put one lead on the multimeter on the -ve terminal and measure the voltage to the top of the cube fuse. then measure the voltage to the underneath of it / post of the battery. If they read the same then the fuse is good. if different then bad.

check them any time, since the fuse should connect the top and bottom together then they should always read the same

--edit- just seen your earlier picture. so check the voltage between the -ve and the bit of metal that you can see poking out of the top of the cube fuse, and check it against the voltage between the -ve and the terminal that you can easily get to underneath the fuse

--edit again- does the fridge work if you have it plugged into the mains hookup? Fridge cuts off if the voltage drops below 11.7v I have a recollection. In theory running the engine would provide this but hookup is also worth testing. Faulty earth shunt is a good call on other possible solutions

 

[Scotclimb]

A little update. Tge cruise control was a £20 clutch switch. Still need to fix tge heater control unit/leisure battery issues and now a buzzing noise from engine bay when I switch off the van. Any ideas on this buzzing?? Thanks

 

[steve_b]

Buzzing, or a kind of 'moo' sound? Could be the moo valve, n75 turbo boost controller that is just in the bonnet under the window . Search for n75 or moo valve may help, if it is that. Relatively cheap and easy fix - would not recommend a clone part from eBay though.

Great thanks I’ll order one up.
on another note, I have like a twanging noise from passenger side suspension when crawling and turning. I’ve read it may be a strut bearing. Would you agree?? Thanks

 

[steve_b]

I'd google your engine type and "moo valve" first just to check but it's a pretty common transporter problem. My suspension makes all sorts of growls and twangs at low speed, no idea what it is but hasn't yet proven harmful.

Hi just thought I’d ask again. The control panel buttons work on the passenger side. The driver side red button should increase tge temperature but it does nothing. S as Lao tge digital display has a mondo of its own. Most of the time it’s blank. When you push the fan it comes on but some digits are missing. Then you could be driving along. No one touching it and it displays some digits then a couple of seconds it goes off again. Could this be loose connections in tge back? Or the unit on its way out? I’ve ordered removal tools for the roadie so I can get a look at tge back of it. Any advice would be great? Thanks

Definitely worth checking for any loose connections but it could be internal problems on the circuits inside.
