From my understanding only diesels of this generation have aux heaters which can be repurposed to parking heaters. But someone please correct me if i am wrong.

 

There are also Volvo petrol vehicles that have the auxiliary/parking heater..
If your S80 is equipped with it?
See on the right hand side behind the front wheel, there should be a small exhaust pipe visible… and check your dash , when turning the rotary on the left side steering switch, timers or direct start will pop up in the display.
Can be retrofitted, need a lot of parts, or remove from a car at the breakers and additional software . When not present in your car,remove paravan/plastic under wiperarm rh side, see if there is a free big connector present, if not, needs all the wiring to be mounted yourself. A lot of work, if the connector is there, lucky, only need ton install all the parts: fuellines,fuelpump,heater,coolant hoses,exhaust pipe etc….
Also it it possible to plug in a remote control, uses the same connector as the heater unit.

Hi, I have webasto from factory, 3.2 and I want to add 4G relay to be able to start webasto anytime. Can you share which cables/pins are used to start/stop webasto? If remote is steering, then only remote cables if you have diagram or any info which cables are responsible for which signal.

I saw that 1 guy connected relay output to start/stop button of the timer and it works without any other modification

if you have part number it will also be helpful, my friend has Vida, so I will try to get more info

 

Thanks for the replies!
Sadly, there is no timer when I'm turning rotary on the left side. Ignition off, 1st position, it does not matter.
Afternoon, I'll check underwheel for exhaust pipe.
I have no puller, so removing wipers gonna be pain, but still, there is no succes without trying.

 

Some petrol engines do have parking heaters, yes (as does mine) but they are programmed as parking heaters from start and not auxiliary heaters. The reason being petrol engines don't need auxiliary heaters.

 

Vehicles with parking heaters also have a webasto sticker on the underside of the bonnet to indicate this. easiest way to check.

 

I have vida, but can't find nothing like auxillary heater or else (still beginner).

In Diagnostics tab you should see the CPM module (Combustion Preheater Module) in the car. It is white (not green) and not accessible if heater is not installed.

 

Seems like a bad news for me.

But I rather check it anyway, It's 5 minute job, so not a big deal

 

I see, no exhaust here.
But i see pretty big oil leak.

Where exactly should I look for connector? Can’t see nothing

 

The connector isn’t there I see… lots of work retrofitting the heater… good luck…

 

I did some research, and price of heater is crazy, not even mentioning lots of work that i have to pay.

for now, I’ll stick with my old friend ice scraper

I have some CCM/CEM DTCs, but i should start a new topic with them i guess.
thanks for help!

 

Volvo uses a device from Webasto for remote start of the heater, Telestart T91(R), but for mobile start you need another Webasto device, Thermocall TC4 but it's 3G. There is no 4G solution readily available.

 

I have the T91 remote, an aem unit with SIM card slot (call the heater to start-stop) and the VDD dongle wich allows remote start/stop the auxiliary heater from all over the world….
