Robert · 27 Feb 2020

All required components are already purchased, tested and ready for the installation.

Well invested €58=£49 :thumbsup:

My ODIS-E is also ready to upload new(better) firmware

To complete your now almost Nordic setup - an OEM control panel/timer working in parallel with remote.

18-aux_heat_webasto_overhead_control-jpg.20991

Added functionality:

timer (3 programmable times - time + week day -> max week ahead), however they are just one shot - can only activate the next event (can't activate repeats e.g. automatically every Mo-Fr at 6:15, need always to "authorize" the next one).
set mode: heat or ventilation only
set heat/vent time on remote (as in pic 30 mins)
child lock

And finally the link to the parking heater firmware file

FL_7E0963272B__0009.frf - Parking Heater

Robert · 2 Apr 2020

Once the Telestart is triggered remotely it produces 12V DC output on pin number 3 (green wire in my case).
This then could be used as a ON confirmation signal. I don't know where to connect it, maybe horn

Robert · 6 Apr 2020

There is one side effect of this "retrofit" - one permanent fault in Aux. Heater (18).
0266 - Databus
U1121 00 [009] - Missing Message
[TIMEOUT mDachdisplay]
Luckily there are no practical consequences.
It appears that connecting Telestart unit without the overhead timer is the cause :whistle:

.
Normally as a standard factory option the overhead timer always comes with Telestart.
Next step is to work out coding modification which will clear this fault :thumbsup:

Dieseldonkey · 6 Apr 2020

@Robert

Does the auxiliary coolant heater have it's own built in pump, to circulate the coolant or is it a stand alone unit somewhere?

Robert · 6 Apr 2020

Auxiliary heater doesn't have a pump built in and it uses existing OEM pump on the coolant circuit.
The whole preheating process is triggered by Telestart and then controlled by Aux. Heater (18)
which communicates via CAN with any other associated components.
I hope this answers your question somehow

Is there an additional or uprated pump as opposed to the standard non aux heater pump?

I am not sure how to answer your question :unsure:

What are you trying to achieve mate?

Can confirm the cause. Disconnected my overhead timer panel - and as expected the same fault as above.
Did some coding experiments, however I didn't remove the "6E" from CANbus installation list.
Run basically through all the version codings + a few "unknowns" by changing the coding and then clearing the fault.

5800 = my current working coding, v1

5808 (byte 1, bit 3)

D800 (byte 0, bit 7)

5810 v2

5820 v3

5830 v4

5840 v5

5850 v6

5880 v1 + (byte 1, bit 7)

5890 v2

58A0 v3

58B0 v4

58C0 v5

58D0 v6

No luck with any of the above... :cry:

- your turn now

Thanks Robert for this.
I'm fairly new here, try to get this done without a telestart module, but instead using an app-control(VW T6 - APP-control for water-heater)
My question: what signal is going to the white/green cable in the red connector(pin1): is it simple +12V, or is it W-bus/Lin?

Thanks,

Jaap Stomphorst

Hi Jaap,

This is quite good idea although much more expensive.
Assuming that you are referring to this.

It is the Lin-bus cable which normally allows for communication between Telestart unit and actual heater(parking heater).
