Webasto Auxiliary Heater - customizing

[mr.needs]

Hi @oldiebut goodie. Do you know if the T100 HTM / TC4 is compatible with the VW firmware? Or does it need special Webasto firmware loaded onto the heater?
I just installed the T91 remote and Telestart, but like the idea of being able to control the heater from my phone as well.

T91 max time is 120 minutes, cannot be increased over that.
T100 HTM max time is C5 which isn't converted to minutes in any documentation! ( But is 120 mins ) You have an indication of the fact that the heater is operating in the display.

Timing is all dealt with by the receiver not the heater.
Using the T100 HTM is a lot more preferable to using the blind remotes ( T60 - T91) and satisfies the need for yet another gadget. I am surprised that everyone is still plugging away with the old ones for their heaters. I wouldn't be without mine although it doesn't get much use. I might have fitted a Thermocall TC4 if I had a mobile phone!

Theoretically it should work BUT:




In the installation instructions they say that function cannot be guaranteed! If you have a W-bus connection it should work provided VW hasn't blocked the signal at the ecu with their own coding. It would take someone other than me to test - I only work on the air heaters anyway.
I have sold the only TC4 system that I had coupled with an air heater but as I have not got a OEM water heater or mobile phone/sim card even I couldn't test what would work and what wouldn't.
I much prefer to see a separate standalone heater installation from the start rather than having it all tied in to the vehicle's system as it is far more versatile then and you then don't have all that messing around with VCDS or others.

You say that you have added the T91 Telestart - which one have you added as there are 3 versions, 12v, W-bus or LIN-bus?

It’s the OEM ersion. I think it’s LIN-bus, but not 100% sure...

My quick bit of googling suggests that W-bus is a priority Webasto protocol, which is not compatible with the open LIN-bus protocol?

 

[oldiebut goodie]

I am not so sure either - this advert that I turned up says it is W-bus for the 3Q0963513 version. The more that I read of the various Telestarts being applied to OEM heaters the less the certainty that such and such a Telestart will not work - this has been on various marques not just VW. I have read of the same remote and receiver both working and not working correctly on different identical OEM heaters so it does appear to be very hit or miss as to what actually works.
If yours is set up with W-bus already you should be good to go with anything else W-bus.

This documentation of the T91 suggests that the max time is 120mins.
car-technical-documentation-telestart-t91.pdf

This is the document that suggests that it is possible via the keyfob to check and set the running time as well as getting feedback about the running status of the heater.

I have fitted my heat exchanger at the back today and wired up the telestart.
I will attempt thecsoftware side on Thursday when I am off work BUT I have gone through everything and I do not understand the webasto firmware update.

How do you do the firmware update. You are all far more clued up on this then me. I have VCDS and can work that but there is no mention of flashing the firmware with vcds and no one has shown how to do it in vcds.
I only have vcds.
Please help a dumb guy out please.

 

[markob]

Pretty sure you cant use VCDS for doing the software ‘update’. Think you need VCP or ODIS-E.

@mmi or @Robert can confirm..

Correct.

 

[oldiebut goodie]

If you are only swapping the .PRN data file it is easy enough over W-Bus with the WTT 2.16 engineering mode version program. 30 seconds to program. Can't do anything much more though.

 

[bullracing]

thanks. Thats great but means absolutely nothing to me. I need to know how to actually do it. I've never heard of WTT 2.16 engineering mode version program.

I do have one of these I brought ages ago but there is no info as to how or what I do with it or where I plug it in. I dont seem to have the right/same cable as the one below (have attatched what mine looks like) or I have no idea where it plugs into.

 

[bullracing]

ah bugger. I have just looked at ebay listing and it says night heater not parking heater. Bugger. Brought the wrong kit :-(

 

[Robert]

What are you trying to achieve?

 

[bullracing]

From reading the numerous threads I need to upgrade/update the webasto water heater so I can use it as a parking heater to work of the remote control. I can do the vcds side but i need to do more software stuff?

To complicate it further my long term goal is to be able to turn the webasto on and use the water to heat a heat exchanger to have a shower. (I have today fitted the heat exchanger/shower and the telistart) So im now trying to figure what I need to do to get it all working via the software vcds side. Hardware has been fitted now so its just the coding side.

Just to understand your current setup.
Would you mind to post your up to date VCDS autoscan?

 

[bullracing]

I will have to do it when back at the van on Thursday but I was hoping to figure out what I needed to do before hand so I can go and get it done. Here is one from the other day. I have now sorted all errors, It was while I was coding cruise and mfsw.

I have fitted my heat exchanger at the back today and wired up the telestart.
I will attempt thecsoftware side on Thursday when I am off work BUT I have gone through everything and I do not understand the webasto firmware update.

How do you do the firmware update. You are all far more clued up on this then me. I have VCDS and can work that but there is no mention of flashing the firmware with vcds and no one has shown how to do it in vcds.
I only have vcds.
Please help a dumb guy out please.

What exactly have you purchased so far?
And what has been installed? Extra details?

I have purchased and installed this

NEW OEM Webasto Telestart T91R LIN 5Q0963513A kit with VW Remote | eBay

VW Remote - T91R part number 5Q0963511. Car model and model year still has to be verified. 1 x Remote 5Q0963511 T91R with VW emblem (with battery inside);. There are 2 modifications of Webasto heaters, installed in VW vehicles originally.

www.ebay.co.uk

I have a 2016 shuttle which is now a camper, the rear heater has been removed and I have fitted a heat exchanger instead.
I can do the vcds coding but I do not understand what or how I do the webasto firmware update. If I cannot do it via vcds is there a way to do it without having to pay out for ODIS or VCP? How would I connect to it?

I have purchased an Danhag diagnostic interface for a T6 but it seems I have brought the one for the air heater and not the water heater so that option is no good I guess.

Where are you based?
@stoem has done this recently. Maybe he would be willing to help you?

[oldiebut goodie]

thanks. Thats great but means absolutely nothing to me. I need to know how to actually do it. I've never heard of WTT 2.16 engineering mode version program.

I do have one of these I brought ages ago but there is no info as to how or what I do with it or where I plug it in. I dont seem to have the right/same cable as the one below (have attatched what mine looks like) or I have no idea where it plugs into.

That is their version of a W-Bus adaptor dongle - you should be able to use the WTT program to change the .PRN data file with that, I say should but I have never used one as I use the genuine Webasto gear.
Find your W-Bus in the connector and give it a try. W-Bus isn't just for air heaters, I am using it at the moment on a Webasto Dual Top water heater.
