I think the tv in motion takes a while to work because the system needs to fully power down and then ot will be enabled.

For parking heater, run it from the car and open the header tank and check to see if your getting a jet of water recirculating.

Tv in motion is pointless to be honest as the signal can't keep up on the move. Only real use is when your stuck in traffic, saves you putting the handbrake on if your in slow rolling traffic.

ok been reading this with much interest.....here my problem ..
iv not got the heater option on my screen only the vent option
iv got the letter z on my webasto.
iv got no remote control
when the engine is running the webasto heater is hot to the touch.
why oh why every time i open a door does the webasto start up and run for bout 30seconds.....it doesn't get hot ,it just sounds like a fan blowing.

You'll need to run some software to find out

We after a lot of messing around finally got my parking heater to work again...

Changed the fuel pump, glow plug, still no joy. Turned out to be the circuit board doh.

Anyhow anyone who need to do some advanced diagnotstics I can confirm the following works, get yourself a reslers ibus interface (http://www.reslers.de/IBUS/install.html) hook the ibus wire to the kbus pin 3 on the heater, and the Webasto Thermo Test software (http://www.techwebasto.com/heater_thermo_test.htm) and you can test everthing, pump, fan, burner,pcb etc.

By the way anyone needing a second hand glowplug or fuel pump PM me I have spares

Any detailed instructions for that? I have a riesler and navcoder. Riesler is plugged into the back of the nav unit in the boot with a splitter cable I made. I'm sure that's ibus connection. Is it deffo a kbus connection needed direct to the webasto?

mcc05, this is REALLY interesting!! cos mine does the following when i try:

starts, blows cold air through the exhaust, doesn't get hot, and shuts down. it records a 'glow-plug fault' when i check with the scanner.

but reading through many threads i know its just a generic error that BMW registers when there's no flame. so not necessarily a glow-plug issue. it could be the glow plug, fuel pump, or even the circuit board like you say!

so the unit you've uncovered may be able to pinpoint what or where the failure is?

in the site it specifically says 'Do not use the KBUS if you can't find an IBUS wire!!!'

what's that supposed to mean? anything to worry about?

Which version of software do you need to download?

I know it says "do not use Kbus" but I'm sure that is related to running something like Navcoder. the Termo software is specifically written to talk "kbus" as ping 3 is kbus not ibus.

Yep it certainly helped me, from the software I could, activate the fuel pump see fuel coming through, active water pump, active air pump. and test the glow plug, which showed a fault "flame decetor", even though with a multimeter it had the correct ohm value ~0.4.

I simply connected my interface (rs232 version) to the +battery and - under the bonnet and the ibus line to pin 3 of heater. run up the software and set the correct heater type and away...

[quote=""dirtymonkey29""]Which version of software do you need to download?[/quote]

Just got the latest version...

Instructions say pin 2. Is it the white/red/yellow cable in the webasto plug? I take it you connected live and earth too

NOTE My Error pin 2 NOT pin 3 !!!!!
And yes + and - connected up to battery points under bonet next to heater.

thx, so how did you conclude that the fault was in the pcb? was that also possible with the test software, after it indicated the fault as 'flame detector'?

cos that's no better than the scanner saying 'glow plug error'.

Because even though the glow plug meassured ~0.4 ohm with a multimeter, the software showed no reading for the resistance of the glow plug, i.e circuit board not reading the glow plug resistance....

Not sure it will help me. My webasto works as it should under normal circumstances i.e 5c or less. Just doesn't circulate around the matrix and heat the interior with 12v to pin although it fires up, runs for a bit shuts down for a bit and runs again. I was thinking maybe the water valve (the one that looks like a double solanoid) but again I have no problems getting heat into the cabin when the engine is running. There is an extra plug coming off the one that's plugged into the water valve that goes nowhere. Can anyone who's works proper and gets hot off pin 1 tell me if they have the extra plug plugged into anything?
