Hi everyone! Well finally I sorted my problem! :) I finally tracked my problem down to a coding issue, my IHKA & Heater were coded wrong! My IHKA had the 'zuheizer' coded to k_bus & my ZHZ (Zuheizer) module was coded to 'konventionell' after changing my ZHZ module to k_bus to match my IHKA module my ...

[quote="X5 ALN"] [quote="wilkoturbo"] Arrrrhhhh no I ant got that !! Paulandnix@hotmail.co.uk Many thanks P [/quote] That was for Rob, do you need it also? I assumed you could undo your retrofit with DIS. Just PM'd you......... Send me your SA number and I will fire it in and see if SA536 is coded ...

[quote="X5 ALN"] You may need to change the cars ZCS to include factory option SA536 PARKING HEATER - however, it has worked for some - but did not work for me - it stopped my heater firing as it was looking for a changeover valve that didn't exist. So coding "might" work, but may also need ...

Hi X5 ALN, Thanks for that interesting info.... The Webasto unit I have is the common one we all share, the unit's sticker states its a Webasto z/c top. My problem to be exact is related to the fans, the red fan illumination symbol does not light up nor do the fans start at any point. You can watch ...

So.... A quick update on where I am with my head scratching problem...... Tried another Webo heater today on the car which worked the exactally the same as mine does, starts & runs when 12v is connected to Pin 1 but no kbus signal is sent to the inside to activate the interior fans...... Not sure if ...

Xman & Jaynana, huge thanks for taking the time to reply, it's greatly appreciated! Think this is a route to go down from now on.... As I can try before I buy I'm going to start a process of elimination and try to knuckle down on this error & what it actually means.... Hoping to try another havac ...

Hi X Man, Many thanks for you reply.... I also thought this could be a possible cause... I have tried with the fans on half way or even at max before the ignition is switched off.... But still no change to the situation...... I'm getting to the stage now where I'm thinking that this 'short to ground ...

Are you thinking hedgehog? Fans all work as they should on all powers... Hot, cold the climate panel seems ok tbh.....

Thanks again for the reply! Yes I've sat in the car whilst its running and nothing happens.... nothing at all with regards to the fans starting up etc..... Just been out & cleared the code from the memory & did a 'fuse pull' on the Webasto (Fuse47 in the boot) with the code not present ...

Hi Jimes256, Thanks for your reply! Hmmm..... I've not tried the webasto software on the car, I'm tending to think it's more car related than on the heater unit side of things.... The webasto unit has no faults at all when looked at through Inpa and functions fine when you run the live test ...

Hi everyone! Firstly can I congratulate everyone on such a fantastic forum, this thread in particular is by far the best and is the most informative on getting the Webasto Park Heater working! Can anyone help with my issue.... I have a 530d 2001 with the thermotop c with the additional water pump ...
