Mein Auto: BMW 740d (e65)
Red face Webasto / Auxiliary Heater : grayed out in menu

Hello,

I recently bought a 740d from 2003 and I retrofited a HW04 MMI on it just today.
Actually my car has a webasto/auxiliary heater but it is grayed out in the MMI climate control.

I tried to look inside of NCS EXPERT to see if the ECU was coming up, but I searched for SHZH and it was not listed.
What should be the good ECU name in the list ?

I read somewhere that if the webasto tries to start 3 times but fails, it locks himself and it is hard to unlock (perhaps INPA can do the job ; tell me).


That's it, you know everything, hope someone can help me with this.

Thanks !

Ok, so after reading many many posts, I found that there is 2 versions of the Webasto.
One Z (which is the version installed in diesel engines) and one C version (which the C stands for CIRCULATION).

So, i must think that my version is the standard one which only works for heating the coolant of the engine during cold days.

So, based on this post ( http://www.bimmerfest.com/forums/sho...d.php?t=665338 ), there is a way of adding the right parts to get the FULL CIRCULATING version.
But it seems to be a long work ... is it worth the time/price, i don't know.

By the way, this could explain why i can't seem to find the SHZH ECU in the list of NCS EXPERT, because the Z version actually installed in my car doesn't seems to be CAN BUS wired.


If someone already made this modification, please notify me as i would eventually go this way.



Thanks
