 Dear All,

I've just installed a Webasto parking heater (Thermo Top Evo 5) for my 3.0HDI. Itself the heater is working very well, but I have problem with the control of the cabin fan. The fan should be controlled by the BSI. A switched ground signal is required to the pin 6 of the 40VNR connector of BSI according to the wiring diagram (both original Citroën's and webasto manual). This signal is sent to the BSI when a controlled relay switching it, but the fan does not start to operate. The BSI configuration setting changed to "parking heater" as well.
Could you please help me what may the problem?

Thank you in advance!

 Not sure if its 100% same on 2.7 but I did it manually (as old C5 webasto instructions tolds): add 3 relays and +12V line from battery to fan cable connector (on LH front foot well, one small is to behind ac control-panel to cut CAN from the panel when car is not running (letting the fan to work).

Other relays are needed to control the fan (under bonnet, in ECU box to fan), the other cuts the webasto +12V line when car is running etc..

No need for costly PWM-relays from webasto IMHO.
