if the fbh is activated when then engine isn't running and its above 5 degrees c outside then it heats the coolant water only and not the interior, thats why you only get cold air inside.. .. ... - .- -.

I reckon the fans were activated but the FBH did not start....

ashley. i was led to believe that above 5 degrees c only the coolant will heat, below 5 degrees c the interior heats as well...you might have found in your case the engine heated up quicker once you got going...and yes the fbh gets its fuel from the main tank..

Interestingly it was 6c tonight and I had to wait in the car for 15 mins so I thought I should try to see if the FBH would kick in and turned it on at the screen, at 10 mins It was still blowing cold and I reconed the 5c thing was true but at about 14 minuets it started to blow hot air.

Thx axle - I'll perhaps try that tomorrow morning. Was just cautious I did not flatten the battery this time. Ash

good point axle, maybe the fbh has to do its 30 minute cycle to work.. ... - .- -.

Am I safe to risk 30 minutes of battery life blowing the fans with no engine on..... |

It heats the engine coolant first and then opens a valve to allow coolant to the heater matrix when it's up to a set temp. The freelander one does the same but doesn't start the interior fan until the engine is up to temp, which is much cleverer. I have found on slightly warmer days it doesn't heat the interior at all, just the engine coolant. Also worth noting is that the engine temp gauge is not in the loop for the pre-heater circuit, so it will be a few seconds until the gauge shows the extra warmth - but then the gauge reacts so slowly... If you have an iBus reader/ Resler Interface you can run the free webasto diag SW, if you can figure it out! D ![]() |
