Ok, found time to Look into this PCB today and was going to remove it and send to French MIke after suggestions to do so on here ........but where the hell is the little black box containing the FBH PCB ? ,
looking at other posts and pictures I thought it was in front of the battery on nearside .....I have nothing resembling this black box

I have done a search but cannot find any posts showing where it actually is can anyone help as it's getting dark now and I'm running out of time ..

I seem to recall reading its part of the FBH.

pretty sure its integral to the control unit/heat exchanger on the FBH, so you will need to get under the wheel arch.  There is nothing that can't be fixed with a hammer😜😜

Yep I sent mine to France last year.

You need to remove the FBH from behing the passenger wheel arch.
Join the two hoses with copper to complete the circuit, then take the pcb out from the FBH and send it off.

Yep fbh is behind the left front wheel, below the battery. The PCB is on top of the fbh heater, but has to come out to get it !!!

Thanks Chaps,

Thought it was to good to be true when I heard it was right on top in front of battery ......


I presume it will empty of water then when removed ?

Yep. Need to patch the flow and return lines together then top up coolant. Squeeze off the hoses before you remove it to reduce the coolant loss.  There is nothing that can't be fixed with a hammer😜😜

Thanks for the tips chaps ,

Is there any way you can get to this by removing the battery and tray as I only need to get at the top part to remove the PCB for French Mike (I'm not with the car so cannot check)

Presuming it's this type of FBH and I need to grit into one of the black boxes on top ?

i am sure somebody on here said that the pcb can be removed from the top without removing the whole fbh

Yes me too,

I've tried a search but haven't found it ..


Anyone confirm if it can be removed from above without disconnecting the Webasto ?
