Hi all,

Hoping you could help us out with our FBH on our 2010 L322.

Noticing that the FBH comes on with the remote however, is only blowing cold air. Asked my next door neighbour to check my battery and he states it's at 80% capacity (voltage not checked)

Wondering what further steps I could do to get to the bottom of this please? Any ideas / suggestions?

Cheers

Can you hear the pump start / run to supply the FBH with fuel ? Also check the level of diesel in your tank, not sure what level of fuel is required, but I once read on here that it will not run if the fuel level is too low. There are numerous possible reasons.

Also - check in the wiki section and carry out a search to find more info, there is a surprising amount of info to be found when carrying out a search, ie, typing in 'FBH not heating up' will bring up 71 threads on this subject.
