Fault Code - Auxiliary heater control module B1D29
Hi Group, can anyone assist please....
I've recently had my LRD 3 diagnosed and fault code store downloaded following an intermittent engine management warning light (orange), this at the same time as replacing the battery.
the only two faults detected were in the:-Auxiliary Heater Control Module
1) B1D29 No start, even after restart attempted - intermittent
2) U1A44 Fuel Level - intermittent
Mr RAC man was struggling to diagnose these but thought at least (1) above was related to the fuel fed cold starter module...
has anyone come across this before and what the fix may be?

The first one is quite common, and the first advise is to just clear it. (I think removing the FBH fuse will do this? if you don't have a code reader)
The second. Not sure. But the FBH won't start if the fuel is low (not to waste it) so that's not going to help

Thanks Pete, I’ll pull the fuse and try that.. RAC man did try to clear the fault on his PC but it wouldn’t clear..all other faults set after a flattened battery were cleared ok... I may get the unit off and give it a quick recondition...
pulled FBH fuse with no success... tempted to take the unit off and give it a fully clean if poss.. although it wont explain the fuel intermittent fault that's listed on the diagnostics screen....
