United Kingdom 2014 Discovery 4 3.0 SDV6 XXV LE Auto Causeway GreyDiscovery 4
Fault code B1D26-93

Thought I'd just check for any faults before my D4 goes in for it's service and it came up with an AHCM Aux heater fault B1D26-93 (6C) Combustion Air Fan Circuit - Component Failure - Non Operational.

Has anyone any ideas as to exactly what this might be and are there any usual suspect components that do fail? D4 MY14 XXV - RLD/IID BT
D4 MY13 HSE Lux - RLD/IID BT
P38 RR - Sad parting
110 - Even sadder parting
S3 88" - Still going strong after 23 years of ownership Smile

According to manual:

Quote:
- Using the manufacturer approved diagnostic
system, record then clear any stored
diagnostic trouble codes then conduct the
fuel fired booster heater operation check
(Setup and configuration/auxiliary
heater/operation check)
- Check for reoccurrence of the diagnostic
trouble code
- If the diagnostic trouble code reoccurs
check and install a new fuel fired booster
heater module
- Refer to the warranty policy and procedures
manual, or determine if any prior approval
programme is in operation, prior to the
installation of a new module/component

If I were you I would clear the codes and then see if it happens again.
Hope that helps.

Thanks Promitheus, you're a star Thumbs Up Cleared the code, then ran the FBH from the remote. All seems fine again. Must have been a software glitch Bow down D4 MY14 XXV - RLD/IID BT
