Pulled my L322 TD6 into garage today and noticed smoke coming from tube underneath passenger side of car after switching off. What is this off??
 
Just spotted that now, couldn't understand what he meant the first 3 times round :rolleyes:

[smile] When in doubt - RTFM [/smile]

A Fuel Burning Heater (FBH) system is installed as standard on Td6 models and as an option on V8 models. The FBH is a supplementary heater installed in the heater coolant circuit. The FBH can be operated without the engine running to pre-heat the passenger compartment and after the engine starts to reduce the heater coolant warm-up time. On Td6 models, the FBH also boosts the heater coolant temperature while the engine is running at low ambient air and engine coolant temperatures, to maintain heater performance at an acceptable level.


The system consists of a FBH unit, a FBH fuel pump and a changeover valve. On vehicles with the remote operation feature, the system also includes a FBH receiver and a remote handset. Fuel for the FBH system is taken from the vehicle fuel tank, through a line attached to the fuel tank's fuel pump unit, and supplied via the FBH fuel pump to the FBH unit. In the FBH unit, the fuel delivered by the FBH fuel pump is burned and the resultant heat output is used to heat the engine coolant. The changeover valve isolates the heater coolant
circuit from the engine coolant circuit

An ECU integrated into the FBH unit controls the operation of the FBH unit and the FBH fuel pump. The ATC ECU
controls the changeover valve. System operation is initiated by:

1.The instrument pack, via the ATC ECU, using I and K bus messages, for parked heating selections made on the Multi Information Display (MID) or Multi-Function Display (MFD)
2.The remote handset, via the TV antenna, TV amplifier and the FBH receiver, using radio and hardwired signals, for instant activation of parked heating
3.The ATC ECU, using K bus messages, for additional heating while the engine is running
