FBH Reset Tool

Hello has anyone got a reset tool for the FBH lock out (or now of somewhere to take it too) near Swindon Wiltshire, have been guilty of letting the fuel light coming on too many times - Needed it to work this morning and alas it didn't

Also thinking of getting one of those timers fitted, Bodsy do you ever get Swindon way?

thanks

May be shot down in flames here but I think the FBH does not lock out permanently after a certain number of low fuel incidents (urban myth).

Have looked in the workshp manual and such behaviour is not mentioned- only that it locks out until the fuel level is restored. It is more likely being switched off by the battery management system if your battery is a bit low on charge or it is just clogged up following a long period of not being fired up. Fill up with fuel and charge the battery and you may find it starts working.

If still no smoke then a diagnostic computer can be used to initiate a purge which should get it going. I have seen a work around described on the forum somewhere using a home made loom to fire it up but you'll have to search around a bit to find it. Bodsy will probably be along in a minute to provide a better answer! 2008 MY Java Black TDV8 HSE

The heater will not attempt to run if the fuel level is too low Thumbs Up

providing there are no other issues, it should fire itself up when you refuel

A couple of winters ago I had the very same issue, I fixed it on a very cold morning by starting the car, waiting for the FBH to kick in, around a minute, and then turning the car off again, I waited 5 minutes for all the huffing and puffing to stop, and then repeated the procedure, I did this around 15 times untill the FBH finally ran on its own, you should know if you are getting close to success as the FBH generates a lot of smoke before finally kicking into life 07,TDV8,Black, Black Heated leather all round, Rear Entertainment with Headpones & Remote, TV, DVD, Pure Dab Digital Radio, Sidesteps, Adaptive Headlights, sunroof, now working fuel burning heater Smile)))

Agreed. There is a lock out mode but it is for more serious issues (thought I'd include it here for the reference of others without the manual):

Quote:
Diagnostics
The control module monitors the FFBH system for faults. Any faults detected are stored in a volatile memory in the control
module, which can be interrogated by T4 via the medium speed CAN bus. A maximum of three faults and associated freeze frame
data can be stored at any one time. If a further fault is detected, the oldest fault is overwritten by the new fault.
The control module also incorporates an error lockout mode of operation that inhibits operation to prevent serious faults from
causing further damage to the system. In the error lockout mode, the control module immediately stops the auxiliary fuel pump,
and stops the combustion air fan and circulation pump after a cool down time of approximately 2 minutes. Error lockout occurs for
start sequence failures, combustion flameouts, heat exchanger casing overheat and if battery voltage is out of limits. The error
lockout mode can be cleared using T4, or by disconnecting the battery power supply (connector C0926) for a minimum of 10
seconds.

Start Failure and Flameout: If a start sequence fails to establish combustion, or a flameout occurs after combustion is
established, the control module immediately initiates another start sequence. The start failure or flameout is also recorded by an
event timer in the control module. The event timer is increased by one after each start failure or flameout, and decreased by one
if a subsequent start is successful. If the event timer increases to three (over any number of drive cycles), the control module
enters the error lockout mode.

Heat Exchanger Casing Overheat: To protect the system from excessive temperatures, the control module enters the error
lockout mode if the heat exchanger coolant temperature exceeds 125 °C (257 °F).

Battery Voltage Limits: 10.25 - 15.5 volts.

2008 TDV8 - it was a labour of love and is much missed

Had the heater reset this morning by local webasto dealer, he told me that it was locked out and had a few codes, every thing looks good now, he said 'as the car is hot, the heater would not kick in so check in the morning and see what happens, if it does not work come in tomorrow morning' so we will see! About to get into a sport
