2006 Sport. VIN SALLSAA146A934562. Having problems with excessive diesel being burned and clouds of smoke. A replacement would cost £800.00 and I understand parts are not available. If the problem persists would it be safe to unplug it or perhaps take out the fuse? Andrew Kennedy

Parts are available,,, although not very cheap. I had issues with mine leaking which was causing excessive smoke so I unplugged the two connectors,, taking fuses out was causing other issues, unless I pulled the wrong fuse!. 2010 RRS, TDV8

Hi,

dont forget the FBH is not just about getting you warmer quicker its main function is getting and Keeping the engine up to operating temp quicker, many dont notice or realise that the the FBH can operate a number of times during a journey if slow moving or frequent stopping and starting, so a none functioning FBH will also potentially use more fuel as the engine is not up to temp

As said they can be stripped and cleaned but excess fuel may be the FBH fuel pump ?

if you want to get serious about it there is has its own topic over on D3
