I too seem to get this noise on a cold start (or set the car to warm up using the FBH) and thought it was normal until i drove a newer ffrr and that didn't do it at all....

You need to clean the fbh out I had the same noise on mine before it broke at Xmas

Its a build of despots on the glow plug stopping it from staring quickly,

Cleaned mine when I change my fbh ecu

Now there's no sound at all, apart from a mini jet engine starting when standing out side of the car.  RANGE ROVER 04 TD6

Any threads or links to how or where the FBH is located and how to clean without fooking things up? Got a tendancy to be a bit heavy handed when doing DIY/maintenance and would rather not have to shell out to replace the whole unit cos i broke it!

Bit extreme but is it something that can be done by the dealer under warranty, ie. replace the whole thing?

Many thank JR - this sounds right to me. I can't believe the FBH is designed to sound like that! Moreover, I had a webasto FBH on my sailing boat and it never made a groaning noise like that.

You said you cleaned it and this fixed it - any chance you might be able to give some photos/instructions on how to do this as it seems a number of people have this problem and could benefit from your know how .

It would make a good Wiki for Martin or one of the other mods to put up there....

Many thanks in anticipation!  -----------------------------------------------
