Hi Andy, Thanks for getting back to me, nothing to worry about then, can you tell me please what is a FB heater
Regards Nick,

Its a built in heater that kicks in on cold mornings to help everything warm up that extra bit quicker

It's automatic, and warms the engine in cold temperatures to aid the diesel engine.
The offshoot bonus is that a dealer option was Timed Climate ( with or without a remote) to pre-heat the car interior (to a moderate level) prior to walking out your front door. Some had it from new, but it can be retro fitted easily (forget what a dealer will tell you..)

If you use the second link, you will find members that can enable to the CCF for you and fit the remote kit (circa. £200).

It will defrost the windows in the bad weather and is a very nice addition that is popular with D3 and D4 owners. 2011 MY D4 HSE
