FBH odd behaviour
It was cold one day last week - the car's temp sensor said 3.5C. When I got to work, and switched off the engine, I noticed the FBH was running. After about 15 seconds it switched off.
So, assume that it has worked correctly by activating itself due to the temp being below 5C.
However, it takes me 40 minutes to get to work, so the car would have got to operating temperature easily. Also, when I got to work, the temp was 7.5C. So why would the FBH still be operating when I got to work?
Is this normal behaviour? I always assumed that it would switch off once the engine got near operating temperature.
