Need a bit of guidance.. I press the button on the fob and it goes red, green then flashing green, but nothing happens in the car. Am I doing something wrong?

Flashing green should mean the FBH is running.

Why it isn't is another story entirely.

Someone with more technical knowledge than me will - I hope - be able to give you some clues to follow. What do I put here then?

Forgot to say ... have a look at the Wiki on this site.

There’s info on the FBH. What do I put here then?

Zeppfish sent me this recently....

answers a lot of questions....first red light usually means replace battery in fob...but if you set it up in the car i.e. via the menu that will probably not work either as mine does the same with the green flashing light...its going to the dealers so will let you know what the fault is.... I need more help than most...sorry !!

I'd change the battery first - a cheap and simple step that eliminates one unknown.

i did that after trying re-pairing and asking lots of questions on here and lo and behold! FBH works perfectly!  Bish.
