What primes after leaving the car a while when you open the drivers door... I know the LPFP is supposed to but thought that's in the tank so would come from mid/rear under the car, i was thinking more in the engine bay as think that might be whats causing the squeak I have...
Cheers,
Dom

Hpfp too afaik. Hence, don't open your door when doing cam follower :happy2:
-
The fuel system primes when opening the drivers door. Hence why if you are changing the cam follower with the battery connected and someone opens the drivers door you get covered in fuel :laugh:
Edit - Or what Mike said :grin:
-
So what things around the fuel pump area moves when it does this?

The internals of the fuel pumps(s) are the only things that "moves" - apart from pressurised fuel in the system, hence the advice above about doors and playing with your fuel system

I've heard something adapting/opening/resetting under my bonnet too sometimes, so your not alone. However, I don't know what it is. It certainly doesn't squeak too lol. Only hear it if its in the garage (nice and quiet)
-
Are you talking about when you turn off & take keys out?
-
I'm not Mike no. It's when cars been left for (cough ages), when I open it then open drivers door, if I don't start it straight away, I hear buzzing and clicking.
I thought it was the throttle body, but I maybe wrong.

Please tell me how the HPFP internals "move" when you open the door.... Given that its operated by the cam shaft rotating. :evilgrin:

You are correct Rich. :smiley:

I only tend to 'notice' the TB Beeping, clicking & doing its thing after switching the engine off
