I had the Bonnet open and my hand on the compressor.

When I first fitted all the O-rings and the piston ring in the compressor it would bring it up to speed in a number of seconds but now there seems to be some delay before the compressor switches on and therefore the light flashes on the dashboard for several minutes.

Well! What happened there?

You hit Reply twice, so I've just deleted the duplicate post. Sounds a bit odd. The compressor is controlled by the pressure switch so if the pressure in the reservoir is low, it will kick in. It sounds as though pressure is low, so it isn't rising up and the light is still flashing, but for some reason it isn't detecting the low pressure and switching the compressor on.

Exactly what I thought.

Do you think the pressure switch is dodgy?

Wouldn't like to say, but it certainly looks that way. They don't usually fail though.

When driving with the tailgate open I get pissed off with the constant beeping and the dash telling me the tailgate is open, so I always flick the latch closed with a screwdriver so it thinks it's closed. You only need to flick the latch on the lower tailgate that the upper would latch into.

THAT IS VERY USEFUL TIP.
