Error MF2

[Gert_]

Hi, long time not been here (is good perhaps ).
But now a question. My (very old) MF2 goes on error. With power up, the system pressurizes and the led goes off.
Few seconds later, the led comes on again!
So, what is the diagnostic checking? Only pressure? Or other things too?
Anybody knows this?

Kind regards,

Gert

It look as the system cannot sustain the set pressure, there is a small leak some where.

Thanks.

Disconnected the blue loom and switched on Ignition. For some reason the jet did not spray regularly, but after a few seconds she showed a nice continues spray.
So, I assume there was some air in the piping.
No idea why. Never had this before and remember, the kit is about 20 years in the car.

You could be right, air in the system will cause this.
