A friend of mine has a brava 1242cc 80 (like mine) which he thinks that he has a problem. When he has a short journey and goes to a gas station to refill, when he opens the fuel tap air comes out with pressure. I dont know if he has a problem with the tap because tap should release the air pressure, and he dont want to change the tap because it opens with the blue key. Is there any chance to change the tap and keep the same key? Does he has problem to another part like charcoal filter or charcoal valve or to his multi-purpose valve (that is near the fuel pump) or he doesnt have any problem and this is normal to happen?

just a pressure release

i get it sometimes

So you say thats normal to happening? It suppose to happening automatically from the tap or i am mistaken?

Hi mate.
It happens to my 1.2 some times.
Especially when i am very low on petrol, or for no reason.
Nothing to worry about!

yeah, its normal.

all is ok. dont panic

Na se kala re Xristara apo Patra! O Apostolis apo Thessaloniki eimai! No panic for me just for my friend! Thanx everyone for your time!

Yes its perfectly normal. Its all to do with keeping emmisions low and preventing fuel vapour escaping into the atmosphere, because of this the tank does not have a "vent" on so petrol fumes build up in the tank. When the engine has warmed up, The ECU will open a solenoid valve to allow the fumes to be extracted into the air intake.

Nothing to worry about.

never happens to me!

It depends when you open it. You'll find it will rarely do it when the engine is warm, as the ECU will have vented the tank, however if you open it first thing before you go out in the car, it probably will do it.
