I can anyone tell my why i can some times smell petrol when i pull-up with the window down i cant smell it all the time just now and again. it does,nt mater if the tank is full or not, i don't think its a leak or i would smell it all the time, is it something on its way out thanks.

ive been told this is linked to injector seals breaking down. pretty common on petrols again so i am told lol

there does,nt seem to be a leak coming from the injectors would,nt it be wet if it was leaking there.

any leaks in the exhaust system?

no exhaust system is OK.don't smell it all the time.could o2 sensor be on its way out.

I have seen the gaskets / seals around the injectors have allowed the smell into the engine bay and into the cabin, check all the seals and make sure they are clean!

i can only smell it if the window is down

if you get the car onto ramps, can you check the underside and see if you can actually smell any petrol at all on the underside of the car, it could be that its heating the exhaust and a crack is expanding with the pressure allowing petrol / gaseous petrol to escape.

I don't smell it all the time just now and a again if it was a crack in the exhaust it would be blowing wouldn't it
