4.6is ticking
 

Hi, so as most of you know I purchased an 02 x5 4.6is. it has 118k miles and is so far a great car. The only problem is a ticking noise that strangely comes and goes on the drivers side of the engine. I am completely aware of the vanos noise in this video but listen closely to the small tick. It is noticeable in the beginning of the video but goes away at the end. like I said, it comes and goes

Thanks!!!

That would be the fuel tank vent valve . It is a solenoid valve . Ticking can be variable .
It is mounted on a push fit rubber mount .
