Ticking From Engine Compartment

I've noticed a ticking noise coming from the drivers side area of my engine compartment. The noise sounds like a solenoid clicking at a set period of 1 to 2 seconds apart. It is only noticeable at idle and happens at any temp. It does not sound like valvetrain or injectors. Here is a link to the youtube video I made of it. I've seen similar videos and done searches but haven't found anything other than "it's normal" or it's the injectors". What are your thoughts?



The engine seems to be running fine and there were no engine codes thrown.

I am no mechanic, but I do not believe that is normal. Hopefully it is nothing major. I have a 08 328 coupe and it does not do this. There are a lot of knowlegable people on this forum. Hopefully someone here will be able to help you get an idea of what it may be before you take it to a shop.

I think it's been decided that this noise is from the lifters.

Thanks for the replies. Wouldn't the noise vary with RPM if it was the lifters? This noise remains at a constant 1 to 2 second interval regardless of rpm and goes away after 1000 rpm.

That does not sound like lifter noise, it would vary with rpm. The time between the tick is too long.
