There are only a few ticking sounds that are "normal" on this car.

1) Injector ticking, they make noise, it is normal.
2) Fuel pressure release valve, also sounds like injectors ticking. If you rev the engine it will go away and return.

Any other rattles near the exhaust are usually wastegate rattle. It is normal in the sense that it is a common problem on these cars. Bring it to the dealer if you are under warranty and stock.

Any other excessive ticking noises may be valve train noise. Go to dealer if it is a concern but they will likely do nothing unless its excessively loud or throwing codes.

The e36 and e46 problem were notorious for needing valve timing adjustments as early as 20,000 miles, but the N54 doesn't have that problem.

thanks jeff, the more i talk to people im leaning towards #2 you listed, but why would this start now and notoccur in the first 5 years ive had the car?

i will say the car has never been in weather that is this cold before if that makes a difference, i store it but drive it around my parking garage once a week.

My car makes the same ticking noise and when I rev the engine from idle it goes away and comes back a few seconds later. It has been making that noise ever since I bought it. I don't hear it all the time though. Car runs and performs fine so I'm not worried about it.

Happens to my car as well. I also figured it to be something fuel related, and probably not much of an issue. I had a Mazdaspeed6 (also DI) that made a similar noise. Not anything I'm worried about.

mine makes that exact noise as well. TO me it sounds like every other direct injection car ive ever worked on so i just count it as normal
