yeah, pretty much. my 04 is noticeable and my 03 isn't but it is typical. I've not checked the valve clearance (adjustable tappets?) on the 04, though. If you read about it on the forums, it's very much expected. Especially when it's cold!!

The injectors happily tick away at idle. If louder maybe just light valve noise. If quite loud but disappears upon FULL warmup (up to 20 min driving) then it's piston slap, a somewhat annoying trait of horizontally opposed motors with short (for fuel eco) piston skirts.

If REALLY loud...especially when revving quickly, then rod bearings from either past over-revving and/or oil starvation.
