new weird sound

So this morning on my way to work I noticed a new sound coming from the engine compartment. It sounds like a faint "chug chug chug" that goes faster as I go faster. At freeway speeds I can't really hear it. At idle it's "chug chug chug..." like maybe a belt has frayed and part of it's hitting something or perhaps a bearing problem. It's not loud, but very noticeable. I've driven about 50 miles so far. Any ideas what the problem might be? Should I take it to the dealer immediately? TIA.

It could also be an alternator. I just replaced one on Friday for a noise that could only be heard at idle. BTW why would you take it to the dealer?????

Should I take it to Flintworks instead? I have looked into independent mechanics before and what I've found was that with the 10% discount I got from the dealer the prices were comparable, with sometimes the dealer being less. For example I called Kahler's and asked for a quote on changing the spark plugs, serpentine belt, and fuel pump (60k service replacement items), with me supplying the parts, and they quoted me a price slightly higher than what the dealer (Michael Stead Porsche) wanted.

BTW, I can hear the sound at idle and driving around town. The sound "gets faster" the faster I go. It sounds like it may be the water pump? Does the sound mean the water pump is broken or about to break? Temperature reading has been normal.
