    2008 cts clicking noise on top of engine

    Hey guys, I have a 2008 cts 3.6 DI. Recently I noticed that it makes a constant ticking sound upon ignition and the sound seems to also effect the sound of the exhaust, making it sound "rougher". The sound seems to be coming from above the engine towards the cabin of the car.The sound does not seem to go away after it is warmed up, but does diminish. It only has 44000 miles on it. Otherwise I have noticed no difference in performance. Anyone have any ideas on the issue or have past experience?
    Thanks!

    Its normal. My engine ticks away as well. Just the sound of the fuel going through injectors at such a high pressure

    Interesting. Because my new-to-me 2013 Coupe does the same thing. I have an appointment tomorrow morning at the dealer about it, and a few other issues. It'll be interesting to hear what they say. It just doesn't sound normal to me. If they say it's normal I'll want them to fire up another 13 CTS to confirm they all do it. I'll let you know what happens.

    I have an appointment at a dealership tomorrow as well. I thought I had read somewhere that with the DI that the sound is not unusual, but it seems to me that it is a little to loud and insidious. As with the sound the exhaust has when first started up. Thanks for the information, I'll post an update as soon as I hear some news!

    It is typical for a direct injection engine. My Audi does it as well.

    On the CTS engines, yes. What's odd is that my 2013 Lacrosse also has a DI engine and is surprisingly quiet. (it is the 3.6 V6 LFX engine) I was expecting the DI tick when I bought it too.

    Don't worry my friend it's just the Direct injection (high fuel pressure).

    I have listened to other cars with direct injection and they all have that distinctive sound.

    It must be something with the tuning of that engine IMO but I'm certainly not an engine expert.

    Well its at the dealer now. I'm fully prepared for them to tell me it's the way it is.

    It's also in there for the severe clunking and bucking the driveline does when I'm starting from a tight turn, but that's another thread!

    Don't be disappointed when they tell you it's normal. They can start every CTS on the lot and you will hear that distinctive clicking. It is louder on some cars than others. I'm on my 4th CTS and to tell you the truth I don't even hear it anymore. I guess I just learned to tune it out.

    Just talked to the dealer. Car is done and they, of course, said it's normal. I just never heard an engine be that noisy and evreything okay. Guess I have to readjust my engine ears!
