I've had my '09 C2S for about 6 months and for the last month or so I've noticed clicking noise from the engine. I took it to the service manager at my dealer and they told me that it's a lifter and that it's not a problem as long as it's only noisy on startup. I'm hearing the noise almost all the time now. What do you guys think I should do? I either want it fixed or I want to trade it in. I figure if it's not really a problem then they shouldn't have a problem giving me a good value on trade-in. The next step I'm thinking of is to talk to my salesman instead of the service manager.

 

Why would you trade it in if it can be fixed? Have it repaired and keep the car.

 

Does it continue after it's fully warmed up? If it does, do what they say -- take it in to have it corrected. Don't throw the baby out with the bathwater. If you've had your 09 for only 6 months and are already contemplating another car then you should sell the Porsche and never buy another one.

 

Just a thought and you would think the dealer would know but... The new DFI system sounds like a ticking sound due to the high pressure it uses in supplying fuel. I know what the sound is but I have had several people ask me if I had a noisy lifter or a valve train issue. I know this may be pretty simplistic but I wanted you to be aware of the DFI sound which is different from any previous 911 before you go and sell a good car. You stated, "I've had my '09 C2S for about 6 months and for the last month or so I've noticed clicking noise from the engine." I lived in Houston for four years and I bet for the last 6 months you have been blasting the A/C! In the past month the weather has been cooler and you may have had the windows down allowing you to hear the tick. Could it be possible you just noticed it but it has been there all along? Just trying to save you some $$$ if possible. BTW, I have an '09 C4S.

 

This is an excellent bet.

 

The service manager has told me that it is a lifter that's making the noise. He recommended to not fix it unless I hear it all the time. I don't hear it all the time but it's not just when it's cold or when it's just been started.

The reason I'm thinking of trading it in is that they are telling me that it's not a problem. I think it is. If they don't think it's a problem then they can have it and fix it themselves. I'll get another one.

 

Just replaced the lifters on my 996, not too hard a job. But the dealers/mechanics have virtually no experience wit the new 997.2 engine. So this is a whole new ball game to them. I would ask the area Porsche rep to get involved. If the lifter is noisy now it is not going to get better.

 

If you trade that car in now you're going to take an absolute bath on the trade in value. You'll probably lose 20-25K from what you paid. Your mechanical issue is not going to cause them to give you more than it is worth. They can only give you wholesale value, not matter what. They aren't going to take a loss on a trade. Get it fixed. Persistence pays off.

 

Mechanically it's just an engine i.e. a big vacuum pump. Lifters are lifters and the way they work doesn't change. It's still an H6 while there may have been some design changes as far as the cylinder block and crankcase assembly is concerned, it's still an engine. Nothing really special here and you diagnose them the same way.

Agreed that if it's noisy now it will only get worse.

Don't worry mate, you don't have to trade your car. The noisy lifter has been a common problem for most of the old car users.
An article from a reputed website says:
So, a quick check of the valve train will tell you if there’s something physically wrong with one of the parts. If not — it’s likely that a flushing agent and an oil additive added to the fresh oil will do the trick and silence your lifters.

Then going for the oil with the density prescribed by your manufacturer will be your best go. Again I recommend changing the oil density to other than what the manufacturer recommends can make the oil too thin or too thin. Neither of them is good for your engine.
