Hi everybody, im new here and this s my first thread so please be patient..
1. I bought my first Porsche (2001 c4 convertible) 3 weeks ago i used to have a bimmer before, and i love it! the only thing that bothers me and i know youve heared so many times is the drone on 2k-3k.. lets say i DONT CARE about the sound on low and the high and i only care about no annoying drone on these limits (the car is a daily driver so i most of the times i drive on these levels) what would you recommand??
2. The car makes a noise when i lock the car in the fuel tank hole, something is broken i guess, is that the "996.605.203.01 Fuel tank vent valve (b1) " or im wrong? the noise when i lock the car drives me crazy..

THANKS EVERYBODY

I bought a 2001 996 back in Dec and noticed an exhaust resonance between 3K and 3.5K RPMs. I asked the mechanic about it and it is considered normal. I don't care for it either, though it doesn't bother me that much. I just chalk it up as a quirk of the car and I just avoid keeping the revs in that range for too long.

As for the gas tank door noise, there is a mechanism that locks the door when the car is locked to prevent someone from siphoning gas from your tank. It sounds to me like that mechanism is broken or failing on yours. I doubt it has to to with a vent. My guess is that it is the 996.624.113.00 Fuel door actuator -- a $25 part.

You can get rid of the droning noise by downshifting. Personally, I like the steady hum.

Oh, and welcome, but you need to post a pic or you will be banned. Well, maybe not banned, but you will be shunned and ridiculed.

He....he didn't post pics? Oh my gosh, that's the first strike. We better watch this guy.

I have found my car makes noise too
Having observed many situations around the world, may I suggest you only worry when you don't hear any noise from your engine after trying to start it?

Try something like plexus on the gas lid locking mech. You can find it at most motorcycle shops. It's used to clean plastics and revitalize them. It is nothing like the dreaded armor all killer of plastics and rubber. Make sure you shake the Plexus. It has some silicone in it besides other stuff.

Purchase? I don't see no stinkin' purchase..........

Block off the small intake hose with a cap. This will change the intake sound and ,may solve your problem. Just cap off the small intake to test it out.
Seach this form under "Orange Cap".

Congrats on your purchase and welcome to the forum. Please post the customary pic of your new car!

I'm not sure what to tell you about drone - my car doesn't do it. Or perhaps it does and I've gotten used to it. Either way, it doesn't bother me at all.

Pics or ban!

what exhaust do you have?

nice looking car, I think

This would be my first guess as well. The lock makes noise every time you lock the car--make sure there's actually something wrong before you try to fix it, though!

Something is wrong, I can't see pics?

Welcome and lets see pics of the ride!

Welcome to the happiest and most friendly forum on any 996 board anywhere (that is once you post a picture of your car. LOL!)

Let's be specific about the gas cap locking mechanism, for you. There is a plastic pin that is driven from the rear of the gas door opening, into a slot on the gas cap lid. There is a circular black plastic bushing with one flat edge that keeps the pin centered in its hole. If that bushing has slipped or is missing, the pin hits the metal around the door without actually locking it.
So first, check to make certain the bushing is:
A. There,
B. Properly snapped into the hole and the pin sliding smoothly through it. The flat edge touched the metal support, thus keeping it in place and aligned in the hole,
C. The pin slides through the hole on the lid without striking metal, or stopping short of locking the door,
D. Check to make certain the gas cap cover is properly aligned.

Ok, I am a newbie, I know, but I am jumping on your s@#T.

Congratulations and welcome to the great feeling of owning a Porsche, but where is the car?

No pics? WTF?
