DBJoe996 replied to Sparkatan's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)^^Correct. The battery vent tube for the old lead-acid batteries. If you have upgraded to an AGM battery, the vent tube is not necessary.
The only fan under the dash on the passenger side is the HVAC system fan. Does the noise change when you increase/decrease the fan speed? Have you checked the cabin air filter for debris? The HVAC system fan is always on with ignition on unless you hold the decrease fan speed button until it shuts off. The next time you start up again the fan will be on again.
DBJoe996 replied to Eștii's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)You are probably going to get several opinions on this one. However, since you have to meet the stringent CA emissions requirements, and the cat pipe you are referring to has the pre/post O2 sensors, I would say that you need an OE or CARB certified cat as a replacement. You might be able to find a low mileage used one at a junk yard...DC Autos.
Drain some coolant (not all, just a sample), put it in a glass jar and let it sit undisturbed. Observe it and see if there is any separation of coolant and oil. Do the same for an oil sample. To firmly established whether your engine has D-chunked, a cylinder compression and leak down test on each cylinder needs to be done. Inspect the spark plugs carefully for coloration and replace them. Synthetic oil is hygroscopic so it will absorb some moisture (humidity) from the air. It is burned off when the engine reaches full operating temperature. If the engine has not run and reached full operating temperature in a while, could just be some "steam" you released when you changed the oil. If in fact your engine has fully D-chunked, it will run very badly and you will get misfire codes.
DBJoe996 replied to Kimm Murphy's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Get a passenger. Put a cell phone in video mode and run it all over the dash and underneath while driving. Pay particular attention to the A-pillar on the passenger side.
DBJoe996 replied to okcattleman's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)You might try this for the service manual http://audipages.com/911/wsm/
DBJoe996 replied to redcab's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Common cause for "it cranks but no start" is the CPS, crank position sensor. Does your tach needle bounce when you try to start? Also, check fuses/relays for the fuel pump.
Go to a Porsche dealer and buy a new filter canister and filter. They are selling them for less than $30 now. Do not run your engine with the bypass valve, which belongs in the bottom of the filter canister, removed. The oil filter will not function properly and will float in the filter canister allowing unfiltered oil to circulate through your engine.
Here is another forum thread with some good pictures and details DIY: 996 Door Latch Replacement [Detailed] - Rennlist - Porsche Discussion Forums RENNLIST.COM 996 Forum - DIY: 996 Door Latch Replacement [Detailed] - If your window does not stay lowered when your door is open, chances are that a switch within the door latch has gone out. This is a detailed procedure to change...
DBJoe996 replied to greg0078's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Have you tried an e-gas calibration? Turn on ignition to ON (not start). Wait 60 seconds. You should hear some whirring noise from the engine bay as the Throttle Body runs through a calibration cycle. Turn ignition off, then start as normal. The second thing that comes to mind is the change over in the resonance flap.
DBJoe996 replied to kbrandsma's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)How about #3 here Brake Master Cylinder Brake Booster Pre-charge Pump WWW.AUTOATLANTA.COM
There is a vacuum line to the brake booster right behind the firewall. Have you checked that? Might be a bad seal or something. See #10 here Brake Master Cylinder Brake Booster Pre-charge Pump WWW.AUTOATLANTA.COM
Which is it? Over on Rennlist you posted P0491 and P0492 drive while troubleshooting?
I don't know if it will help, but here is the CR 220 manual
DBJoe996 replied to RJ'sGottaDrive's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)From my understanding, cars are made like that. My digital and analog speedometer is consistently exactly 4 MPH faster than actual road speed. Confirmed by many roadside radars. I just adapt.
