DBJoe996 replied to topmech0's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Thanks for coming back and sharing what resolved the issue. Helps others.
DBJoe996 replied to topmech0's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Basically the P1328 error relates to an open circuit on Bank 1. You will need to check the wiring harness connector, wiring, and may have to trace it back to the DME. First thing I would do is unplug the engine wiring harness connectors on the passenger side of the engine bay, and clean the connectors with some electrical cleaner. Do the same for the solenoid connector plug.

DBJoe996 replied to 2001996Tip's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I saw that you posted on Rennlist as well, and never got a response. The oil cooler is located way back on the right side of the engine. Replacing the four O-rings (2 for coolant and 2 for oil, and they are different sizes) under the oil cooler requires removal of the A/C compressor, then removal of the intake on Bank 2. You have to perform the same steps for installing and replacing the oil cooler entirely. Read up carefully on removing the A/C compressor because it can be difficult getting the bolt out behind the compressor. You need to remove the intake because you need a straight on shot up and down for removing/replacing the oil cooler. You will also need to drain some coolant so the level in the engine is below the oil cooler, otherwise you will contaminate your oil. And yes, you will need to support the engine with a jack, remove the engine mount nuts and lower the engine to the cross-member (as low as it can go still in the car) in order to gain enough room to remove the Bank 2 intake. The intake bolts can be difficult to gain enough access to remove. I have found it necessary to remove the rear bumper and heat shields to lower the engine as far as you can get it, without removing the mufflers/cats. Since the mufflers/cats are attached to the engine, it all comes down as one unit. You also will have to undo the connections for the O2 sensors so you don't strain the wiring lowering the engine. If you are going to tackle this job yourself, I highly recommend getting a Bentleys Service Manual for the 996. They are available on Amazon. You can see the location of the oil cooler in this picture taken from the transmission side of the engine. It is the silver looking "box" under the Bank 2 intake. Also, if the oil cooler requires replacement, only get one from a reputable source, i.e., OE Porsche. Some people have replaced the oil cooler with a cheap knockoff brand and found that they leak because the flat surface of the oil cooler is not flat and smooth like it should be. Given the work involved, this is no time to try and save money and have to do a do-over. I would replace the oil cooler and all O-rings at one time. You will need new intake O-rings as well, as well as a bunch of other items (such as Porsche coolant for a refill when done).

DBJoe996 replied to Myronf's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I pull my release and then walk back there and lift the engine lid with my fingers. It doesn't pop open and up like the front lid. It doesn't have anything to do with the strut, that just holds it up. Sounds like yours may need a bit of lubrication on the hood release mechanism.
DBJoe996 replied to Ewest112's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)On the back right side of the engine are the oil pressure sender unit and the oil heater/cooler sitting on top of the engine. Possibly one of those two are leaking oil. Head gaskets rarely if never fail on the 996 engine. If the oil seems to be all underneath the engine, check and make sure the oil filter is tight. The mayo in the oil filler tube is normal for a car driven in cold weather and not warmed up enough. I don't know why you would get codes for #1,2,3 cylinders that are on the left bank, unless you are having two different problems at one time. How old are the plugs/coils?
DBJoe996 replied to johnmh's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Thanks for coming back and sharing what fixed it. Good luck with the next issues.
DBJoe996 replied to Octane4evr's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)The AOS is a piece of garbage square plastic thing located on the back of the engine behind the left (drivers side) intake manifold. Total PITA to get to it, much less change any hoses attached to it, unless the engine is out. Coolant runs through it and there is a diaphragm inside to separate the oil side from the coolant water side. A faulty AOS is not repairable. Just have to replace the whole thing. Here is a diagram http://www.autoatlanta.com/porsche-parts/hardparts.php?dir=996-99-05§ion=104-10
DBJoe996 replied to spg356's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Go back to the last thing you did...swap out LED bulbs for standard bulbs. Some circuits do not like the LED bulbs and this could be one of them. Put your old bulbs back in and see what happens (because it wasn't acting wonky before you made the swap).
DBJoe996 replied to Aturcotte's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Maybe this will help http://911car.blogspot.com/2010/06/porsche-996-carrera-34l-o2-sensors.html Remember, the right side exhaust pipe is Bank 1, and the left side exhaust pipe is Bank 2. There are four O2 sensors, pre and post cat, and they are color coded black and grey connectors. So there will be two black and gray connectors for each bank pre and post O2 sensors on each side of the engine bay.
DBJoe996 replied to Mazenitani's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)I am pretty sure the Bentley Manual for your car has the complete wiring diagram. Search Amazon for Bentley Manual for your model/year.
DBJoe996 replied to TNT79Bronco's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)The first thing you should get is the Bentley Service Manual. Step by step instructions w/pictures https://www.amazon.com/Porsche-Carrera-Type-Service-Manual/dp/0837617103

DBJoe996 replied to Octane4evr's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Obviously something is wrong somewhere. When I have my Durametric hooked up and activate the Vario-cam on either bank, the engine runs rough but does not stall the engine. It does seem as if one, or both, of the Vario-cam activation solenoids is stuck. Maybe someone with more experience can weigh in. I don't know if this works but you might try turning the ignition on, not start the engine, and while listening underneath the engine where the solenoids are, have someone trigger the vario-cam on one of the banks and see/feel if the solenoid clicks.
DBJoe996 replied to B_Zerpersande's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Having done an AOS replacement on my car, you cannot access the AOS coolant lines without removing the Bank 1 intake. No way to get to those hoses and clamps, even with the motor dropped down to the lowest point. You might as well just replace the AOS while you're at it. The coolant lines #12 and #13 - #12 comes from the water pump and #13 crosses over and goes down underneath the engine. See diagram here http://www.autoatlanta.com/porsche-parts/hardparts.php?dir=996-99-05§ion=104-10 For a temporary fix, or total bypass of the coolant to the AOS, one just needs to plug the two hoses or find a way to connect them together.
