wizard replied to vnb282's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)I am no expert and am merely going by what I've read. On the assumption that the fluid drained was black, you really need to drop the transmission pan and change the filter. The Aisin transmission appears to have valve-body-related issues. From what I've read, the valve body is fairly easily accessed once the transmission pan has been removed. If it were me, that is what I would focus on as the least expensive and least difficult approach and hope that its repair/replacement solves the problem.
wizard replied to vnb282's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)As you may be aware, ATF expands as its temperature rises. Being absolutely certain that the fill level is as it should be at the prescribed temperature seems to be the easiest next step. Are you aware if the ATF and filter have ever been changed before? Do a search for 'Help finding a Valve Body' on here and read the Revmax post. That may prove helpful.
wizard replied to ToulouseNJ's topic in 997-1 Series (Carrera, Carrera 4, Carrera 2S, Carrera 4S)I seem to recall reading somewhere that it is now obligatory in France to have a breathalyser kit in the car. You might want to check that out if you haven't already. Bon chance!
As you are no doubt aware, there is a precise procedure for refilling the transmission to ensure the correct fill level. Your mechanic presumably knows that? If in doubt, it may be a good idea for you yourself to ensure that the transmission has been filled to that correct level; with the fluid at a temperature of between 35C and 40C.
As DBJoe996 originally suggested, I would get on down to Behbehanis for the electrical component to the ignition switch. Replacing that would be the least expensive and easiest first step ... and may even solve the problem.
I run Liqui Moly ... 5W-40. If it's on the approved oils list for the Panamera, perhaps give that a try.
In addition to the above, I recall somebody once experiencing instrument cluster problems on a 996 which were ultimately traced to frayed wiring on the fuel level sender unit. I see that your fuel gauge is showing reserve tank. Is that due to a need to refuel or a faulty reading?
Nothing else springs to mind, other than visually checking your coolant level regularly and perhaps inspecting the water pump. Depending upon how mechanically adept you are, removal of the serpentine belt which drives the pump and checking it for play/residue is a straight forward process on the 986. I don't know if that's the case with the 987. I'd still focus on ruling out the more mechanical elements before considering removal of the instrument cluster. Disconnecting the battery to see if that clears something that has been stored, and burping the system will do no harm at all. From memory, burping calls for the heater to be set to high and for the front fans to activate. I'm sure you can find the procedure through Google.
Welcome. It's very helpful to be as precise as possible. You have only now mentioned that the light is blinking. If one naturally assumes that not to be the case, the 'engine coolant temperature too high' would be a factor. Let us know how you get on.
Hard to say what it might be. It could be that the coolant was under-filled or, alternatively, it could be that you have a leak somewhere. Equally so, it could have been a defective coolant reservoir cap ('04' being the latest) ... or it could be a defect in the instrument cluster. It could be that you are getting an incorrect temperature reading. It's always best to rule out the easier things before moving on to dismantling the dash. I have a 986 so I don't know the layout of your engine. If there's a leak at the water pump, you'd normally see a (white) residue in the vicinity. 100,000 miles on the original water pump (if it is) is perhaps stretching it. If you are intent on 'burping' the cooling system, monitor the engine temperature and low coolant warning whilst you do it and, naturally, check the coolant level when the engine is cold. See JFP's post immediately below ... and his to you. He is an authority on Porsches. As he says, check that your fans are functioning as they should. If yours is the same as the 986, the fans at the front of the car are two-speed.
Yes, the burp valve is the black thing next to the blue coolant reservoir cap. Carefully lift the metal piece to the upright position and leave it there until you've run the engine to operating temperature. Make a note of the fluid level before and after. Re disconnecting the battery and the alarm, there should be a procedure for that in your handbook, failing which, do a search on here or Google. How many miles has the car done and has the water pump ever been changed to your knowledge?
Have you tried just disconnecting the battery for an hour or so and seeing what effect that has? If you have a burp valve, maybe run the car with it open and see if that has any effect on the coolant level. The new coolant reservoir cap presumably has '04' as its last two digits?
