  1. I just realized that I am not as handy as I thought I was so the dealer will flash the coolant and replaced it. Porsche Autobahn in Fort Worth. So far happy with them. I will wait until I pick up the car Monday to see if they really did their job. I mean it is a long story but....
  2. Update. I took my car to the Porsche dealer in Fort Worth and after getting a quote from another place the dealer was cheaper. AOS replacement parts and labor $885 plus tax. Seems reasonable considering the other shop even though they say they specialize in Porsche, they quoted me $1,000 plus tax. I think I will want to flush the coolant and replace the coolant in the near future. Does anyone know if that is a job I could do or should I ask the dealer to do it?
  3. Thank you for the information and advice. I appreciate it.
  4. Thank you for the reply. Do you know if the oil will need to be replaced because the AOS will be removed and replaced? Is coolant also lost while replacing the oil separator? I have an experienced mechanic that I think he could do it, however he is not specialized in German cars. I am learning a little bit more every time something happens so someday I may be capable of fixing it myself. Thank you for your help!
  5. Thank you. Do you think is a job that I can do myself? Or only an experienced Porsche mechanic or any mechanic could do it. I found instructions with pictures on how to do it but I am new in the mechanical world and I am trying to learn. Is it really time sensitive to be replaced? Or you think I could wait a couple of weeks? thank you!
  6. So the AOS needs to be replaced. My 996 had the fvd Bronbracher exhaust, could that be the reason why? I bought the car with the exhaust already installed recently and it is possible the code was deleted by the previous owner and not disclosed to me.
  7. Thank you. I saw the coolant spray out after around 20 minutes of the engine running. I thought it was the connection with the hose, however later I realized that it seems the coolant to be coming from the plastic itself, from the top close to the hose connection, however the way it is spraying it seems like it is really coming from behind the hose which will be the AOS. I don’t have any idea about parts or how the flow of coolant works, however it seems the AOS is cracked and leaking coolant, so that is possible I guess? Also as long I keep watching coolant level and temperature is it safe to drive it for few days until I get it fixed? It is not a mayor leak and the engine does not overheat, however I think it is also affecting my catalytic converters as I just got the P0430 and P0420 codes. Thank you for your help!!
  8. Hello, I am really worried, I noticed a coolant leak on the driver rear side of the car. The leak is on the back. Starts leaking after the engine gets hot and it seems that stops after a while because I don’t lose that much coolant. I check the coolant and add a little bit before driving it. No overheating. at first I thought it was a hose coming out of what now I think is the AOS. But now I think is the AOS itself that might have a tiny crack. Is that possible? Coolant from the oil separator and not oil leak? How serious is this? Any help really appreciated. As much as I wish I could do mechanical work, I think this is out of my league. Thanks!
  9. Thank you! I really appreciate your help! I think I have the issue resolved. Now I have another issue. Coolant leaking from what I think is the AOS, I think for this one I may have to take it to the dealer. I just add a little bit of coolant every day. No oil leak just coolant. Is it ok to drive it for few days adding coolant daily and watching the temperature of the engine to remain low? Thank you!
  10. Hi! I am so new to this and not very good at working on my car, however my 2004 996 is flooding inside! I think it is when the AC is running, however I want to clean all drains. Please help me. How do I clean my AC drain? Where is located?
