AOS - Question

[911monty]

Thanks Markus I was trying to be optimistic that's why I said hopefully! I think there needs to be a sticky somewhere on the steps to take after an AOS failure, I modified your steps as a first attempt. Hope you don't mind


What to do: Do Not attempt to start the engine until all steps below have been completed as serious damage to the engine can result!

1. steps to take after AOS failure.

• If you have a Durametric or any other diagnostic tool note all error codes and check their meaning.
• Pull all spark plugs and clean them. There might me oil and crust on them. Check the electrode distance.
• Remove Fuel pump relay.
• Turn over the engine while the spark plugs are out. Aprox. 2 times for 5 seconds. Check if oil is coming out of the spark plug hole and how much.
• Put in all sparks plugs.
• Remove the MAF and clean it.
• Remove as much of the air intake system after AOS and MAF and clean it. There will be lots of oil in it.
• Install fuel pump relay. Start the engine.
• If it runs without unususal noises or anything else – OK.
• Do a test drive.
• If you have a Durametric or any other diagnostic tool check error codes.
• If you don't have codes or anything else – repair done.
