That is not true oil and water being mixed can come from many different places. Such as a bad radiator which would cause transmission oil to mix with the water also alot of audi's have a water cooled oil cooler which are a very common cause of oil being mixed with with water. These type of oil coolers are located under you oil filter. They have water lines hooked to them which cools the oil and when they go bad the water and oil will mix. So dont be convinced that its your head gaskets it could be but not as likely. You can pressure test your oil cooler to see if this is the problem just romove it an plug one off the inlet or with rubber plug which can be purchased at you local hardware store (I found mine at ace hardware in there specialty drawers where they have all there bolts) then attach a air hose to the other outlet pressureize the system and place it in a bucket of water. this should tell you if the oil cooler is bad but be careful not to ove3r pressureize the cooler this could damage it and caust it to leak. 15 to 30 psi should be plenty.

I suggest you to do an ecm diagnostic to see if you have any codes stored. After that you can go from there, you might have an issue with the theft system.
good luck.

When was the last time you had the timing belt replaced? If it broke, you likely have internal damage. Hope it's something else, but this is a possibility since it had a belt and not a chain.

Sounds like you have either a shorted fuel pump driver ground or a sticking fuel injector or injectors. Remove the injector electrical plugs and see if it still flood if it does then then one or more injectors are defective, if not then the engine wiring harness is grounded to one or more injectors or the PCM (powertrain control module) is defective. Remove the spark plugs to ID which cylinder is defective, disable the ignition system when you do this or the gas squirting out the spark plug hole can ignite (been there)

You may have fuel coming out but do you have enough fuel pressure? Also have you checked to make sure you have spark?

Certainly. Get the Haynes Repair Manual on your vehicle from the local Auto Parts store and it will explain the steps in each service and identify any special tools that may be required.
