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.

When the airbag light (SRS) is on or blinks it means a fault has occurred in the system and the airbag diagnostic monitor has disabled the system, the most common problem that turns the light on is a break in the connection to the steering wheel mounted airbag, this is due to a rotating ribbon contact that breaks under the steering wheel that connects the airbag to the wiring harness and the diagnostic monitor, the part is called the clock spring contact, a coiled up ribbon electrical contact that turns with the steering wheel while maintaining a mechanical connection to the airgag mounted on the steering wheel, to replace this part you must disarm the airbag system and remove the steering wheel, this requires a special steering wheel puller tool and that you disarm the airbag system before you start the work, to do this disconnect the battery negative cable for 1 hour prior.
