Ok, so that sounds like a conductor plate issue. Does the snap on read live data? If so, check the speeds of the sensors as you drive, y3/6n2 is usually 0 and y3/6n3 should be making good rpms, y3/6n2 should show rpms when you idle - or reverse(if I remember well) - within the range of the engine rpm depending on your current gear, If you find some extremely high and impossible rpms there, then that could certainly point you to the conductor plate.
Start with changing the oil and filter and see how that goes, you can always neatly remove it to very clean containers and reuse if you finally need to change the conductor plate; it should still be fine..
