Driving down road and my Audi stopped running. Did not hear any noise or anything unusual. Compression check is none in cylinder #1, 50psi in #2, none in cylinder #3, around 50psi in #4. Seems to have a little oil on #4 spark plug. Timing belt is still on and in one piece. no codes, but check engine light on. Do not hear any unusual noise when engine turns over. Fuel pressure is at 60psi at the engine. Maintenance has not been done when recommended due to youth driver not taking care of the car. Need suggestions please.

 

Check the ignition coils check engine control fuses an lets not hope its the cam tensioner... Happened to me an it was fuse #2sw9 had blown an 2 ignition coils were blown....
