Question about 2005 Audi S4
Sorry for the bad news i have for you, sounds like you dropped pressure to the top end which would mean that the Hydraulic lifters one or more have failed, could be that your intake or exhaust valve may made contact with the pistons at TDC. In any case oil pressure problems are known with that car, we found that one of the ckeck valves in the short block may cause that problem.
Solution would be new Motor at about $15000 with $4000 core unless warranty will cover. make sure you do not have an intake or exhaust system on the car cause they will not cover anything. Other option is to spend about $10000 to do a complete overhaul. First check your oil filter and see if you can see any metal shavings. But according to what you have written i would not longer drive or start the car. Sorry bud, i think your motor is done!!

Sounds like the car is misfiring. possibly a bad coil. If the check engine light is illuminated then there will more than likely be a CEl code for a misfire. it will also indicate which cylinder or cylinders are misfiring. I'm not sure but I believe I've heard someone say not too drive the car to far or hard if the check engine light is flashing.
