The flashing is telling you that the engine is mis-firing, the dealer will run a test to determine the cylinder that is mis-firing, chances are it is something simple

I had the same problem with my wife's 2006 passat turbo. We lost 2.5 quarts in 3000 miles and the warning light came on. They put us on a 1000 mile oil test and I lost 1.8 more quarts of oil. They finally agreed to replace the rings. Service tech told me that the factory rings are defective, they begin to lead after about 25,000.

The oil in the spark plug may cause the car to run sluggish. The oil may prevent the spark plug from firing correctly or cause you to burn oil. You may want to replace the oil seals around the spark plug holes by removing the valve cover and you should be able to change the oil seals underneath the cover. While at it check the engine for loose wire connections and loose vacuum hoses.

A flashing check engine light is a critical indicator. That usually means that something went wrong that will damage the emission control system... and that is usually an ignition issue. First off, the OEM plug your car calls for is an NGK irridium... NOT BOSCH and not anything with more than 1 prong. Those NGKs are like 2 bucks and they are the proper plug. Make sure you have these plugs and make sure they are gapped to .028. Next, my suggestion is put all the new stuff on again. Drive it to autozone and have them delete all the codes. Drive it around until the check engine light comes on again, then immediately go back and read the codes. The ECU is smart enough to know which cylinder is misfiring. On these cars, I think they have three banks of two... meaning one "coil" inside the coil pack operates two of the cylinders. So if you get multiple misfires, it's the coil. If you get one misfire it's probably an individual plug wire or plug. Good luck.
