Question about Cars & Trucks
You need to have the car scanned. It is a free service at Autozone,Advance, or Oreilys autoparts. Then the clerk can tell you some of the possible parts you need. If you get the Code numbers, we can tell you what the onboard computer is telling you.
Be careful if it is a Code 401, for that engine the scan can be wrong. If 401 comes up, it can be a clogged EGR port in the Intake manifold.

SOURCE: check engine light blinks
My suggestion is to get the fault codes stored in the car's ecu read by a VW approved garage. That will tell them what "was" wrong. Once a fault has occurred the check engine light will probably stay on until the warning has been cancelled using VW software.
As for the grade of gas used in the car, the users manual will tell you that - it might also be written inside the filler cap.
I wouldn't recommend further use of "engine cleaner" - it might do more harm than good.
Go get the codes read and then you'll know for sure.
Hope this helps. D

you have to get a reading of the on board diagnostic system, Autozone read it for free . then they will print a code for you that will show which part is causing the problem (oxygen sensor or the catalytic converter )

SOURCE: Blinking Check Engine light
This is typically a sign of a "detrimental misfire". A blinking check engine light means DON'T DRIVE ME! You may want to have your coil pack checked, plugs replaced or gapped properly, or wires replaced. Would also have to do with the camshaft sensor causing your timing to be off.

#4 Miss-fire. All the things you are saying make a lot of sense. When the light is blinking the cylinder is actualy misfiring, & the smell you are smelling is the fuel that is not burning in the engine burning in the exahst. This can cause a lot of damage to the exausht if it is not repaired..
There is still a couple of things that need to be checked, first he needs to check to see if it is possibly a fuel injector that is sticking. He can do this easily by moving the #4 injector to another cylinder & run the car. When it starts missfiring he will need to see if it is still #4 or if it is the cylinder that he moved the injector to. if it is the new cylinder it is obviously the injector, if it is still #4 he will need to look into the possibility of the EGR valve sticking open or some other issue to do with valve timing or low compression.
I hope this helps

You need to have it scanned for codes. The flashing overdrive light means it has trouble codes that pertain to the transmission.
