The best ideea is to scan your Engine Control Unit with a VAG-COM, Bosch KTS, ... diagnosis tool. If you have one of these dedicated scan tools you will find definitely the engine fault code-"P...." and the clear description of the error. Also you can try to erase this error (or these errors) from the Engine Control Unit memory. If errors are "sporadic" type you certain have permission to erase them, also for some kinds of "static" errors. Because your Engine "MIL" - Malfunction Indicator Lamp keeps coming "ON" and "OFF" you have a big good hand to clean errors from Engine Management System memory. If you don't have any diagnosis tool, you can also try something else. For check up if the engine have a proper turn, you can successively disconnect each spark plug coil from the engine wiring system, engine idle, car stationary. When you operating this you must be free of chassis ground (battery ground)!!! When you disconnect a spark plug coil and the engine speed (rpm) drops, that means this coil works properly. When one coil disconnected and engine speed (rpm) still remain unaltered, this coil (or spark plug) is out of order. First you can change only the spark plug and check up again. If no changes the coil is defective and must be replaced! My recommendation is first to change all spark plugs on the engine, and after that check up coils. Please Rate my Response! Thanks!

When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.
