Question about Cars & Trucks
You have bad valve seals. Blue smoke is oil burning. White is water/coolant, black is to much fuel. If the car runs good after the smoke, then it isn't a head job. I recommend you get a manual. It is exitensive work,, but follow the manual and you can do it.

Its not likley to be an injector fault.the air mass meter is far more common.if you unplug it it defaults to a average value and should improve the way it runs if that is the problem.

The EPC light means the car is running in "Limp Mode". I had the same thing happen to my car (2001.5 Passat GLS) and i chased the problem for three months.... I would drive and begin to get on the interstate only to have complete loss of power and inability to accelerate. Id pull over, turn off the car then crank it right back up and it was fine. But it came back again randomly. I would suggest pulling codes with a scanner. If you do not have one most local auto parts stores will scan them for free. Mine turned out to be a sensor that is right on top of the engine in the front.... If I'm not mistaken it's the engine speed sensor, also called crank sensor or impulse sensor. You may also want to do a throttle body cleaning.... That would be beneficial no matter what.use extreme care when doing any TB stuff, though, as it's very sensitive. I doubt you want to be forced to get a new one for ~650$. I'd also suggest getting the Bentley Manual for the car as its VERY handy!

Does the smoke occur all the time? If it is present just after start up and then goes away, it could be no problem at all. There is always some condensation in the exhaust at start up. It is more noticeable in cold weather.
However, if it is there constantly, and you are losing coolant, it could mean there is a headgasket problem. Watch your coolant level and watch your temperature gauge. If the coolant starts disappearing, and the car starts overheating, stop it immediately and get it to an auto repair shop. Driving a car with a bad headgasket can cause major engine damage.
