I HAVE THE SAME PROBLEM... what is the problem ?I have an Audi A5 2.0 Model 2010
The car slows down + EPC light on + Check engine light blinking + white smoke.
They cleaned the injectors and changed on coil; the car worked normally.
It did again, cleaned the injectors again. After one month, had same problem. On top of top, the car is not starting smoothly. It went off before doing again same error (epc+check engine light+ white smoke)
