Violations in work and self-diagnostics

The electronic control unit system of injection of Motronic can distinguish and remember the defects arising in operating time of the engine. The distinguished defects are remembered in a computer memory. If you assume defect existence in a control system of ignition/injection, you can make computer poll only in Audi workshop. But in addition you can use our councils on assistance at malfunctions where the numerous possible defects revealed by self-diagnostics are given.

 Council: The control unit system ignition/injection of Motronic can distinguish 46 types of malfunctions in electric knots of system of ignition/injection and keep them in memory of the computer. Sporadic arising defects are erased from memory of the computer after 50 starts of the cold engine in case they do not arise repeatedly.
