Infringements in work and self-diagnostics

The block of management MPI/MPFI can distinguish about 30 defects in electric knots of system of ignition/injection and keep in a computer memory. Distinction between constant defects and спорадически (sometimes) arising failures in work thus becomes. The information about спорадически arising defects is erased after 50 starts of the engine if they did not arise repeatedly.
In a workshop the computer with the information on malfunctions is interrogated by means of the device for reading V.A.G 1551 (Regular servicing see the head). The fan does not have possibility for such interrogation, therefore at prospective defect in ignition/injection system it is necessary to charge for a workshop to consider the information on malfunctions in a memory.

In addition you can take advantage of section the Help at malfunctions in the end of the head in whom the set of the possible defects revealed by means of self-diagnostics is resulted.

For form's sake after repair in a workshop it is necessary to erase the information on malfunctions by means of the device for reading.
