Plug connections

Long time in statistics of malfunctions of General automobile club of Germany (ADAC) the weakened plug connections were noted as one of the most frequent reasons of malfunctions – and almost at all cars.

Now Audi put it an end in literal sense of this word: practically all shtekerny connections are supplied with additional mechanical protection.

This protection needs to be overcome before a plug detachment. Further the most often found types of protection of plugs are listed.

  • Plugs of system of injection are protected by a wire bracket which needs to be wrung out down.
  • Many multicontact plugs are supplied on each side with protective clamps on which it is necessary to press before a plug detachment.
  • For example, on the block of a combination of devices the multicontact plugs protected by a plug-in bracket are located.
