Start of the engine with the discharged accumulator

If the engine is not started because of the discharged accumulator, it is not dangerous. Otherwise the situation is at malfunction in system of ignition: in this case not burned down particles of working mix can ignite and lift in addition temperature in the catalyst to dangerous level.

Start of the engine by means of an auxiliary wire


  1. The car with the charged accumulator put at such distance that it was possible to lay an auxiliary wire on the right in the motive compartment Audi.
  2. Check, whether all consumers of current are disconnected in your disconnected car.
  3. Connect a wire plus poles of both accumulators.
  4. Connect other auxiliary wire in the beginning to a minus pole of the charged someone else's accumulator, and then to uninsulated weight (for example, directly to the engine) in a motive compartment of the disconnected car.
  5. Start the engine of the auxiliary car on the raised turns in order that the generator intensively gave tension.
  6. If the engine is not started at once, let's a starter cool down a little. Again start the auxiliary engine therefore the discharged accumulator will be charged already a little.
  7. At a detachment of an auxiliary wire for start-up of the engine remove wires from the minus plug of the charged someone else's accumulator in the beginning.

Start of the engine from "pusher"

The easiest way it is possible to start the engine if to push the car under a bias. If the bias is not present, muscular force will help, but two assistants to push Audi are necessary:


  1. Include ignition.
  2. Put the 1st transfer. On higher transfers the generator is turned too slowly for intensive giving of current.
  3. Press a coupling pedal, push the car until it sweeps.
  4. Quickly include coupling. The engine is sharply turned and has to be started.
  5. At once press a pedal of coupling and give gas.

Towage of the car

For towage find the skilled assistant in this question in order that because of nonprofessional approach not to do still bigger harm. Also remember the following: at the idle engine does not work also servoupravleny and the brake amplifier.


  1. Include ignition, put the 2nd transfer and wring out a coupling pedal.
  2. The towing car has to begin the movement slowly.
  3. Approximately at 15 km/h slowly include coupling, thus put the right hand on the emergency brake.
  4. If the engine was started, press a pedal of coupling and give gas.
  5. Softly pull the emergency brake not to drive in the forward car.
  6. The driver of the towed car gives a sound signal.
  7. Switch off transfer, release a coupling pedal.
  8. Slow down by means of the emergency brake together with the towing car.
