Elements of a combination of devices

Dismantling

The disassembled block of a combination of devices, the front view

1 – the basic plate;
2 – the temperature indicator;
3 – a speedometer;

4 – a digital watch;
5 – an adjusting pin.

On the back party of the disassembled block of a combination of devices we have designated in figures following details

1 – the basic plate with devices;
2 – the block of indicators with the indicator of external temperature;
3 – the panel;

4 – minicheck system;
5 – a regulator of illumination of devices.


The system of minicheck (1) represents own constructive group and is attached behind on the block of a combination of devices (2 three screws with crosswise шлицем.


The system of self-examination (1) also is simply fastened behind on the block of a combination of devices (2). The onboard computer is In the same way attached at corresponding additional equipment.

In our description we adhere most often established on Audi to a combination of devices VDO:

Without assorting the panel of a combination of devices, it is possible to remove following elements from an underside:

  • Indicators (control lamps): lamps накаливания indicators in Audi are soldered strong in in the cartridges and they can be got only as a unit. At purchase of a spare bulb pay attention to colour of a cartridge: are established 1,1-vattnaja, 1,2-vattnaja and 2-vattnaja lamps with variously painted cartridges. For removal it is necessary to turn a cartridge on a turn quarter to the left and to extend.
  • Illumination of scales: look "Indicators".
  • The indicator of temperature of air: to turn out two screws with crosswise шлицем on the indicator block, then two more at the tip.
  • Voltage stabilizer: to turn away one screw with crosswise шлицем, to extend knot from it штекерных connections.
  • Minicheck system (the display block for temperature of a cooling liquid, brakes and pressure of oil): to weaken screws with crosswise шлицем, to extend the group device from штекерных contacts.
  • Self-examination system: as minicheck system.
  • The onboard computer: as minicheck system.
  • The adjusting resistor for illumination of scales: to turn out two шестигранных nuts, to remove adjusting the resistor.
    After dismantling of a combination of devices (for this purpose to remove the adjusting resistor for illumination of scales and system of minicheck or system of self-examination or the onboard computer after that to turn out 11 combined shestigrannyh/zvezdchatyh screws or screws with crosswise шлицем outside on a device underside) there are accessible following elements.
  • Speedometer: to turn out four screws with crosswise шлицем on an underside.
  • Hours with a usual dial: if necessary to remove the indicator of temperature of a cooling liquid (see more low), to remove a case part.
  • Tachometre: to turn out three screws on a device underside.
  • Digital watch: to remove a tachometre. To turn out two small шлицевых the screw on a digital watch and to extend hours forward. Расфиксировать an adjusting pin of a digital watch and cautiously to take out.
  • The indicator of quantity of fuel or the temperature indicator: to turn out on an underside on two шестигранных nuts. To take out a forward part of the case from fixing hooks.
