Elements outside the cabin, set of elements "3". 1. Coolant circulation pump "V50" (water pump "V36"). "V50" "V36" is installed only on vehicles with the additional equipment "autonomous heater". On vehicles with a 6-cyl. TFSI engine, depending on the vehicle equipment, "V50-V36" can be installed in this place. In these vehicles with the optional "autonomous heater", the circulation pump takes over the "V55" function "V50" ("V36"). Depending on the design of the climate control and display panel, the Climatronic control unit "J255" can be designated as the coolant circulation pump "V50" in the guided troubleshooting, as well as the water pump "V36"; 2. Coolant circulation pump "V50" (water pump "V36"). "V50" ("V36") is installed only on cars from the 2010 model year with the additional equipment "start/stop system", but without the additional equipment "autonomous heater". On cars with the "start/stop system" and the additional equipment "autonomous heater" "G50" ("V36") is not installed. In these cars, the circulation pump takes over the "V55" function "V50" ("V36"). Depending on the design of the climate control and display panel, the Climatronic control unit "J255" can be designated as the coolant circulation pump "V50" in the guided troubleshooting, as well as the water pump "V36".
Water circulation pump "V50" (water pump "V36") on a car with a 4-cylinder engine
Instruction. Depending on the design of the climate control and display panel, the Climatronic control unit "J255" can be designated as the coolant circulation pump "V50" in the guided troubleshooting, as well as the water pump "V36". On vehicles with a 4-cyl. engine and additional equipment "start/stop system", but without additional equipment "autonomous heater" is installed ("V50") "V36". Management "V50" ("V36") depends on the kit and date of manufacture of the vehicle. For vehicles with a 4-cyl. engine and additional equipment "start/stop system", but without additional equipment "autonomous heater" coolant circulation pump "V50" ("V36") "A" is installed, for example, in the area between the engine and the front wall of the water plenum chamber. This figure shows the location for an Audi A4 with a 4-cyl. TFSI engine of the 2010 model year. Depending on the engine, vehicle type and production period, the coolant circulation pump "V50" (water pump "V36") "A" may also be installed in a different location (for example, in a water drainage box). When working "V50" ("V36") The coolant is sucked in through the coolant supply hose "B" (from the engine through the climate control heat exchanger, settings and coolant shut-off valve "D") and through the coolant supply hose "C" is directed back into the engine (take into account the direction of the "arrow").
"V50" ("V36") with the ignition on, depending on the coolant temperature and the settings on the climate control and display unit, the settings, the Gimatronic "J255" control unit are controlled directly from this unit. Depending on the vehicle version "V50" ("V36") receives control signals not only when the "stop function" is active, but also when the engine is running, for example, when the temperature is pre-selected to "Heat" on the control and display panel, the Climatronic control unit "J255" (indication "HI" on the display of the control and display panel for climate control, settings and Multi Media Interface). The coolant circulation pump "V50" is then controlled to support the engine coolant pump. On vehicles with a "start-stop system" "V50" ("V36") and the coolant shut-off valve for Climatronic "N422" is controlled directly from the climate control panel, installation, Climatronic control unit "J255". If faults persist on these units in the climate control panel, installation, Climatronic control unit "J255", the design, coding and adaptation of "J255" must be observed. On vehicles with the optional "autonomous heater", the coolant shut-off valve for Climatronic "N422" is not installed and "V50" ("V36"). In such cars, this function is performed by the components of the independent heater (the coolant shut-off valve for the heater "N₂79" and the circulation pump "V55").
Water circulation pump "V50" (water pump "V36") for cars with 6-cyl. petrol engine
Instructions. Depending on the design of the climate control and display panel, the Climatronic control unit "J255" can be designated as the coolant circulation pump "V50" in the guided troubleshooting, as well as the water pump "V36".
For vehicles with 6-cyl. FSI engine (in the 6-cyl. TFSI engine is currently not provided) and in other engines with additional equipment (e.g. in cars with "start/stop system"), but without additional equipment "autonomous heater" "V50" recirculation pump OZHL/36- is installed. Control "V50" ("V36") depends on the vehicle's kit and production date. For vehicles with a 6-cyl. FSI engine without the optional "autonomous heater", a "V50" ("V36") "A", e.g. in the area of the engine and the right side member under the right headlight. This illustration shows the arrangement for the Audi A5 Coupe with a 6-cyl. FSI engine; on the Audi Q5 there are deviations from this arrangement of parts/assemblies. When running "V50" ("V36") The coolant is sucked in through the coolant supply hose "B" (from the engine) and is directed through the coolant supply hose "C" to the heat exchanger in the air conditioner (take into account the "arrows" for the direction of movement).
Coolant circulation pump "V50" ("V36") depending on the production date, it is controlled via the circulation pump relay "J160" (via the same output as the coolant shut-off valve of the Climatronic unit "N422") or directly from the climate control and display unit, the Climatronic control unit "J255", which is gradually installed from the model year 2009. On cars with the circulation pump relay "J160" (eg on a 2008 model year vehicle) management is carried out "V50" ("V36") with the ignition on, if the Climatronic coolant shut-off valve "N422" is not controlled correctly (e.g., with the "heat" temperature mode on the climate control and display panel, installation, Climatronic unit "J255"). On vehicles without the "J160" circulation pump relay (gradual introduction from model year 2009) coolant circulation pump "V50" ("V36") with the ignition on, depending on the coolant temperature and the settings on the climate control and display unit, the settings, the Climatronic control unit "J255" was controlled directly from this unit. Depending on the vehicle version "V50" ("V36") receives control signals not only when the "stop function" is active (gradual introduction as an additional kit since 2010 model year), but also when the engine is running, for example, when the temperature is pre-selected to "Heat" on the control and display panel, Climatronic control unit "J255" (indication "HI" on the display of the control and display panel for climate control, settings and Multi Media Interface). The coolant circulation pump "V50" is then controlled to support the engine coolant pump. On vehicles on which the coolant circulation pump "V50-V36" and the coolant shut-off valve for Climatronic "N422" are controlled directly from the control and display panel for climate control, settings, Climatronic control unit "J255", faults are stored on these units in the control and display panel for climate control, settings, Climatronic control unit "J255". Therefore, the design, coding and adaptation of "J255" must be taken into account. On vehicles with the optional "auxiliary heater", the coolant shut-off valve for Climatronic "N422" is not installed and "V50" ("V36"). In such cars, this function is performed by the components of the independent heater (the coolant shut-off valve for the heater "N₂79" and the circulation pump "V55").
