The steps for removing and installing the evaporator box of an Audi A6L are as follows: 1. After removing the glove box on the passenger side, disconnect the water pipe leading to the heater core. 2. Remove the glove box on the driver's side and use a 4mm hex wrench to remove the screws on the evaporator box pipe. 3. Extract the evaporator box and reinstall it in the reverse order. Taking the 2020 Audi A6L as an example, it belongs to the mid-to-large-sized car category with body dimensions of: length 5038mm, width 1886mm, height 1475mm, wheelbase 3024mm, and a fuel tank capacity of 73 liters. The 2020 Audi A6L features a five-link independent suspension at the front and rear, and is equipped with a 2.0L turbocharged engine, delivering a maximum horsepower of 190PS, maximum power of 140kW, maximum torque of 320Nm, paired with a 7-speed dual-clutch transmission.
As someone who frequently handles Audi repairs, I remember that removing and installing the evaporator for an Audi A6L requires careful steps. First, ensure safety: park the car on a level surface and disconnect the negative terminal of the battery to prevent accidental short circuits. Next, evacuate the refrigerant—this is a professional task, so don't attempt it without the proper equipment. Have a certified shop use a recovery machine to handle the R134a. Only then can you proceed to remove the dashboard: use a screwdriver to take off the dashboard cover, the air conditioning control module, and the glove box, then disconnect the wiring harness and ducts. To remove the evaporator, first unscrew the mounting bolts and slowly pull out the old unit—avoid forcing it to prevent damage. When installing the new evaporator, reverse the steps, ensuring the seals are properly seated. Finally, recharge the refrigerant and test-run the system. The entire process is time-consuming, and tools like a torque wrench are essential. Regular cleaning of the air conditioning system is recommended to prevent odors or blockages that could lead to further repairs.
