Carburetor 2-EE (Audi 80 B3, 1986-1991 / Power unit / Fuel system (gasoline))

The 2-EE carburetor is an electronically controlled carburetor with a falling flow and sequential inclusion of mixing chambers. There are no previous control devices for enriching the mixture during start-up, warm-up and acceleration, as well as an idle shut-off valve. The functions of the missing control devices are performed by 2 control elements, the pre-throttle regulator and the throttle valve regulator. The regulators are controlled by a microprocessor-based electronic control device, which is located between the transverse wall at the front right and the air duct.

To remove the appliance, remove the upholstery before "glove box", press the collet against the transverse wall and pull the control unit downwards.
