How often does Audi A4L throttle have to be cleaned?

Audi A4L throttle needs to be cleaned once when it travels about 20,000-30,000 kilometers. If it is not too dirty, you can clean the throttle directly with cleaning agent without disassembling the throttle. However, it can be cleaner to remove the throttle valve for cleaning. The specific cleaning steps are as follows:

1. Find the position of the throttle valve, which is located behind the air inlet and connected to the air filter;

2. Remove the hose connecting the throttle and the air filter first, and then remove the assembly of the air filter;

3. Then remove the throttle cable, unscrew the fixing bolt and remove the throttle;

4. Use special cleaning agent or carburetor cleaning agent, spray it on the throttle, wait for the organic solvent to dissolve the carbon deposit, and dry it for 1-2 minutes.

In addition to the above methods, you can also use the cleaning method without disassembling the throttle valve, and directly spray the cleaning agent into the throttle valve when the engine is running. The practice of many 4S shops and maintenance points is to slam on the accelerator while spraying cleaning agent into the accelerator. At this time, the car will emit white smoke, mainly because the cleaned stains are strongly ignited by the suction cylinder and then discharged. This kind of cleaning method is relatively more harmful to the vehicle, and it is generally better to disassemble and clean it, which will not cause too much damage to the vehicle.
