I’ll show you how to clean or replace the air filter in a Volkswagen Golf 1.4 TSI engine. The filter does not usually need replacing very often. The air intake and the filter on this car is here on the front left the filter is inside the box and there is a short intake duct which terminates directly behind mini grill at the front of the car which functions as a cold air intake. Basically, you can take this plastic cap off the intake it just pulled straight off and up and have a look inside it and under round ducting. Screw out the four screws of the filter, then it takes out.
You need to take plastic retaining bracket first and unscrew it and again the screw can be left in place, then you can remove the filter.
The filter’s cylindrical design where air is drawn from the outside passes through the filter and goes into the engine intake from the inside. So you can check the condition of the filter on the outside and again just sort of visually inspect how dirty it is.
You might want to run a vacuum cleaner over a surface to remove any obvious contaminants and if it’s really dark and obviously dirty then it would want replacing. But air sources are often replaced unnecessarily in normal clean road usage. If you do want to replace it I suggest getting another paper filter like the Volkswagen version from a quality OEM on manufacturer
Once you’ve cleaned your old filter or gotten a new one replacement, it’s just the reverse of removal, you make sure the plastic brackets at the intake side are lined up correctly. Put it back in the retaining bracket will seal the outside of the filter from the inside. Put the bracket back in place it will need a little gentle force to go in and then the sorcerer will become fixed in place. Screw back up just tighten it up firmly and check that everything is solid. And the airbox lid can go back on. I need to make sure that it’s aligned correctly, you can check that the mating edges are correctly lined up.
