Signs of clogged air filter on Yeti 1.2 TSI

On Škoda Yeti 1.2 TSI The clogged air filter is not as obvious as, for example, on diesel engines. However, there are a few indirect signsthat should alert you:

• 🚗 Deterioration in acceleration dynamicsespecially at speeds above 3,000 rpm. The engine is as if "suffocating" and does not pull.
• ⛽ Increased fuel consumption 0.3-1 l/100 km for no apparent reason (provided that the driving style has not changed).
• 🔊 Unusual sound when the engine is running: the motor can "boil" on idle or with a sharp gassing (whistling indicates air sucking).
• 💨 Black carbon deposits on spark plugs (visual inspection). This is a result of the enriched mixture due to lack of air.

On turbocharged motors, such as 1.2 TSIThe filter is additionally loaded. turbocharger. This may lead to:

• 🔥 Turbine overheating (Especially in the heat or during long periods of time).
• 🛑 Emergency mode activation (Check Engine with an error in boost pressure.
• 💸 Accelerated wear of compressor blades due to abrasive particles.

Step 1. Open the hood and find the filter case.

Air filter housing Yeti 1.2 TSI located to the right of the engine (when you look at the movement) It is a black plastic box with a pipe going to the throttle. There's a lid on the hull. 4 latches (or 2 bolts, depending on the modification).

Step 2. Remove the hull cover.

If you have a slat on your model, just squeeze them one by one (starting from the far side). If you have a screwdriver, you can twist them with a screwdriver or torx. Carefully lift the lid up: there may be dust inside, so it is better to vacuum the space around beforehand.

Step 3. Remove the old filter.

The filter sits tightly in the slots, but without effort. Put it on the side and pull it out. Pay attention to this. condition of the rubber seal perimeter - if it cracked or deformed, the new filter may not fit tightly.

Step 4. We're clearing the case of dust.

Before installing a new filter Be sure to vacuum or wipe the body A clean rag. If there's dirt inside, it will quickly clog a new filter. Check it out, too. crack-pipe This is a common problem on mileage cars.

Step 5. Install a new filter.

Place the filter in the body so that filter-handle (if any) coincided with the direction of air flow (usually indicated on the lid of the case). Make sure the sealing gum fits tightly around the perimeter.

Step 6. We close the lid and fix it.

• 🔄 Installing the filter backwards. Many filters have an arrow indicating the direction of airflow. If you put it wrong, the filter efficiency will decrease. 30–40%.
• 🕳️ Flawed fit of the hull cover. If the latches or bolts are not twisted to the end, a gap is formed between the lid and the body, through which unfiltered air will seep.
• 🧹 Ignoring case cleaning. Dust and debris left in the case, immediately clog the new filter, reducing its resource by 2-3 times.
• 🔧 Using the wrong tool. For example, trying to unscrew bolts with torksom. T20 instead of T25 It can break the slats, which will complicate further maintenance.

One more critical error Buying a filter that is not suitable in size. For example, some analogues (for example, from Filtron) may be 1 to 2 mm of the original, so that the sealing gum will not completely cover the gaps. Always check with catalogs (for example, ETKA or Elcats) before purchasing.

What happens if you drive without an air filter?

Without a filter, not only dust will get into the cylinders, but also small stones, insects, leaves. It'll lead to:

- Scoring on cylinder walls (Repair – capital of the engine from 80,000 rubles).

- Turbine damage (Replacement from 50,000 rubles)

- Throttle and valve contamination (Cleaning from 5,000 rubles).
