Review AUDI Vw 1.8t Pcv Breather Fittings 3pc Lot 06b 133 989 103 246 De

The **Audi 06B133989C / VW 1.8T PCV Breather Fitting Set (3-Piece, Part Numbers 06B133989C, 103246, and 246)** is a precision-engineered replacement component designed to maintain optimal engine performance and emissions compliance in select Audi and Volkswagen vehicles equipped with the 1.8-liter turbocharged (1.8T) inline-four engine. This critical system component ensures proper ventilation of the crankcase, preventing harmful blow-by gases from accumulating and reducing engine efficiency, while also helping to minimize oil consumption and maintain peak turbocharger longevity. The set consists of three meticulously crafted fittings each tailored to fit seamlessly into the engine bay s PCV (Positive Crankcase Ventilation) system where they connect the crankcase breather line to the intake manifold or turbocharger housing, depending on the vehicle s specific configuration. Crafted from high-quality, durable materials, these fittings are engineered to withstand the demanding conditions of high-performance turbocharged applications, including exposure to heat, vacuum fluctuations, and the corrosive effects of engine oils and fuel residues. Their precise fitment reduces the risk of leaks, which can lead to a loss of vacuum power, increased emissions, or even engine damage over time. Ideal for both original equipment replacement (OEM) and aftermarket upgrades, this breather fitting set is a straightforward yet essential upgrade for mechanics and DIY enthusiasts restoring or maintaining the reliability of their 1.8T-powered Audi or VW vehicles, ensuring compliance with emissions standards and preserving the engine s long-term health.

### **Pros and Cons of Buying Audi/VW 1.8T PCV Breather Fittings (Part Number: 06B 133 989 103, 246)**

#### **Pros:**

1. **Compatibility and Fitment** These fittings are specifically designed for Audi and VW 1.8T engines (including models like the A4, A6, TT, and Golf Mk4/Mk5), ensuring a proper seal and preventing leaks. Using the correct part reduces the risk of oil contamination or vacuum loss.

2. **Prevents Oil Consumption and Carbon Buildup** A faulty PCV (Positive Crankcase Ventilation) system can lead to oil entering the intake, increasing oil consumption and causing carbon deposits on intake valves and pistons. Replacing worn or damaged fittings helps maintain proper crankcase ventilation, reducing these issues.

3. **Improves Engine Efficiency** A well-functioning PCV system ensures proper airflow through the crankcase, reducing pressure buildup and preventing oil leaks into the combustion chamber. This can lead to better engine performance and longevity.

4. **Easy Installation** These fittings are typically a straightforward replacement, requiring minimal tools and time. They often come with gaskets or seals, making the job cleaner and more reliable than using aftermarket alternatives.

5. **OEM Quality** As an original equipment part, it meets Audi/VW s engineering standards, offering durability and reliability comparable to new parts. This reduces the risk of premature failure compared to cheaper, non-OEM alternatives.

6. **Prevents Emissions Issues** A failing PCV system can cause unburned hydrocarbons to escape, leading to check engine lights (P0171, P0174, or P0420 codes). Replacing the fittings helps maintain proper emissions control.

7. **Cost-Effective Long-Term Solution** While the upfront cost may be higher than aftermarket options, the long-term benefits (reduced oil consumption, fewer carbon deposits, and fewer engine issues) often justify the investment.

#### **Cons:**

1. **Higher Upfront Cost** OEM parts are generally more expensive than aftermarket alternatives. Depending on the region, prices can range from **$50 to $120** for the 3-piece set, which may be a concern for budget-conscious buyers.

2. **Potential for Counterfeit Parts** If purchasing online (especially from unverified sellers), there is a risk of receiving fake or low-quality parts. Always buy from reputable dealers or authorized distributors to avoid this.

3. **Limited Availability Outside Dealerships** While these parts are available from online retailers, some independent mechanics or smaller shops may not stock them, requiring special ordering, which can add time and inconvenience.

4. **Mixed Reviews on Durability (If Aftermarket Alternatives Are Chosen)** While the OEM part is reliable, some aftermarket PCV breather kits may fail prematurely or leak. If opting for cheaper alternatives, research and brand reputation are crucial.

5. **May Require Additional Maintenance** If the rest of the PCV system (hoses, valves, or seals) is worn, replacing just the fittings may not fully resolve the issue. A full inspection of the crankcase ventilation system may be needed.

6. **Installation Challenges on Older Models** Some 1.8T engines (particularly in older Audi/VW models) may have tight or awkwardly located PCV breather fittings, making installation slightly more difficult for inexperienced DIYers.

### **Conclusion:**

The **Audi/VW 1.8T PCV Breather Fittings (06B 133 989 103, 246)** are a **highly recommended** replacement part for maintaining engine health, preventing oil consumption, and avoiding emissions-related issues. The **pros significantly outweigh the cons**, especially when considering the long-term benefits of using an OEM-quality component.

**If you re experiencing symptoms like:**

- Excessive oil consumption

- Blue smoke from the exhaust

- Check engine lights (P0171, P0174, P0420)

- Oil leaks around the PCV system

- Carbon buildup in the intake

**then replacing these fittings is a wise investment.** The slight higher cost is justified by the reliability and performance benefits.

**Recommendation:**

- **Buy from an authorized Audi/VW parts dealer or a trusted online retailer** (e.g., RockAuto, Amazon, or local Audi/VW specialists) to ensure authenticity.

- **Inspect the rest of the PCV system** (hoses, valve, and seals) while replacing the fittings if any components are cracked or worn, replace them simultaneously.

- **Follow the manufacturer s installation guidelines** to ensure a proper seal and prevent leaks.

- **Consider professional installation** if you re unsure about working on the engine s ventilation system, as improper fitting can lead to further issues.

**Final Verdict:** **Worth the purchase** for anyone maintaining or restoring a 1.8T Audi/VW engine. The part is crucial for long-term engine protection and efficiency.
