Review REIN 72-51 Oil Separator To Intake Crankcase Breather Hose Audi Ub fits Q3 2015–2018

The **REIN C757 72-51 Oil Separator Intake Crankcase Breather Hose** is a meticulously engineered replacement part designed specifically for the **2015 2018 Audi Q3 (8U) with the 1.4L or 1.8L TFSI engine (UB platform)**, ensuring optimal performance, longevity, and emissions compliance. This high-quality, direct-fit hose serves as a critical component of the vehicle s **crankcase ventilation system**, effectively separating oil vapors from the intake air to prevent engine contamination while maintaining proper pressure balance within the crankcase. Crafted from durable, heat-resistant **EPDM rubber**, this hose is engineered to withstand the demanding conditions of high-performance driving, extreme temperatures, and prolonged exposure to engine oils and fuel residues, minimizing the risk of cracking, hardening, or premature failure. The **reinforced construction** ensures a secure, leak-free connection to the oil separator and intake manifold, reducing the likelihood of vacuum leaks that could compromise engine efficiency or trigger the check engine light. Beyond its functional reliability, this part adheres to strict **OEM specifications**, guaranteeing a seamless fit with the factory-installed components while delivering the same level of precision and performance as the original equipment. Whether addressing a worn-out hose, a noticeable oil leak, or a persistent check engine code related to the crankcase ventilation system, the REIN C757 72-51 is a trusted solution that restores proper airflow dynamics, enhances engine protection, and contributes to smoother operation making it an indispensable upgrade for Audi Q3 owners seeking both performance and longevity.

### Pros and Cons of buying a Rein C757 72-51 Oil Separator Intake Crankcase Breather Hose for a 2015-2018 Audi Q3

#### **Pros:**

1. **Direct Fitment** This part is specifically designed for the 2015-2018 Audi Q3, ensuring compatibility without the need for modifications. It replaces the original crankcase breather and oil separator intake hose, reducing the risk of installation errors.

2. **Improved Engine Breathing** A properly functioning crankcase breather system helps regulate pressure in the engine bay, reducing oil leaks and preventing moisture buildup. Rein s design may offer better airflow efficiency compared to the OEM part, especially if the original component was worn or clogged.

3. **Durability** Rein is a reputable aftermarket brand known for producing high-quality, long-lasting automotive parts. The reinforced construction of this hose is likely to withstand engine heat and vibrations better than the stock part, which may degrade over time.

4. **Prevents Oil Contamination** The oil separator function helps filter out oil vapors and particles, reducing the risk of oil entering the intake system. This can improve engine performance and longevity by keeping the air intake cleaner.

5. **Easy Installation** Rein parts are often designed with straightforward installation in mind. The C757 hose should be relatively simple to replace, requiring basic tools and minimal disassembly, making it a DIY-friendly upgrade.

6. **Cost-Effective Alternative** While not always cheaper than OEM parts, Rein s pricing is typically competitive, offering a balance between quality and affordability compared to purchasing an original Audi part.

#### **Cons:**

1. **Potential Quality Variations** Even from a trusted brand like Rein, there is a slight risk of receiving a subpar or counterfeit part, especially if purchased from an unverified seller. Always buy from authorized dealers or reputable online retailers to mitigate this risk.

2. **Limited Brand Loyalty** Audi owners often prefer OEM or Audi-approved parts for warranty and long-term reliability reasons. Using an aftermarket part like this may void certain warranty coverage if the issue stems from the breather system.

3. **Compatibility Concerns** While the part is advertised for direct fitment, slight variations in engine bay layouts or minor updates between model years (e.g., 2015 vs. 2018) could require minor adjustments during installation. Always verify the exact fitment for your specific trim.

4. **No Warranty on Original Equipment** Unlike OEM parts, Rein s warranty may not cover the same range of issues or offer the same level of customer support. If the part fails prematurely, replacement costs may fall on the buyer.

5. **Installation Challenges** Although generally straightforward, some users may encounter difficulties if they lack mechanical experience. Improper installation such as incorrect sealing or routing could lead to leaks or reduced effectiveness.

6. **Mixed Reviews on Longevity** While Rein parts are generally durable, individual experiences vary. Some users report that the hose may wear out faster than expected under extreme conditions (e.g., high-mileage engines, aggressive driving, or extreme climates).

### **Conclusion:**

The Rein C757 72-51 oil separator intake crankcase breather hose is a solid aftermarket option for the 2015-2018 Audi Q3, offering improved durability, better engine breathing, and ease of installation. It is a practical choice for owners looking to upgrade or replace a worn-out OEM part without breaking the bank. However, it is not without drawbacks, particularly regarding warranty coverage, potential quality inconsistencies, and the risk of installation errors if not handled carefully.

For most owners, the benefits outweigh the cons, especially if the original part is failing or showing signs of wear. If you prioritize long-term reliability and warranty protection, an OEM or Audi-approved replacement might be preferable, though it will likely cost more.
