Review DORMAN Audi Crankcase Vent Valve fits QUATTRO A7 2012–2015

The **Dorman 86622KKXR Crankcase Ventilation Valve** is a precision-engineered replacement part designed specifically for the **2012 2015 Audi A7 Quattro** models equipped with the **3.0L V6 TDI engine**, including the **2013 and 2014 trim years**. This critical component plays a vital role in maintaining optimal engine performance, emissions compliance, and long-term reliability by regulating the flow of crankcase gases through the Positive Crankcase Ventilation (PCV) system. Crafted from high-quality materials, the Dorman valve ensures a secure, leak-free seal while efficiently channeling harmful blow-by gases away from the engine bay, preventing oil dilution and reducing carbon buildup on intake valves a common issue in turbocharged diesel applications. The valve s robust construction, featuring a durable housing and precision-machined internal passages, guarantees smooth operation under the demanding conditions of high-pressure turbocharged diesel engines. Whether addressing a failing original equipment (OEM) valve, a check engine light triggered by PCV system codes (such as P0171 or P0174), or simply performing routine maintenance, this aftermarket replacement offers a direct-fit solution that meets or exceeds OEM specifications. Its compatibility with Audi s advanced turbocharged diesel systems ensures seamless integration with the engine s oil control and emissions control modules, helping to preserve fuel efficiency, reduce exhaust emissions, and extend the lifespan of critical engine components. For mechanics and DIY enthusiasts alike, the Dorman 86622KKXR provides a reliable, cost-effective alternative to OEM parts, backed by Dorman s reputation for quality and durability in the automotive aftermarket.

The **Dorman 86622KKXR** is a crankcase ventilation (PCV) valve designed for the 2012 2015 Audi A7 Quattro (3.0L V6, 3.2L V6, and 4.0L V8 engines). Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros of the Dorman 86622KKXR**

1. **Direct Fitment** Designed specifically for the 2013 2015 Audi A7 Quattro (and some 2012 models), ensuring compatibility without modification. Dorman parts are known for their precision-engineered fit.

2. **Quality Materials** Made from durable plastic and metal components, built to withstand the pressures and temperatures of a modern engine s crankcase ventilation system.

3. **OEM-Level Performance** While not an exact OEM replacement, it meets or exceeds the performance standards of the original Audi part, ensuring proper crankcase pressure regulation and emissions compliance.

4. **Easy Installation** Requires minimal tools and straightforward installation, typically taking less than 30 minutes for a DIYer with basic mechanical skills.

5. **Cost-Effective** Significantly cheaper than an OEM Audi part (often 50 70% less), making it a practical alternative for budget-conscious buyers.

6. **Reliability** Dorman is a trusted aftermarket brand with a strong reputation for longevity in automotive components. Many users report no issues after installation.

7. **Emissions Compliance** Properly functioning PCV valves are critical for passing emissions tests, especially in regions with strict regulations. A faulty valve can trigger check engine lights (P0171, P0174, or P0340-related codes).

8. **Prevents Oil Leaks** A failing PCV valve can cause excessive crankcase pressure, leading to oil leaks at gaskets or seals. Replacing it proactively can prevent more costly repairs.

### **Cons of the Dorman 86622KKXR**

1. **Not an Exact OEM Replica** While functional, it may not match the OEM valve s exact internal design or material composition, which could theoretically affect long-term durability (though this is rare with Dorman).

2. **Potential for Counterfeit Products** Some sellers may offer fake or low-quality Dorman parts. Always purchase from reputable retailers (e.g., RockAuto, Amazon, or authorized Dorman dealers) to avoid counterfeit items.

3. **Limited Lifespan Compared to OEM** OEM parts are often designed for the full lifespan of the vehicle, whereas aftermarket parts may wear out faster under extreme conditions (e.g., high-mileage engines with carbon buildup).

4. **Requires Regular Inspection** Like any PCV valve, this part should be checked periodically (every 30,000 50,000 miles) for clogs or damage, especially if the engine runs poorly or exhibits oil leaks.

5. **Mixed Reviews on Durability** Some users report that the Dorman valve fails prematurely (e.g., within 20,000 40,000 miles), particularly if the engine has high carbon deposits or oil sludge. This is more common in neglected vehicles.

6. **Potential for Incorrect Part Number** Ensure the part number matches your exact engine variant (e.g., 3.0L vs. 3.2L vs. 4.0L). Mixing up the part could lead to improper fitment or performance issues.

7. **No Warranty on Some Retailers** Unlike OEM parts, Dorman s warranty may vary by retailer. Always check the return/warranty policy before purchasing.

### **Conclusion**

The **Dorman 86622KKXR** is a **solid, cost-effective choice** for replacing a faulty PCV valve in a 2012 2015 Audi A7 Quattro. It offers direct fitment, reliability, and significant savings compared to OEM parts. However, it is not a perfect long-term solution it may require replacement sooner than an OEM valve, especially in high-mileage or poorly maintained engines.

The **primary risks** stem from purchasing a counterfeit part or neglecting regular maintenance (e.g., not cleaning the valve or checking for clogs). If your engine has a known history of carbon buildup or oil sludge, consider pairing this replacement with a **PCV valve cleaner** or **engine flush** to extend its lifespan.

---

### **Recommendation**

1. **Buy from a Trusted Source** Purchase the **Dorman 86622KKXR** from a reputable seller (e.g., RockAuto, Amazon, or an authorized auto parts store) to avoid counterfeit parts. Verify the part number matches your engine variant.

2. **Inspect the Engine** Before installing, check for **oil leaks, carbon buildup, or sludge** in the crankcase. If present, address these issues (e.g., with a **PCV valve cleaner** or **engine flush**) to improve the valve s longevity.

3. **Follow Installation Guidelines** Ensure the valve is installed correctly (proper orientation and secure mounting). Refer to the **Audi service manual** or a trusted online guide (e.g., Haynes or Chilton) if unsure.

4. **Monitor Performance** After installation, watch for **check engine lights, oil leaks, or unusual noises** (e.g., hissing from the valve). If issues persist, the valve may need replacement sooner than expected.

5. **Consider Alternatives if Budget Allows** If you prioritize longevity over cost, an **OEM Audi part** (e.g., Audi 06E 109 401) or a **high-quality aftermarket brand** (e.g., **Meguiar s, Mann-Filter, or Bosch**) may be worth the extra investment for long-term reliability.

6. **Set a Reminder for Replacement** PCV valves typically last **50,000 100,000 miles**, but conditions vary. Schedule a **preventative replacement** every **50,000 miles** or if symptoms (e.g., rough idle, oil leaks) arise.

**Final Verdict:** The **Dorman 86622KKXR is a practical and affordable option** for most Audi A7 owners, provided you source it from a reliable seller and maintain the engine properly. For high-mileage or neglected vehicles, pair it with additional maintenance to maximize its lifespan.
