Review BMW Used Series A/c Condenser And Ps Oil Cooler Oem fits E39 1997–2003

The **BMW E39 A/C Condenser Oil Cooler (Part Number: 17111740787, Compatible with Models from 1997 2003)** is a critical component of the E39 series climate control system, designed to enhance efficiency and longevity by integrating cooling functions for both the air conditioning and engine oil circuits. This high-performance part is engineered to dissipate heat generated during operation, preventing overheating in the oil cooler while simultaneously maintaining optimal performance of the A/C condenser. Crafted from durable materials, including high-grade aluminum and reinforced plastic housing, the oil cooler ensures robust thermal management, reducing the risk of system failure in demanding driving conditions, such as prolonged highway travel or stop-and-go traffic where engine temperatures fluctuate. Its compact yet efficient design allows for seamless integration into the E39 s under-hood architecture, where it sits adjacent to the radiator and A/C condenser, forming part of the vehicle s cooling matrix. This dual-function component is particularly vital for BMW s E39 models, which often feature high-performance engines that generate significant heat, making efficient oil and refrigerant cooling essential for both passenger comfort and engine protection. Whether installed in a classic 5-Series sedan, wagon, or touring model, this oil cooler ensures that the A/C system operates at peak efficiency while mitigating the risk of oil degradation, thus extending the lifespan of the engine and cooling components alike. For enthusiasts and owners seeking to restore or upgrade their E39 s climate control system, this genuine BMW part represents a reliable, factory-specified solution that balances performance, durability, and compatibility.

### **Pros and Cons of Buying a Used BMW E39 (1997 2003) with a/C Condenser/Oil Cooler (Part #17111740787)**

1. **Common and Widely Available Parts** The E39 is one of BMW s most popular models, meaning replacement parts, including the A/C condenser/oil cooler, are easy to find. Aftermarket and OEM options are abundant, reducing long wait times and high costs.

2. **Proven Reliability (When Maintained)** With proper upkeep, the E39 s M54 (1999 ) and M52 (pre-1999) engines are known for durability. Many owners report these engines lasting well beyond 200,000 miles with regular maintenance.

3. **Strong Aftermarket Support** Tuning, modifications, and performance upgrades are widely available. The E39 community is active, offering forums, rebuild kits, and DIY guides for common issues like oil leaks, suspension wear, and electrical gremlins.

4. **Good Driving Dynamics** The E39 s chassis is praised for its balance, handling, and comfort. The M54 engine (especially in the 328i/330i) provides a strong yet smooth power delivery, making it enjoyable for both daily driving and spirited cruising.

5. **Resale Value (Compared to Peers)** While not as high as newer BMWs, the E39 retains decent resale value, especially in well-maintained or restored condition. Classic BMWs with strong demand (like the E39) often hold their value better than generic German sedans.

6. **Potential for Restoration** If the car is in rough shape, a well-executed restoration can yield a highly desirable project vehicle. Many enthusiasts enjoy the process of bringing an E39 back to showroom condition.

7. **Affordable Entry Point** Used E39s are generally cheaper than newer BMWs, making them a practical choice for buyers who want a premium driving experience without the high cost of a modern model.

1. **Common Electrical Issues** The E39 is notorious for electrical problems, including faulty sensors, wiring harness failures, and computer glitches. The A/C system itself may have issues with relays, compressors, or refrigerant leaks, which can be costly to diagnose and repair.

2. **Oil Leaks (Especially on M54 Engines)** The M54 engine (1999 ) is prone to oil leaks from the valve cover gasket, oil filter housing gasket, and oil pan gasket. These leaks can lead to low oil levels, engine damage, and costly repairs if ignored.

3. **Suspension Wear** The E39 s suspension components (shocks, struts, bushings, and ball joints) wear out relatively quickly, especially on high-mileage examples. Replacing these parts can add up in maintenance costs.

4. **Transmission Problems (Especially in Early Models)** Pre-1999 E39s with the ZF 5HP19 transmission can develop rough shifting or failure over time. Later models (with the Getrag 260/5) are more reliable but still require attention.

5. **A/C System Reliability** The A/C condenser/oil cooler (part #17111740787) is a critical component, and if it s failing, it can lead to compressor damage, refrigerant leaks, or complete A/C failure. Replacing it requires proper sealing to avoid oil leaks into the A/C system.

6. **Rust (Especially in Snow Belt Regions)** Older E39s from areas with harsh winters may suffer from rust in the wheel wells, rocker panels, and undercarriage. Rust can weaken structural components and lead to costly repairs if not addressed early.

7. **Maintenance Costs Can Add Up** While parts are cheap, labor costs for BMWs are often high due to specialized tools and trained technicians. Regular maintenance (timing belt, spark plugs, fuel injectors, etc.) is essential to avoid major failures.

8. **Depreciation** Like most cars, the E39 loses value over time. If you plan to keep it long-term, you ll need to budget for eventual replacement parts or a new car down the road.

- **Blown head gaskets** (common in M52 engines with overheating).

- **Failed turbochargers** (on turbocharged models like the M52TU).

- **Corroded fuel injectors** (leading to misfires and poor performance).

- **Worn-out timing chains** (M54 engines are more forgiving, but still require attention).

10. **Insurance Costs** Older BMWs can be expensive to insure, especially if you carry comprehensive coverage. Some insurers may also charge higher premiums due to the car s reputation for mechanical issues.

Buying a used BMW E39 (1997 2003) with a failing A/C condenser/oil cooler can be a great investment if you re prepared for potential maintenance challenges. The car offers a fantastic driving experience, strong aftermarket support, and affordable parts **but only if you re willing to put in the work (or budget for repairs)**.

If you re buying one primarily for the A/C condenser/oil cooler replacement, ensure the rest of the car is in decent shape. A well-maintained E39 can be a rewarding daily driver or a fun project car, but a neglected one can become a money pit.

---

- Engine condition (oil leaks, compression, timing chain wear).

- Transmission fluid and shift smoothness.

- Suspension and steering components.

- Electrical system (check all sensors, fuses, and wiring).

- A/C system (test compressor operation, check for refrigerant leaks).

2. **Budget for Repairs** If buying used, expect to spend **$1,500 $3,000 ** on immediate repairs (oil leaks, suspension, electrical fixes). Factor in long-term maintenance like timing belt replacement (every 60K 100K miles) and fuel system cleaning.

3. **Consider a Restored Example** If you want a hassle-free E39, look for one that has already been restored or well-maintained. A "project car" can be fun but requires time and money.

4. **Prioritize the A/C System** If the condenser/oil cooler is failing, ensure the compressor and refrigerant levels are checked. A failing A/C system can lead to compressor damage if ignored.

5. **Buy from a Reputable Seller** Dealerships, private sellers with full service records, or trusted BMW clubs are better choices than random listings. Avoid "too good to be true" deals common issues like oil leaks or electrical gremlins are often hidden until after purchase.

6. **Decide on Your Goals**

- **Daily Driver?** Choose a low-mileage example with full service history.

- **Project Car?** Look for a cheap but structurally sound E39 and enjoy the rebuild.

- **Classic/Collectible?** Focus on well-preserved examples with originality (or restored to high standards).

**Final Verdict:** The BMW E39 is a fantastic car for the right buyer one who understands its quirks and is willing to invest time or money in keeping it running. If you re prepared for potential repairs and enjoy the driving experience, it s a great choice. If you want a plug-and-play vehicle with minimal hassle, consider a newer BMW or a different classic model with fewer known issues.
