The 2011 BMW 328i xDrive offers a well-rounded package of luxury, performance, and all-weather capability. As the all-wheel-drive variant of the final E90 generation, it’s favored by drivers who want German engineering with year-round usability. While it’s one of the more reliable BMWs, no car is without its faults. In this guide, we’ll explore the most common problems specific to the 2011 328i xDrive, including drivetrain, engine, and electrical issues, along with how to fix them.
Is the 2011 BMW 328i xDrive Reliable?
Yes, the 2011 328i xDrive is generally reliable, but it has a few known issues common to the E90 platform and the added complexity of its AWD system. The naturally aspirated N52 engine is solid, and most failures are predictable and preventable with proper maintenance. That said, xDrive models require more attention to drivetrain and suspension components.
Top 2011 BMW 328i xDrive Problems
1. Transfer Case Wear or Failure
As part of the xDrive system, the transfer case manages power distribution between the front and rear wheels. Over time, internal gears and clutches can wear out.
- Symptoms: Binding during turns, jerky acceleration, drivetrain warning light
- Fix: Fluid change (if minor), or full transfer case replacement
- Cost: $250 for fluid service; $1,800–$2,500 for replacement
2. Front Axle Boot and CV Joint Damage
The AWD system increases stress on the front axles. Torn CV boots lead to joint failure if not addressed early.
- Symptoms: Clicking during turns, grease around the wheel well
- Fix: Replace boot or full CV axle
- Cost: $200–$500 per axle
3. Valve Cover Gasket Leak
This issue is common in both RWD and xDrive variants due to heat exposure degrading the gasket material over time.
- Symptoms: Oil smell, smoke from engine bay, visible oil on engine
- Fix: Replace gasket or full valve cover
- Cost: $300–$600
4. Oil Filter Housing Gasket Leak
Oil leaks from the filter housing are notorious in the N52 engine and can drip onto the serpentine belt system.
- Symptoms: Oil near the front passenger side of engine, low oil level light
- Fix: Replace oil filter housing gasket
- Cost: $250–$450
5. Water Pump and Thermostat Failure
The electric water pump is efficient but tends to fail without warning around 80k–100k miles. xDrive models don’t affect this component, but overheating can damage AWD sensors.
- Symptoms: Overheating, high-speed fan, coolant warning
- Fix: Replace both components together
- Cost: $800–$1,200
6. Suspension Bushing Wear (Front Control Arms)
The added weight and torque load on the front end in xDrive models leads to faster wear of bushings and ball joints.
- Symptoms: Clunking over bumps, wandering steering, uneven tire wear
- Fix: Replace control arms or bushings
- Cost: $400–$800
7. Ignition Coil and Spark Plug Failure
This is a common issue across all N52 engines and leads to misfires if ignored.
- Symptoms: Rough idle, check engine light, hesitation under load
- Fix: Replace all six spark plugs and ignition coils
- Cost: $200–$400
8. Crankcase Vent Valve (PCV) Issues
The PCV system can fail, especially in cold climates, causing vacuum leaks or excessive oil consumption.
- Symptoms: Whistling noise, oil consumption, rough idle
- Fix: Replace PCV system or valve cover
- Cost: $300–$500
9. VANOS Solenoid Failure
Dirty or faulty VANOS solenoids affect the variable valve timing system.
- Symptoms: Check engine light, low-end power loss, rough idle
- Fix: Clean or replace solenoids
- Cost: $150–$300
10. Transfer Case Fluid Neglect
This is a maintenance oversight rather than a defect. BMW doesn’t list a service interval, but fluid should be changed every 50k–60k miles.
- Fix: Drain and refill transfer case with BMW-approved fluid
- Cost: $200–$300
Maintenance Tips to Prevent Problems
- Change engine oil every 5,000–7,000 miles
- Replace water pump and thermostat proactively at 90,000 miles
- Service transfer case and differentials every 50,000–60,000 miles
- Inspect front axle boots at every oil change
- Keep battery and IBS system in good condition to avoid electrical gremlins
Repair Cost Summary Table
| Problem | Estimated Repair Cost |
|---|---|
| Transfer case replacement | $1,800–$2,500 |
| Valve cover gasket | $300–$600 |
| Water pump & thermostat | $800–$1,200 |
| Oil filter housing gasket | $250–$450 |
| Ignition coils & spark plugs | $200–$400 |
| CV axle replacement | $200–$500 |
| Suspension bushings | $400–$800 |
How Long Will a 2011 BMW 328i xDrive Last?
With proper care, the 2011 328i xDrive can last well over 200,000 miles. Key factors include keeping the AWD system serviced, staying ahead of oil leaks, and maintaining the cooling system. Owners who ignore transfer case and front axle maintenance are more likely to face costly repairs later.
Final Verdict
The 2011 BMW 328i xDrive is a solid performer with added traction and winter driving confidence, but its AWD system adds complexity. If you’re willing to maintain the transfer case, suspension, and cooling components, this car can be reliable and enjoyable for years. It’s one of the last naturally aspirated BMWs and offers a great balance of luxury, performance, and durability for savvy owners.
Tip: Look for models with documented AWD fluid services, valve cover repairs, and recent water pump replacement to avoid surprise repairs down the road.
