Turbocharger GT1849V – Symptoms of Failure

Vehicles:

• Nissan Almera
• Nissan Primera
• Nissan Almera Tino

Engine: 2.2 Di / dCi YD22 (100 kW)
Turbo model: GT1849V

The GT1849V variable-geometry turbocharger used in Nissan 2.2D YD22 engines provides strong mid-range torque and efficiency. Over time, however, it may fail due to soot buildup, oil contamination, high mileage, or improper maintenance.

Common Symptoms of Turbocharger Failure

1. Loss of Power

• Sluggish acceleration
• Reduced boost pressure
• Poor performance at higher RPM

2. Excessive Exhaust Smoke

• Blue smoke – oil leaking through worn turbo seals
• Black smoke – insufficient air supply or boost leak
• White smoke – oil entering the exhaust side

3. Unusual Noises

• Loud whistling or “siren” sound during acceleration
• Grinding or metallic noise (bearing or shaft damage)

4. Increased Oil Consumption

• Frequent need to add engine oil
• Oil present in intercooler hoses or intake system

5. Boost Control Problems

• Underboost or overboost fault codes
• Engine warning light (check engine)
• Limp mode activation

6. Variable Geometry (VNT) Malfunction

• Sticking vanes due to carbon buildup
• Delayed turbo response
• Irregular boost pressure

7. Shaft Play

• Excessive radial or axial movement
• Risk of turbine or compressor wheel contact with housing

Common Causes of Turbo Failure

• Poor oil quality or extended oil change intervals
• Blocked oil supply or return lines
• Carbon buildup from EGR system
• Engine overheating
• Foreign object damage

Recommendation

If your Nissan 2.2D YD22 (100 kW) shows any of these symptoms, immediate inspection of the turbocharger and lubrication system is recommended. Continued driving with a faulty turbo may result in serious engine damage or complete turbo failure.
