Engine: 2.0 TDI
Power range: 88–110 kW (120–150 PS)
Turbo type: BV43B (Variable Geometry Turbo – VNT)

Compatible Vehicles

• Audi A4 2.0 TDI 88–110 kW (CAGC / CJCC / CAGA / CAGB / CJCA / CJCB / CMFA / CJCD / CMFB)
• Audi A5 2.0 TDI 100–110 kW (CAGB / CJCB / CAGA / CJCA / CMFA / CJCD / CMFB)

Common Symptoms of Turbocharger Failure

1. Loss of Engine Power

• Sluggish acceleration
• Weak or delayed boost
• Reduced performance under load

2. Excessive Exhaust Smoke

• Blue smoke – oil leaking through worn turbo seals
• Black smoke – insufficient air supply / boost leak
• White smoke – oil entering exhaust system

3. Unusual Turbo Noises

• High-pitched whistling or siren sound
• Grinding or metallic noise (shaft or bearing damage)

4. Increased Oil Consumption

• Frequent oil top-ups
• Oil present in intercooler or intake hoses

5. Boost Pressure Problems

• Underboost / overboost fault codes
• Check engine light illuminated
• Limp mode activation

6. Variable Geometry (VNT) Malfunction

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

7. Excessive Shaft Play

• Radial or axial movement
• Risk of turbine/compressor wheel contact with housing

Common Causes

• Extended oil change intervals or poor oil quality
• Carbon buildup from EGR / DPF system
• Blocked oil feed or return lines
• High thermal load
• Improper engine shutdown after heavy load

Recommendation

If your Audi A4, A5, A6, Q5, or Seat Exeo 2.0 TDI with BV43B turbo shows these symptoms, immediate inspection of the turbocharger and lubrication system is recommended. Continuing to drive with a failing turbo may result in serious engine damage or complete turbocharger failure.
