Turbocharger GTB1752V – Symptoms of Failure

Vehicles:

• VW T5 Van
• VW T5 Transporter
• VW Multivan T5
• VW Touareg
• VW T5 California

Engines:

• 2.5 TDI 4motion
• 2.5 TDI R5

Power Range: 77–128 kW
Turbo model: GTB1752V

The GTB1752V turbocharger is widely used in VW T5, Touareg 7L, and related vehicles. Despite its robustness, over time it may fail due to high mileage, oil contamination, soot buildup, or improper maintenance.

Common Symptoms of Turbocharger Failure

1. Loss of Engine Power

• Weak acceleration, especially under load
• Poor boost pressure
• Hesitation or sluggish response

2. Excessive Exhaust Smoke

• Blue smoke – oil leaking past worn seals
• Black smoke – insufficient air or boost leak
• White smoke – oil entering exhaust

3. Unusual Turbo Noises

• High-pitched whistling or siren sound
• Grinding or metallic noises (bearing/turbine damage)

4. Increased Oil Consumption

• Frequent oil top-ups
• Oil traces in intercooler pipes or intake system

5. Oil Leaks Around Turbocharger

• Visible oil on compressor/turbine housing
• Oil residue in intake piping

6. Boost Pressure Problems

• Underboost or overboost warnings
• Engine warning light activation
• Limp mode

7. Shaft Play

• Noticeable radial or axial movement of turbo shaft
• Possible contact between turbine/compressor and housing

Common Causes

• Poor or old engine oil
• Blocked oil feed or return lines
• Soot buildup from EGR/DPF systems
• Engine overheating
• Abrupt shutdown after heavy load

Recommendation

If your VW T5, Multivan, California, or Touareg with a 1.9–2.5 TDI engine shows any of these symptoms, the turbocharger should be inspected immediately. Driving with a failing turbo can lead to severe engine damage or total turbo failure.
