Turbocharger GT1752S – Symptoms of Failure

Vehicles:

• Renault Vel Satis
• Renault Espace
• Renault Laguna

Engine: 2.0 dCi M9R (173 HP / 127 kW)
Turbo model: GT1752S

The GT1752S turbocharger installed in Renault 2.0 dCi M9R engines is designed for strong performance and efficiency. However, due to high mileage, oil contamination, EGR/DPF-related soot buildup, or extended service intervals, turbocharger failure may occur.

Common Symptoms of Turbocharger Failure

1. Loss of Engine Power

• Weak 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 – possible oil entering exhaust housing

3. Unusual Noises

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

4. Increased Oil Consumption

• Frequent oil top-ups
• Oil inside intercooler hoses

5. Oil Leaks Around Turbo

• Oil visible on compressor/turbine housing
• Oil residue in intake system

6. Boost Pressure Issues

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

7. Shaft Play

• Noticeable radial or axial movement of turbo shaft
• Risk of turbine wheel contact with housing

Common Causes

• Poor oil quality or delayed oil changes
• Blocked oil feed/return lines
• Carbon buildup from EGR/DPF system
• Overheating
• Improper engine shutdown after heavy load

Recommendation

If your Renault 2.0 dCi M9R (173 HP) shows any of these symptoms, the turbocharger and lubrication system should be inspected immediately. Driving with a faulty turbo can lead to serious engine damage.
