The Renault Trafic is a staple in the UK’s light commercial van market. Known for its comfort, payload capacity, and efficiency, it’s widely used by tradesmen, delivery companies, and fleet operators. But like any commercial vehicle, the Trafic has several known problems that can show up with age or heavy use. In this guide, we outline the most common Renault Trafic issues and give you realistic UK-based repair cost estimates, so you can budget accordingly or make a smart buying decision.

1. EGR Valve Blockage (Diesel Models)

What it is:
The Exhaust Gas Recirculation (EGR) valve helps reduce emissions but can get clogged with carbon deposits, especially on short-trip vans or those driven mostly in town.

Symptoms:

  • Loss of power
  • Engine warning light
  • Poor fuel economy

UK Repair Cost:

  • EGR valve cleaning: £120 to £180
  • EGR valve replacement: £250 to £450
  • Total: £120 to £450

2. Injector Failure (1.6 dCi and 2.0 dCi Engines)

What it is:
Injectors can fail due to wear or fuel contamination, causing rough idling, misfires, or difficulty starting. It’s a common issue on high-mileage Trafics.

Symptoms:

  • Poor starting
  • Engine shaking or knocking
  • Warning light on dashboard

UK Repair Cost:

  • Diagnostic scan: £60 to £100
  • Injector replacement: £250 to £350 each
  • Labour: £100 to £150
  • Total (for 1 to 4 injectors): £350 to £1,600

3. Gearbox Problems (Manual and EDC Automatic)

What it is:
Manual models may suffer from worn clutch or selector forks. EDC (dual-clutch) automatic versions can develop shifting issues or total failure.

Symptoms:

  • Crunching when changing gear
  • Gears not engaging
  • Jerky or delayed shifts

UK Repair Cost:

  • Gearbox oil change (EDC): £120 to £180
  • Clutch kit replacement: £450 to £750
  • Full gearbox rebuild: £1,200 to £2,500
  • Total: £120 to £2,500

4. Turbocharger Failure

What it is:
Turbochargers can wear out, especially on vans that tow or carry heavy loads regularly. Oil starvation or poor maintenance are common causes.

Symptoms:

  • Whining noise under acceleration
  • Loss of power
  • Smoke from exhaust

UK Repair Cost:

  • Turbo rebuild: £500 to £800
  • New turbocharger: £800 to £1,200
  • Labour: £250 to £400
  • Total: £750 to £1,600

5. Timing Chain Rattle or Failure

What it is:
Some newer Trafic engines use timing chains instead of belts. Chains are long-lasting but can stretch over time, especially without proper oil changes.

Symptoms:

  • Rattling noise on cold start
  • Engine misfire
  • Poor fuel economy

UK Repair Cost:

  • Timing chain kit: £200 to £300
  • Labour: £400 to £600
  • Total: £600 to £900

6. Rear Door Lock or Latch Failure

What it is:
A common wear-and-tear item, the rear door latch or lock can fail due to constant use, rust, or cable failure.

Symptoms:

  • Doors won’t lock or unlock
  • Rear doors jammed shut
  • Loose or stiff door handle

UK Repair Cost:

  • Lock or latch replacement: £100 to £180
  • Labour: £60 to £100
  • Total: £160 to £280

7. DPF Blockage or Warning

What it is:
The Diesel Particulate Filter can clog over time, especially if the van is mostly used for short city trips. Ignoring DPF warnings can lead to expensive repairs.

Symptoms:

  • DPF warning light
  • Limp mode
  • Rough idle or hesitation

UK Repair Cost:

  • Forced DPF regeneration: £100 to £200
  • Sensor replacement: £100 to £150
  • New DPF: £900 to £1,200
  • Total: £100 to £1,200

Final Thoughts

The Renault Trafic is a dependable and comfortable van, but it is not without its weak points. Most common problems come from diesel engine components, clutch or gearbox wear, and emissions systems. These issues are typical for vans used in commercial settings with higher mileage.

If you’re planning to buy a used Renault Trafic, especially for business use, it’s essential to check the service history, clutch condition, and whether the timing chain or turbo have been replaced. To stay protected, consider booking a pre-purchase inspection with CAREXAMER, the UK’s most trusted mobile inspection service.
