Peugeot 308 Problems: Common Issues and Repair Costs
The Peugeot 308 is a stylish and practical hatchback with good fuel economy and solid features. However, over time, some issues have become common across various model years. Whether you’re considering buying one or already own it, here’s a breakdown of typical problems and what they cost to fix in the UK.
1. Turbocharger and DPF Problems
Turbocharger Issues
Many diesel owners report power loss, smoke from the exhaust, or a whistling noise—all signs of a worn or failing turbo.
- Turbo replacement (new or reconditioned): £600 to £1,200
DPF Blockage
The diesel particulate filter can clog up with soot if you mainly drive short distances.
- DPF cleaning or forced regeneration: £200 to £400
- DPF replacement: £600 to £900
These are common issues in high-mileage diesel 308s.
2. Oil Leaks and Engine Wear
Owners have reported oil leaks from valve cover gaskets or sump seals. Some engines, especially older petrol models, also suffer from oil burning.
- Gasket replacement: £150 to £300
- Repairs for oil-burning (e.g. piston rings, valve seals): £500 to £1,200
If left untreated, these can cause long-term engine damage.
3. Timing Belt and Chain Failures
Timing Chain (Petrol Engines)
If the chain stretches or tensioners wear out, it can cause rattling or engine misfires.
- Timing chain kit replacement: £400 to £800
Timing Belt (Diesel Engines)
Should be replaced every 5 years or 60,000 miles. If it fails, you could face full engine rebuild costs.
- Belt and water pump replacement: £450 to £700
- Engine rebuild (after belt failure): £5,000 to £6,000
This is one of the most critical maintenance items for a diesel 308.
4. Electrical and Sensor Issues
Electrical faults are common across most model years.
Typical complaints include:
- ABS and ESP warning lights
- Cruise control or speed limiter failure
- Engine light randomly appearing
- Malfunctioning window switches or stalks
- Diagnostic scan: £60 to £150
- Individual sensor or switch replacement: £80 to £250
These issues are often more annoying than serious but can be costly if misdiagnosed.
5. Suspension and Steering Problems
Some owners notice knocking or rattling noises from underneath, especially at low speeds.
Common causes:
- Worn drop links or anti-roll bar bushes
- Faulty ball joints
- Loose heat shields causing vibration
- Suspension component repair: £100 to £300
- Full front-end suspension refresh: £400 to £600
- Heat shield fix or replacement: £50 to £150
6. Brakes and Clutch Wear
Brakes and clutch components wear with mileage but can fail early if the car is driven hard or tows regularly.
- Front pads and discs: £250 to £550
- Rear brakes: £200 to £450
- Clutch and dual-mass flywheel: £600 to £1,200
7. Service and Maintenance Costs
Maintaining a Peugeot 308 is relatively affordable if you follow the schedule and avoid major neglect.
- Full service (oil, filters, plugs): £250 to £400
- Interim service (oil and filter): £120 to £180
- Dealer diagnostic or ECU reset: £60 to £150
Independent garages typically charge less than dealers and often provide better value.

Owner Advice and Tips
- Replace the timing belt early, especially on diesel models. Never ignore a noisy engine or service light.
- Scan the car if warning lights appear, even if they go away. Small faults can hide bigger ones.
- Don’t delay turbo or DPF maintenance, especially on diesel engines used for short trips.
- Use reputable independent garages that know French cars. It saves money without sacrificing quality.
- Set aside £500 to £800 per year as a repair and maintenance budget after warranty ends.
Final Thoughts
The Peugeot 308 is a great all-rounder when properly maintained. Most of the common issues are avoidable with regular servicing and timely repairs. The biggest risks are related to engine timing and DPF on diesel versions, but even those can be managed with good care. If you’re buying used, always get a pre-purchase inspection and service history.
