Common Citroën C4 Picasso Problems and Repair Costs
1. EGR Valve and DPF Blockages (Diesel Models)
Symptoms: Power loss, engine warning light, poor fuel economy
Causes: Carbon build-up in EGR valve or a clogged diesel particulate filter
Fix costs:
- EGR clean or replace: £150 to £350
- DPF regeneration or forced clean: £180 to £300
- New DPF: £800 to £1,200
Most common on 1.6 HDi engines, especially if used for school runs or short trips. Diesels need regular motorway driving to keep the system clean.
2. Timing Belt Degradation (1.2 PureTech Petrol)
Symptoms: Rattling sound on startup, oil warning light, rough idle
Causes: Belt breaking down inside engine oil
Fix costs:
- Timing belt kit and oil flush: £600 to £800
- Timing belt, sensors and full service: £850 to £1,000
This issue can cause severe engine damage if ignored. Citroën recommends changing the belt every 60,000 miles or 5 years, whichever comes first.
3. Suspension Noises and Handling Problems
Symptoms: Knocking from front, uneven tyre wear, loose steering
Causes: Worn suspension bushes, drop links or strut top mounts
Fix costs:
- Drop links: £100 to £150
- Bushes or control arms: £150 to £250
- Wheel alignment: £60 to £90
The front suspension works hard due to the vehicle’s size. Noises over speed bumps or poor tyre wear are common signs of wear.
4. Electric Handbrake Faults
Symptoms: Handbrake won’t release, handbrake light flashes, car rolls after parking
Causes: Faulty handbrake motor, sticky rear calipers, brake switch error
Fix costs:
- Handbrake motor: £250 to £400
- Rear brake caliper: £120 to £180 each
- Brake pedal switch: £50 to £80
This system is known to fail on higher-mileage models, often caused by water ingress or low voltage during cold starts.
5. Electrical and Dashboard Glitches
Symptoms: Warning lights, touchscreen freezing, electric windows not working
Causes: Failing battery, faulty BSI module, moisture in connectors
Fix costs:
- Battery and alternator test: £60 to £100
- BSI unit replacement: £250 to £600
- Touchscreen replacement: £300 to £500
A weak battery can cause multiple warning lights and random electrical problems. Always test the battery before assuming a module is faulty.
6. Air Conditioning and Heating Issues
Symptoms: Only hot or cold air, weak airflow, no response on fan
Causes: Blower motor resistor, heater flap failure, refrigerant leak
Fix costs:
- AC regas: £60 to £90
- Blower resistor: £90 to £130
- Heater actuator motor: £120 to £180
Climate control is prone to failure, especially in older models. Sometimes it’s a simple fuse, but the actuator gears often wear out too.
7. Gearbox Problems – ETG and EAT6
Symptoms: Jerky gear changes, lag pulling away, gearbox warning light
Causes: Gearbox actuator wear, low fluid, internal clutch faults
Fix costs:
- Software reset and fluid change: £180 to £250
- Gearbox actuator: £400 to £600
- Full gearbox rebuild (rare): £1,200 to £1,800
The semi-auto ETG box is known for jerky performance. The EAT6 automatic is smoother but still needs servicing every 40,000 to 60,000 miles.
