All Known Issues

Rear pneumatic air suspension bellows failure

SeriousSuspension & Chassis

Exclusive models equipped with rear pneumatic self-levelling suspension suffer from perish and cracking of the rubber air bellows. Air leaks cause the rear suspension to collapse overnight, forcing the air compressor to run continuously until it burns out, resulting in a harsh unyielding ride and suspension failure alerts.

Est. Repair Cost: £350–£900
Warning Signs:

Rear of car drops onto bump stops overnight or when parked, Suspension Fault warning message displayed on instrument screen, Air compressor under boot floor runs continuously or fails to activate, Bouncy, jarring ride over bumps from collapsed rear suspension

What to Inspect:
  • Inspect vehicle ride height after standing; rear should sit level with front
  • Listen for rear compressor operating and shutting off promptly when loading boot
  • Check rubber air bellows for cracking, perished rubber, or conversion to coil springs

EGS automated transmission clutch judder and false neutral

SeriousGearbox & Transmission

The six-speed Electronic Gearbox System (EGS) automated manual utilizes electro-hydraulic actuators for clutch control. Wear in the clutch friction plate, software miscalibration and hydraulic actuator seal failure cause pronounced judder pulling away, hesitant gear selection, or dropping into false neutral during low-speed deceleration.

Est. Repair Cost: £450–£1,100
Warning Signs:

Severe judder and jerking when pulling away from rest, Gearbox drops into false neutral when slowing down to roundabouts, Gearbox Fault message on central display and refusal to engage drive, Sluggish gear changes with excessive pause between ratios

What to Inspect:
  • Test low-speed crawling and parking manoeuvres to detect clutch snatch or judder
  • Decelerate smoothly to a stop from 30mph to verify gearbox downshifts cleanly without neutral drop
  • Check service history for clutch actuator recalibration or replacement invoices

Electronic parking brake actuator mechanism fault

ModerateBrakes

The electric parking brake (EPB) uses an electric motor and cable control unit mounted underneath the vehicle. Corrosion of cables from UK road grime and moisture ingress into the control unit cause the parking brake to bind, fail to release automatically on drive-off, or illuminate yellow parking brake fault warnings.

Est. Repair Cost: £250–£650
Warning Signs:

Handbrake Warning Fault message on central display screen, Parking brake fails to release automatically when pulling away, Rear brakes binding, causing hot alloy wheels and burning pad smell, High-pitched screeching from underfloor EPB motor during engagement

What to Inspect:
  • Test electric handbrake engagement and release manually via dashboard switch
  • Verify smooth automatic drive-off release on level ground and on an incline
  • Check rear brake discs for overheating discolouration or uneven pad wear

Buying Tips for 2006 Citroën C4 Picasso (Mk1)

  • The 2.0 HDi with traditional 6-speed torque converter automatic is far more reliable and relaxing than the jerky EGS automated box
  • Check that the rear suspension raises quickly and levels itself when luggage or passengers are placed in the boot
  • Verify all five or seven seats unfold and latch firmly without broken plastic release catches
