Most Common Hyundai i20 (GB) Faults & Repair Costs
EPS flex-coupling and steering-column knock
The electric power-steering motor coupling can wear and produce a distinct knock or graunch through the wheel, especially at low speed or when shuffling into parking spaces.
Knock through steering wheel, Noise when rocking wheel left and right, Feels worse when parking
- Turn the wheel gently off-centre while stationary
- Drive slowly over rough surfaces
- Check for replacement-coupling history
DPF and EGR clogging on 1.1 CRDi
The smaller CRDi is economical but dislikes repeated cold starts and school-run use. When regeneration is interrupted too often, DPF and EGR faults quickly follow.
DPF or engine warning light, Cooling fan running after shutdown, Flat performance, Frequent regeneration attempts
- Ask about typical trip length
- Look for recent EGR, DPF or injector work
- Check exhaust smoke and idle quality from cold
Air-conditioning condenser leaks
Stone damage and corrosion at the front condenser are common enough to turn a seemingly tidy i20 into an air-con repair bill, particularly on motorway-used cars.
Weak air conditioning, Compressor cycles but cabin stays warm, Recent regas that did not last
- AC output on a warm day
- Condenser fins for stone damage
- Pipe unions for oily residue
