How To Fix
- Test each plug — open circuit = failed
- Soak in penetrating fluid before removal
- Never force a seized plug
- Replace all four — NGK or Bosch recommended
- Cost: £100-200

Other Faults on This Variant
Timing Belt Failure
CriticalThe 1.4 TDI Fabia has a timing belt with a 60,000-mile or 4-year interval. Belt failure on this interference engine is catastrophic — bent valves and destroyed pistons are the result.
DPF Blockage
ModerateThe small 1.4 TDI Fabia is often used for city commuting — the exact use case that blocks DPFs. The engine's small displacement means low exhaust temperatures even at motorway speeds.
EGR Valve Failure
ModerateEGR valve carbon build-up on the 1.4 TDI Fabia restricts airflow and causes power loss. The small engine is particularly sensitive to EGR restriction.
