Problematic

Reliability, common problems and owner reviews for the Skoda Octavia II 1.6 TDI 105hp (CAYC). Check this before you buy used.

Frugal common-rail 1.6 TDI, but the emissions hardware is the weak point: injectors fail expensively (~€1,800–2,500 for all four), the EGR is buried and labour-heavy, and the DPF clogs fast on short trips. Can reach 200,000+ km if driven hot and maintained — a poor choice for short city journeys.

Same engine, other cars

This is the same physical engine (CAYC) sold under different names across brands. Reliability is broadly shared — cross-check these:

Known Issues

Injector failurecritical

Injectors fail ~80,000–150,000 km, usually as a set. Not reconditionable; each needs IMA coding. No formal recall.

Fix / Workaround: Replace all four (~€1,800–2,500) with IMA coding. Factor into price.

Repair cost: €1800–€2500

Typically appears after: 80,000 km

EGR valve/cooler failurerecurring

Clogs with soot (P0402); buried by the firewall (5–6h labour).

Fix / Workaround: Clean/replace; expensive due to access.

Repair cost: €300–€700

DPF cloggingrecurring

Short trips prevent regen; replacement can exceed €1,500.

Fix / Workaround: Monthly sustained motorway runs; clean/replace if blocked.

Repair cost: €300–€1500

Mileage Thresholds

After 120,000 km: Injector and EGR failures cluster here.

Pre-Purchase Checklist

  • ☐Buy only if used mainly on longer/motorway journeys
  • ☐Scan for injector and P0402 codes
  • ☐Ask whether injectors were replaced (and IMA-coded)
  • ☐Check DPF condition / regen history
