€150–2,000
EGR valve and cooler sooting (low-pressure EGR on early engines)
usually 80,000–200,000 km · Medium risk
Signs: Rough idle, power loss, EGR fault codes (P0400 range), regenerations do not finish
Fix: Check EGR position and flow in live data; clean or replace the valve, and the cooler if it is blocked or leaking
€300–1,200
Exhaust-side roller rocker arms wear (ticking, rough idle)
usually 60,000–250,000 km · Medium risk
