Engine Weaknesses 4
The D5204 engines are VEA successor engines with an identical EGR cooler problem. Soot paste in the EGR system leads to throttling. The 2020 recall also applies to vehicles with D5204 engines.
Symptoms: EGR fault light, engine throttling, rough running, increased fuel consumption
On the D5204T5, a breaking serpentine belt can be drawn into the timing belt drive and destroy the timing belt — with immediate engine damage. Inspect timing belt and serpentine belt condition together at every service. Timing belt replacement interval: 105,000 km.
Symptoms: Loud clattering or scraping, sudden engine stall, noise from belt area.
The VEA successor D5204 has the same DPF vulnerability with short-trip use. Regular long-distance runs for active regeneration are necessary. DPF cleaning or replacement from 150,000 km.
Symptoms: DPF warning light, power loss, increased diesel consumption
The 1,800-bar common-rail injectors of the D5204T5 can leak at over 150,000 km mileage. Excessive return flow causes diesel in the engine oil, diluting it and accelerating bearing wear. Hydraulic tappets can start knocking from as early as 100,000 km with poor oil quality.
Symptoms: Rough idle, diesel smell from the dipstick opening, tapping from valve train on cold start.
