Volvo V50

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 D5204T6, a breaking serpentine belt can get into the timing belt drive and cause severe engine damage. Inspect timing belt and serpentine belt condition together at every service. Timing belt replacement interval: 105,000 km or 10 years.

Symptoms: Scraping or clattering from the engine area, sudden engine stall, tensioner noises.

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 more heavily turbocharged D5204T6 shows injector leakage at higher mileages from the high injection pressure. Diesel enters the engine oil, dilutes it, and accelerates bearing wear. Check oil level and condition regularly.

Symptoms: Diesel in engine oil (oil level rises, diesel smell), rough idle, excessive fuel consumption, soot smell.

Springs break on the front and rear axles of the S40 II, V50 and C30 comparatively often, as MOT inspectors regularly find. The repair is straightforward but not cheap.

Alternator and starter motor fail relatively early on models built before 2005. Sudden power cuts or starting problems are typical symptoms. Replacement costs €400–700.

Door locking motors fail and produce metallic noises when closing. All doors can be affected; repair costs around €200 per door.

The thermostat is prone to malfunction and can cause excessively high or low operating temperatures. Coolant loss without a visible leak point to early cylinder head issues.
