Known engine issues
Bearing cap spinningThe most known problem of these engines is spinning of connecting rod bearing caps. This happens especially often with engines from Europe, where oil is changed every 30,000 km. Our regulations prescribe an oil change interval of 10,000 km and spins are rare, but many owners still prefer to renew the bearings every 60,000 km.
Delphi fuel systemMost diesels before 2009 are equipped with a Delphi Common Rail system, which does not tolerate air ingress, clogged fuel filter, or poor diesel. For any of these reasons, it starts generating metal shavings and primarily clogs the injectors. Also, this metal dust significantly reduces the life of the turbocharger and oil pump.
Siemens fuel systemThe fuel system from Siemens or Continental is much more reliable, but its repair costs more; the piezo injectors alone are several times more expensive. Therefore, there is no clear opinion on which brand's equipment is better.
Listed from most frequently reported, each with its source.
DPF clogging and regeneration problems
Often reported
The DPF can clog, especially in vehicles used for city driving or short distances; exhaust temperatures prevent effective regeneration.
Exhaust Emissions
Clogged EGR valve
Often reported
The 1.5 dCi engine is reported to have a tendency for the EGR valve to clog with carbon deposits; this can cause rough idling, check engine light, and reduced performance.
Exhaust Emissions
Injection system problems (pump/injectors)
Often reported
Pump and injector clogging are reported in the 1.5 dCi engine; this can cause starting issues, rough running, and warning lights.
Fuel System
Unusual noises from flywheel and clutch
Often reported
European forum users report unusual noises from the dual-mass flywheel or clutch components, especially on medium/high mileage models.
Transmission
Turbo rattle / wastegate noise
Often reported
Many users report a metallic rattle from the engine bay linked to the turbo. This is often due to a worn or faulty wastegate actuator. The issue can appear even on relatively new vehicles.
