Dacia Dokker
Structurally simple, robust 1.6-litre naturally aspirated engine with high mileage potential. The water pump is the weak point: if it fails, the engine overheats and head gasket damage threatens. LPG variant with factory-fitted LPG system; observe 10-year tank re-certification and have injectors checked regularly.
Economical on gas
The 1.6 with LPG saves at the pump. Performance is adequate; the boot shrinks slightly due to the gas tank.
Engine Weaknesses 8
Timing belt due every 60,000–90,000 km. Not interference-free — a snapped belt means valve damage and total engine failure.
Symptoms: Timing belt due every 60,000–90,000 km
Trigger wheel shifts due to crankshaft axial play. TDC sensor loses signal; engine fails to start or runs rough.
Symptoms: Trigger wheel shifts due to crankshaft axial play
LPG burns hotter than petrol — valve seats wear faster. Check valve clearance every 30,000 km. Hardened valve seats fitted from the factory.
Symptoms: LPG burns hotter than petrol — valve seats wear faster
LPG tanks must be inspected and replaced if necessary after 10 years (mandatory inspection). Internal corrosion from condensation is possible.
Symptoms: LPG tanks must be inspected after 10 years
Same weakness as the K7J — valve fouls, engine stalls at idle. Cleaning usually helps.

Valve cover gasket becomes porous after 100,000+ km. Oil loss visible at the cylinder head. Inexpensive to replace.
Symptoms: Valve cover gasket becomes porous after 100,000 km
Landi Renzo LPG injectors foul up over time. Replace the gas filter every 15,000 km. Rough running in LPG mode is a symptom.
Symptoms: Landi Renzo LPG injectors foul up over time
LPG ECU (Landi Renzo) is encrypted — only specialist workshops can read it. Regular Dacia dealers are often unable to diagnose it.

Vehicle Weaknesses 6
From the third MOT onwards, the Dokker's foot brake is flagged as a defect at above-average frequency.
A recall was issued for vehicles produced February to April 2016 because metal swarf in the ABS control unit could impair brake pressure distribution.
The Dokker's axle suspension is cited as defective at above-average frequency during MOT inspections.
The sliding door mechanism tends to jam and fail. A recall covered vehicles produced July 2015 to September 2016 due to a faulty sliding door lock.
Oil leaks on the Dokker become noticeably more frequent from the second MOT onwards.
Window regulators and central locking frequently fail on the Dokker.
Reports & Tests
Only 55% of 8–9-year-old Dokkers pass without defects (average: 72.4%). Lighting up to six times more likely to be defective than the class average.
