Dacia Logan
Renault's old-school engine with robust 8-valve technology — proven and low-maintenance. Timing belt replacement recommended every 60,000–80,000 km, as a failure causes severe engine damage. LPG variant with factory-fitted LPG system; observe 10-year tank re-certification and regular injector checks.
Everyday workhorse
The engine with 75 hp in the Logan is enough for everyday driving. Not exciting, but solid.
Engine Weaknesses 8
Timing belt must be replaced every 60,000–90,000 km. If neglected, engine damage threatens — not an interference-free engine.
Symptoms: Timing belt must be replaced every 60,000–90,000 km
Thermostat sticks open or closed. Engine does not reach operating temperature or overheats. Inexpensive to replace.
Symptoms: Thermostat sticks open or closed
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
Idle control valve fouls after 80,000+ km; engine stalls at idle or runs rough. Cleaning usually helps.
Symptoms: Idle control valve fouls after 80,000 km
Lambda sensor wears after 100,000+ km. Increased consumption and rough idle are symptoms.
Symptoms: Lambda sensor wears 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 8
Due to poor paint quality and inadequate corrosion protection, rust forms early on sills, wheel arches, and underbody. Vehicles in salt regions are particularly badly affected.
Recall for affected models due to rust on the rear shock absorber mounts. Structural weakening can compromise driving safety.
Steering and steering joints are among the most frequent MOT complaints. The defect rate is well above average for comparable vehicles.
Brake discs and pads wear faster than average on the Logan I. Regular MOT complaints, braking performance frequently insufficient.
The Logan I's exhaust system is known for early corrosion. A full replacement can be needed after just a few years and regularly causes MOT failures.
The Logan I's low beam shows far above average defect rates at MOT. According to inspection reports, front lighting is up to three times worse than average.
Recall for unreliable ABS warning light failures. The warning light malfunction can delay detection of ABS defects.
The Logan I's interior suffered from cheap plastics and poor panel gaps from the start. Over time, pronounced rattling develops from the dashboard and door panels.
