Tall, spacious mini-MPV built on the same platform as the Punto, produced in Serbia from 2012 to 2022. The 1.3 MultiJet II diesel is one of the most widely produced small diesels in Europe, used across Fiat, Alfa Romeo, Opel, and Suzuki models. In the 500L it produces 85 or 95 hp and is paired with a 5-speed manual or 5-speed MTA Dualogic automated manual. Popular with families for its roomy interior and low fuel consumption, though the 500L's below-average reliability reputation makes careful pre-purchase inspection essential.· more· less

Chain tensioner loses pressure over time, causing cold-start rattle and risk of chain skip · more· less
The 1.3 MultiJet uses a timing chain rather than a belt, but the tensioner is a known weak point. As the tensioner wears, it allows oil pressure to bleed off overnight, producing a distinctive rattle for a few seconds on cold start. This typically develops between 100,000 and 150,000 km, though neglected oil changes accelerate wear significantly. If ignored, the chain can stretch enough to skip teeth, causing catastrophic valve-to-piston contact. Replacement involves the chain, tensioner, guides, and sprockets. Independent workshop cost is around €800-1,200, while a Fiat dealer may charge €1,500-2,000. The oil pump is chain-driven on this engine, so timing chain issues can also affect oil pressure. Many well-maintained examples reach 200,000+ km on the original chain, so this is not inevitable but must be monitored.
Turbo wastegate seizing
€300 - 1,5002 of 7
Wastegate sticks from carbon buildup, causing overboost and limp mode · more· less
The small turbocharger on the 1.3 MultiJet has a mechanical wastegate that can seize from carbon and oily soot buildup. This is particularly common on cars driven gently or only on short trips, as the wastegate rarely fully opens and eventually sticks. Symptoms include the engine entering limp mode around 2,500-3,000 rpm with an overboost error code. In early stages the wastegate arm can be freed manually with penetrating oil and working it back and forth, costing only a workshop visit (€100-300). If the turbo internals are damaged, a full turbo replacement runs €1,000-1,500 at an independent shop. Regular spirited driving and occasional motorway runs help prevent this.
DPF clogging from short-trip driving
€200 - 1,5003 of 7
Diesel particulate filter blocks up on cars driven mainly in town · more· less
Like all modern diesels, the 500L's DPF needs regular passive regeneration through sustained driving at higher speeds. Cars used predominantly for short urban trips will experience incomplete regeneration cycles, leading to soot accumulation. When the DPF reaches a critical saturation level, the engine management light illuminates and performance drops. A forced regeneration at a workshop costs €100-200, chemical cleaning €200-400, and a full DPF replacement €800-1,500. This is essentially unavoidable on short-trip-only cars. The DPF regeneration process also introduces extra fuel into the engine oil, diluting it over time, which further stresses the timing chain and oil pump. DPF lifespan is typically 120,000-180,000 km with mixed driving.
EGR valve carbon buildup
€200 - 5004 of 7
EGR valve and intake manifold clog with carbon deposits, causing rough running · more· less
The EGR valve on the 1.3 MultiJet progressively accumulates carbon deposits, especially with short-trip city driving. Symptoms include rough idle, increased fuel consumption, black smoke under acceleration, and occasionally limp mode when the valve sticks open or closed. The intake manifold itself can also become heavily restricted with soot. Cleaning the EGR valve and intake manifold costs €200-300 at an independent workshop. If the valve is damaged and needs replacement, the part costs €100-250 plus labor, bringing total cost to €300-500. Fiat recommends cleaning every 80,000 km, though many owners need it sooner.
Variable displacement oil pump solenoid failure
€200 - 6005 of 7
Oil pressure warning triggered by faulty solenoid or wiring on the variable oil pump · more· less
The 1.3 MultiJet uses a variable displacement oil pump controlled by an electronic solenoid. The solenoid wiring is prone to breaking, and the O-ring gasket on the pump can deteriorate, triggering fault code P1541 (oil pump pressure stuck at minimum). The engine uses a virtual oil pressure sensor derived from other sensor data rather than a direct pressure sensor, which can complicate diagnosis. In most cases, replacing the solenoid wiring or O-ring resolves the issue for €200-300. If the oil pressure regulator on the chain housing needs replacement, costs rise to €400-600. The car typically enters limp mode or disables the start-stop system when this fault occurs.
Tailgate wiring harness fracture
€100 - 5006 of 7
Wires inside the rubber boot between body and tailgate snap from repeated flexing · more· less
The wiring harness that passes from the car body into the tailgate through a rubber grommet is subjected to bending stress every time the tailgate is opened. Over time, individual wires fracture inside the insulation, causing intermittent or complete failure of the rear wiper, number plate lights, demister, and tailgate release button. Dashboard warning lights may also illuminate erratically. Fiat dealers quote €400-600 for a complete wiring loom replacement, but aftermarket repair kits are available for €20-40. A competent workshop can splice in a repair harness for €100-200 total. This issue affects the majority of 500L models with high tailgate usage, typically appearing from 5-7 years of age.
Dualogic MTA actuator failure (if equipped)
€800 - 2,0007 of 7
Automated manual gearbox suffers from jerky shifts, hesitation, and eventual actuator failure · more· less
If the 500L is equipped with the 5-speed MTA Dualogic automated manual (rather than the standard 5-speed manual), be aware that this is a known weak point. The system uses a hydraulic pump and actuator to operate the clutch and shift gears automatically. Common failures include hydraulic pump motor wear, actuator malfunctions causing jerky or delayed shifts, and software calibration drift. Problems typically appear between 60,000 and 100,000 km. Repair costs range from €800 for actuator recalibration and fluid change to €1,500-2,000 for full actuator replacement. Manual gearbox versions are significantly more reliable and should be strongly preferred.
Reasonably reliable engine in a less reliable car
The 1.3 MultiJet II diesel itself is a well-proven unit with millions produced across multiple brands since 2003. With diligent maintenance and regular oil changes using the correct specification, the engine can comfortably reach 200,000 km and beyond. However, the 500L as a package adds wiring harness fragility, Dualogic gearbox issues (on auto models), and the typical diesel maintenance demands of DPF and EGR systems. Manual gearbox versions with full service history and evidence of regular highway driving are the safest choice. Avoid cars with cold-start rattle or missing service records.
Service history
Complete Fiat dealer or specialist records essential. Verify oil changes every 15,000-20,000 km with correct specification oil.
Tires
Check tread depth, age (date codes on sidewall), and uneven wear patterns. 500L uses 205/55 R16 tires.
Cold start
Start the engine completely cold. Listen carefully for rattling or ticking sounds in the first 30 seconds.
Test drive
Drive for at least 20 minutes including varied speeds. Monitor for warning lights, limp mode, and gearbox behavior.
Specific for this vehicle
Listen for timing chain rattle on cold start
A rattle lasting more than a few seconds indicates worn tensioner. If it persists or is loud, the chain needs replacement before purchase.
Test all tailgate electrics thoroughly
Check rear wiper, number plate lights, demister, and tailgate release button. Intermittent failures indicate wiring harness damage.
Check for oil pressure warnings
Drive for 10+ minutes and watch for 'insufficient oil pressure' messages. Check if start-stop works correctly, as it disables with oil pump faults.
+ 4 more checksShow less
Verify DPF regeneration status
Ask about driving patterns. Cars used for short trips only will have DPF issues. A diagnostic scan can show DPF soot loading percentage.
Check for EPC or engine warning lights under load
Accelerate firmly from 2,000 rpm in 3rd gear. If the engine enters limp mode at 2,500-3,000 rpm, the turbo wastegate may be seized.
Test Dualogic gearbox (if equipped)
Drive for 15+ minutes in various conditions. Feel for jerky shifts, delayed engagement, or clunking. Manual versions are strongly preferred.
Inspect alloy wheels for lacquer peeling
Many 500Ls suffer from peeling lacquer on alloy wheels. Not a safety issue but indicates general care level.
