About this model
The Fiat 500 is one of the most popular city cars on the roads of Bosnia and Herzegovina. Since its relaunch in 2007, this retro-styled city car has won over the market with its compact size, low fuel consumption and affordable running costs. In BiH we most commonly see it with the 1.2 8v Fire engine (code 169A4000) producing 69 HP — a reliable four-cylinder naturally aspirated unit whose roots go back to the 1990s. A typical example on the local market has 120,000–200,000 km and is 10–15 years old. Although it is fundamentally a simple car, it has specific weak points every owner should know about.
Engines and variants
This model is most commonly available in BiH with the following engines.
169A4000 (1.2 8v 69 HP) — The base and most common engine in BiH, a naturally aspirated 1,242 cc unit with 69 HP. It is reliable and economical, averaging around 5–6 l/100 km in combined driving. The most frequent issues are oil leaks through the PCV valve and gaskets, plus water pump and thermostat housing wear. Produced from 2007 to 2022, making it by far the longest-running engine in the range. Parts are the cheapest and most readily available of all variants, and its economy makes it an excellent candidate for an LPG conversion.
312A2000 (0.9 TwinAir 85/105 HP) — A twin-cylinder turbo engine with variable valve lift, livelier than the 1.2 but considerably more complex and expensive to maintain. It is known for excessive oil consumption (up to 1 litre every 2,000–3,000 km), leaks around the timing cover and vibrations inherent to a twin-cylinder layout. Produced from 2010 to 2022. It is rarer in BiH because it requires more specialised knowledge to service, and the oil consumption is problematic for owners who do not check the level regularly.
169A1000 (1.4 16v 100 HP) — The more powerful petrol option with 100 HP. It is rarer in BiH because fuel consumption is higher, but it is more dynamic for driving outside the city. It shares most problems with the 1.2 (EPS, mounts, electrics) but is less prone to oil leaks. Instead of a timing belt it uses a chain, which lasts longer. Produced from 2007 to 2015, it is bought by drivers who want more power for mixed city/open-road driving.
199B1000 (1.3 Multijet 75/95 HP) — The diesel variant with Fiat's well-known 1.3 Multijet engine, rare in BiH in the city-car class because short urban trips do not suit a diesel. Classic 1.3 Multijet problems include the dual-mass flywheel, exhaust system clogging on short runs and clutch vibration at 2,500–3,000 rpm. Produced from 2007 to 2018, but for typical city use of the Fiat 500 the petrol variant is a far more practical choice.
Reliability and reputation in BiH
The Fiat 500 1.2 8v is fundamentally a reliable city car when regularly maintained. The Fire engine is one of Fiat's most enduring units: it is simple, has no turbo, no timing chain to cause trouble, and is mechanic-friendly. The issues that do arise are mainly related to age and mileage, not to design flaws in the engine itself.
Parts are cheap and readily available in BiH. Most consumables cost less than for competitors like the Toyota Yaris or VW Polo. The biggest weakness is the electrics and the power steering — those repairs can be a more serious job if not addressed in time. Compared with the competition (Corsa D, Yaris, Polo 6R), the Fiat 500 is cheaper to buy but demands more regular attention to electrics and gaskets.
The typical owner is someone looking for an affordable city car with low consumption and character. In the workshop we most often see examples with 130,000–180,000 km that need a power-steering column or a gasket set, but whose engine and gearbox run without problems. It is not a car for the motorway and long trips, but for city driving and shorter runs it is an excellent solution.
Common faults we see
From our hands-on experience, here is what comes in most often for this model.
1. Electric power steering (EPS)
Symptom: The steering becomes heavy at low speeds and when parking. The power-steering warning light appears on the dashboard. Intermittent loss of assistance when turning.
The Fiat 500 uses an electric power steering (EPS) system with an integrated motor and control unit in the steering column. The torque sensor in the column is the most common cause of failure — fault code C1002 appears on the diagnostic tool. The problem affects all model years but especially cars older than 8–10 years. The entire steering column is a single assembly: motor, sensor and electronics.
Advice: Before replacing the whole column, check whether only the sensor is at fault — a sensor repair is considerably cheaper. Regularly check the battery condition because low voltage amplifies the symptoms.
2. Water pump and thermostat housing
Symptom: Coolant leaking under the engine, engine overheating, white smoke from the exhaust in extreme cases.
The water pump on the 1.2 Fire engine is a well-known weak point — it leaks after 80,000–120,000 km. Additionally, the plastic connector on the thermostat housing cracks from age and heat, causing a sudden leak. This is specific to the 1.2 8v engine because the plastic part does not withstand long-term thermal cycling.
Advice: When replacing the water pump, always replace the thermostat at the same time — the access point is the same, and their service life is similar. Inspect the plastic connectors on the housing; if they are brittle, replace them preventively.
3. Oil leaks (PCV valve and gaskets)
Symptom: Oil spots under the car, a burning smell from the engine, oil level dropping between services.
The Fire engine is prone to oil leaks in several places: the valve cover gasket, the oil pan gasket and the front/rear crankshaft seals. A common cause is a clogged PCV valve, which creates excessive crankcase pressure and forces oil past the gaskets. The problem worsens after 100,000 km and on examples that have not been regularly serviced.
Advice: Before going for the more expensive full gasket replacement, check the PCV valve. If it is clogged, replacing it alone often resolves the leak. Use a genuine Fiat PCV valve because aftermarket ones are frequently not of the same quality.
4. Ignition coils
Symptom: The engine misfires on one or more cylinders, jerking while driving, check-engine light, increased fuel consumption.
The Fiat 500 1.2 uses individual coil-on-plug ignition coils. They fail due to moisture and age, especially on cars that are parked outdoors. The engine begins to misfire, usually noticeable on one cylinder first. Fault codes P0300–P0304 are typical on the diagnostic tool.
Advice: Replace all four coils at once, not just the one that failed. The others are the same age and will soon follow. Always inspect the spark plugs when changing the coils.
5. Injector seals and fuel leaks
Symptom: A petrol smell in the cabin and around the engine, increased fuel consumption, unstable idle.
The rubber O-rings on the injectors dry out and lose elasticity, especially on cars older than 10 years. Fuel seeps around the injectors as vapour, which is also a fire risk. Fiat issued a service bulletin for replacing the O-rings (part 55215424).
Advice: If you smell petrol around the engine, do not delay the replacement. A fuel leak is a safety risk. Replacing all four sets of O-rings is a quick and inexpensive job.
6. Engine mount (lower rear)
Symptom: Vibrations when reversing, a thud when shifting from R to D, noticeable vibrations in the cabin at idle.
The lower rear engine mount on the Fiat 500 bears the greatest load because it holds the engine and gearbox to the subframe. The rubber in the mount cracks from vibration and age, typically after 80,000–100,000 km. The problem is more pronounced on cars driven on poor roads.
Advice: Inspect the mounts visually — cracks in the rubber are a clear sign. Replace the mount before it fails completely, because excessive engine movement can damage the driveshafts and the exhaust system.
7. Top strut mounts and bushings
Symptom: Knocking and creaking over bumps, especially on small potholes and speed bumps. Unstable steering at lower speeds.
The front top strut mounts wear out relatively quickly on the Fiat 500 due to the short wheelbase and firm suspension setup. The front control-arm bushings also deteriorate faster on bad roads. BiH conditions (potholes, unpaved roads) accelerate this by 30–40% compared with western European averages.
Advice: When replacing the shock absorbers, always replace the top strut mounts too — you will save on labour because the same assembly is being accessed. Check the bushings at every regular service.
8. Body Control Module (BCM) and electrics
Symptom: Wipers or lights activating on their own, central locking not working properly, dashboard glitches, warning lights coming on for no reason.
The BCM (Body Control Module) on the Fiat 500 is sensitive to moisture that gets in through blocked drain channels beneath the windscreen. Water runs down the scuttle panel and can reach the electronics. Corrosion on the connectors causes sporadic electrical faults that are difficult to diagnose.
Advice: Preventively clean the drain channels below the windscreen at least once a year. If strange electrical symptoms appear, first check for moisture around the BCM before replacing expensive components.
Service and maintenance
The Fire 1.2 8v engine uses a timing belt that should be replaced at 100,000–120,000 km or every 5 years, whichever comes first. Always replace the water pump at the same time. The recommended oil is 5W-40 (Fiat specification 9.55535-H2) with a change interval of 10,000–15,000 km depending on driving conditions: for predominantly city driving we recommend the shorter 10,000 km interval; for mixed driving 15,000 km is acceptable.
Spark plugs — NGK or Champion, replacement interval 25,000–30,000 km. Coolant (Fiat Paraflu UP type) should be changed every 4 years. Brake fluid DOT4 every 2 years. On examples with the Dualogic automated gearbox, the gearbox oil should be changed at 50,000–60,000 km depending on driving style and city conditions. Skipping this service leads to expensive actuator failures.
Owner tips
- Check the history before putting down a deposit: use the chassis number to pull the full history via carVertical. From international registers you get real odometer readings by date, recorded accidents, the number of previous owners and indicators of theft or total loss. We consider this essential before buying any used car, especially imports from Italy and Germany. When paying for the report you can use the code GAGA for a 20% discount.
- Clean the drain channels below the windscreen at least twice a year. Blocked channels are the main cause of BCM electronics failures.
- Check the oil level every two weeks. The Fire engine does not consume much, but leaks through gaskets can go unnoticed until the level drops critically.
- Use 5W-40 oil meeting Fiat spec 9.55535-H2 and change it at 10,000 km for predominantly city driving instead of the factory 15,000 km.
- Replace the plastic connectors on the thermostat housing preventively after 100,000 km. The plastic hardens and cracks without warning.
Frequently asked questions
Is the Fiat 500 1.2 8v a reliable car?
Yes, the 1.2 8v Fire engine is mechanically one of the more reliable units in the small city-car class. It is simple and cheap to maintain. The main concerns are the electric power steering and the electrics — those areas require attention — but the engine itself can last 250,000+ km with regular maintenance.
Is it worth fitting LPG to a Fiat 500 1.2?
The Fiat 500 1.2 8v is an excellent candidate for an LPG conversion. The naturally aspirated engine with multipoint injection handles LPG well, and the savings are significant given that this is predominantly a city car with frequent starts and stops. The only condition is that the engine must be in good condition before the conversion — pay particular attention to the coils and injectors.
How long does the timing belt last on a Fiat 500 1.2?
Fiat specifies replacement at 120,000 km or 5 years, whichever comes first. In practice, we recommend changing it at 100,000–110,000 km if you drive mainly in the city with frequent cold starts. Always replace the water pump at the same time.
Manual gearbox or Dualogic — which is better on the Fiat 500?
For BiH conditions, the manual gearbox is by far the better choice. The Dualogic is an automated manual with a single clutch — it judders in city traffic, and actuator and clutch repairs are expensive. If you want an automatic, look at a different model. The five-speed manual on the 500 is simple and practically indestructible.
What are the signs of power-steering failure on the Fiat 500?
The first sign is intermittent heavy steering when parking or turning slowly, accompanied by a warning light on the dashboard. The steering becomes heavy and then returns to normal. If you notice this symptom, do not wait for it to become permanent — get it diagnosed straight away. An early fix (sensor replacement) is significantly cheaper than a late one (full column replacement).
Does the Fiat 500 1.2 consume a lot of oil?
No, the 1.2 8v Fire engine is not known for oil consumption the way the 0.9 TwinAir is. Normal consumption is below 0.5 litres per 10,000 km. If it is using more, check the PCV valve and the condition of the gaskets. Excessive consumption on the 1.2 usually means a clogged PCV valve or worn valve-stem seals.
Is the Fiat 500 a good first car?
The Fiat 500 is a popular choice for a first car thanks to its low purchase price, low fuel consumption and compact dimensions ideal for city driving. Parts are cheap. The only note: check the power steering and electrical system before buying, because those repairs can be costly for a young person on a tight budget.
If you notice any of these symptoms, drop by the workshop — it is better to check early than to pay for an expensive repair later.
