The Fiat Punto Multijet has many fans, but owners report persistent problems with the diesel engine. Turbo wear, a clogged EGR valve, blocked crankcase ventilation and extreme oil consumption mainly affect the 1.3 JTD engine after 100,000 kilometres. These complaints are no coincidence, but result from design choices and maintenance dependency that you as an owner need to be aware of. Read on to find out what goes wrong and how to avoid expensive repairs.
Turbo wear: a creeping problem
The turbo of the 1.3 Multijet is known as a vulnerable component. Many owners only notice something is wrong when it is already serious. Power drops off. Or the engine produces smoke. The turbo vanes come loose or become damaged. The cause is often a lack of oil. The small oil capacity of the 1.3 engine makes this issue worse: there is very little margin for error.
Track down turbo problems by moving the turbo shaft on the intake side. Play indicates wear. Also measure the intake pressure while driving with a diagnostic tool. With a healthy turbo, the pressure doubles as soon as the turbo cuts in. If this does not happen, the turbo is no longer working properly.
How do I maintain the turbo of my Fiat Punto 1.3 Multijet?
Preventive maintenance is the best remedy. Check the oil level every month and top up when necessary. Always use the oil specified by Fiat and replace it at least according to the service intervals. Warm the engine up before driving off quickly and let it idle for a short time after a long trip. Cold starts under high load are deadly for the turbo.
Watch out for these symptoms:
- Loss of power when accelerating
- Whistling noises while driving
- Blue or black smoke from the exhaust
- Unusual vibrations at higher revs
If you notice these symptoms, have the turbo checked quickly. Waiting will worsen the damage and can lead to an expensive replacement.
‘ The result is loss of power, a misfiring engine and sometimes even overheating. ’
EGR contamination and its impact on performance
The EGR valve (valve that recirculates exhaust gases) recirculates exhaust gases to reduce emissions. In the Fiat Punto Multijet this component regularly becomes clogged due to soot build-up. This happens mainly on short trips where the engine does not reach operating temperature. The result is loss of power, a misfiring engine and sometimes even overheating.
A clogged EGR valve produces various symptoms. The engine runs unevenly, especially in the low rev range between 1,700 and 2,200 rpm. The engine warning light may also come on. In severe cases the car becomes difficult to start or even refuses to start.
How do I recognise EGR problems in my Fiat Punto diesel?
Diagnosis starts with reading fault codes via an OBD scanner (diagnostic device that reads the car’s fault codes). Codes referring to the EGR or air intake often point to this problem. Visual inspection also helps: remove the EGR valve and check for thick soot deposits. A healthy valve moves smoothly, a contaminated valve is stuck or responds slowly.
Cleaning is often sufficient if the valve is not mechanically damaged. Use special EGR cleaner or have the valve professionally descaled. In some cases replacement is necessary. Prevent recurrence by regularly taking longer trips where the engine gets properly warm.
Crankcase ventilation: clogged and forgotten
The crankcase ventilation system, also called the PCV system, removes excess gases and oil vapours from the crankcase. In the 1.3 Multijet this system clogs up quickly. That is due to the combination of short trips and oil burning. A clogged crankcase ventilation system increases pressure in the crankcase, which leads to oil leaks at gaskets and seals.
Recognisable symptoms are:
- Oil leaks around the cylinder head or oil pump
- Increased oil consumption without visible leakage
- Rough running or vibrations in the low rev range
- White smoke from the exhaust with a cold engine
Check the breather hose (ventilation hose of the crankcase ventilation system) and other parts of the system for cracks or blockages. Replacement is simple and prevents more serious damage. Have this checked during regular servicing.
Extreme oil consumption: a known defect
The 1.3 JTD engine has a notorious high oil consumption. Owners report usage of up to 1.5 litres per 1,000 kilometres, especially in older models. This is caused by worn piston rings, valves or cylinder head seals. The small oil capacity of only 3.5 litres makes the problem urgent: in a short time the oil level can become too low.
What should I do if my Fiat Punto diesel is using oil?
Check the oil level every 500 kilometres, especially on longer trips. Top up immediately when the level drops below the minimum. A low level causes permanent damage to the turbo and other moving parts. Never continue driving with the oil warning light on.
Investigate the cause by performing a compression test (measurement of pressure in the cylinders). Low compression in one or more cylinders points to internal wear. Also check for external leaks at the oil pump and seals. Check the cylinder head gasket as well. Leaks are easier and cheaper to fix than internal wear.
With consistently high consumption without leakage, repair is expensive. New piston rings or a cylinder head overhaul quickly cost more than the value of the car. In that case, consider regular topping up as a temporary solution or prepare for an engine replacement.
‘ Early detection saves expensive repairs. ’
Preventive maintenance avoids major costs
The problems mentioned are annoying, but largely preventable with proper maintenance. Replace the timing belt according to the schedule at 60,000 kilometres. Check the oil level monthly and top up using the correct specification. Use higher-quality diesel (premium brand) to reduce soot build-up.
Plan regular longer trips where the engine gets fully up to temperature. This helps to keep the EGR valve and particulate filter clean. During services, have the crankcase ventilation system and turbo checked. Early detection saves expensive repairs.
When buying a used Punto Multijet, always consider the service history. Cars without a DPF (diesel particulate filter) or with a complete service book are more reliable. Check for oil leaks, cooling system problems and the condition of the turbo before you buy.
Recognisable warning signs demand action
Owners on forums share similar experiences: the Multijet engine is reliable with correct maintenance, but demanding. Do not ignore warning signs. Loss of power, smoke or rough running indicate issues that will quickly escalate. A diagnostic tool helps you read fault codes. It also gives insight into important values such as fuel pressure and intake pressure. In addition, it shows the status of sensors.
Make sure you are familiar with the symptoms of turbo wear, EGR contamination and crankcase ventilation problems. Take action as soon as you notice anything unusual. Acting in time saves hundreds or even thousands of euros in repair costs.

Frequently asked questions
The most common engine problems with the Fiat Punto Multijet diesel are a clogged DPF filter, excessive oil usage and leaks, turbo and dual mass flywheel (DMF) wear, and faults in the EGR and cooling system. You recognise these from loss of power, increased smoke, more frequent regenerations or warning lights (engine/DPF), oil patches under the car or a rapidly dropping oil level, vibrations when accelerating and starting problems. Also watch for coolant loss, a rising temperature gauge and jerky or uneven running of the engine around 1,700–2,200 rpm. Regular checks of oil level, coolant, fault codes (OBD) and unusual noises or smoke help to detect these problems in time.
In the Fiat Punto Multijet diesel engines, the DPF particulate filter and the EGR valve/intake system in particular are prone to clogging and faults. In addition, the turbo (especially the blades) and the dual mass flywheel wear relatively quickly, especially with a lot of low‑rev driving. Oil leaks and increased oil consumption also occur due to seals and gaskets in the engine. Finally, the glow plugs and injectors are vulnerable components that can cause starting and running problems.
Check and change engine oil and filters (oil, air and fuel filter) strictly according to the schedule and use only good quality oil and diesel to limit wear, oil consumption and clogging of injectors. Take regular longer journeys at motorway speeds to keep the DPF particulate filter clean and reduce contamination of the EGR and intake system. Have the turbo and cooling system checked periodically (hoses, thermostat, coolant level) and avoid hard acceleration or switching off the engine immediately after heavy loading. Do not drive constantly at very low revs to limit DMF wear and vibrations, and read fault codes in good time with an OBD scanner to tackle emerging problems early.
Yes, clogged particulate filters (DPF) are common in the Fiat Punto Multijet, especially after around 100,000 km; the solution is forced regeneration, professional cleaning or replacement, combined with longer trips at operating temperature. The injection system can cause issues due to contaminated or leaking injectors and insufficient fuel pressure, which leads to starting problems and loss of power. Typical solutions are ultrasonic cleaning or refurbishing/replacing injectors and checking the fuel pump, filters and pipework. Good maintenance, high-quality diesel and timely reading of fault codes via OBD reduce the chance of these problems.
First check the basics: oil level, coolant level, visible oil leaks and the condition of the air filter. Then use a simple OBD2 scanner to read the fault codes and note in particular codes relating to fuel pressure, turbo/intake pressure, DPF and EGR. While driving, pay attention to symptoms such as loss of power, heavy smoke, rough running and overheating, and link these to what you see in the OBD data. In case of starting problems, check the battery, fuses and whether you can hear the fuel pump priming; only then go to the garage with your findings.
