Fiat 500 automatic (Dualogic): maintenance and common problems

The petrol Fiat 500 automatics you see on the road usually have a Dualogic. According to viaBOVAG, the consumer site of the Dutch motor trade association, the Dualogic is an automated manual: a manual gearbox that a robot operates automatically. You mainly find this type in small cars. It is relatively inexpensive, but according to viaBOVAG it is not known for its refinement. A noticeable break in pulling power during a gear change is therefore normal for this type of gearbox.

The Dualogic is a standard manual gearbox with a clutch, but without a clutch pedal. According to the ANWB, the Dutch motoring organisation, in an automated manual a computer and hydraulics take over operating the clutch. On the Dualogic they also do the gear changes.

The Dualogic has an automatic mode and a manual mode. In manual mode you choose the gear yourself with the gear lever, while the computer still operates the clutch. There is no clutch pedal.

Because the control unit takes over the clutch, it has to know the point at which the clutch bites. After the clutch or parts of the hydraulic unit have been replaced, the system has to learn this again. This is done with diagnostic equipment.

The complaints on a Dualogic resemble those of an automatic, but the causes are different. The table shows which complaints occur and what we look at first.

Overview by Autobedrijf Willemsbrug. The diagnosis determines the cause on your car.

According to viaBOVAG, an automated manual should not slip while accelerating in a gear. If it does, that can point to a worn clutch plate. A worn clutch plate has to be replaced. You can read more on our page clutch replacement in Rotterdam.

A Fiat 500 with a Dualogic needs the maintenance that Fiat prescribes in the service schedule, not a flush. So check the service book or the owner’s manual of your car. It tells you how often the car needs to go to the garage and what happens then. Good maintenance keeps your car working well and helps to find problems in good time.

During a service for your Fiat we check these points on a Dualogic:

1. Leaks: we check that the hydraulic unit, the lines and the gearbox are dry.
2. Fluid levels: we check the level of the hydraulic fluid and the gearbox oil as Fiat prescribes.
3. Fault memory: we read the control unit. Stored faults sometimes give an early warning, before you notice anything.
4. Battery: the Dualogic works electrically and hydraulically. A weak battery can cause gear-change faults. We test the battery and the charging voltage.
5. Test drive: we pay attention to pulling away, the gear changes and any clutch slip.

Do you have another car with a conventional automatic with a torque converter? Then a flush can be worthwhile. You can read how it works on our page automatic gearbox flush.

You can influence how long the clutch lasts. On a Dualogic the clutch wears in the same way as on a manual gearbox. The only difference is that there is no pedal. These habits help:

1. Hold the car on a hill with the brake. If you hold it with the accelerator, you let the clutch slip. That creates heat and wear.
2. Use the brake when stationary. In a traffic jam or at traffic lights, keep your foot on the brake instead of repeatedly giving a little throttle.
3. Pull away gently. When you pull away calmly, the clutch closes more smoothly and creates less heat than at full throttle from a standstill.
4. Use manual mode on a steep hill or with a full car. The gearbox then holds a lower gear and changes gear less often.
5. Keep the battery in good condition. If the car is slow to start or the battery often goes flat, have the battery tested. That matters for the Dualogic too.
6. Report complaints in good time. A clutch that has started to slip cannot be saved, but reporting it early prevents extra damage from driving on too long.

That depends on the cause. Relearning after a battery problem is something quite different from a new clutch or a repair to the hydraulic unit. That is why we start with a diagnosis. You receive a quote in advance and we only carry out repairs once you have agreed.

For comparison: according to the ANWB, a gearbox overhaul costs around € 2,500, including fitting. On a Dualogic, the problem is not necessarily in the gearbox itself. It can also be in the clutch, a sensor or the hydraulic unit.

Have you been advised elsewhere to replace the whole gearbox and are you unsure? Then you can have a second opinion with us for € 145, including up to one hour of investigation. You can read more about how we deal with faults on our page car diagnostics.

Is your Fiat also due for its APK (MOT), the annual Dutch roadworthiness test? With us, the APK for your Fiat costs € 50 for a petrol car. You can find us at Boterdiep 11 in Rotterdam-IJsselmonde, close to Stadion Feijenoord (De Kuip).

Yes. The petrol Fiat 500 is available as an automatic, usually with the Dualogic. This is a manual gearbox in which a computer and hydraulics operate the clutch and change gear. According to Fiat, the new Fiat 500 Hybrid has a six-speed manual gearbox.

You do not need to have a Fiat 500 with a Dualogic flushed. This gearbox has no torque converter and no automatic transmission fluid that controls the gear changes. Complaints are often caused by the clutch, the hydraulic unit or a sensor. Follow Fiat’s service schedule and have a diagnosis done if you notice complaints.

Often because of a worn clutch or a clutch that needs to be relearned. Too little hydraulic pressure or a sensor can also cause jerking. A slight dip in pulling power during a gear change is normal on a Dualogic, a hard jolt is not.

Check your car’s service book. It tells you how often the car needs to go to the garage. At every service we check the Dualogic for leaks, fluid level and fault codes. If you notice something in between, have it checked sooner.

No. Most checks and relearning the clutch require diagnostic equipment. What you can do yourself is spare the clutch and report complaints in good time. Leave the maintenance to a garage with the right equipment.

That depends a lot on use and maintenance. A lot of city driving, hills and holding the car with the accelerator make the clutch wear faster. A fixed lifespan cannot be given. The clutch is a wear part and can be replaced separately from the gearbox.

No. With us the APK costs € 50 for a petrol car, also if it has a Dualogic.

Yes. The Dualogic works with an electric pump and a control unit. If the voltage is too low, the gearbox can show faults or the car may not go into gear. That is why we also test the battery when there is a gear-change complaint.
