Car diagnostics in Helsinki
We find the faults in passenger cars and small vans before replacing parts. The same symptom can have several different causes – repairing on a guess alone often ends up costing more.
The time depends on the faultWe give you a time estimate when you book. If more time is needed than estimated, we tell you and agree on the next steps with you.
- Diagnostics 85 €/h
- Basic inspection 20 €
- Fault code reading 20 €
- Extra work only with your approval
85 €/h
Diagnostic work. When thorough, step-by-step diagnostics are needed: checking live data, measurements, a test drive, examining components or partial dismantling.
Quick checks
Basic inspection
20 €
For simple situations where the problem can be assessed visually, with a short check or by lifting the car on the lift.
Fault code reading / OBD
20 €
Reading fault codes and basic interpretation. Does not include adaptations, coding, measurements or deeper diagnostics. Read more
Good to know: the time diagnostics take depends on the fault – thorough diagnostics often take several hours, and for intermittent faults an accurate estimate in advance is difficult. We give you a time estimate when you book. If it turns out during the work that expensive or lengthy extra work is needed, we stop and check with you whether the price and schedule suit you – and suggest other options if needed.
Prices include VAT at 25.5%.
A fault code is not a finished diagnosis
A fault code does not always mean that the part mentioned in the code description should be replaced.
- a sensor fault code can be caused by the sensor, the wiring, a poor connection or a fault in another component
- if needed, we also check live data and other information related to the problem
- not all faults show up on the diagnostic tool
How we inspect
We choose the method according to the symptom
Mechanical faultsNoises, vibrations, suspension and brake faults require a mechanical inspection.
Not just the toolThe inspection is not limited to plugging in a diagnostic tool.
Intermittent faults
Some faults only show up in certain conditions – and they cannot always be brought out in a first short check.
- with a cold or warm engine
- when accelerating, braking or turning
- at a certain speed or after a longer drive
Help us
Describe the symptom as precisely as possible
When and whereThe more precisely you describe when the problem occurs, the easier it is to choose the direction of the diagnostics.
More time if neededSometimes a longer test drive, wider diagnostics or a new inspection is needed.
Electrical faults
During diagnostics we check electrical causes related to the specific problem.
- supply voltage, fuses and connectors
- individual sensors and actuators
- easily checked wiring
- we do not specialise in demanding auto-electrical work and control unit repairs – we tell you this after the initial inspection

Frequently asked questions
How much do diagnostics cost?
A basic inspection and fault code reading cost 20 €. More extensive diagnostics are charged by the hour at 85 €/h. We estimate the time needed when you book, based on the symptom and the model – if it turns out during the work that more time is needed, we tell you and agree on the next steps with you.
How long do diagnostics take?
It depends on the fault. Thorough diagnostics often take several hours; for intermittent faults and when several possible causes have to be ruled out, it takes longer. We give you a time estimate when you book and always agree on the next steps with you.
What if it turns out during diagnostics that expensive or lengthy extra work is needed?
We stop the work and contact you: we tell you what we found, how much continuing will cost and how long it will take. We do not continue without your approval.
If the price or schedule does not suit you, we suggest alternatives – a different repair method, moving the work to another day or reassembling the car in its current state so that you can decide in your own time.
Can the repair be done during the same visit?
Sometimes a small repair can be done straight away if the parts are available and the schedule allows. Otherwise we prepare a quote and agree on a separate time for the repair.
Is extra work done without asking?
We work as agreed with you when you book. If you want to approve each step separately, we always stop and ask – even for small extra jobs. If, on the other hand, we agree that small extra jobs can be done without asking, we do them straight away.
Many customers give permission in advance: “fix whatever is needed, get the car sorted”. This speeds up the work and usually also works out cheaper, because the work goes ahead without interruptions. Even then we keep you informed: if the total cost of the repair starts to grow noticeably or we find new major faults, we tell you and agree on the next steps – so that the final bill does not come as a surprise.
