Diagnostics and fault-finding at Ensjø in Oslo
Is a warning light on, is the car behaving differently, or does the fault only appear now and then? We combine diagnostic equipment with targeted checks to find the cause and agree the next step.
A fault code is a clue
A fault code identifies the system in which the car has registered an anomaly, but it does not always identify the part that caused it. A completed diagnosis may therefore require electrical measurements, mechanical checks or testing while the fault is present.
Prices for the first step
Prices include VAT per car. The NOK 1,490 diagnostic test covers reading and printing fault codes. The NOK 2,950 package includes 0.5 hours of fault-finding. Further fault-finding or more time is agreed separately before we continue.
Typical symptoms we investigate
- An engine light or other warning lights on the dashboard
- Rough running, loss of power or the car entering reduced-power mode
- Starting problems, battery problems or unexpected power drain
- Intermittent faults that come and go
- Electrical functions that are unstable or have stopped working
The car will not start, but the lights work.
Dashboard lights alone do not explain why the car will not start. Describe what happens when you try: is the car silent, does it click, or does the starter turn without the engine starting? On an electric car, state whether it becomes ready to drive and which message appears. We use the description to agree the first step in the investigation.
The car will not start with a new battery.
State when the battery was replaced and whether the fault was present before. A battery replacement alone does not establish the cause of the starting problem. We agree which checks the car needs and what has already been investigated. For repeated loss of power, read more about a battery that keeps going flat.
The car sometimes starts and sometimes refuses.
Tell us whether the fault appears with a cold or warm car, after parking or in particular weather conditions. Copy the warning text when it appears. Intermittent faults may require investigation while the fault is present; we cannot promise a particular cause from the description.
The engine warning light is on, even though the car seems normal.
A car that feels normal does not establish what a warning means. State which light or message you see and whether it is constant or intermittent. Reading fault codes may provide a clue; further measurements and checks may be needed for a complete diagnosis. See the prices and scope of the first step on this page.
Follow the car's owner's manual. If it tells you to stop, or braking or steering changes noticeably, stop in a safe place and arrange help before driving further. A contact form is not an emergency service or confirmation that the car is safe to drive.
Include the registration number and a short description. An employee confirms the time and price.
How the diagnostic process works
- We clarify the symptoms, when the fault occurs and what has already been tried.
- We read relevant fault codes and available live data from the car.
- We carry out targeted checks and measurements to confirm the actual cause.
- We explain the findings and agree a price or estimate before further repairs.
Before your appointment
Provide the registration number, mileage, warning messages and when the fault occurs. Photos of dashboard messages and information about recent work on the car can make the first step more precise.
Frequently asked questions about diagnostics
What do a diagnostic test and fault-finding cost?
A diagnostic test with printout costs NOK 1,490 including VAT and covers reading and printing fault codes. A diagnostic test with printout and 0.5 hours of fault-finding costs NOK 2,950 including VAT. Further fault-finding or more time is agreed separately before we continue.
Is reading a fault code the same as a completed diagnosis?
Not always. A fault code points to a system or anomaly, but targeted checks and electrical measurements may be needed to find the actual cause.
Can you help with most car makes?
Yes. We use diagnostic equipment that covers most car makes, whether petrol, diesel, hybrid or electric. Give us the registration number when you contact us, and we will check what applies to your car.
Can I keep driving when a warning light is on?
For a red warning light, stop safely and contact us before driving any further. For other warnings, follow the car's handbook and contact us if you are unsure.
