Computer diagnostics
We detect up to 90% of faults at the diagnostics stage
Car diagnostics here is free, permanently. What to repair and when is entirely your decision – our job is to point out the faults and any risks clearly, if there are any.
Why your car needs it
The same symptom can point to several different causes, so without a check it's easy to fix the wrong thing.
The sooner a fault is found, the better the chance to fix it faster and cheaper.
What seems minor today can grow into a serious and costly repair over time.
Proper diagnostics avoids guesswork and needless replacement of working parts.

Reviews
I recommend this workshop – they work precisely and on time, send photos and explain every detail. My husband and I will be back. Thank you for your work!
Translated from UkrainianGenuinely impressed with the service. They replaced the consumables quickly and without unnecessary questions. Big plus for the photo report – it builds trust in a workshop instantly!
Translated from UkrainianCame in for a detailing wash and left seriously happy! The work was done fast and thoroughly, and the price was a pleasant surprise. Definitely recommend!
Translated from UkrainianCame in with the tyre-pressure warning light on. They sorted it in 30–40 minutes. Very polite staff and a comfortable place to wait. Recommend :)
Translated from UkrainianLovely, professional service and the mechanics really know their job. And the waiting area is amazing – I should come more often 😂 100% happy with the work. Recommend 🔥
Translated from UkrainianGreat workshop. They found why my parking lights weren't working – simply oxidised contacts. Cleaned them and didn't even charge me. Recommend!
Translated from UkrainianHuge thanks to the guy who saved the day with the seat in my car, even though I turned up at the very end of the working day. I recommend this workshop for being human and professional!)))
Translated from UkrainianHad my car serviced in Warsaw: oil change, full diagnostics, and they quickly found a wiring fault – all in about half an hour. The mechanics explained everything clearly.

Book now →No. A fault code only tells you which sensor recorded a deviation – the same code can mean a faulty sensor, an air leak or damaged wiring. That's why we also read the values with the engine running and check how the car behaves on a test drive.
A generic scanner sees general engine faults; a dealer protocol reaches every control unit of that specific make – gearbox, ABS, airbags, cabin electronics. On modern cars most faults sit exactly where a universal scanner cannot reach.
Usually 30 minutes to an hour and a half depending on the symptom – reading the codes is quick, tracking down an intermittent fault takes longer. We give you a time estimate right at intake.
Don't put the check off. It's often a fault that doesn't affect driving yet but is already damaging something expensive – the catalytic converter or the injectors. Checking now costs less than replacing the part a month later.
Yes – we log the parameters while driving and line them up with the moment the symptom appears. It takes longer than a plain code read, but it's the only way to see a cause that never gets stored in the control unit's memory.
Nothing – diagnostics here is free, permanently, whether or not you go ahead with the repair. We show you what we found; the decision about the work is yours.
Computer diagnostics at the RemZone workshop
Computer diagnostics is today the most reliable way to find a fault and extend the life of a car's components. Even with a hidden fault, this procedure helps locate the problem. Our RemZone workshop in Warsaw offers a full check of every vehicle system using modern digital equipment.
Finding and clearing faults in good time prevents expense later. At our Warsaw workshop the assessment of a car's condition is priced fairly. Engine computer diagnostics is carried out by our qualified technicians, who bring both practical skill and long experience.
How do you know your car is due for diagnostics?
Every modern vehicle is fitted with electronic sensors that analyse and monitor the condition of the main components. If something is wrong, a warning light comes on. That is the signal to find a suitable workshop and have full diagnostics done in Warsaw, Poland. We recommend the procedure at least once a year. There are situations, though, where the check may be needed sooner: if the car has stood unused for a long time, before buying or trading a car, when there is an existing fault and you want to rule out further problems, or after an accident.
You may need computer diagnostics of the engine and other systems if handling has deteriorated, you hear noises or knocking from under the bonnet, the exhaust smoke has changed colour, the engine has started overheating regularly, there are jerks when changing gear, or some of the dashboard controls have stopped working.
How do we run the computer analysis?
Diagnostics begins with a computer scan. At this stage the fault codes are read from the car's control units. The technicians then establish whether the sensors are doing their job and whether there are errors in the electronics, lighting or audible warnings. Our workshop carries out a full check-up: the suspension, brakes, steering and other key assemblies. The specialists also assess the condition of the fluids, the cooling system and the fuel system, so you can be confident your car is safe and reliable.
Once the faults are identified, a detailed report is drawn up with recommendations for repair and for replacing parts and assemblies. Where needed, the service intervals are reset. You can be confident about accuracy: our workshop uses modern equipment that identifies problems in time and lets us recommend how to solve them. Your safety and the uninterrupted running of your car come first. As for the price of diagnostics, our pricing is completely transparent, though it can vary from case to case.
Advantages of computer diagnostics:
- Accurate, fast checking of the electronic systems.
- Fault analysis across every control unit.
- Better overall safety when driving the car.
- Time and money saved on repairs, because nothing is done blindly.
