Diagnostics
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.

Diagnostic work. When thorough, step-by-step diagnostics are needed: checking live data, measurements, a test drive, examining components or partial dismantling.
Quick checks
For simple situations where the problem can be assessed visually, with a short check or by lifting the car on the lift.
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 does not always mean that the part mentioned in the code description should be replaced.
How we inspect
Some faults only show up in certain conditions – and they cannot always be brought out in a first short check.
Help us
During diagnostics we check electrical causes related to the specific problem.
Inspection faults
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.
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.
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.
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.
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.

Based on the description of the symptom, we estimate how much time the diagnostics will take.
