Knowledge base
Explained without
the jargon
What exactly does an inspector check? What do you do when your car fails the APK? And why does a cheap diagnostic readout miss your fault? Below we explain what we see in the workshop every day — in plain language, in Dutch, English and Polish.
APK: failed & preparation
Failed the APK? How to read the inspection report line by line
Rejection point, repair advisory, RDW spot check: what every line on the Dutch APK report means and what to do next.
Your car failed the APK — what happens next
From inspection report to re-test in six clear steps — including whether you may still drive and how to plan the repairs.
The Dutch APK report translated: every term explained in English
From goedgekeurd to fuseekogel: each term on the inspection report briefly explained, with the English translation next to it.
What exactly is APK preparation? (And what the inspector does)
Preparation and inspection are two different things. What we check and repair — and why it saves you a re-test.
The 10 most common APK failure points — and how we fix them
What do cars most often fail the Dutch APK on? The ten classics in a row, with the repair that goes with each.
APK expired: can you still drive and what do you do now?
The automatic register check, fines, insurance and the way back: what to arrange when the APK expiry date has already passed.
The APK re-inspection: how the deadlines work
There is no legal re-inspection deadline — but three dates do matter. How to plan repairs and the re-test smartly.
Rust and the APK: when is corrosion a rejection point?
Cosmetic rust doesn't fail — corrosion on load-bearing parts does. Where the inspector probes and how welding repairs work.
Lights and the APK: which LED bulbs are allowed and which are not?
Failure reason number one. What the inspector checks, how LED retrofits are treated and why headlight aim counts just as much.
The APK spot check: what it means and how much time it costs
The RDW audits the inspector, not your car. How the steekproef works, what can happen and why you don't need to do anything.

Diagnostics
OBD readout vs. brand-specific diagnostics: what is the difference?
A universal readout sees the engine. Factory diagnostics see the whole car. Explained by your garage in Tilburg.
Car diagnostics: what a mechanic sees on the screen
A fault code is a clue, not a conclusion. How a mechanic gets from code to cause.
Clearing fault codes is not a repair — here is what you lose
The code disappears, the problem does not. And the most important clue goes with it.
Adaptations and service resets — why the repair ends there
Fitting is step one. Coding, adaptation and resetting turn it into a finished repair.
Symptom & cause
Engine warning light on — can you keep driving?
Steady amber or flashing: the difference decides whether you drive on calmly or switch the engine off.
Dashboard warning lights: what each symbol means
Red means stop, amber means attention. All the important symbols with the right action.
Car won't start: battery, alternator or starter?
The sound when you turn the key tells you the cause. Four scenarios explained.
Car won't pull — limp mode, turbo or transmission?
Do the revs rise but the speed doesn't? Then you are looking in a completely different place.
Strange noise from your car — broken down by situation
Braking, cornering, over bumps or on a cold start: each moment points in a different direction.
Vibration when braking — discs, hubs or suspension?
Does the wheel shake or the pedal pulse? Where you feel it points to the cause.
Squealing brakes — when is it harmless and when not?
Morning rust squeals too. The difference is when it squeals and whether it goes away.
Blue, white or black exhaust smoke — what the colour reveals
Oil, coolant or a rich mixture: the colour points the way, the timing tells the rest.
Particulate filter not regenerating — four causes in order
From short trips to a filter that really is full: how regeneration works and where it goes wrong.
Coolant disappearing with no visible leak — where does it go?
Evaporating from a small leak, past the head gasket, into the heater matrix or out through the cap.
Air-con blowing warm air — three causes in order
Too little refrigerant, a compressor that won't engage or an electrical fault. How to rule them out.
Damp in the car and misted windows — where does it come from?
Blocked drains, a failed seal or coolant: each source has its own signature.
Power steering heavy or uneven — where does it come from?
Hydraulic or electric: the type of system determines which causes come into play.
Strange electrical faults — often a single bad earth
Several illogical faults at once rarely means several defects. Usually it is the earth connection.
