A technical inspection checks whether a vehicle meets essential safety and environmental requirements. Yet it often becomes an unpleasant surprise: the car drives every day, no obvious warning is visible, but the inspection identifies brake imbalance, suspension wear, lighting faults or fluid leaks.
Preparing for inspection is not about hiding defects or forcing an unsafe car through the test. The purpose is to identify real problems in advance and correct issues that affect safety, reliability and legal road use.
In brief: what to check
- all exterior lights and headlamp alignment;
- tyre condition, tread and pressure;
- braking performance and imbalance;
- suspension, steering components and wheel bearings;
- oil, coolant and other fluid leaks;
- windscreen, wipers and washer system;
- seat belts, mirrors and horn;
- dashboard warning lights;
- exhaust condition and unusual smoke;
- number plate mounting and readable vehicle identification.
1. Lighting
Check dipped and main beams, indicators, brake lights, fog lights, reversing lights and number plate illumination. A failed bulb may look minor, but it can still cause an inspection issue.
It is also important that headlights are correctly aligned. Poor alignment may dazzle other drivers or provide insufficient road illumination. If a headlight was replaced, the car was repaired after an accident or the beam pattern looks uneven, alignment should be checked.
2. Tyres and wheels
Uneven wear may indicate poor alignment, worn suspension, weak dampers or other mechanical issues.
- sufficient tread depth;
- cracks, bulges or damaged sidewalls;
- compatible tyres on the same axle;
- visibly correct pressure;
- secure wheel mounting;
- excessive or uneven wear.
3. Brakes
A driver may not notice that one side brakes less effectively. An inspection brake tester will. Before the test, assess pad and disc condition, whether the car pulls to one side, vibration under braking, parking brake operation, caliper and guide movement, brake fluid level and visible leaks.
Squeaking alone does not always mean a critical fault, but grinding noise, vibration or pulling to one side should never be ignored.
4. Suspension and steering
Suspension faults often develop slowly. Drivers become used to knocking, looseness or instability and start treating it as normal behaviour. A workshop inspection should cover ball joints, track rods and ends, bushings, shock absorbers and springs, wheel bearings, CV boots, steering play and unsafe corrosion or damaged mounting points.
If the car wanders, knocks over bumps, the steering does not return smoothly or tyres wear unevenly, inspection should not be delayed.
5. Fluid leaks
A stain under the car is not a diagnosis, but it is a warning. The fluid may be engine oil, coolant, power steering fluid, brake fluid, transmission oil or harmless air-conditioning condensation. The important questions: which fluid is leaking, from where, whether the leak is active, whether the level has fallen and whether safety or other components are affected.
Cleaning the engine before inspection does not repair the cause.
6. Warning lights and computer diagnostics
If the engine, ABS, airbag, stability control or another warning light is on, deleting the fault code does not repair the car. Some codes return after a short drive, while others indicate a genuine safety-system problem.
Computer diagnostics can help read fault codes, review live data, distinguish an old or intermittent code from an active fault and plan further electrical or mechanical inspection. A diagnostic scanner is not a magic device that automatically identifies the part to replace – its results must be interpreted together with symptoms and physical inspection.
7. Windscreen, wipers and visibility
Check that windscreen damage does not obstruct visibility, wipers clean correctly and the washer system works. Mirrors, their mounting and their condition also matter.
8. Exhaust and smoke
Excessive noise, leakage, fuel smell or unusual smoke may indicate problems with combustion, turbocharger, injectors, EGR, particulate filter or exhaust components.
A short high-rev drive is not a universal cure. If the car smokes, lacks power or regenerates the particulate filter too frequently, diagnosis is required.
Common mistakes
- Checking only bulbs and ignoring brakes or suspension.
- Deleting fault codes without repairing the cause.
- Ignoring fluid leaks.
- Arriving with damaged or unsuitable tyres.
- Leaving all work until the last day.
- Choosing a temporary low-cost fix for a safety-related problem.
What does a workshop pre-check provide?
A pre-inspection check cannot promise that no issue will be found during the official test. It can, however, identify visible and measurable faults, reduce avoidable repeat visits and allow repairs to be planned.
At Hot Deals Garage, we can inspect the main risk areas, perform diagnostics and discuss the required work. Additional repairs must not be performed without agreement: scope and price should be approved with the client first. Book a pre-check at Kareivių g. 9B, Vilnius – phone +370 677 767 19 or servisas@hotdealsgarage.lt.
