Проверка реального пробега при покупке автомобиля: честно о том, что возможно
Скрученный пробег — одна из самых частых проблем при покупке авто с рук. Рассказываем, как проверяется реальный пробег по электронике, почему не на всех марках это просто и что стоит проверить до оплаты.
Video: A look at our work at AUTOLAB
We filmed a raw, unedited look at a day in the AUTOLAB workshop, showing exactly how our diagnostics and ECU tuning processes happen behind the scenes.
Car won't start: the story of a dead ECU
A client brought in a car that suddenly stopped responding to the key. We explain why sometimes the problem isn't mechanical, but rather in the car's brain.
Oxygen sensor: why your car is guzzling fuel and losing power
We break down a case where an oxygen sensor error leads to extra expenses and explain why replacing the part doesn't always solve the problem.
Automotive Ethernet: Why Diagnostics Are Getting More Complex
Modern vehicles are shifting to high-speed Ethernet networks, changing the rules of the game for electronics diagnostics and repair.
Keys and Immobilizer: When Your Car Stops Recognizing the Owner
We explain why your car might suddenly refuse to start and what to do if your key no longer unlocks the doors or ignites the engine.
Diesel ecology: why DPF, EGR, and AdBlue systems fail
We explain why exhaust emission control systems become a headache for owners and when it is time to visit the service center.
Adaptation and ECU: Why Your Car Doesn't Understand What You Want
We explain why a car needs adaptations and why it might perform worse after a simple repair.
Water-damaged ECU: A story of a rescue
A client arrived with a dashboard full of warning lights and a car that wouldn't start. Let's look at why moisture inside an ECU isn't a death sentence, but a job for a pro.
Car stalling while driving: A crankshaft sensor case study
Did your engine suddenly die right in the middle of the road? We break down a real-world case where the culprit turned out to be the crankshaft position sensor.
Why your scanner stopped seeing your new car: The era of CAN-FD and Ethernet
Modern vehicles are shifting to new communication protocols, rendering older equipment useless. We break down what has changed in diagnostics.
Keys and immobilizer: what to do if your car doesn't recognize the owner
We take a look at why a car stops recognizing its key and how to solve immobilizer issues without unnecessary expenses.
Экология дизеля на пальцах: DPF, EGR, AdBlue и почему они сдаются
Простыми словами о том, как взаимосвязаны сажевый фильтр, клапан EGR и мочевина, почему короткие поездки их убивают и что делать при первых сбоях.
Осциллограф в автодиагностике: как кардиограмма спасает от лишних замен
Обычный диагностический сканер показывает только жалобы блока управления, а осциллограф видит реальные физические процессы в проводке за доли миллисекунды.
NOx Sensor: Why Your Car Feels Sluggish and Whether to Replace It
We look into why the Check Engine light comes on due to the nitrogen oxide sensor and whether you can avoid an expensive replacement.
Parasitic Battery Drain: Why a Brand-New Battery Died Over the Weekend and How We Found the Culprit
A familiar story: the battery is brand new from the store, but come Monday morning, the car won't even unlock. We break down a real-world case of parasitic battery drain and explain why simply replacing the battery rarely fixes the problem.
CAN-FD and Automotive Ethernet: Why Old Scanners Can No Longer Read Modern Cars
Modern vehicles are shifting to high-speed CAN-FD and Automotive Ethernet data buses. We explain how they work and why a cheap ELM327 scanner is now obsolete.
Keys and the Immobilizer: Why the Car Won't Start and What Owners Should Do
A plain-English explanation of how your car talks to your key, what happens when you lose keys or replace electronic modules, and why a hardware store copy isn't enough.
Diesel Emissions Systems in Plain English: How DPF, EGR, and AdBlue Work and Why They Fail
Discover why modern diesels rely on complex emissions systems, why short city trips cause them to fail, and how to avoid costly repairs.
What Is Electronic System Adaptation and Why Repair Isn't Done Without It
After replacing a sensor or component, a car sometimes behaves strangely. We explain in plain English what the adaptation procedure is and why the ECU cannot read the mechanic's mind.
Car Stalls When Hot: A Real-World Case of Tracking Down a Hidden Fault
The engine starts up perfectly, but as soon as it warms up, the car suddenly dies right while driving. We break down a real diagnostic case from our workshop.
Stage 1 Chip Tuning: What Really Changes in the ECU Software
What actually changes in the engine software, how much performance it delivers, and why it is safer than it seems. Breaking it down with zero marketing fluff.
DPF Removal: Why It's Done and How to Do It Right
Why the diesel particulate filter gets clogged, what risks it poses, and how software DPF delete is done properly.
Immobilizer Not Recognizing Key: Why It Happens
Car not recognizing the key: a breakdown of common causes—from a dead key fob battery to desynchronized control modules.
