What's wrong with your car?
Choose the system the problem sits in and see the symptoms, the likely causes and the measurements we take.
EGR
Soot build-up, valve problems and EGR flow faults.
DPF
Loading, regeneration and differential pressure problems.
AdBlue / SCR
Warnings, countdown, injector and crystallisation.
NOx Sensor
Efficiency calculation, upstream / downstream difference.
Oxygen / Lambda Sensor
Mixture control and checks before replacing the sensor.
Catalytic Converter
Is the efficiency code really the catalyst?
Turbo / Boost
Requested versus actual boost pressure.
Fuel System
Pressure, injector corrections and hard starting.
Browse by symptom
The same symptom can come from more than one system. For the right fix, the source of the fault has to be confirmed with live data and measurement.
Engine warning lightMore than one system
The light only tells you that something has been logged. Which system it concerns is only clear once the fault memory and live data have been read.
Loss of pullTurbo · EGR · DPF · Fuel
Power loss can come from the air side, the exhaust side or the fuel side. Without measuring under load, no one can say which.
Misfire / rough runningIgnition · Fuel · Air
Ignition, fuel and air are assessed together. Without cylinder-by-cylinder measurement, no single part can be blamed.
High fuel consumptionMixture · Sensor · Fuel
Rising consumption can come from fuel trim, from a drifting sensor, or from a mechanical cause adding friction or drag.
Black smokeAir · Fuel · EGR · Turbo
Black smoke means incomplete combustion. The source can be the air side, the fuel side or recirculated exhaust gas.
White smokeFuel · Engine temperature · Mechanical check
White smoke can be condensation on a cold engine, or it can be the sign of a mechanical problem. Measurement and a mechanical check decide which.
Blue smokeOil consumption · Turbo · Engine mechanics
Blue smoke means oil is getting into the combustion chamber. The source can be the turbo side or the engine mechanics; a mechanical check is needed.
Regeneration problemDPF
A regeneration that never completes may not be the filter at all, but another fault that prevents the conditions for regeneration.
AdBlue warning / countdownAdBlue / SCR
The warning does not come from a single part. Fluid, pressure, dosing and NOx efficiency are each measured separately.
