Frequently asked questions
Can an EGR fault on the Mercedes-Benz Vito be solved with software?
The valve and connections are checked first. Where suitable for the Mercedes-Benz Vito, the EGR software solution is applied to the ECU with the original software backed up; on most cars the work is done the same day.
How much power does the EGR job add on the Mercedes-Benz Vito?
The EGR job is not a power remap; no horsepower gain should be expected from it alone. Because the loss of pull and the reduced-power mode caused by a faulty EGR disappear, the vehicle returns to its factory output. If more power is wanted, a Stage 1 remap is applied separately.
What changes on the Mercedes-Benz Vito when the EGR is switched off?
Exhaust gas is no longer fed back to the intake; soot build-up in the intake manifold and valve stops, and EGR fault codes and the reduced-power mode end. Nitrogen oxide emissions rise, which is why the job is offered for uses permitted by the applicable regulations.
How do I recognise an EGR fault on the Mercedes-Benz Vito?
The engine warning light, an uneven idle, loss of pull, black smoke and higher fuel consumption are the most common signs. A definite diagnosis is made by reading the fault memory and the valve position values.
Is an EGR delete legal?
It is an intervention on emission hardware and is offered only for uses permitted by law (off-road, motorsport, export, fault diagnosis). Inspection and road compliance remain the owner's responsibility.
Is replacing the valve the better option?
Often yes, especially if the car will be used on the road. If the valve has failed, fitting a new one is the durable and compliant solution; we measure the condition and explain the options plainly.
Does carbon build-up stop?
Once exhaust gas no longer returns to the intake, soot accumulation drops noticeably; existing deposits still need mechanical cleaning.
Will the warning light go out?
EGR-related codes are switched off in a controlled way; if another fault exists the light stays on.
