The EGR issue with the 2009 109 CDI Vito


Recommended Posts

Hello, the previous EGR was causing an engine management light code, therefore my mechanic just installed a new one.
The code returned after a short period of time with the new EGR installed 😞
He verified that the electrical connection was functioning properly.
Feel free to share any suggestions you may have.

It can be the ECU connection(s).
A live function test might reveal its operational status. Indeed, Star is capable of doing that.

If not, some diagnostic tools may detect an open cct problem.
