Default Problems after installing jb4 - 12-03-2021, 12:16 AM

After installing jb4 on b46 engine, if EWG connector is installed, warning light is generated. electrical wastegate, position sensor, electric: short circuit to plus
Reduced power mode
If I remove the EWG connector, it's OK.
What could be the problem?

Not all B48 models support the EWG connection, and it's usually not needed for B48 unless you're running a larger turbo, so I'd just leave it disconnected if you're having an issue with it.

They said that the B48 engine does not support EWG connection, but my car is a b46 engine. Are B46 and B48 engines the same?
