yes, from around 2018-2019 EMEA market got GPF filter.
read your error codes with diagnostic, warning message says nothing on cluster.

 

Warning says: Please repair the engine.
I have been to the service for two time, they just clear the code, no other solution at this moment.

 

The particle filter has to burn off the buildup so it needs some longer journeys to heat it up.

 

The problem is this is totally un-controlable, anyway, I will try.

 

There’s a module that controls it.
i just googled it

Yes, today I checked with service that the DTC code is ECM P0402-00.

 

Code: 0402

Definition:Exhaust Gas Recirculation A Flow Excessive Detected

Description:The EGR Valve Assembly contains an electric DC motor and gear box. An eccentric drive translates the gearbox output from a rotating motion (DC motor) to a linear stroke (output shaft). An internal return spring ensures that the valve returns back to its closed position as a fail safe.During initial opening of the EGR Valve, the PCM drives the PWM voltage high resulting in a high current draw. After the valve is fully opened the PCM voltage is reduced to maintain the EGR Valve position. This reduces the current draw and protects the DC motor from overheating.The PCM also applies a current in the closing direction to fulfill the required dynamic performance. This is done to slow down the closing speed of the shaft near the stop. This ensures that the valve does not close too fast causing the valve disk to be forced into the stop harshly which may damage the internal gearbox.

Cause:

• EGR VALVE STUCK OPEN
• EGR SYSTEM LEAK
• EGR VALVE ASSEMBLY

 

Update of this thread:
---The DTC code disappear after 2-days aggresive driving in manual mode(~100km).
I can shift DNA and S&S function is ok now.

 

I got today an Engine Light on. and P2453-00 error.
should I consider GPF filter issue too? or Look for the Differential Pressure sensor of GPF?

Stelvio 2021 - 37000miles (60k km)

 

Not sure about this DTC code failure cause, perhaps relate to the DPF differential pressure sensor and the oil pressure from the variable displacement pump. Suggest you to do a check from service.

 

I also have Gasoline, and GPF.
How long you drove till error went away? In distance.

I heard the same story for my error.
