I've seen my car goes into limp mode every time that there is a DPF regeneration.
Checking with MES during the failure I've seen while DPF is regeneraring the Boost pressure goes below 530 mbar.
I've changed the MAF since I got a message related to "Air Mass incongruent" but the problem is not solved. I've also changed the boost solenoid without success.
Does someone know what is the relation between DPF regeneration and the boost pressure?. I dont know how to solve this issue. I need you help.
Thanks

The problem is located at one of the metal pipes between DPF and sensor DPF. One of them is broken and the sensor is not working as expected.
