Need some help

[Andy the Druid]

Greetings all. Slight problem my Vito 639cdi 2009. Had a p0069 fault. Barometric pressure sensor so I replaced maf map and boost sensor. Problem still remains. Goes into limp mode when engine drops to idle speed. Had it tested on a star. And it showed 800mb at the ecu. But that was as much as the mechanic told me any help would be great. Plus egr has been deleted but still shows open 4.2% in live data

If this were my problem I would probably start by returning it to factory spec, was it running ok before the EGR delete ?

Eve delete was done after the problem started. Cheers for your input
