Basically im phishing to see if the garage that repaired the intercooler fooked it up. Current problem is lack of power and clouds of black smoke. This isnt the first time its happened since it was changed either. we did have the mechanic look at it each time and error showed egr problems but he couldnt see anything wrong with the egrs so assumed they had cleared themselves

If it was an Intercooler or boost leak, it would smoke all the time

The EGRs are very guilty for sticking, and causing performance and smoke issues. They cannot be checked externally. They need removed and dismantled to check

Blank them as a first step, and go from there
