The turbo pressure control solenoid & the egr control valve & the exhaust gas cooler solenoid share the same 12v feed via main engine control relay but use different earth paths. turbo pressure earth ecu pin no b29 Egr valve earth pin no a13 & exhaust gas cooler earth ecu pin no

Sounds like a split or blown off charge air system hose or split intercooler.
