When mine failed a couple of months ago I got the following codes (but not PO299).
Powertrain Control Module Trouble Codes:
• P0403: ACTIVE - EGR "A" Control Circuit/Open
• P0046: STORED - Turbocharger/Supercharger Boost Control "A" Circuit Range/Performance
• P0234: STORED - Turbocharger/Supercharger "A" Overboost Condition
