Intake Air System leak If car was serviced check your air cleaner for all connections they may have left a vent hose off

code p3081 refers to engine temperature too low===causes--allow engine to warm up---cooling system fault
I would check for a thermostat stuck open

code p0322 refers to crank shaft position (CKP) sensor/engine speed (RPM) sensor--no signal===causes--wiring---CKP/RPM sensor---ECM

Run a small propane bottle with a rubber hose to areas to find leak. May show up only when engine hot. Engine rpm should increase rpm at source of intake vacuum leak

The code is for an intake leak, not just the EGR valve.
In most cases the leak is the hose to the valve cover or one of the hoses to one of the sensors is damaged.
Check the hoses, and if you replace anything make sure you disconnect the battery to clear the memory of the computer.

use silicon spray,a small area at a time,to localise the noise,do it in a very quiet area(no kids)sorry had to get that in....

All of those codes will come up as probable cause. The hand helds that auto stores use are not accurate. You need a certified mechanic with a Genesis , Snap On or a Mac scanner or the dealership. The actual problem could be causing any of these codes.

it should be near a coolant hose or your water pump

it's expensive but not as expensive as replacing the engine... was the oil pressure checked ?

The dealer gets there build info via computer link to the manufacturer data base for paticular car, you can be 99.99% it is correct.
