the egr and the pipe that's coming off it from the exhaust side could be clogged with carbon deposits. a screw driver and a some brake cleaner will usually do the trick. you can try using some seafoam and see if that'll do the job but if you've got buildup/blockage enough to trip the check engine light, I'd take a screwdriver and brake cleaner to the pipe and the innards of the egr where it meets up to the intake
