Error Code PO403
Hi everyone,
I'm new to the forum. Recently picked up a 2003 SLK32 AMG. Have had fun driving it around.
Today, while driving. I drove a few miles to get coffee, came out (about 20 minutes later) and the car would not turn over. Cranked but would not start.
I read in the forums that others have had this similar problem. I waited about 15 minutes, tried again and the car started up, but the "check engine" light came on.
People in the forum stated they had similar problems and it was a faulty crankshaft sensor. However, other said don't start replacing things until you get the error codes read.
I checked, and the error code was PO403, which is a "Exhaust Gas Recirculation Circuit Malfunction."
Anyone had this issue and what to do?
I don't want to drive car anymore, just incase it won't start back up and I am left stranded.

I just went out to move my car.
Car started right up and NO CHECK ENGINE light on anymore.
Still concerned about why the car didn't start up and the error code.
Still looking for input if anyone else had this issue.
