Hi all I just had the pleasure of pulling a 2010 jetta engine out and replacing the engine. It was fairly un eventful and I didn't have much problem until I started the replacement motor. Ok the jetta I bought had a bad #3 cylinder failure and rod knock. I found a good low mileage motor from a salvage car with only 33k. The car has 64k. I put everything back together when I noticed the inner cooler had brown and green goo from the old motor. I replaced it and re looked at all the tubes and air lines. I had to replace the throttle control valve, not sure what it's official name is, cause the replacement motor's was broken at the plug. This happens when motors are shipped. Anyway get it all back together and cleared old codes. Started right up, topped off coolant and went for a drive. The check engine light came right on and the glow plug light kept flashing. I have reset to several times and sometimes it will do it when I turn off the key but then it's back. I've looked every hose, wire, bundle, plug and removed ALL the boost hoses, codes are all the same but I'm too tired to post them. I wonder if I need to do a calibration of the throttle valve ? Anyone? I did check the posts for this problem but I don' t believe the turbo is bad. I am going to check the actuator with a vac pump in the morning. Just wanted to vent thanks you all.
