Hi, I was going back to the home and push the throttle and nothing.. my turbo just got cut out.. when I get home I turn off the car and turn on.
An engine light goes on and I try to clear it and now it's not showing the engine light but making same limp mode.. I can drive 20min with turbo or 1min and it's not working.

All code what i get :

P0405
P0472
P149A
P155D

clean the EGR but nothing and event change the pressure exhaust gas sensor

These codes are probably electrical in nature. They are loosely related to fueling sensors and their wiring. There need to be tests done on these sensors and valves that you need good equipment for. If it were mine, it would be headed for the shop.

I didn't know they had an EGR valve, but clearly they do. I'd check to make sure it's actually actuating when it's running, Make sure the vac line isn't leaking and works, the elect plug is ok and works. Assuming it has both vac and elect. Since you get the electrical codes I'd suspect the plug or fuse, or maybe the elect part of the valve itself. I'm a believer in smacking parts if they aren't working, electrical or mechanical, so if it were mine, and it otherwise check out, I'd smack that EGR valve. I assume the valve and electrical parts are all one "part"? Meaning you can't buy just the elect part?
I had a CLK320 that gave me an egr code, but the egr worked fine. Had to sell it as a parts car because in California you can't sell a car without a smog and that egr code = an automatic failed smog. Thanks MB and Calif.
