Ok! So I worked on the car yesterday, trying to figure out the whistling sound! i did a boost leak test and found out that a gasket that is between the pipe goes down from the turbo to the I C pipe, went bad. So I replaced it.... good no more whistling sound.... Re-did a boost leak test nothing is leaking air...
Went behind the T B to see the EGR valve to make sure no vaccum line popped off as the engine light is showing code P0403... but everything is intact... I reset the code turned on car drove it for a while, took it home shut it off, and then re-started Engine light back on, with the same code.... I dont know what else to do so please help me out!
Thanks

i see u said u went behind the Tb to see if the line was poped off. SO im assuming u did check under neath where the 2 line go into the egr right? If thats not it have you cleared this code from ur ecu as if u have had it b4? If you had this code b4 and fixed it and the car didnt reconize the code anymore the light will shut off but the code will stay in the memory of ur ecu u have to actually get an OBD scanner and erase this code for it to be out of ur ecu completly or it will show back up over a period of time because like it said its in the memory of your ecu. Good luck! Also u out the gasket on the turbo outlet pipe did u put that vacum hose back on the pipe its a little hard to see but that will throw the code also! Again good luck!

 

where does the code pop out?

 

Thanks man for replying!
I found the problem yesterday, it was the sensor that has two vaccum lines that comes from the egr valve! It was craked so I replaced it and cleared the code, and now code is gone!

Thanks I really appreciated!
