Hello all, I am trying to get some help for my nephew as I can't drive down to San Marcos and his 05 Passat TDI 2.0 is in limp mode and the mechanic he took it to said it was EGR Valve (which I assume was wrong), but I bought hm one and he replaced it and now they are telling him it is the turbo. I assume they have not checked for vacuum leaks and don't even have a VCDS, so looking for a mechanic around the area.
