2008 E320 Diesel NO Boost
2008 E320 with 140K miles. Turbo went south and dealer wanted almost $3000 to repair. I had turbo rebuilt, and then I changed all fluids and checked everything and then when I put everything back together the car ran great for about 100 miles then Boost went away. Took to dealer and they said the hoses on intercooler were faulty and wanted over $900.00 in labor alone to change out so bought them and replaced myself. Double checked everything again and car still has no boost. idles fine, Can anyone give me thoughts and direction? Thanks......

320Diesel DTC P0299 code
2008 320 Diesel I pulled the DTC Code P0299.
I checked the air intake, double checked by actually taking it apart and checking to make sure all connections were good and did the same with the Intercooler hoses making sure they were tight and everything looks good. What's next? This turbo has about 100 miles on it since installed. When I took the turbo in to be rebuilt I did not take the actuator (guess it controls the wastegate) A friend said I should have taken it in to be checked??

That's not a bad idea, it'll tell you the condition of the actuator itself. The P0299 DTC code refers to a condition where the PCM/ECM (powertrain/engine control module) has detected that the bank "A" or single turbocharger or supercharger is not providing a normal amount of boost.
