Hello , thanks for your question in the autoaid Community.
Your described fault Code means:
TURBO/COMPRESSOR, BOOST PRESSURE CONTROL VALVE-CIRCUIT, SIGNAL TOO LOW / SHORT CIRCUIT TO GROUND
You need a second person to check the following:
Look at the Engine for the Turbocharger and then another person should take ignition on.
After this the boost pressure valve should turn a little bit.
Then you have to look under the turbocharger, there is an intake channel valve, this should be dry, but i think there is very oily and this is flooded. This part may be the problem, because more parts hang on this plus and ground points.
For this repair, the turbocharger must be build off.
Look also inside the turbocharger, of the intake compressor side is faulty. Maybe there is something flying inside.
Then the Turbocharger is faulty and must renewed.
Attention: The red seal at the Turbo intake must be new, because this will be leaking.
