Frequently Asked Questions
Why is there no boost pressure?
No boost pressure typically means the turbocharger is not spinning properly. This can be due to a failed turbo, a massive boost leak that prevents pressure buildup, or a stuck wastegate held open.
Can I drive without turbo boost?
The engine will still run on naturally aspirated power, but performance will be severely reduced. Many vehicles will enter limp mode. Drive only short distances to a repair shop.
How expensive is a turbocharger replacement?
A new turbocharger typically costs $500 to $1500 for the part, with labor adding $500 to $1000 depending on the vehicle. Some remanufactured units are available at lower cost.

-
Check for boost pressure with a boost gauge or scan tool during acceleration
-
Inspect all intercooler piping, hoses, and clamps for leaks
-
Spin the turbo compressor wheel by hand -- check for free rotation and play
-
Inspect the wastegate actuator for proper operation
-
Check for exhaust restrictions such as a clogged catalytic converter
