Turbo under boosting

Variable vanes inside the turbo closed
Inside the turbo, vanes open

We were asked by one of our customers to investigate a lack of power above 50 miles per hour – to all purposes they were experiencing the turbo under boosting.

We carried out a road test and confirmed the problem.

We then carried out full diagnosis with our fully up to date VAS 5051B.

Russell Automotive Centre is the ONLY Award Winning Specialist in London with same fully up to date diagnosis equipment as a main dealer.

We diagnosed an intermittently faulty turbo charger, we suspected the variable vanes inside the turbo were not moving smoothly and were becoming seized.

We removed the turbo and then disassembled it to confirm the problem.

Follow this link to our youtube channel to see the variable vanes moving. Russell Automotive’s youtube channel.

As we suspected, the variable vanes that were connected to the actuator linkage were not moving smoothly and were causing the lack of power.

A new turbo was fitted and the problem was completely rectified.
