Strip and Diagnose Service.

We always recommend finding out why your turbo has failed.

There are many ways a turbocharger fails. Turbos fail for a reason. Always ensure you find the underlying cause for the failure before fitting a new one.

If your turbo has failed, we can strip and assess it. This will give a good indication as to why it failed and how to ensure it doesn’t happen again.

Following a strip and assess, when you order a repair or replacement turbo we will waive our strip and assess fee. We do this because we see diagnosing your turbo failure as vital for the success of your new turbo.
