At TDI Tuning, we understand that diesel tuning boxes are a big investment for many of our customers. The devices are intricate and technologically sophisticated, so product failures
will have a big impact on the everyday running of your vehicle. If you believe that your diesel tuning box isn't running as it should be and you suspect it's faulty in some respect,
we'll be more than happy to inspect and repair or replace the diesel tuning box as necessary under the terms of our handy three year warranty. To take advantage of this service, all
we'll ask you to do is contact us for a returns form, which you can then enclose within the return package.
