Warranty

• All Turbochargers carry a 12-month warranty from the date of supply, provided that the turbo has been fitted and serviced in accordance with the vehicle manufacturers fitting instructions.
• autosupply does not regard any warranty period above 12 months to be of benefit to our customers. Turbochargers incorrectly built will fail long before 12 months from fitting.
• Failure after this period will invariably be caused not by faulty manufacture, but by circumstances outside the control of the original turbo build.

If you wish to make a claim, we will carry out a thorough examination of all components before a decision is made as to the validity of a warranty claim.

On receipt of any returned turbocharger units, turbo engineers will dismantle and inspect the turbocharger and determine the cause of failure. We will then notify the customer of the results of the fault diagnosis. If it is deemed that the turbocharger has not been fitted correctly or some modification has been carried out by the customer or the turbocharger has been dismantled by a third party the turbo will not be covered under the warranty.

• Warranty which does not cover any labour costs incurred by the customer for fitting or removal.
• No damages for distress, loss of earnings or costs incurred for independent advice are covered by the warranty.
• Warranty does not cover any turbocharger supplied if it is modified in any way or fitted to any other vehicle than that which it was supplied for. Any alteration to the vehicles ECU system, chipping or re-mapping will void the warranty.
