5.2. Modifications and tuning beyond spec

  • Any modification to the turbocharger, its actuator, the internal components, housings, or the wastegate after delivery;
  • ECU tuning or software mapping that exceeds the safe operating parameters of the specific Product (maximum boost, maximum shaft speed, maximum EGT for the given wheel/housing combination);
  • Use of water-methanol, nitrous oxide, or other chemical power-adders at levels or with fuel strategies that exceed the Product’s rated capacity;
  • Combining the Product with other aftermarket components that cause it to exceed its designed operating envelope.

  • Use in vehicles fitted with launch control, anti-lag, or rolling-anti-lag systems not approved by us in writing for that specific Product.

5.4. External damage and force majeure

  • Physical damage caused by accident, impact, collision, fire, flood, water ingress, or other external events;
  • Foreign object damage (FOD) – debris from the engine, manifold, exhaust, or air intake reaching the compressor or turbine wheel;
  • Damage from corrosion, rust, electrolysis, or exposure to road salt not typical of ordinary road use;
  • Overspeed caused by boost creep, boost leaks, wastegate malfunction, or abnormal operating conditions.

5.5. Cosmetic and normal wear

  • Paint or coating discoloration from heat;
  • Heat-shield discoloration;
  • Gaskets, seals, O-rings, banjo bolts (consumables);
  • Minor shaft play within manufacturer spec;

  • Products that have been opened, disassembled, or serviced by anyone other than us or a workshop we have authorised in writing;
  • Claims submitted after the Warranty Period has expired.

6. Your obligations as the owner

To keep the warranty valid:

  1. Install the Product (or have it installed) in accordance with the installation instructions supplied with the Product and with the vehicle manufacturer’s service manual.
  2. Use the correct oil grade and quality, and observe the oil change intervals.
  3. Inspect and clean the oil feed and return lines; replace any pipes that are contaminated, damaged, or showing internal restrictions.
  4. Use fuel of the octane rating and quality required for the power level you are running.
  5. Keep maintenance records (oil change dates, mileage, service receipts) and provide them on request in the event of a warranty claim.
  6. Address any drivability issues (check-engine lights, boost leaks, smoke, unusual noises) immediately. Continued operation of a faulty vehicle will void the warranty.
  7. Do not exceed the rated operating envelope of the Product.

7. How to make a warranty claim

Step-by-step:

  1. Stop using the vehicle as soon as you notice a problem.
  2. Email contact@performanceturbo.eu with:
    • your order number,
    • the date of installation,
    • current mileage/hours,
    • installer’s name and workshop,
    • a description of the symptoms,
    • photographs and, where relevant, a short video (shaft play, smoke, oil in the intake, etc.),
    • copies of service records, particularly recent oil changes,
    • ECU / diagnostic readout if available (fault codes, datalogs).
  3. We will respond within 3 business days with either (a) a Return Merchandise Authorisation (RMA) number to send the Product back to us for inspection, or (b) a request for additional information.
  4. On receipt of the Product, we will perform an inspection and, if necessary, a teardown. You will receive an inspection report within 10 business days of our receipt of the Product.
  5. If the claim is approved, we will, at our option, repair, replace, or refund the Product.
  6. If the claim is rejected (e.g., the failure was caused by oil starvation, FOD, or tuning), we will provide a written explanation with photographs. You may then choose to (i) have the Product returned to you (at your cost), (ii) have us destroy it, or (iii) have us repair it at your cost per a quotation we provide.

8. Inspection fee

If the claim is rejected because the failure is demonstrably excluded under section 5, we may charge a reasonable inspection fee of up to [€100] (EUR 100). We will tell you the amount before performing teardown.

No inspection fee is charged for approved claims.

10. No extension of warranty

Repair or replacement of a Product does not extend the original Warranty Period.

11. Statutory rights (Consumers)

This commercial warranty does not affect your statutory rights as a Consumer. In particular:

  • EU / EEA / Polish Consumers are entitled to the statutory conformity guarantee of at least 2 years under Directive (EU) 2019/771 and, in Poland, the rękojmia under the Civil Code. This statutory guarantee is independent of and additional to our commercial warranty. If the Product is non-conforming, you may claim repair, replacement, price reduction, or – in certain cases – rescission of the contract, directly from us (Article 43a et seq. of the Polish Act on Consumer Rights).
  • UK Consumers benefit from the Consumer Rights Act 2015.
  • Consumers in the United States retain all rights under the Magnuson-Moss Warranty Act and applicable state laws. Nothing in this policy excludes or limits any implied warranty that cannot be excluded or limited under applicable state law. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the limitations above may not apply to you.
  • Consumers in other jurisdictions retain all rights they have under their national consumer-protection laws.

The duration of any implied warranty that cannot be disclaimed is limited to the duration of this commercial warranty to the extent permitted by applicable law.
