What Does “Voiding a Warranty” Actually Mean?
What Does “Voiding a Warranty” Actually Mean is really important to know in detail before you start ECU Remapping and its effects. In Simple words, vehicle warranty is a legal aggrement between costumer and manufacturer which legally says that if your car suffers from any problem/fault, manufacturer is responsible to repair or replace that part/component under warranty till warranty lasts if terms and conditions of that legal agreement are followed by costumer.
Now a days, most of the new vehicles comes with a standard warranty of 2/3 years that covers engine, transmission, electronics and other key systems if anything got damaged or stops working. Warranty void are of 2 type: Full Void and Partial Void.
- Full Warranty Void: Full Warranty Void means complete/entire warranty of vehicle is cancelled. It is very rare and only done if major illegal modifications are done. After this, if anything goes damage or stop working, company will not cover anything in warranty.
- Partial Warranty Void: Partial Warranty Void means warranty by manufacturer cancelled for any specific thing, part or component. Often void because of modification like ECU Remap is linked to failure of specific part/component.
Dealership does not have any right to void your warranty. Manufacturer is the real authority to take decisions on warranty void. Only manufacturer has this authority on this basis of legal agreement signed at the time of purchase that if any aftermarket modification found as a reason for any thing to be damaged or faulty, then manufacturer can partially or Fully void your vehicle warranty on the basis of your modification done. If found stock, they will cover everything.
Does ECU Remap Void Warranty? (The Real Answer)
Does ECU Remap Void warranty? Definately YES, if manufacturers got to know about any modification like ECU Remap/Tuning, any performance mod upgrade like turbo upgrade/intercooler upgrade, then manufacturers can definately void your warranty. But not always — it totally depends on how it’s done, and who detects your remap.
HOW IT’S DONE:
- If ECU Remap is done by connecting tuning device via OBD Port and ECU is not opened physically. Some tuner also offers remaps that are harder to detect: reversible maps or invisible remaps (back to stock) within very few time. It can prevent your warranty void.
- But, if the ECU is opened physically and changes made are aggressive (vast change in values) or poorly documented. In this case, manufacturers can easily detect your Remap through diagnostics/formal checkup.
WHO DETECTS IT?
- Some service centers just do basic checks and may not go deep that an ECU Remap can be recognised. So, the warranty doesn’t void and remains unaffected.
- Authorised Service Centre or OEMs (Original Equipment Manufacturers) can detect checksum changes or flash counters. If they detect this, it can void your vehicle’s warranty.
NOTE: To save your warranty, always remember that if Authorised Service Center asks to check your car through connecting laptop and says that it will completely scan your car to make sure everything is fine. Never allow them for this. (They don’t have any idea of your remap, they only say to increase your bill and to earn more money, but if you say YES, and they detect, it might void your warranty)
They will always ask you before connecting a laptop because they charge extra for scanning your car. Don’t allow them. It is only needed when your car behaves uneven or shows any light in meter like check engine light. If you got any of these signals, always prefer your tuner to check your vehicle and detect what’s the problem.
4 Myths Busted About: Does ECU Remap void Warranty?
4 Most Famous Myths about Remaps and Warranty with a Big Question that Does ECU Remap Void Warranty:
Myth #1: Dealerships will always know if you’ve remapped
No, Dealerships and Manufacturers does not have any technology like that if you ever try to connect your vehicle ECU or modify it then they will get any notification alert. Dealerships can’t know if your car is remapped or not – until or unless they connect Laptop with your car, and it will never happen without your permission.
They can find out, but only if they connect their laptop to your car’s ECU and check for it. This is usually done during engine-related warranty claims, not during regular service.
So, If your car shows any check engine light or any error code, rather than running to authorised dealer, make your vehicle check to your car tuner for safer side and unnecessary scans that might risk your warranty.
Myth #2: Even a Stage 1 ECU Remap Void Warranty
NO, A Remap does not void your entire warranty. If detected, only powertrain-related parts (Engine, ECU, Turbo & GearBox) are affected. Other things like AC, Lights, Suspension, Brakes, Music System, and features stays under warranty.
👉 Manufacturers can’t deny your warranty claim only if ECU Remap is detected. If they are unable to prove that Remap is a reason for damage caused which you are claiming in warranty, they can’t reject your claim. If they do so, you can follow legal procedure against them.
Manufacturers can only deny a claim if they can prove the remap caused the damage — as per the Magnuson-Moss Warranty Act (in the U.S.) and similar guidelines in other countries
Myth #3: Reverting Back to Stock Removes All Traces
NO, reverting your ECU Remap back t o stock does not removes all traces. Even if you flash your vehicle’s ECU back to stock, traces may remain inside ECU in form of Flash Counters, checksum changes, etc.
As told inside how it’s done in Heading: Does ECU Remap Void Warranty? (The Real Answer), Only few Tuners offers us invisible remaps with such tools that resets flash counters, checksum changes, and other counters. But, not all tuners do this.
So, Reverting Back to Stock does not removes all traces, it just lowers the risk of detection, not always makes it invisible. Only few tuners can do this.
Myth #4: You can claim warranty and hide the remap easily
If you claim warranty something that does not relate any combination/link with ECU Remap like AC not working, any lights, music system, or any electronics, then you don’t even want to hide your remap. You can get claim under warranty easily.
But, for engine, fuel system, turbo, etc. they often run scans and can detect your ECU Remap. You can’t hide the remap easily and they have right to deny your claim under warranty if they detect your ECU Remap.
I have told you above also that only few tuners offers invisible remaps and only they can hide your remap easily and you can claim anything under warranty regarding engine related issues.
