If you're wondering about the warranty that comes with a reconditioned gearbox or engine in 2026 — how long it lasts, exactly what it covers, and whether reconditioned, new or second-hand is the better choice — these are entirely reasonable questions, and the answers will have a direct bearing on your peace of mind. EDEN BOITES sets out the real rules here, plainly and honestly, to help you make the most informed decision possible.
Reconditioned, New or Second-Hand: Which Offers the Best Warranty in Practice?
Comparing a new, reconditioned and second-hand part is about far more than the sticker price. It comes down to long-term reliability, traceability of the work carried out, and the robustness of the warranty on offer. Here is a straightforward assessment of all three options.
New OEM Parts: The Gold Standard… At What Cost?
A new gearbox or engine ordered as a genuine manufacturer part has the advantage of a contractually defined parts warranty, though this is generally time-limited according to the manufacturer's own terms. However, for a vehicle more than five or six years old, the cost is often prohibitive: the saving achieved with a reconditioned part can run to several thousand pounds compared with the new OEM price. For many owners, the ratio of the vehicle's residual value to the cost of the repair simply makes buying new an irrational choice.
Second-Hand: The Illusion of a Bargain
A second-hand gearbox or engine from a breaker's yard carries a significant risk: you have no way of knowing what has happened inside. The mileage is unknown or unverifiable, internal wear is invisible to the naked eye, and any warranty offered — when one exists at all — is rarely worth the paper it's written on. If it fails quickly, you will have lost the cost of the part and the labour to fit it. Second-hand may look cheaper to buy; it can prove far more expensive over twelve months.
Professional Reconditioned: The Right Balance
A part reconditioned by a specialist such as EDEN BOITES is fully stripped down, inspected, and worn components are replaced to precise standards. This is not dressed-up second-hand stock: it is a documented technical overhaul. The warranty that comes with it — up to 24 months on the part at EDEN BOITES — is no small thing: it reflects the reconditioner's confidence in its own work. That is precisely what a second-hand part can never offer.
Professional reconditioned parts combine what second-hand cannot provide (traceability, a genuine warranty) with what new OEM parts do not always allow (a sensible budget for a vehicle more than five years old).
What Exactly Does the Warranty on a Reconditioned Gearbox or Engine Cover?
The warranty offered by EDEN BOITES applies to the part itself — up to 24 months on the part. It is important to understand what this means in practice, so there are no unpleasant surprises.
What the Warranty Covers
The parts warranty covers defects originating from the reconditioning process itself: a failing internal component, inadequate sealing, or a mechanical fault directly attributable to the work carried out. If the reconditioned part exhibits a fault inherent to its overhaul, EDEN BOITES accepts responsibility for the duration of the warranty period.
What the Warranty Does Not Cover
The warranty does not apply in cases of incorrect fitting, improper use, unsuitable fluids, or causes external to the part itself. This is why EDEN BOITES consistently recommends having the part fitted by a qualified professional and strictly following the manufacturer's technical specifications for oils, torque settings, and any electronic initialisation procedures required.
The Warranty Period: What Does "Up to 24 Months" Actually Mean?
The phrase "up to 24 months" means that the actual duration depends on the product, the sales arrangement, and the conditions specified at the time of order. This ceiling is significant within the reconditioning sector, where many suppliers limit their warranty to just a few months. EDEN BOITES takes a premium position here, consistent with its overall approach: if we are confident in our reconditioning, we stand behind it for the long term.
Exchange or Rebuild of Your Own Part: Two Approaches, Two Different Rationales
EDEN BOITES offers two distinct sales arrangements, and the choice between them has a direct impact on how your warranty and lead time are managed.
Exchange
You receive a reconditioned part ready to fit, and you return your old unit (known as the exchange core). This return is mandatory and governed by the terms of the contract. This is the fastest way to get your vehicle back on the road, as the part is already available.
Rebuild of Your Own Part
You send your own gearbox or engine to EDEN BOITES, who strip it down, fully recondition it, and return it to you. There is no exchange and no replacement core: it is your original part that is brought back to as-new condition. This option is particularly suited to rare vehicles, uncommon engine configurations, or customers who wish to retain their original part for historical or administrative reasons.
Key Checks Before Buying a Reconditioned Gearbox or Engine
Verify the Exact Match with Your Vehicle
A gearbox or engine — even one reconditioned by a specialist — must be a precise match for your engine configuration, engine code, and the electronic setup of your vehicle. Providing a VIN number and gearbox number from the outset allows EDEN BOITES to confirm compatibility before any commitment is made.
For DSG or Dual-Clutch Gearboxes
DSG and dual-clutch gearboxes reconditioned by EDEN BOITES are supplied without the mechatronic unit but with a new dual-clutch assembly. The mechatronic unit — a specific electronic and hydraulic component — is never included and must be dealt with separately. This is a fundamental technical point to factor into your budget and your diagnostic before placing an order.
For Engines
Reconditioned engines supplied by EDEN BOITES are sold as bare engines. Ancillary components (timing, turbo, injection system, alternator, etc.) are not included and vary according to each individual quote. This clarity avoids any confusion when the part is received.
Payment and Flexible Options
EDEN BOITES offers the option to pay in up to 10 instalments, making it easier to access a quality part without compromise. The exact terms are confirmed at the time of order.

| Flexible payment | Option to pay in instalments | Up to 10 instalments |
FAQ — Your Questions About Warranties and Choosing a Reconditioned Part
- Is the warranty on a reconditioned part legally regulated in France in 2026?
- Yes. In France, any sale of a part between a trader and a private customer is subject to the statutory guarantee of conformity (Consumer Code). This guarantee applies regardless of any commercial warranty offered by the seller. EDEN BOITES's commercial warranty — up to 24 months on the part — supplements this statutory baseline and reflects the supplier's quality commitment to its reconditioning work.
- Can the warranty be claimed if the part was fitted incorrectly?
- No. The parts warranty covers defects attributable to the reconditioning process itself, not fitting errors or damage caused during installation. This is why having the part fitted by a qualified professional is essential. If there is any doubt about the cause of a failure, a precise diagnostic will determine whether the fault originates within the part or from an external cause.
- Why is a reconditioned part so much cheaper than a new OEM part?
- Because components that are still serviceable are retained, and only worn or faulty elements are replaced. The production cost is therefore lower than that of a part manufactured entirely from new. This does not mean reconditioning is a cut-price solution: it is an economical and rational approach, particularly for vehicles more than five or six years old whose residual value does not justify the cost of a new OEM part.
- What is an exchange and how does it differ from a rebuild?
- An exchange means you receive a reconditioned part ready to fit and return your old unit (the exchange core is mandatory). A rebuild means you send your own part to EDEN BOITES, who reconditions it and returns it to you. No exchange, no replacement core: it is your own part that is brought back up to standard. The choice depends on product availability and your individual situation.
- Is my DSG gearbox supplied with the mechatronic unit?
- No. DSG and dual-clutch gearboxes reconditioned by EDEN BOITES are supplied without the mechatronic unit, but with a new dual-clutch assembly. The mechatronic unit is a specific electronic and hydraulic component that must be dealt with separately. This point is always made clear at the quoting stage to avoid any confusion.
- Is the reconditioned engine supplied with its ancillaries (turbo, timing, alternator)?
- No. Reconditioned engines supplied by EDEN BOITES are sold as bare engines. Accessories and ancillary components vary according to each individual situation and are specified on the quote. This transparency avoids any disappointment on receipt and allows the full cost of the job to be budgeted accurately.
- How can I be sure the part is compatible with my vehicle before ordering?
- The most reliable method is to provide your VIN (chassis number), your engine code, and, where possible, your gearbox number. This information allows EDEN BOITES to confirm exact compatibility before any commitment is made. An online quote is the best starting point for carrying out this check without any risk.
- Can I pay in instalments for a reconditioned gearbox or engine?
- Yes. EDEN BOITES offers the option to pay in up to 10 instalments. The precise terms are set out at the time of order. This option makes a professional-quality part accessible without having to find the full amount in one go.
