Yes, used parts come with a warranty too
One of the most common myths about used car parts is that you are buying "a pig in a poke". That you have no protection, and if the part does not work, that is your problem. It simply is not true. At least not when you buy from professional sellers.
Serious scrapyards and used parts suppliers offer warranties on their products. Duration and terms vary, but a warranty does exist, and it can save you a lot of money and stress if something goes wrong.
Warranties on used parts come in different shapes: from 30 days to 12 months, from a straight refund to a replacement with the same part. Each one covers something specific, and your legal rights as a buyer apply regardless of what is written on the receipt. Knowledge is power, especially where your money is concerned.
Types of warranties on used parts
Warranties on used parts are not standardised the way they are on new products. Every seller has their own policy. But broadly, they fall into a few categories.
Functional warranty
This is the most common type. The seller guarantees that the part works correctly at the time of sale and for a set period afterwards. If the part does not work or stops working in that period, you have the right to a replacement or a refund.
Typical duration: 30 to 90 days for most parts. For engines and gearboxes, some sellers offer 6 or even 12 months.
Compatibility warranty
The seller guarantees that the part fits your car. If you provided an accurate VIN and got the wrong part, the seller is obliged to replace it or refund your money. This warranty is logical and most sellers offer it without being asked.
"As is" warranty (sold as seen)
Some sellers, especially private individuals, sell parts "as they are" with no warranty at all. That means you buy at your own risk. This is the riskiest option and should be avoided whenever possible.
Extended warranty
Some professional suppliers offer the option to buy an extended warranty for an extra fee. For example, the standard warranty is 30 days, but for another EUR 50 you can get 6 months. For expensive parts like engines, this can be a smart investment.
What a warranty usually covers (and what it does not)
This is where many buyers get caught out. A warranty on a used part is not the same as a warranty on a new product. Here are the differences.
What is usually covered
- Total failure of the part (the part does not work at all)
- Hidden defects that were not visible at the time of purchase
- Incompatibility with the car (if you provided an accurate VIN)
- The part does not match the description (different condition than stated)
What is usually NOT covered
- Normal wear - the part is used, and some wear is expected and acceptable
- Damage during installation - if the mechanic damages the part during fitting, that is not the seller's fault
- Incorrect installation - if the part is fitted improperly and that is why it does not work, the warranty does not cover it
- Corrosion and surface damage - visual defects that do not affect function
- Parts that have been modified after purchase - if you changed anything on the part, the warranty is void
How long should a warranty last?
Here are some sensible expectations by part type.
Engines
Minimum 30 days, ideally 3 to 6 months. Some premium suppliers offer 12 months on engines. Given the cost of an engine (EUR 500 to 1,500 used), a warranty of at least 3 months is a reasonable expectation.
Gearboxes
Similar to engines. Minimum 30 days, ideally 3 to 6 months. Automatic gearboxes should carry a longer warranty because they are more complex and more expensive to repair.
Alternators, starters, compressors
30 to 60 days is standard. These parts are relatively simple to test, so 30 days is usually enough for any problem to show up.
ECUs and electronics
30 to 60 days. Electronics tend to either work or not, so a fault shows up fast.
Body panels
A compatibility warranty (that the part fits) is standard. A condition warranty (no hidden corrosion or damage) varies from 7 to 30 days.
Your legal rights as a buyer
Regardless of what the seller's warranty terms say, as a buyer you have legal rights that protect you.
Consumer protection law
If you are buying from a legal entity (a registered company or sole trader), consumer protection law gives you the right to claim for material defects. That means if the part had a defect that was present at the time of sale (but may not have shown up immediately), you have the right to repair, replacement or a refund.
Important: this only applies when you buy from a legal entity, not from a private individual. Buying from a private seller on a classified site or Facebook does not fall under consumer protection law.
Right to make a claim
You have the right to make a claim on the product within 2 years of purchase for hidden defects that existed at the time of sale. But be aware: the burden of proof is on you. You have to show that the defect existed before purchase and did not arise through use. With used parts, this can be tricky.
Right to a working product
If you bought a part that does not match the description or is not functional, you have the right to request a replacement or a refund. The seller cannot say "well, it is used, what did you expect". Used does not mean broken.
How to make a claim on a used part properly
If you have a problem with a part you bought, here are the steps to take.
1. Document the problem
Take photos or a video of the problem. If you can, get the mechanic to write a short statement on what the problem is and whether it could have been caused by installation or is inherent to the part. This documentation is key to a successful claim.
2. Contact the seller as soon as possible
Do not wait. As soon as you notice the problem, reach out to the seller. The sooner, the better. Explain the issue, attach photos or video, and state what you want (replacement or refund).
3. Be polite but firm
Do not be aggressive, but do not let them brush you off either. State your claim clearly and reference the warranty or your legal rights. Most professional sellers will resolve the issue quickly because their reputation matters to them.
4. Keep the part until the claim is resolved
Do not throw away or modify the part until the claim is settled. The seller will probably want to inspect the part to determine the cause of the problem. If you have already binned it or given it to someone else, you have nothing to show.
5. If the seller will not cooperate
If the seller refuses your claim without a valid reason, you have several options. You can contact the relevant consumer protection authority, take the matter to a consumer disputes tribunal, or leave a negative review (often the most effective approach because sellers care about their online reputation).
Tips for maximum protection when buying
Here is how to protect yourself before a problem even comes up.
- Ask for a receipt - the receipt is your proof of purchase, and without it you have no basis for a claim
- Get the warranty terms in writing - ask for a written warranty or at least an email confirmation with clear terms. A verbal agreement is hard to prove
- Photograph the part on collection - document the condition of the part when you get it. If you later claim it was damaged, the photos serve as evidence
- Have the part fitted by a professional - amateur installation is the most common reason for warranty rejections. If you have an invoice for the work from a certified mechanic, your position is far stronger
- Buy from registered businesses - legal entities are required by law to give you protection. Private individuals are not. This is the most important tip in the whole article
- Use platforms with verification - when you send a request through PoDi, suppliers are vetted and have a review system that encourages them to do honest business
Warranty vs. price: is it worth paying more for a warranty?
This is a fair question. Sometimes you can find the same part from two sellers. One offers a 30-day warranty for EUR 150, the other has no warranty but costs EUR 100. What do you choose?
The answer depends on the part. For cheap parts (under EUR 50), the risk is small and you can accept buying without a warranty. But for more expensive parts (engine, gearbox, turbo, ECU), that EUR 50 difference is small change compared with the potential loss if the part does not work.
Think of it this way. You buy an engine for EUR 800. With a warranty it costs EUR 900. Without one, EUR 750. If the engine does not work and you have no warranty, you have lost EUR 750. Plus installation and removal costs. Plus a new engine you need to buy all over again. Total loss: EUR 1,500 or more. For an extra EUR 150 for the warranty, you bought peace of mind.
Questions you MUST ask before buying
Here is a list of questions you should ask any seller of used parts.
- How long is the warranty on this part?
- What does the warranty cover and what does it not cover?
- How do I make a claim? Who do I contact?
- Who pays for return shipping in case of a claim?
- Do I get a replacement part or a refund?
- Was the part tested before sale? How?
- Will I receive a receipt?
- Which car was the part taken from and how many kilometres did it have?
If the seller is happy to answer these questions in detail, that is a good sign. If they dodge or give vague answers, think twice.
The warranty is there, you just have to ask for it
A warranty on used car parts is not a luxury, it is a necessity. Especially for more expensive parts, the warranty is your safety net protecting you from financial loss. Buy from registered businesses that offer a written warranty, ask for a receipt, document everything, and do not skimp on professional installation.
On PoDi, when you send a request for a part, you can see which warranties individual suppliers offer and make an informed decision on that basis. You agree the condition and warranty directly with the supplier who sends you the offer.
