Faulty car part refund: the 30-day right to reject

You want a faulty car part refund because the mass air flow sensor failed and the returns button on amazon.co.uk has already closed. This is general information about the Consumer Rights Act 2015. It is not legal advice on your order, and it does not say that HouYeen, or any other named seller, will refund you. A qualifying purchase can earn a commission at no extra cost to you. There was no laboratory test.

The clock sits in section 22, at https://www.legislation.gov.uk/ukpga/2015/15/section/22. The explanatory notes, which put the start on the day after delivery, are at https://www.legislation.gov.uk/ukpga/2015/15/section/22/notes . Bromley Council's leaflet on parts a trader fits, including the waiting period, the six-month reverse burden and as described, is at https://www.bromley.gov.uk/leaflet/122488/16/759/d .

In short

The short-term right to reject lasts 30 days, and the explanatory notes start that clock on the day after delivery. Amazon's returns window is the shop's own process. If you agree to a repair or a replacement, section 22 pauses the 30 days for a waiting period. Once that short-term limit has passed, Bromley describes a six-month reverse burden on proof. You deal with the trader who sold the goods.

Satisfactory quality and as described

A part a trader supplies is expected to be of satisfactory quality and to match its description. Satisfactory quality is the standard a reasonable person would regard as satisfactory, taking the description, the price and the other circumstances into account. A sensor that fails in ordinary use soon after it arrives is the sort of problem people raise under that standard.

Whether this one does depends on the facts, including the number on the old part and how the new one was fitted.

Bromley's leaflet treats as described as its own point. A wrong model against the advert is a description problem. The piece in the box can be unbroken and still fail to be the part the listing offered. Keep the order page, because that page is the description you were given. The buying guide is where the original-equipment number is lined up before the next order.

Who sold the goods decides who you claim against. If you bought the sensor and fitted it yourself, the contract for the goods is with the seller of those goods. Fitting it on the drive does not move that contract to a garage you never used.

Bromley's leaflet is about parts supplied in the course of a repair by a trader, including parts that trader fits. A garage that sold the sensor and fitted it during the repair is the setting that leaflet describes.

The 30-day clock

Section 22 is the time limit for the short-term right to reject. The limit is the end of 30 days, and the explanatory notes say the clock starts the day after delivery. If the carrier marked the parcel delivered on 1 October, 2 October is day one and 31 October is day 30. The count does not wait until you fitted the sensor, and it does not wait until a fault code appeared. Take the delivery date from the order.

Within that limit, the short-term right to reject is the Act's early route when goods do not conform. Section 22 times the route. It does not promise that a named seller will pay. You and the trader may agree that rejection stays open later than the 30 days. An agreement that would end the short-term right before the time limit has passed does not bind you.

Amazon's returns window is a shop process. On many orders a button is offered for a set stretch and then closes. A closed button means that shop process has ended. It leaves the statutory clock where the delivery date puts it. The two are easy to mix up, because a shop window is often about 30 days as well. They remain different rules, and the Act is the one in section 22.

A review on the HouYeen 6C11 listing, ASIN B08YNK44VJ, described a failure about a month on, just after the ordinary returns window, and said the seller did not help. Read it as an illustration of that timing problem: the easy window had gone, and the comment records no seller help.

It is not a legal result, and it does not decide a refund on that ASIN or on your order. The same review file includes owners who reported the car running after the swap. The comparison is where that listing sits, with those early failures left in view.

Repair, replacement, and the pause

If you request a repair or a replacement, or you agree to one, section 22 stops the 30-day period for the length of the waiting period. Bromley's leaflet describes that wait for parts supplied in a repair. The waiting period begins on the day you request or agree. It ends on the day you receive the goods the trader supplies in response.

If the goods you receive still do not conform, section 22 sets the short-term limit at whichever ending falls later. One ending is seven days after the day you receive them. The other is your original 30-day period extended by the waiting period. Agreeing to a replacement pauses the clock on those terms. It does not give the trader a shorter limit than the section states.

Keep the conversation on the dates and on whether the goods conform. This page does not give you wording to send, and it does not suggest you threaten the seller. If you are unsure what you agreed, look at the messages you sent and at what came back. The section and the explanatory notes are the texts that define the pause.

After 30 days

When the time limit in section 22 has passed, and the waiting period has not extended it, the short-term right to reject has ended. A fault that appears later can still be raised with the trader who sold the goods. The shop button may already have closed. That records the shop process. The six-month point is a separate rule about proof.

Bromley's leaflet explains a reverse burden for the first six months. If the part does not conform during that period, it is treated as having failed to conform when it was supplied, unless the trader shows otherwise. The presumption allocates proof. It does not mean every failed sensor produces a refund, and it does not record an outcome for any seller on amazon.co.uk. A trader can still show that the fault was not present at supply.

A wrong model stays a description problem. The part can work as a sensor and still be the wrong sensor for the advert. Price and description both sit inside satisfactory quality, so a cheap meter is judged against what a reasonable person would expect of that listing, not against a dealer unit at several times the price. None of that names a refund on a particular order.

If the trader refuses, Citizens Advice is the usual next step in the UK, and people are pointed on from there toward Trading Standards. This page has no Citizens Advice address. Read section 22, the explanatory notes and the Bromley leaflet, then use the dates on your own order. The first person to contact is still the trader who sold the goods.
