Taking the final spot in the UK’s most popular used cars list, with a total of 118,805 sales taking place in 2023 [1], is the Audi A3. This won’t come as a surprise to many, as the Audi A3 is a staple sight on British roads. Depending on which model you get, the Audi A3 combines stylish design, comfort, and advanced technology for a refined driving experience. With efficient engines and safety features, it offers luxury and performance in a compact package. But does that mean it’s reliable? 

What our Reliability Index data says

When scored against our reliability criteria, the Audi A3 came out with a respectable score of 64 out of 100. The index data tells us the most regular Audi A3 repair request area is the cooling system – the system in charge of managing the engine temperature. Signs of a faulty cooling system can include a steaming bonnet, white exhaust smoke, and a rising temperature gauge. Because the cooling system looks after the engine, repairs can be complicated and potentially very costly.

What is the average age of the Audi A3 when faults occur?

According to our data, the average age of an Audi A3 at the time of requested repairs is 7 years.

What is the average mileage of the Audi A3 when faults occur?

The average mileage of an A3 at the time repairs were requested is 71,955 miles. Most vehicles will run efficiently between 50,000 and 80,000 miles [2]. The Audi A3 sits at the top end of this scale, which indicates it could be very reliable. However, all cars will inevitably experience mechanical or electrical problems. It’s safer to be protected by an extended warranty* when that happens, so our friendly warranty experts can help take care of the repairs process for you.

What are the running costs of the Audi A3?

You can buy a second-hand Audi A3 from around £7,000 to £25,000 [3] which is reasonable for a used compact family car. The A3 can fall into insurance groups anywhere between 14 and 46, so estimating insurance cost is difficult – but if you do your homework and have a good driving history, you should be able to find a deal to suit you. On average, Audi A3’s can cover 48-61 miles per gallon, which is certainly not to be sniffed at.

The Audi A3 is proving to be worthy of its position in the UK’s most popular cars list. However, all cars will experience faults in their lifetime. Our data found that the average repair request for an Audi A3 is £1,007, and the highest A3 repair request we’ve received was £10,483! The Audi A3 is a luxury car, so it’s not too surprising to see higher repair costs, but that doesn’t make them any nicer to pay out for. Having an extended warranty* protection plan can make car repairs seem much less daunting – in terms of both stress and cash!

Is the Audi A3 Practical?

If you’re looking for a used car that’s dependable, stylish, and drives well, then the Audi A3 might be for you. The A3 provides a nice amount of interior space throughout the cabin, so passengers should have no complaints about comfort. The A3 is a great option for families, as it offers enough cabin and boot space to accommodate car seats, pushchairs, and luggage of various shapes and sizes.

Warranty FAQ’s.

An extended car warranty from Warrantywise provides protection for your vehicle beyond the manufacturer’s warranty, shielding you from unexpected repair costs that can arise due to mechanical or electrical failures. With additional benefits including recovery, car hire and onward travel, to name but a few, our warranty gives you peace of mind, eliminating the stress and hassle associated with unforeseen repairs and expenses. With access to our network of approved repair centres, you can rely on professional and reliable repairs. By choosing Warrantywise, you can budget more effectively and avoid unexpected costs with cover you can be confident in.

Our retail plans are designed to provide the most comprehensive level of cover available for the age and mileage of your vehicle. We automatically select the most appropriate level of cover for your vehicle, which you can then tailor to meet your specific needs during the online quote process or by speaking with one of our team of warranty experts on 0800 001 4990, who will help you through the process.

At Warrantywise, we aim to make the repair process hassle-free for everyone. When you choose one of our Authorised Repairers, we will handle the settlement of the repair cost directly with them, eliminating the need for you to make any payments. In most cases, you will have nothing to pay at the time of repair. However, if you decide to use an alternative garage or repairer, you may be required to pay the bill in full following an authorised repair. Rest assured, once the repair is verified, we will promptly reimburse you directly for the covered expenses. Our aim is to provide convenience and financial peace of mind throughout the repair journey.

As long as your car has an up to date service history you don’t necessarily need to service the car before we put it on cover. However, if the vehicle doesn’t have evidence that the last service was performed at the correct time, then you will need to arrange to have the car serviced to the manufacturer’s recommendations before your warranty cover is effective. Please refer to Section G – Servicing your vehicle for full details.

No, you don’t have to have a car inspected before it can go on cover.

If that’s the case, please ensure they are VAT registered and follow our provided ‘Repairs Procedure’ outlined in the plan booklet. It’s also crucial to verify that their labor rate aligns with your warranty schedule.
