Audi Reliability: A Breakdown By Model
OK. Let’s get one thing straight before we begin…
Audi makes premium vehicles loaded with high-tech gadgetry. This technology ensures an absolutely fantastic driving experience. But it also creates more complex systems that can develop faults as they age.
Indeed, RepairPal data suggests that the average Audi costs approximately £780 per year in repairs. That’s higher than mainstream brands but comparable to other premium German marques.
However…
The key insight is that reliability varies massively between different Audi models and year ranges.
Some are true to their German engineering pedigree and are like rental cars that just keep going. Others are infamous for particular issues that any savvy used buyer would steer clear of entirely.
On a positive note, modern Audis are leagues better than models from a decade or two ago. In fact, a well-maintained example can cruise past the 150,000 – 200,000-mile mark without any major faults or breakdowns.
The Most Reliable Used Audi Models To Buy
Not all Audi models are created equal when it comes to reliability. In fact, certain models are far more dependable than others.
So which used Audis should be at the top of your list?
Audi A4
A4 is the workhorse of the Audi lineup and a solid reliable choice for most people. They are very usable day-to-day family cars and great as executive transport. Earlier cars suffered from oil consumption issues and some electrical gremlins. But more recent model years from 2018 onwards have had updated infotainment systems with fewer bugs. These models score highest in owner satisfaction surveys.
Audi Q5
The Q5 SUV is practical, but with a premium feel that sets it apart from the cheaper rivals. The 2017 model year onwards saw a notable jump in interior quality and reliability rating.
These are one of the more reliable Audi SUVs you can find on the used market. They do have slightly higher maintenance costs than the average car though due to the AWD system.
Audi A3
The A3 is a great entry point into Audi ownership. They are compact enough that there are less things that can go wrong compared to bigger models.
Look at A3s from 2016 and above for particularly good reliability scores.
Red Flags To Look Out For
Look out for these telltale signs when perusing used Audi listings.
Electrical Gremlins
Audi vehicles are fitted with cutting-edge electronics that go beyond most other makes. This is a blessing and a curse. The moment you switch the car on make sure that all screens function, the infotainment system is responsive and no warning lights are flashing intermittently.
The infotainment screen sometimes has problems connecting to your phone via Bluetooth or slows down over time. These may indicate a software or hardware issue.
Oil Consumption
Earlier 2.0T engines from certain model years were also known for burning oil. Check with the seller about their oil consumption between services.
If they have to top up frequently between oil changes then it’s an indicator of worn piston rings or valve seals. Replacements are expensive.
Suspension Noise
Pay attention when driving the car over bumps. There shouldn’t be any clunking or knocking sounds from the suspension. Audi uses premium suspension parts but they do wear out. Control arm bushes and shock absorber forks are common areas of failure.
Suspension repairs are costly on premium cars.
Essential Pre-Purchase Checks
Make sure to do these checks before buying any used Audi.
Electrical Tests
Spend at least 15 minutes testing every button, feature and screen. This includes climate controls, heated seats, parking sensors, reversing camera etc. It all needs to work correctly. Electrical repairs on modern Audis usually require the dealer’s diagnostic kit.
Check Under The Car
Look underneath the car for evidence of oil leaks or damp patches. Small dribbles around gaskets are common on older cars. Actively dripping is a whole different matter. Check the condition of the brake discs and pads too while you’re down there.
Interior Wear
It’s amazing how long Audi interiors can hide high mileage thanks to their premium materials. Look at the condition of the pedals, steering wheel and seat bolsters and compare them to the stated mileage.
Excessive wear on a low-mileage car could indicate mileage tampering.
Inspect The Alloy Wheels
Lots of Audis come with large alloy wheels that cost a small fortune to repair or replace. Kerb damage is common on all cars and expensive to fix properly.
Bear this in mind when it comes to price negotiations.
Verifying The Service History
The service history is absolutely crucial when it comes to used Audi cars. No exceptions.
Why History Matters
Regular servicing is key to keeping Audi engines ticking over. A skipped oil change and you have sludge. Forget a timing belt replacement and you’ve got engine failure.
A stamped-up service book from a main dealer is gold standard. Although stamps from an independent specialist are good enough.
What To Look For
Every service should be recorded along with mileage and date. Check that the intervals are consistent and haven’t been stretched.
Major services on Audis include timing belt replacement, gearbox oil change and brake fluid renewal. Look out for these and make sure they were done on time.
HPI And Background Checks
Do an HPI check before you part with a penny. You need to know it’s not stolen, written off or still under finance.
Also confirm the mileage history through the MOT records available free online.
Wrapping Up
Finding a reliable used Audi doesn’t have to be difficult if you know what you’re doing. Audi’s build quality and driving experience is up there with the best of them so the premium pricing is justified.
Prioritize these essentials:
- Pick a model and year that have great reliability ratings
- Ensure it has a full service history
- Test every electrical feature to check for faults
- Inspect the car for model-specific problems
- Get a pre-purchase inspection from a professional
Enjoy the fruits of your patience. You’ll be rewarded with years of premium motoring pleasure in a well-chosen used Audi. A poorly researched purchase however, becomes an expensive headache you didn’t need.
Do your research and use the tips above and you can be sure to find a used Audi that serves you brilliantly for years to come.
