Are Audi cars reliable?
Audi vs other premium brands
Audi vehicles pass their MOT at 78.4%, six points above the national average of 72.4%. Among premium brands, Audi sits in the middle of the pack, behind Porsche (87.5%), Jaguar and BMW (both 79.3%), and just ahead of Land Rover and Mercedes.
The Audi range is dominated by the A3, A4, and A1, which together account for roughly half of all UK Audi MOT tests. Larger and newer models like the Q5 and Q3 pass at higher rates than the smaller cars.
Reliability data shows part of the picture. A vehicle history check reveals the rest, including outstanding finance, stolen markers, write-offs, and mileage discrepancies.
What is the Audi MOT pass rate by age?
Pass rate at each vehicle age, from 3 to 20 years old. National average shown for comparison.
Newer Audis (3 to 5 years old) pass at 89 to 91%, above the national average for the same age range. The gap widens through the middle years: at age 12, Audis pass at 73% while the national average is 66%.
Audi pass rates stay above the national average at every age from 3 through to 20 years old. By 20 years, the gap narrows to around 3 points, but Audis still outperform the average car of the same age.

Top 5 specific Audi failure reasons
These are the specific MOT examiner findings most frequently recorded on Audi vehicles, along with what they mean.
- Tread depth below requirements of 1.6mm (6.03% of Audi failures)
One or more tyres worn below the legal minimum tread depth. The legal limit is 1.6mm across the central three-quarters of the tyre.
- Fractured or broken (5.91% of Audi failures)
A suspension arm, spring, or bracket has snapped or cracked. The affected part must be replaced before the vehicle is roadworthy.
- Damaged but not adversely affecting driver's view (5.81% of Audi failures)
Windscreen damage such as a chip or crack that has not yet spread into the driver's line of sight. Commonly caused by road debris.
- Pin or bush excessively worn (4.74% of Audi failures)
The metal pins or rubber bushes that connect suspension components have worn past their safe tolerance, creating play in the joint.
- Constant velocity boot severely deteriorated (4.22% of Audi failures)
The rubber cover protecting a CV joint on the driveshaft has split or torn. Left unfixed, dirt enters the joint and it fails.
Audi's failure profile has a distinctive tilt. Suspension issues account for 22.7% of failures compared with 20.7% nationally, and tyre failures are notably higher at 17.1% vs 10.6% nationally - likely reflecting the firm suspension setup and larger wheels fitted across the range. Lamps and electrical failures are lower than average, which fits the newer average age of Audi cars on the road.
Which Audi models are most reliable?
Top 15 Audi models ranked by MOT test volume. Pass rate shown for each. Green bars beat the national average of 72.4%. Red bars sit below it.
| Model | Tests | Pass rate | Most common failure |
|---|---|---|---|
| Audi A3 | 331,156 | 74.1% | Suspension |
| Audi A4 | 203,149 | 71.8% | Suspension |
| Audi A1 | 194,368 | 75.2% | Suspension |
| Audi A5 | 101,864 | 76.3% | Suspension |
| Audi A6 | 100,235 | 78.5% | Lamps, reflectors and electrical equipment |
| Audi Tt | 99,032 | 76.6% | Lamps, reflectors and electrical equipment |
| Audi Q3 | 93,586 | 79.2% | Suspension |
| Audi Q5 | 84,647 | 81.8% | Suspension |
| Audi Q2 | 70,939 | 90.2% | Tyres |
| Audi Q7 | 35,933 | 81.0% | Lamps, reflectors and electrical equipment |
| Audi A7 | 14,176 | 84.2% | Tyres |
| Audi A8 | 9,209 | 86.5% | Lamps, reflectors and electrical equipment |
| Audi A3 S LINE 35 TFSI MHEV S-A | 7,435 | 90.3% | Tyres |
| Audi Q3 S LINE 35 TFSI MHEV S-A | 6,539 | 93.0% | Tyres |
| Audi A2 | 5,185 | 56.3% | Lamps, reflectors and electrical equipment |
The Q5 and Q3 are Audi's top performers among the higher-volume models, both passing above the Audi average. The A4 sits lowest of the popular models at 71.8%, below the national average, while the A3 (Audi's highest-volume model) passes at 74.1%. Tyre and suspension failures are the most common categories on Audi vehicles. This is consistent with the heavier weight and lower-profile tyres fitted across much of the range.
How many miles do Audi vehicles typically cover?
Average recorded mileage at each MOT test, by vehicle age. National average shown for comparison.
Audi mileage tracks close to the national average for the first three years, then pulls above it from age 6 onward. By age 10, Audis average about 85,000 miles vs the national 80,000. By age 20 the gap widens further, with Audis averaging around 133,000 miles vs the national 111,000 - consistent with the executive-car and company-fleet profile of the brand.
Our Premium Vehicle Reports compare the recorded mileage at every MOT test to flag discrepancies. A drop in recorded mileage between two tests is a strong signal that the odometer may have been tampered with.
Are there any Audi safety recalls?
Safety recalls are issued by Audi when a manufacturing defect could affect the safety of the vehicle. The DVSA records every UK recall and links it to affected vehicle identification numbers (VINs). Recalls are free for the owner to have fixed at a franchised dealer.
Recall lists change over time as new issues are identified and old ones are resolved. For that reason we do not maintain a static list here. When you check a Audi via Brumble, the report shows any outstanding manufacturer safety recalls that still need action on that specific vehicle.
How do you check a Audi's full history?
Before you buy any used Audi, a full history check protects you from problems that a physical inspection would miss. Here is what a Premium Vehicle Report from Brumble covers.
Has this Audi been written off?
An insurance write-off means the car has been declared uneconomical to repair after an accident, fire, or flood. The report shows the category (Cat A, B, N, or S), the date, and the cause. Cat A and B are permanently unroadworthy. Cat N and S can legally return to the road but often carry hidden damage and are worth significantly less.
Is there outstanding finance on this Audi?
If the previous owner has an active HP, PCP, or loan agreement secured against the car, the finance company legally owns it until the balance is paid off. Buying a car with outstanding finance means the finance company can repossess it, even after you have paid the seller in full. The report checks with Experian for any active finance agreements.
Has this Audi been reported stolen?
The Police National Computer records stolen vehicles. The report checks the PNC for any active stolen marker. Buying a stolen vehicle means the police can seize it and return it to the rightful owner, with no compensation.
Has the mileage been tampered with?
Every MOT test records the current mileage. The report shows the full mileage history from every recorded test and flags any drops or unusually flat periods. A drop between tests is a strong signal the odometer has been clocked. A car worth £15,000 with 60,000 miles on the clock might be worth £10,000 if the true mileage is 120,000.
Has this Audi been used as a taxi or private hire vehicle?
Ex-taxis and private hire vehicles have typically covered high mileage under harder use than a private car of the same age. Insurers may view them as higher risk, and resale value is significantly lower. The report checks whether the vehicle has ever been registered as a taxi or private hire vehicle.
What is this Audi worth?
The report includes current trade, retail, and private-sale valuations based on the vehicle's make, model, trim, mileage, and condition. Use it to check whether the asking price is fair before you negotiate.
