Audi RS6 — MOT statistics 2024

The Audi RS6 failed 17.37% of 639 first MOT attempts in 2024 ("first-time", excluding retests). Adjusted for the age of the fleet, its initial-failure ratio is 45.9 (100 = expected for its age profile). This car fails its MOT about 54% less often than expected for its age. Small sample — treat with care.

Age-adjusted peer: Audi A8 (index 45.5) — the two published results are 0.4 index points apart.

Audi RS6 common problems: what actually fails the MOT

Suspension is well below the reference at 5.9 per 100 tests, against 23.1 per 100 tests across UK vehicles of the same ages.

higher bar = fails more oftenrate per 100 tests

family vs national — matched to UK vehicles of the same ages — top component groups, per 100 tests. Legend: This family · National avg. Combined labels: family / national average. A gap here reflects how these vehicles are driven, used and maintained as well as how they were built — an MOT defect is a test outcome, not a breakdown.

Named defects ranked by how much more often they appear than the national average — not by raw rate.

Audi RS6 MOT advisories: what gets flagged

Brakes are highest at 29.5 per 100 tests; Body & structure are lowest at 3.3 per 100 tests — the gap is 26.2 per 100 tests.

Advisories are wear the tester noted but didn't fail — what will need money soon.

If a car like this fails, does it fail again?

A failure rate does not say whether a failure is a one-off or the start of something. This follows the same vehicles into their next ordinary MOT a year later — retests after a repair are excluded, because they follow a failure by definition. 2019-2024.

A failed test does not clearly change next year's odds here (12.2% against 14.6%): the difference is within the margin of error. The failure most likely to come back is lamps, reflectors and electrical equipment — 17.3% of those vehicles fail again next year. Some of this is the vehicle and some is the owner: a car that was let go once tends to be let go again. One caveat: a car that fails may be sold or scrapped rather than tested again, so these figures describe the vehicles that came back.

Adjusted for how much these are actually driven

The headline index adjusts for the fleet's age. Wear, though, follows mileage: a three-year-old taxi and a three-year-old garage queen sit in the same age band. These two rows compare every car with vehicles of the same age, and then with vehicles of the same age and the same annual mileage, 2019-2024, on 4,201 tests. Both stand on the six-year corpus so they are measured on identical data — compare them with each other, not with the headline index above, which is measured on 2024 alone.

Mileage changes little here (-0.4 points): this fleet is driven about as much as the vehicles it is compared with. One limit to keep in mind: mileage is partly a result of how often a car breaks down — one that spends weeks in the workshop covers fewer miles — so the mileage-matched figure can understate a real weakness. Tests with no usable odometer reading are left out of it.

How the Audi RS6 compares with cars of its own age and size

Not against the whole fleet — against cars of the same size class tested at the same age, 2019-2024.

Raw first-time failure rates within each age, so fleet age cannot flatter either side. A positive difference means this model fails more often than its own class at that age.

How does the Audi RS6 perform as it gets older?

The RS6 at age 16 is well below the reference at 16.8%, against 43.1% for all vehicles of the same age.

How dangerous are Audi RS6 MOT failures?

Major defects are well below the reference at 28.7 per 100 tests, against 52.8 per 100 tests nationally.

Does the month of an Audi RS6 MOT matter?

Feb is highest at 21.2%; Apr is lowest at 11.9% — the gap is 9.3 percentage points.

higher = larger sharecompare shares in percentage points

Chart scale: 10%–33%.

bars: Audi RS6 · dashed: all class-4 cars

Takeaway: the spread between best and worst month is 9.3 percentage points — noticeable seasonality. Seasonality partly reflects registration-date clustering, not weather.

Before reading the shape: most of it is not about cars. Britain changes its registration plates twice a year, and 18.9% of these cars were first registered in March with another17.1% in September — 36% in two months against the 17% an even spread would give. An MOT falls due three years after first registration, so the buying calendar becomes the testing calendar. That shapes how many cars are tested each month — not how often they fail: the busiest months here are not the worst ones, so read the failure line on its own and the volume behind it separately.

Audi RS6 average mileage by age

At age 16, the middle half of RS6s runs from 76,048 miles to 117,942 miles, against 96,836 miles as the median.

Does high mileage mean more Audi RS6 MOT failures at the same age?

Within the same age group, split by odometer (2024 MOTs), so this separates wear from age: at ages 15+, 19.5% of those with 70,000–100,000 miles failed first time versus 23.3% of those with 100,000–140,000 miles.No clear mileage gap inside this age group, among cars still being tested.

line: median · band: middle half of the fleet (p25–p75)

A typical 16-year-old RS6 has ~96,836 miles on the clock. Much more — ask why; much less — check for gaps in the MOT history.

Where in Britain the Audi RS6 fails its MOT most

Too few tests in any single postcode area to name one, so this is the wider picture across 4,212 tests, 2019-2024.

Raw pass/fail rates, not age-adjusted: fleets differ by region. England is split north of Sheffield, between Sheffield and Oxford, and south of it.

Audi RS6 survival: which cars are still on the road

By age 19 is close to the reference at 100.0%, against 100.0% at the ages 4–6 reference level.

higher = larger sharecompare shares in percentage points

Chart axes: car age, years · survival vs ages 4–6 · scale 0–105%.

By age 19, at least as many cars of this family present for MOT as at ages 4–6 (reference n≈170): the older fleet has not thinned out here, so there is no survivor selection to allow for.

How many miles does an Audi RS6 last?

100,000+ miles stands out at 32.8%.

higher = larger sharecompare shares in percentage points

Of 4,210 tests of this family with a usable odometer in 2024, 32.8% had reached 100k miles. This is a cross-section of cars still presenting for MOT, not a full birth cohort.

How many years is an Audi RS6 likely to last?

Bought at age 5 is highest at 16.6 years; Bought at age 15 is lowest at 4.5 years — the gap is 12.1 years.

bigger number = longer remaining lifeyears on the observed survival curve

estimateEstimate only — not a warranty: a typical 10-year-old example of this family has at least 9.5 expected years of further MOT-present life. The curve is observed only until age 19, so the true figure is likely higher.

Audi RS6 faults that come together

Body & structure + Emissions & leaks stand out at 7.40×, against 1.00× if the faults were independent.

above 1.0× = more than expectedbelow 1.0× = less

Defects in «Body, chassis, structure» and «Noise, emissions and leaks» appear together 7.40× more often than chance (27 co-occurrences in the same test; 66 pairs compared).

Lift = how many times more often both groups appear on the same test than if independent. A pair is listed from 5 tests with both faults; the lift is shown from 20, and called above chance only when its 95% interval excludes 1 (see rough estimates).

Is low mileage better for an Audi RS6?

Cars driven under 5,000 miles a year is well below the reference at 10.7%, against 14.6% for cars driven 8,000–12,000 miles a year.

higher = larger sharecompare shares in percentage points

At matched ages 5–14, cars averaging under 5k miles/year fail at 10.7% vs 14.6% for 8–12k miles/year — 4.0 pp, interval includes no difference (n_low=309, n_normal=541). The gap interval includes no difference, so no higher/lower claim is made.

Audi RS6 MOT repair costs

The MOT-failure repair budget per test runs from £48.33 to £91.83, against £54.85 for the test itself.

bigger number = costs morepounds per test, MOT-failing faults only

Multiply how often each component fails on this model by what that repair usually costs, and you get the amount an owner should expect to budget per test for MOT-failing faults only — roughly £48 to £92, on top of the test fee itself. It is a budgeting figure, not a quote: the spread between a set of pads and a set of discs is most of the range.

Prices are modal quotes from a hand-kept catalogue of published UK garage guides — we do not scrape the booking sites, their terms forbid it, so this list is short and updated by hand with a source and date against each line. Each line prices one typical repair in that group, not a full remedy, and only groups our catalogue actually covers are counted. The contrast worth noticing is the second card: the legal maximum for the test has been £54.85 since 2010, while the repairs it uncovers have followed inflation the whole time.

For scale from a different direction: Warrantywise, which sees used-car warranty claims rather than test failures, puts the average claim at £2,052 across the ten highest-claim models it ranks and £539 for Honda, the lowest-claim make in its index (Warrantywise index 2026, 1.6 million claims, cars aged 3–15). Those sit an order of magnitude above the figures in this table, and the gap is the point: a warranty claim is a gearbox or an engine, which almost never fails an MOT, while the faults that do fail one are corrosion, lamps and tyres, which no warranty pays for. The two numbers answer different questions and neither replaces the other.

Audi RS6 running costs for a fleet

No single year stands out as the point where this model starts costing more: the year-to-year steps in its failure rate are too small or rest on too few tests to name one (D1 rule: a step is named only with at least 2,000 tests on both sides and a jump above 3 percentage points).

Repair spend uses the same modal prices as the section above, so it inherits the same limits: one typical repair per component group, not a full remedy. Downtime is the gap between the failed test and the passed re-test, which is the window a vehicle is legally off the road.

Audi RS6 rust problems: where they corrode

Age-standardised corrosion susceptibility is well below the reference at 0.23×, against 1.00× for the national age-standardised rate.

above 1.0× = rusts more than averagebelow 1.0× = rusts less

This Audi RS6 fails on corrosion much less often than average once age is held constant, and its owners live in areas that are about typical for the models we publish. Both point the same way and reinforce each other: it resists corrosion even though its owners live in saltier areas than most.

Corrosion is the one failure mode that is as much about geography as about the car. We keep the two apart on purpose: a model can look rusty simply because it is popular in Scotland, and a model can look clean simply because it is bought in Surrey. Blending them into a single score would hide which of the two is doing the work.

Exposure is this model's tests weighted by an area corrosion index built from frost days, salt load and distance to the coast — the composite validated at r = 0.42 against corrosion defects we actually record. It is published as a rank, not a raw score, because every mainstream model skews towards low-corrosion areas for the simple reason that most of Britain's cars are in the south. Susceptibility is standardised to the national age profile, so an old fleet does not get labelled a rusty model.

What will fail next on an Audi RS6?

Lamps, reflectors and electrical equipment after a advisory at age 15-19 are highest at 14.0%; Lamps, reflectors and electrical equipment after a passed at age 6-8 are lowest at 2.3% — the gap is 11.7 percentage points.

higher = more likelypercentage is the observed transition probability

The same chains, cut differently: given a car's age and how its last test went, which component most often causes trouble at the following one.

The pattern that repeats across every family: a failure at one test roughly doubles the chance of a failure on the same component at the next one, and an advisory sits about half-way between a clean pass and a failure. Age bands in years; probabilities are per car, not per defect item.

Audi RS6 ownership: what six years of MOTs show

Clean three-test streak is highest at 52.5%; Repeated the same advisory is lowest at 18.0% — the gap is 34.5 percentage points.

higher = larger sharecompare shares in percentage points

Per mile driven, not per year. Dividing failures by the miles that actually went onto the odometers between consecutive tests gives 0.397 failures per 10,000 miles, on a median of 2,863 miles a year across 836 chains. This is the number to compare between models — an annual rate quietly rewards cars that barely leave the drive.

Two populations hide inside one model. 52.53% of these cars strung together three or more tests with nothing recorded at all, while 18.03% carried the same advisory three times or more — the same fault, noted, ignored, noted again. When you buy used you are buying one of those two histories, and the MOT record shows which.

Odometer anomalies: 1.673% of 837 chains show a reading lower than the previous test, with a median drop of 27,004 miles. We call this an anomaly and not fraud on purpose — instrument swaps, imports, unit mix-ups and keying errors all land in the same bucket. Obvious typos (drops under 100 miles or over 90% of the reading) are already excluded.

Audi RS6 safety recalls and how to check yours

DVSA recall campaigns stand out at 4.

bigger number = more recorded casescompare like-for-like scope, not sample size alone

recall campaigns launched per year

DVSA lists 4 safety recall campaigns for the Audi RS6, covering roughly 504 vehicles in total. A recall is the manufacturer fixing a fault for free, so an open recall on your car costs nothing to clear.

Counter-intuitive, and measured on our own data: across the 25 families published here, more recalls go with a lower MOT Risk Index (r = −0.52). Heavily recalled models are not worse cars in the test bay — an active manufacturer removes the fault before it becomes an MOT failure.

Audi RS6 MOT: quick answers

Audi RS6 MOT Risk Index is well below the reference at 45.9, against 100 for a car with the same age profile.

below 100 is betterabove 100 is worse100 = normal for this model at that age

What is the Audi RS6 first-time MOT pass rate?

82.63% of first attempts passed in 2024 (639 tests). This is the first-time figure: retests after repair are excluded. Basis: first-time, excluding retests.

Why does this number differ from other sites?

Other sites often report a pass rate that includes retests or counts all attempts. Our 17.37% figure is the first-time initial failure rate, using 639 primary tests as the denominator (first-time, excluding retests). The age-adjusted MOT initial-failure ratio 45.9 is shown separately because raw rates compare fleet age as well as cars.
