Split by first-registration year. Cars registered in a changeover year can belong to either generation.
Computed from DVSA MOT results, all of Great Britain, 2025. Nothing here is opinion.
Share of tests where each item was recorded. The dark tick is the class average across all tracked models; bars are scaled within each group.
The rows that judge the model rather than its keeper. 89,181 tests in this band.
Tyres, pads and stone chips say more about how the car was driven and maintained than about how it was built.
Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.
A rattly, metallic noise on cold start that owners often mistake for a tappet tick is usually the timing chain and tensioner stretching. Left alone it can jump time and bend valves, and one Honest John reader's 1.2 TFSI needed a £7,500 engine after exactly this at 65,000 miles. It's a widely known VAG-group weak point on this generation of small turbo petrols, not unique to Audi, and mostly shows on higher-mileage cars that have missed oil changes.
The 7-speed S tronic auto, badged DQ200 on most A1s, is known for mechatronic unit failures and jerky, hesitant or clunky low-speed shifts as the dry clutch packs wear. Honest John owner reports include failures at 27,500 and 37,500 miles, and a software update that only fixed things temporarily. Repairs run from a few hundred pounds for a clutch pack to well over £1,500 for a new mechatronic unit. Only relevant if you're looking at an automatic; manual A1s don't have this gearbox.
Front windows sticking half-open or refusing to drop when the door opens is a very commonly reported fault, traced to a weak regulator mechanism shared with the Polo and a protective coating on the door seals that turns gummy over time. It's a nuisance rather than a safety issue and a cheap regulator or seal clean-up usually sorts it, but it comes up on cars of all ages and mileages.
Owners regularly report weeping or leaking rear dampers turning up at the first MOT around 20-25k miles, plus a handful of snapped coil springs, sometimes twice on the same car. This lines up with the measured MOT data for this class, where suspension is the standout fault category for superminis generally; the A1 owner reports specifically call out rear dampers and springs rather than bushes or links, so if you hear a knock, look there first.
Diesel A1s with the 1.6 TDI show the usual small-diesel problem: short urban journeys don't get the DPF hot enough to regenerate, leading to warning lights, sluggish performance and, in a couple of reported cases, diesel over-fuelling into the sump during a failed regeneration that overfilled the oil level. That's a genuinely damaging fault if it happens, not just an annoyance, and it points more at driving pattern than a single bad part. No manufacturer campaign found, so treat it as owner-reported rather than acknowledged.
A scatter of owners report MMI screens failing outright (one quote for over £3,500 to replace) and separate reports of water getting into the tailgate or cabin, sometimes on nearly new cars, causing condensation or misted windows. These come up often enough to note but aren't consistent enough to call a pattern; some may be one-off build issues rather than a shared design fault, so owners disagree on how common it really is.
