Graded against its peers

Better than most family hatchbacks, by age and by mileage. Watch suspension and corrosion. A solid used buy, provided its MOT history has no repeating suspension advisories.

Generation

Split by first-registration year. Cars registered in a changeover year can belong to either generation.

What owners report

Reported

Owner folklore from forums and the motoring press, with how well each report stands up. Most of it never shows up in an MOT, which is why this section exists at all.

Cold-start juddering (“kangarooing”)

Confirmed pattern

The 1.5 evo engine can hesitate and hop when pulling away in the first minutes from cold, mostly on manuals. VW Group acknowledged it in January 2019 and issued a software fix in February 2020; stubborn cases also needed the injector adaptations reset.

Water pump and thermostat module

Emerging

A known weak spot on the EA211 petrol engines. The pump and the plastic thermostat housing are one integrated part, and the plastic cracks with heat cycling until coolant seeps out. The first signs are a low coolant warning, the level dropping between services, a sweet smell around the engine bay, or weak cabin heat. Because the two are integrated they get replaced together, which is why the bill is larger than a water pump sounds: reckon on several hundred pounds at an independent and more at a franchise. Audi has covered some out of warranty on goodwill, so it is worth asking.

Cam belt with no change interval

Disputed

Audi UK says the belt is fitted for life (policy since July 2023, previously 5 years). Independent specialists and many owners change it at 8–10 years anyway, around £400–600, because a snapped belt destroys the engine.

Front suspension knocks and creaks

Partly in the MOT data

Long-running owner complaint: creaks from top mounts, drop links and bushes, often around 60–80k. The measured data partly backs it, with a twist: springs and dampers run above the class average, but bush wear itself stays well below it. The creak is real; the part the forums blame may not be.

S tronic (DQ200) mechatronic failure

EmergingAutomatics only

The expensive one on S tronic cars. The DQ200 is the dry clutch seven speed, and two things go wrong with it: the clutch packs wear and start juddering as you pull away, and the mechatronic unit develops micro cracks around the pressure accumulator, bringing on jerky shifts, an EPC light, or a refusal to select a gear at all. Owners warn that replacing the clutch pack without the mechatronic unit that killed it just buys you the same fault again. Reckon on four figures either way, and check the gearbox oil has been changed on schedule rather than treated as a lifetime fill.

What to check on this car

Ranked from this model’s own MOT record, then from what owners report.

Saveable checklist

From this model’s MOT record

The physical checks its own defect data says are worth your time, most telling first.

DampersRuns high on this model Look for oil misting on the damper body behind each wheel, then push down hard on each corner of the car. It should settle in one bounce. A floaty or crashy ride on the test drive is the same fault felt from the driver's seat.Recorded on 5.5% of tests at age 6-9 · class average 2.3%
Underneath, with a torchRuns high on this model Get down and look at the sills, the subframes and the rear suspension mounting points. Flaking scale and bubbling matter; light surface rust does not. On older cars this is the one check that finds the fault that scraps them.Recorded on 2.3% of tests at age 6-9 · class average 0.7%
Bushes and ball joints Drive slowly over broken tarmac with the windows down and listen for clonks from either end. Back at the car, have someone rock the steering wheel while you rest a hand on each front wheel; play you can feel through the tyre is a worn joint.Recorded on 2.0% of tests at age 6-9 · class average 5.9%
Leaks Look at the ground where the car usually stands, then glance under the engine after your test drive. Fresh drips of oil or coolant are the cheapest warning you will ever get about a car.Recorded on 1.6% of tests at age 6-9 · class average 2.0%
Coil springs Look through the wheel spokes at the bottom coil of each spring; when springs snap it is usually there, and the break is visible. Step back and check the car sits level too. A dropped corner is often a broken spring.Recorded on 1.2% of tests at age 6-9 · class average 1.4%

Worth doing on any used car

These judge the seller’s upkeep rather than the model, and they are where the haggling money is.

Tyres, all four Check the tread across the full width of each tyre, inner edge included, and look for cracking and mismatched brands. A set of decent tyres is £500 or more on most cars, which makes this the easiest money to take off a price. If the pressure warning light is on, budget for sensors too.Recorded on 23.2% of tests at age 6-9 · class average 20.1%
Pads and discs Look through the wheel spokes at the brake disc. A pronounced lip on its outer edge, or a rusty and scored face, means discs and pads are due all round, a few hundred pounds on most cars. A haggling point rather than a reason to walk away.Recorded on 12.1% of tests at age 6-9 · class average 10.1%
Windscreen and wipers Scan the glass in daylight for chips, especially in the driver's line of sight where even a small one can fail the MOT. Run the washers and check the wipers clear without smearing.Recorded on 2.4% of tests at age 6-9 · class average 2.0%

Because of what owners report

Drawn from the reports above rather than the MOT data. These are the model-specific ones.

Start it stone cold and pull away gently. Any hopping or hesitation in the first minute is the kangarooing fault.
Ask whether the February 2020 engine software update was applied. A dealer can confirm it against the VIN in minutes.
Check the coolant level and ask about top-ups. A dropping level points at the water pump module.
Ask for cam belt receipts on cars 8 years or older. None? Price a £400–600 change into your offer.
Drive slowly on full lock and listen to the front end. Creaks mean bushes or top mounts.
Look for damper misting and ask if springs were ever replaced. Shocks and springs are the only MOT items where this model runs worse than its class.
Read the MOT history, not just the pass. The same advisory three years running means nobody is fixing anything.
