The picture
Across 1,073 MOT tests, the Leon Se Dynamic Tsi Evo returns 89.6% first-time pass — comfortably ahead of the UK fleet average. The single most-logged Major fail is tyre tread under the limit. A seriously damaged tyre and a tyre with the cords showing round out the top three. Average tested mileage sits at 24,984, which is the lens to read those failure rankings through. If you own one and the next test is close, the ranked list below is a sensible pre-test checklist.

Year-band analysis
First-time MOT pass rate split by registration band. A 2.2-point gap between bands is modest — the year you buy SEAT Leon SE Dynamic Tsi Evo makes a small but real difference to MOT outcomes.
Best band to buy
89.3%
2021+ registration
the 2021-on band climbs to 89.3% — a 2.2-point improvement. Failures here are mostly wear items: has a cut in excess of the…, tread depth below requirements of 1.6mm — the structural issues that drag down older examples don't appear in the top-10 for this band. Post-2020 examples are early in their MOT life and generally show the cleanest records.
Band to be cautious about
87.1%
2018–2020 registration
On the 2018–2020 band, the data shows a 87.1% pass rate against a fleet average of 89.3% on the newer band. The main culprits logged at test: tread depth below requirements of 1.6mm, has a cut in excess of the…, and less than 1.5 mm thick. Average mileage on test for this band is 32,505 miles — high-mileage wear items are a recurring theme.
Best band to buy: 2021+ (89.3% first-time pass). Worst band to avoid: 2018-2020 (87.1% pass). That's a 2.2-point spread across 1,532 older tests and 3,676 newer ones — year of build makes a material difference on this model.

Problem reported with DSG transmission of 2017 SEAT Leon FR purchased in Jerusalem.
Report of 2016 SEAT Leon needing new rear damper because it was "misting" (leaking fluid) at 15,000 miles. FoC under warranty, but dealer recommended replacing the other as well at a cost of £200.
Report of ACC front assist not available warning light on on 2017 SEAT Leon 1.4 EcoTSi 150 DSG Auto Start/Stop FR Technology. (Yellow triangle). Car serviced yesterday and apparently the sensor needs recalibrating at a cost of £400, not covered in the warranty. With this particular sensor off the cruise control does not work either.
Problem reported with DQ200 7-speed dry clutch DSG in 2014 SEAT Leon FR 1.8TSI 180. Error notice on and off: "ERROR: WORKSHOP! ONLY LEAVE VEHICLE IN POSITION P." Owner also notices that sometimes the car automatically switches to the Sports Mode gears while driving, or, more rarely, starts with the Sports Mode directly. With a scanner, he picked up error code: 617752- Selector lever Park position Lock switch. He thinks there is a Technical Service Bulletin for the 617752 error (recommendation to replace gear selector/ shifter assembly?). But online forums have different suggestions.
Ongoing issues with the 1.5 TSI engine with no resolution from SEAT. (These were resolved by a Software update from September 2019.)
Report that 2014 SEAT Leon 1.6 TDi 105 Ecomotive needed new turbo and DPF at a cost of £3,820, but garage then discovered that it needed a replacement engine as well. Replacement engine fitted FoC.
Report of SEAT Leon 1.2TSI engine using 1 litre of oil every 1,000 miles.
Report of turbo actuator of 2015 SEAT Leon 1.4TSI 150 FR failing three times in 28,000 miles.
Report of catastrophic oil loss from engine of 2014 SEAT Leon 1.2TSI (VIN: VSSZZZ5FZER096473) in France. A few minutes before the oil loss, owner heard a faint rattling. French SEAT dealer refused to repair it until they had received confirmation from SEAT that SEAT would pay for the repair. Apparently, this has now been given but the garage now claims that it are waiting for the equipment needed to effect the repair. Owner told that defect itself concerns a pulley coming adrift inside the cylinder head. See 17-7-2018. Likely to be why timing belt replacement on EA211s is being scheduled at 4 years old.
Report of failure of DQ200 7-speed dry clutch DSG transmission in 2013 SEAT Leon 1.8TSI at 35k miles. Car serviced annually by a "specialist". Dealer asking almost £5k to replace.
Report of Mechatronics of 2014 SEAT Leon failing (presumed DQ200 7-speed dry clutch DSG). Owner quoted £1,400 to repair.

Use the failure ranking as a pre-test checklist or a haggling lever. Treat the headline pass rate as a fleet-wide trend, not a guarantee on any individual car.
If you own a Leon SE Dynamic Tsi Evo and your last MOT looked nothing like the ranked failures above, that's normal — individual cars vary widely. The ranking shows the patterns testers flag most often across the country.
