The most common problems on the Seat Leon Sport TDI are tyre has ply or cords exposed (3 recorded failures), constant velocity joint gaiter split (2), and tyre tread depth below requirements of 1.6mm (2). These are the faults most likely to cause an MOT failure on this model, so check for them carefully on any test drive or pre-purchase inspection.

Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
