According to the data we have, all its engines have the same number of documented faults.

We only count the sourced sheets we have. An engine with fewer is not guaranteed to be more reliable: it may have been studied less or sold in smaller numbers.

Official recalls: ask before you pay

A recall existing does not mean this car is affected or that it is still outstanding: it depends on the chassis number, the market and the production date.

  1. Ask the seller for the chassis number (VIN): it has 17 characters, appears in the car's documents and can usually also be seen at the base of the windscreen.
  2. Ask an official Seat dealer, or the brand's official website if it lets you check by chassis number, whether each recall has been done or is still outstanding for that VIN.
  3. Manufacturer recalls are normally carried out free of charge by the official service network. If one is outstanding, ask for it to be done before you close the sale.

Climate control

  • Look out for: The air does not cool or cools intermittently (for example only at motorway speed), and sometimes the compressor rattles with the A/C on. Codes 01232 (N280 valve), P2612 or 00898.

    Ask them to check: Read the codes and N280 control current with VCDS or ODIS, measure its resistance (about 10 ohms) and check the connector and wiring before replacing parts. If the valve or compressor is replaced, the whole circuit must be flushed.

High-voltage battery

  • Look out for: After several days standing, the high-voltage battery turns out to be flat; rear brakes that stick, rub or have rusty discs.

    Ask them to check: Ask the dealer whether the software is up to date and the battery campaign has been done; check the 12 V battery and ask for the rear brakes to be cleaned at every service. Braking hard now and then helps clean the discs.
