We’ve just changed the battery on our 2013 Leon and the tyre pressure warning error has come up. Started the car and whilst idling went into the “Car” menu, “tyre” and then pressed “Calibrate” but it then said “function not currently available” or something like that. Will the system just calibrate itself whilst driving or do we need to press that button whilst on the move to clear the error message? Many thanks!
 
There were lots of warning lights so I did the steering wheel trick and they all went apart from the tyre pressure light. How is a member of the public meant to code a new battery?! Most people don’t have a fancy diagnostic tool. If it’s a like for like battery, is it necessary to code it? This is a 2013 car so not sure it has a fancy battery management system on it. The old battery just died without warning!

If it is an mk3 Leon it should be coded.
If the spec is the same, ok but you should change the serial no. Then the car will "know" it is a new battery. The BMS system uses it when charging.
 
I think you will need to have driven some distance before you can calibrate the tyre pressures. I usually run the calibration when I am on the motorway though others have less success with that. Make sure your tyres are at the correct pressure!
