My wife has the same car wayne and i initially wanted this for her car but it will only fit on electronic injectors and not the pd injectors. Thats why i put it on my 2010 a6 but that was on lease and has gone back thats why the unit is now for sale. its a great bit of kit but i knew it would never sell to retail as it was going to be £450+vat and upwards. the map unit was £350+vat and the programming handset was £350+vat. so it wont do your leon. i have remapped my wifes just with a standard obd re-map. eats tyres now though
