Just over a year old. (See receipt picture) Bought for my 68 plate 520d and on the car for a year. It has a 1 off free reprogram if the car gets changed with the manufacturer. Included is the original invoice so you can see all is correct. This is the upgraded Bluetooth version of their tuning box which allows you to control it via their app while on the move.

It does make a massive difference to power and untraceable if in warranty.
