Audi A4 A5 A6 2.0 2.7 3.0 4.0 TDI CR Tech 2 Diesel Tuning Box Performance Chip.

Bought for my old A4 allroad b8 then swapped for Audi c7 both the 3 litre engine. Was told when I purchased it was interchangeable but never actually got around to fitting to either car. So basically it's brand new just been stored for over a year.
