Elprosys Sp. z o.o., Tarnogórska 140, 44-102 Gliwice, was established in 2000. The company describes DiagProg as its flagship diagnostic tester for repair and programming of modules such as airbag sensors, engine controllers, odometers and ABS pumps. The company site says that line has been developed for over 15 years. The DiagProg shop's about page still describes a fourth generation and uses the figure "over 10 years", so the two Elprosys pages do not agree. Use the current shop listing rather than either sentence as a model history.
Retailers sell packages named DiagProg 4 and DiagProg 5 for odometer work. Those trade names come from seller pages, not from a model-by-model specification on the Elprosys homepage. Confirm the generation, the vehicle authorisation and the lead set with Elprosys.
