About SIMOS7.1 files

SIMOS7.1 is a Continental/Siemens petrol engine control unit used by the VAG group. We currently have 10 SIMOS7.1 files in stock, covering 4 different software numbers and 5 hardware numbers. Each one is an original read from a working unit.Vehicles that use this unit here include VW, Audi, SEAT and Volkswagen. Frequent models: GOLF, A3, PASSAT and LEON. Available as Immo Off and Original File files.These dumps were read with FLEX, so they load straight into the same tool. Always compare the software number on your label with the number in the file title: two units with the same ECU type can still need different software. Missing your version? Request the file with the label numbers and we will source it.
