About DCM3.7 files

DCM3.7 is a Delphi common-rail diesel engine control unit. We currently have 8 DCM3.7 files in stock, covering 8 different software numbers and 7 hardware numbers. Each one is an original read from a working unit. Vehicles that use this unit here include Volkswagen, SEAT and KIA. Frequent models: POLO, IBIZA and RIO. Available as Original File dumps. These dumps were read with NEW TRASDATA and KTAG, 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.
