M3.8.5 ECU Files for Seat & VW

M3.8.5 is an electronic control unit. We currently have 2 M3.8.5 files in stock and 2 hardware numbers. Each one is an original read from a working unit. Vehicles that use this unit here include VW and SEAT. Frequent models: GOLF and TOLEDO. Available as Immo Off and Original File files. 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.
