BMW ISN Change For EGS Gearbox Mechatronic Unit
BMW ISN Change for EGS Gearbox Mechatronic Unit
Often when gearboxes fail, customers opt for second hand units due to the expenditure of a genuine replacement.
(If a used gearbox or Mechatronic unit you will require this service).
When a brand new Mechatronic control unit (within the gearbox) is fitted, it is then coded ‘ONCE’ with a ISN (Individual Serial Number). This serial number is not conventionally changeable as it is part of the vehicles security system. The vehicle will start but not engage any gears, with this system in place BMW can almost guarantee you are required to purchase a brand new replacement.
We now support all E-Series, F-Series and most G-Series vehicles.
If you fit a used replacement part you will find the gearbox will not select any gears (this is an additional safety feature).
At Grosvenor we offer a EGS ISN rewriting service (we are one of very few specialists who can provide this service worldwide), allowing the use of second hand parts.
We would require the vehicle for one working day at a cost of £150 + VAT.
(Most F-Series 8-Speed mechatronic units can be virginised without the vehicle being present meaning we can complete this service before you fit the replacement into a vehicle).
