Postal ECU / TCU & garage handover guides
Arrange acceptance, parts, packaging, transit and local refitting as a clear sequence. Useful for owners and garages across the UK.
Plan the enquiry around the actual job.
Posting accepted units can avoid moving the complete vehicle, especially when a local garage has already established the controller job. Confirm which parts and files are needed before removal or dispatch. Mark original and replacement clearly and enclose the agreed reference.
The electronic job, courier transit and vehicle commissioning are separate steps. Give the full return postcode and installer contact. Highlands and island arrangements are checked for the address; a postal enquiry is not acceptance of every controller or a universal turnaround promise.
View the related service and its assessment process, or use the enquiry finder if you are unsure which route fits.
