We do not have a stand for the car
and all modules must be removed from the car and delivered to our workshop by mail order
TELWIS has been operating in the automotive electronics industry since 2014, providing online service solutions. Initially, we specialized in the production and sale of memory programmers; however, since 2017 we have focused on the professional repair of automotive electronic modules.
Thanks to a solid technical background, many years of programming experience, and a team of qualified specialists, we are able to effectively diagnose and repair electronic modules—particularly those used in French vehicles, as well as in cars of other brands.
Scope of Services
- repair of BCM, BSI, BSM, ECU, UCH, and other control modules,
- memory and electronic module cloning,
automotive electronics fault diagnostics,
fast turnaround time – usually 1–2 business days.
Cooperation Step by Step
The customer contacts us by phone or via the contact form, providing:
- module type (preferably with a photo of the label),
- vehicle make and model,
- engine type,
- description of the fault symptoms,
- diagnostic error codes.
Based on this information, we assess the repair feasibility and provide a preliminary quote.
Once approved, the module is sent to our service center together with a fault description and contact details.
After the repair is completed (1–2 business days), we return the fully functional module via courier or to the designated parcel locker.
Payment can be made by bank transfer, BLIK, or cash on delivery.
