I would take it to a specialist, to diagnose/clone/repair/replace.

Thank you very much!Hell Razor5543 wrote: 14 Aug 2026, 14:54 The thing to understand is that parts may be used across various vehicles. That BSI model could (for example) be used in the diesel C3 range, the C4 range and the C5 range. Once it has be configured with all of the settings for YOUR vehicle it should (barring any other issues) work properly.
