Hi! I own Estrima Biro. It does not have a diag port in it but it has 2 Sevcon gen4 size2 controllers. One of them gives me 11 LED flashes error, and there's message displayed on dashboard "Cable wiring malfunction". It disappears after ignition key on-off-on. I own ovms3 module. Is there a way to connect it to Sevcon directly, rather than via OBD2?
