was having a few problems with the gauges on a new 420R firstly rev counter, going off dial and now speedo flicking. I guess as VDO gauges they are all stepper motor. Unfortunately I could not replicated fault at dealer. They also said they could not do a diagnostic, which I found as odd. while speaking to a fellow owner at Brands last week, they said there is a plug loosely strapped to the steering column which I found. I decided to do some more research and found this. OBD It looks like access is blocked. Any idea of path forward ? I understand that Luke Stevens can access maps for his rolling road work and he is local to me.
