Greetings all together, my gp4 went after 1h AB drive and 30min lunch break no more. I came from VW and had the xenon passenger side changed. Had still 70°C. brake switch went, went forward, everything ran only the starter didn’t turn. With button and key in emergency start, no sound. No relay clack… batteries both new and full overnight. He threw the error “clamp50 to mass sporadic “. Now he just goes back to what totally unsettled me. Today I could reproduce the thing in so far as the automatic start no longer goes. So briefly push through and wait until it runs. I have to hold the button or the key. Despite new fully charged onboard network battery and charger at the starter battery beats one of the battery relays…? Did the relay 433 swap. So no change. So question. Why doesn’t the automatic start go? Gordon
