Hi all, I'm new to the group and to the Opel brand. We have bought a 2017 Zafira tourer c 1.4t and ran into a problem today. The car seems to suffer a misfire under load and thrown an engine warning light which then clears (over and over). I have tried a generic code reader, but the car seems to clear the codes before I get a chance. My question is whether anyone has a link to download a Virtual Machine image with the GM diagnostic software installed ??
