Well this is not the first time, but I just thought I fixed the issue before so ignored it.
Sometimes after turning the engine off and then a few minutes later back on the car tends to struggle to stay on but does not turn off (RPM drop really low then back to normal (700rpm -warm)). In addition the car begins to smoke a little somewhere around the turbo. All in all I would like to know what exactly is this and how to fix it. I've tried researching this but had no luck finding anything.
