I could really do with some help b 4 I take it bk to the garage next week, my car is my pride. & joy !!! Oh somebody said it cud be the battery as it mainly does it when I start it to go to work in the morning then when I leave work, switch engine on & off & sometimes it goes off !!!

jeebowhite Posted November 15, 2013 Share Posted November 15, 2013 battery is a possibility, but the turbo should be spooling more than 25% Have you put a multimeter over the battery? Quote Link to comment Share on other sites More sharing options...
