Zest 7 Posted September 13, 2018 disconnect, leave for 5 mins and reconnect battery? Share this post Link to post Share on other sites

I'd sooner cut off a limb than disconnect a Battery on any MB, later the Car the worse the resulting grief......................... Takes half hour to go round checking and normalising everything that won't work correctly afterwards Share this post Link to post Share on other sites
Dave2302 387 Posted September 14, 2018 Hi, Pre Safe Message can be caused by a problem in any number of systems, which will then trigger it. The only machine to diagnose this is SDS, Snap On and other generics will likely lead you up the garden path because they simply do not see all codes in all Systems. Don't go the guesswork parts darts as I'm sure you know that will likely end in a huge un necessary expense Xentry (MB SDS), will see all faults, and has guided diagnostics to lead the operator to the problem, or at very least the correct seat in the stadium A good Indie with SDS, is needed ............................... I'd have you an answer within an hour Share this post Link to post Share on other sites
