ML270cdi stalls when pulling uphill then stalls when you touch the brake lightly
when it stalls sometimes it is just a hesitation but my wife had it completely cut out uphill with horses on board towing dangerous , no error codes , Mass air sensor replaced due to error code two months ago, air intake plastic pipe to turbo was cracked and repaired 1 month ago, will do it predictably by touching the brake uphill but not on the flat ????
