Hi team, i hope this message finds you well. I had my vacuums lines replaced 2 weeks ago along with rear turbo. ( wastegate was stuck in the open position) The job was completed by a BMW dealer under warranty, so it should be good workmanship ( we hope so anyway ) The car drove like a rocket for the first 2 weeks, then i noticed a slight loss of power, exhaust slightly louder, car running slightly sluggish. no engine lights have come on, no fault codes from Torque engine management diagnostic tools and MHD flasher NOTE: Toruqe app real time boost psi and vacume readings do not go into positive, is this normal? 335i.pdf335i.pdf I dont have anymore to evidence to show the workshop. and they are hesitant to help further Is there anymore testing i can do or any advice from fellow BMW owners to help build a case to present to dealership. any advice would be appreciated. (I have attached a copy of invoice notes, to give a clearer picture) regards
