I've got a bmw 525d automatic. Have some heavy dark smoke coming out exhaust. I have cleaned the EGR work fine.
Friend told me to check the hose from turbo connection to the EGR and see if there is any cracks in. Checked.
When i'm driving up to 2300 and up smoke is comming out heavely and power go down to.
Anyone can tell me what tit could be?
