hi i have just bought a kess v2 and am trying to do a dpf delete but it keeps saying generic error can anyone help please

Is it a chinese clone? If it is it will want pcb reworking and decent sd card files or it will never work properly, will do some cars but not all on list. Seen your other post saying it is bmw x3 3.0 2007,Mine has been fully reworked with decent components and good sd files with 4.036 fw and does these cars fine :mrgreen: , had lots of problems before this.
