Had it a week , it started missfiring so i took it back , they cleaned the EGR & has been fine for 3 weeks . Now the glow plug light is flashing & it goes into linp home mode . Going to phone them tomorrow , but want to know legally where i stand, before i do . Paid the full screen price cash & they took my old Zafira in part ex. The garage was reluctant to look at it last time thats why i need advice. Thanks
