Hi all, I have a 2014 diesel vrs and recently had the glow plug light coming on and going into limp mode. Had it at the garage on Monday where there was 5 errors, DPF, fuel pump and exhaust. Cleared them off to see if it happened again and if all errors came back or just one. Light came on again last night and took it back this morning. The only error there is a low fuel pump pressure. I also have a whirring noise on start up which I didn't realise could have been the fuel pump (my knowledge of cars is limited at best). Has anyone had this issue before or had similar experiences? Regards, Craig
