hi guys, I drive a 2012 seat leon SE copa 1.6 TDI, about 14 months ago i had to have the EGR valve replaced. However this week the EML light came on and the flashing glow plug light has also appeared. When i plugged it in to find the code it was P0403 EGR flow circuit malfunction. i have been looking online and it appears it could be loose wires or fuse that has went, but does anyone know if i could put a cleaner through it which my be the actual cause, since the valve is only a year old.
