I know there's probably not a good time for any fault but a week an a half before Inters definitely isn't a good time! Anyway, has anyone had this fault before?: Ross-Tech says: 17648/P1240 - Fuel Injector for Cylinder 4 (N33): Open Circuit Possible Symptoms MIL On Poor engine performance Possible Causes Fuse for injector Wiring harness issue Failed injector Failed ECM Possible Solutions Inspect fuse for injector Inspect wiring to and from injector, see repair manual Ohm test injector, replace if needed, see repair manual I'm running 1 year old Bosch 550cc injectors so I don't think the injector I the issue. I've swapped it over with cylinder 1 to see if the fault follows. I'm guessing wiring. I assume the injector wiring will break down in the same way as the coil pack wiring over time? If anyone has seen this before can you give me some advice? Thanks.
