My '12 mondeo 1.6tdci has started to have issues when starting. These issues seem to be more prevalent when the car is cold (mornings) or has been stood around for a while (after work). It's only started in the last few days, but has got worse pretty quickly.
I've got keyless ignition, but I'm fairly sure its not that thats the problem, as it persists with both keys, and trying both keys in the key hole next to the steering wheel which I believe is the override for keyless if the car can't recognise that the key is infact in the car.
Normal startup procedure is power on, give it a few seconds to think about things / preheat, clutch down, power button to start, vroom vroooom. When I press the power button is just get a heavy sounding click, like a relay snapping closed. Everything inside the car seems to power down slightly to account for the extra draw on the battery, which is what it always used to do, but thats all I get. A click, and 2 seconds of everything being a bit quieter. It gives up trying to start after those 2 seconds and then I start the process of clutch up, clutch down, power button, click, try again.
The battery is a few months old and was the right kinda expensive one from ECP after they told me I wasn't allowed to fit a much cheaper flooded lead acid battery, so I don't think that the battery is the culprit here.
Battery key keyless ignition system
starter solenoid / relay
engine management faults (haven't checked)
Anyone had anything similar happen or got any other ideas about what it might be???
