I have a fiat stilo 1.4(2004) plate.
It had an intermittent issue with the "car security manager loose connection" and the car wouldn't start sometimes, But when shaking the fuse box/power distribution unit just behind the battery the car would start.
It then got progressively worse up to the point where as if the power distribution unit even gets nudged slightly (like when you set off) the car cuts out completely.
I did have the AA come out and take a look at it and the fault code they read was "power distribution unit fault", which leaves me in a bit of a predicament because you can't just buy a spare one as it is programmed to the ecu.
Which means I would have to buy a second hand ecu + power distribution unit off the same car, would there be anything else I would need that is uniquely programmed to the ecu apart from getting the key re-programmed ?
the power distribution unit in question (ignore the red circles, it's the best picture i could find of it)
