Customer complains of intermittent loss of power. Codes logged for fuel pressure regulator and low fuel pressure but no problems whilst on test so inconclusive..
Its had new lift pump and HP pump but still does it. I was going to change the regulator but she says its worse when the tank gets low. But she never puts more than £20 at a time in it so that may be a red herring.Euro's keep the bosch regulator on the shelf so are they a common failing?
