So, just bought a C4 GP 2014 Exclusive Plus with 74k on the clock from a Citroen garage. Got a few issues I thought I'd ask about here before I went back to the garage. First off is the indicators that work fine except for the fact that they make no sound at all when activated. Is there a setting for this or a simple fix? Second is the right rear suspension makes a continuous, god awful squeaking noise when driving at any speed. I can live with the odd creak and rattle since it's not a new car but this is migraine inducing. Is this a known fault and would it be covered under the Citroen extended warranty that I took out? Lastly is the ECO mode, which after lots of long drives to recharge the battery, never comes on. At best it flashes three times and then goes away without actually activating. I've driven my father in laws C4 and the stop/start feature works no problem. Is this likely a tired battery or alternator issue? Just to add, I tested the battery with my voltmeter and it's only sitting at 12.35v. Mark
