Hi everyone, Having a really annoying problem with my 3 year old Copen. This might be a bit long-winded, but I'll explain what happens on a normal day, then explain what's happening this week: 1 - Press unlock button on keyfob (Cobra 3 button type), doors unlock 2 - Put key in ignition, turn to position 2 (where all the warning lights come on). At this point there's an audible 'whirrrrr' from the rear, behind the driver's side. It's always done that so I'm assuming it's normal, it sounds like something is being 'primed' or switched on mechanically. (If I leave it at this point for longer than 30 seconds, nothing happens in the next step and I have to press the unlock button on the remote to disable the immobiliser) 3 - Turn key further & let go. Starter motor spins, engine starts, happy motoring ensues. Now, in the last 7 days I have been having intermittent starting problems: 1 - Press unlock button on keyfob, doors unlock 2 - Put key in ignition, turn to position 2. At this point there isn't any whirring noise from the rear - I don't hear a thing. 3 - Turn key further. Starter motor spins, but engine doesn't fire, happy motoring doesn't ensue. Lights & everything electrical works OK, I can retry several times for several minutes and it still won't fire so I don't think it's a duff battery. If I keep trying every couple of minutes it won't fire, but after 10-15 minutes I hear the familiar whirring sound from the rear and it jumps into life! So what do you think? What is the thing making a noise behind the drivers seat, does that have anything to do with it? I called the RAC out last Friday and he couldn't get it to start either, but after 15 minutes of trying he got it going, but he doesn't know what he did. We took it to our local garage and left it with them for 5 days, but it started every day first time for them! Also (and this may be coincidence) my reversing sensors no longer work. They used to when I engaged reverse, but now they're silent. Thanks in advance for any help/advice.
