  • [Corsa C 2000-2006] management light and clicking noise

    bought 53 reg 1.2 sxi 2 months ago. never used it ,just a start up now and then to keep the battery up . car has done 1000miles per year for the past 5 years !. today I turned on ignition and engine light and spanner light both flashing and a clicking from top centre of the engine. this does settle and become erratic, car started ok. what do you reckon. cheers

    Give the battery a proper charge using a battery charger. Running the engine just means the alternator replaces the starting charge, it doesn't full charge the battery to maximum capacity. If you've not been driving it regularly then the battery has lost charge.

    If you test it with a multimeter it will still show 12v (actually should be 12.5v minimum)- but voltage isn't the same as charge.

    The clicking is usually due to the voltage dropping as you try to crank the engine and there isn't enough juice in the battery to maintain voltage.

      thanks but I don't think it is the battery. clicking noise is with the ignition on, not turning the engine over

        Ah - OK They usually make that noise when the battery is low on cranking. Wasn't sure from your post when it was actually happening.

        In which case best thing is to do the pedal test (look it up in the tutorial section) and check for fault codes. The top centre of the engine sounds like it's throttle body connected but sounds can be misleading as to where they're really coming from. See if you can track it down more accurately.

        On that year of C also check the ECU earth. Flashing EML is often an immobiliser issue but clearly not in this case as it's firing up. But the system is designed to trigger the fuel pump relay when you turn the key but before you crank the engine. It works by earthing the relay via the ECU. A bad earth can cause the relay to stutter which may make the noise you've heard. No harm running an extra earth just to check.

ID:	110562thanks for your help. if you can see this picture. if you look down from 24,25,26. there is an oval kind of shape with a hose running to right of it. well that is where the clicking noise is coming from. nothing to do with the red area in this pic

            Well that usually happens when the battery voltage is low - it may be starting but to be honest the first thing I'd do is to at least try giving the battery a good overnight charge.

            You say you bought it 2 months ago and haven't been using it, just starting it from time to time. That's always prone to causing battery issues. I had one two days ago with exactly those symptoms, put a spare fully charged battery on it - sorted.

                That's the throttle body. It usually makes that noise when the battery charge is low or there is a poor earth connection on the ECU or a bad earth on the engine or battery.

                The most usual is a battery at low charge so make sure you've properly checked that first. Then test the ECU for a good earth, people often add an additional earth for good measure. If you have good jump leads also try making a temporary alternative engine to body and battery to body earth to make sure it isn't a weak earth there.
