Hello my girlfriend recently brought an Adam to learn to drive in and since driving it Iv noticed when stationary there is a clicking coming from the engine every 20-30 seconds almost like something electrical switching on and off. It’s quite loud and when I had the bonnet open the engine jolts a little bit when it happens, Iv got no idea what this is can anyone help?? 2013 1.4 Adam Jam

Are you sure it's not just the aircon? Try and see it it still happens with aircon and blowers turned off.
