OK, so I went to start the 7 this evening – turned off immobiliser, turned the key (ignition light on, pump buzzed as usual), pressed starter button…….there was a faint click from the engine bay but nothing else happened. This has never happened before in 12 months of ownership. I had a previous 7 which had the K click so I tried rocking in 3rd gear and had another attempt but no change. I pressed the fuel cut-off switch under the bonnet but no change. I have checked all the connectors but nothing seems loose. It worked fine yesterday and the day before, and last week, and nothing has changed since yesterday (well, something has but I don't know what) so I am really confused . What am I missing? I have searched through some similar posts and they generally point towards batteries/fuses/earthing/ECU issues. I tried again but with the headlights on to see if they dimmed but they didn’t but not sure what that proves. Beginning with the simplest, I have put the battery on a trickle charge overnight and will try again tomorrow morning. In the meantime, if anyone has a please let me know! Thanks.
