Ummm... Battery?

Hey guys, hoping this is a battery issue.

Went to start my car today got a clock from the rear near side and nothing else. Check engine light on. I connected the OBD, No codes detected. I know you can't answer conclusively from this evidence but if anyone has had a failing battery, could this be a sign of such? Every car I've had previous would show signs (interior lights dim, show cranking before giving up). This just said 'click' and everything else looks fine.

I presume it's fine to try to jump start it just to have a go even if I'm not sure it's the battery? I want to have a go before it dies completely and I need to try the rip cord...

Dead battery all day I think. Get a new one on order, once they're gone they're gone!

Is there any reasoning as to “when they’re gone” on an Evora 🙄 as on my previous cars I found that a battery could be revived/life extended sometimes for a long time by putting it on charge for a decent duration.

You're just postponing the inevitable and seeing as they tend to rocket off a cliff rather than gradually decline, you're risking being stuck somewhere inconvenient with no power for the sake of £75.

Be very careful if you try to jump start an Evora. If you have the key in the ignition while you apply outside voltage, you can corrupt the ECU and get a (fatal) "COMMS ERR". 

The way to avoid this is to keep the key away from the vehicle until you have the jump box connected. Then  proceed to grab the key and start the vehicle. The ECU is extremely sensitive to voltage spikes and is powered up when the key is in the ignition in ANY position.

Originally, this error would cause you to have to purchase a new and very expensive ECU. However, the ECU can now be recovered by Lotus but is still a very costly procedure.

It has happened to several owners over here before it was learned what had actually caused the issue (all common with owners trying to jump start their vehicles).

Thanks, that's gold information (like your car!). Big thanks for the heads up!
