Me again. Feels like I'm always finding something :S

So, my battery is on the way out so I have ordered a new one. I hooked up Carly (as I already had that for a Mercedes so it was the free version) and that informed me that the battery health was very bad, charge level at 65% with a self-discharge of 9.54% and I'm not sure if its a coincidence, but randomly I then got the four red squares (two in each corner), front and back with a long beep. I initially thought it may be because the car is dirty so I washed the car but the problem still exists.

I know its troublesome to diagnose without a fault reader, and I don't have any codes, so I am looking at purchasing https://www.design911.co.uk/p/icarso...rsche-cayenne/ to help in that regard, but based on the information and how randomly it occurred, any clues? I have not had a chance to investigate, going to start with checking the fuses and then my suspicion would be the park assist module...

 

See if it comes back when you change your battery. Most modern cars will shut off non-essential systems when the battery voltage drops too low. If it's still an issue, then you'll need to do a "handover" with a PIWIS so the car can re-discover all of the modules on the CANbus.

 

Yeah that feels like the mos logical step. Hoping I get some time and decent weather tomorrow to swap it out

 

Strange, all good today. Not that I am complaining

 

Definitely sounds like a low voltage issue then.

 

Yep seems that way, which is a relief
