Found the battery completely flat this afternoon, after first spotting the Tyre Pressure Monitor light.  All tyres fine, so no apparent problem there.

 

Battery is only 18 months old (as is the Yeti) and has been looked after with a Ctek charger.

 

Now the TPM light is flashing, which indicates a fault - "If the warning light flashes , there is a system fault."

 

Any thoughts please?  Is there a likely link between the strange and sudden flat battery and the flashing light?

I've just read a thread somewhere where the poster had a dead battery.... and the first sign of this was the TPM indicating.  So getting the volts up should sort the problem.

Have you tried pressing and holding the TPM button? It should beep when it's reset.

Battery now fully charged (thanks to the excellent and extremely practical CTEK charger) and although the TPM light continued to flash for a short time, it had cleared itself within half a mile.  Still puzzled by the sudden flat battery, but it's now showing as fully charged, and it seems to be holding it.

 

I'll check it out properly under load with a tester due to arrive on Sunday from Amazon - don't trust it at the moment, but reluctant to shell out on a new one unless absolutely necessary.  I'll make a warranty claim if it needs replacing - that should be interesting!   :sun:

You shouldn't have to go out buying diagnostic kit - if the battery has lost all its charge and the car is still under waranty just take it back to the dealer to look at.  If the battery is duff they'll replace it under warranty.  We had the battery in our Octavia replaced under warranty when the car was just under three years old.

Good point.  Only £17 or so though, and it's a useful thing to have around for the future.  Will save a fair bit of time on what will probably be an unnecessary trip to the dealer too.  Interested in your warranty claim - no fuss on replacing it?

Yeah - no fuss, no argument.  The car had done the 'boing' noise and no interior lights.  I'd charged it up overnight but it was back to the low charge 'boing' a couple of days later.  Booked it in and it was returned the same day with a fresh battery.
