Draining battery

[Delboy]

No I diagnosed mostly by checking they work correctly.

They comfort access should work where you get the car to unlock by putting you fingers under the door handle but not touching it.

If you need to pull the handle up to unlock then pull again to open its not working correctly.

For locking it should lock simply by one push of the button on top, if it unlocks again or doesn't lock at all then again it's not correct.

I find if any of these problems present themselves then you will find the battery will go flat as the spurious false signals to kessy wake the car up and drain the battery.
