Dash warning low power functioning

[Johnlex]

Please can someone tel me what low power functioning means ???

 

I went to put the roof down on my 250c and this came up on the dash .

 

also the car is running lumpy and bit slow ?? Any ideas

Not much to go on but my first thought was the Battery, the roof motors take some current and ECUs don’t like low voltage.

I would check/have it checked.

I will put a voltage test on it, Battery isn’t old but car doesn’t move that often last time was Sunday long drive no issues.

Might be worthwhile John you getting one of those CTEK Battery refreshing gizmos. Because you don't use your car often the car still takes power to keep things in a state of stand-by. Must be enough to drain a Battery to a point where starting becomes an issue.

I’ve bought a brand new Bosch  battery same as before it was over 4 years old charge showed just under half 

car has more power and running like a dream 

 

So all sorted for now,

incredible what a new Battery can do and add so much more power it’s like I’ve added extra bhp 😂

Yes it's weird how a new Battery affects a car. But still worthwhile getting something like a CTEK.

I will look into it 

yes new Battery 🔋 adds so much to the car
