Roof will not open without engine running

[Joopx]

My roof will not open without the engine running. It also doesn’t work with the fob.
With the engine running it works perfectly.
Battery has 12,06 Volts.

I bought the car only a couple of weeks ago, so not sure if it was always like this.

Any ideas?

Usually this is a low car battery level.. try doing it just after you've driven it on a long ride..

Agree that sounds like the battery. Should typically be 12.5 to 13 volts after a run. Alternator should be kicking out around 13.5v

Thanks guys,

Today I did a long ride. Still no roof without engine.
Guess the battery is getting old..

Have the same thing on my 2011 2.31.
Bought a trickle charger from Argos £20 and I leave it on overnight once a week and then roof opens with key. Even after a long run it's often not enough to charge without trickle.

Therefore you must have a problem with the alternator not charging the battery or battery not holding the charge.
When i put my code reader on i was surprised the voltage show with engine running was 15 volts.
Have these cars been properly coded if they ever had replacement batteries.
If the car is several years old i thinking it's worth investing a new battery, just for the convenience.

A couple of weeks ago out of curiosity I put the battery on charge, and it took 10 amps... The car starts perfectly and I have no issues whatsoever. The car is used almost daily so maybe if I didn't.... It's a newish battery I think but food for thought maybe.

Yes I suspect I'll need to replace sooner or later.

New battery fixed it. Thanks!

I had the same issue - got a new battery and it only fixed it for a week or so. Are you still not having any issues since the new battery?
