Roof is now working again - i think it was the battery. I read that the car only charges to 80%, and a battery trickle charger wont reach the last 20% charge. After a few drives it works fine again, i suspect a bit like the stop start, it is one of the systems that will not operate unless there...

It wasn't making any strange noises, sorry for any confusion. I have also checked the last service sheet and the panoramic roof was lubricated by mercedes last month at part of a B service. The only thing that i noticed today is that there is a light on the button that operates the roof, and...

I agree, i can only go by what i have read on other forums, where suddenly one day the sliding roof / glass stop working, then at some point in future it starts working again. Fuses have been checked, Aux battery is good voltage, engine battery had a warning for being low but even though it is...

Its not that - checked voltage and that is 12.8 volts, so must be main battery, as stop start has stopped working too. New AGM battery time i think.

I think what might have happened is due to playing with the gadgets etc in the car with only ignition on, the Aux battery has gone down. Until that is charged up, the sunroof will not work. Whilst i have charged the engine battery, perhaps there is a link between the aux battery and the sun...

Yep

Yep

the button doesn’t move forward though, it’s at its stop point if that makes sense. It presses up, it pulls down, and it pushes back. I know how it works as it worked before, but there isn’t a way to push it forward.

I did, the button doesn't go forward though in the car, it goes up, down, and back. Yet the reset video has the guy pressing it forward. Will have to take it on to mercedes, as it has a mercedes warranty. But thought i would see if i could resolve it first as the next appointment available is...

Had a go but wasn’t clear what the procedure was. Checked the fuse and that’s fine. Am convinced it’s battery related but surprised it hasn’t started working after a charge up using a battery charger overnight. It was working fine; but we’ve spent a bit of time with the ignition on, not engine...

Can’t open it to check the tracks ?

Sorry typo! 85amps

Tried with engine running, no change. It’s an odd one as it was working just fine. Think a new battery is in order anyway so will see if that resolves it. Has a warranty so worst case will take it in

No such luck charging overnight, got battery to a decent voltage, but still no roof working. However have read this happening to other people, and maybe it actually needs a new battery as it was only showing 12.1v after a quick drive. There’s also the aux battery I understand, and the stop start...

Thanks both. had it on a trickle charger but it it’s only a small charger for a motorcycle battery, looking at the battery they’re 850amps so assume that will need something bigger to charge it. Have checked just now and says 12v battery warning check owners manual, so maybe this is the issue...

Hi all, recently acquired a 2019 a200, it’s an auto 1.3. I know very little about these cars. The I think it is a w177? The panoramic roof worked fine, but today we tried to move back the blind after closing the blind, and it doesn’t do anything , nor does the roof retract. I have checked the...
