BMW Z4 2015 Retractable Hardtop

wiley · 02-22-2019, 11:31 PM

I have a problem with my retractable hardtop that works a few times then it will stop once it's up. To make it work I have to remove the positive cable of the battery and then place it back. Only works for a time then stops again.
Anyone can help I would appreciate it.

Is it still under warranty?

Thanks for contacting me.
No, it isn't.

Try replacing the 2 orange relays located near the pump

Thank you for your input, once I go in for my oil change I will have them check it out. Wish I could do my own work, but but sad to say I can not. I would think more owners of this series would have had the same problem as I do.

It was taken from a broken roof I was able to repair last week.
If anybody needs some kind of support regarding the roof, feel free to get in contact with me or head over for a visit in Munich, Bavaria.
