Key Fob Roof Down

[Smartbear]

IT HAS A RECHARGEABLE BATTERY? No way! I've just been using regular ones in mine! Haha!

Hi, some models use normal batteries-comfort access ones I think?

You could confirm that either way but sitting in the car and trying to open the roof in the normal way with the centre console button...if it works it's not a battery voltage issue. I can't help thinking it's a key issue..maybe the battery in the fob is not holding charge well so you get enough power for a blip (like and unlock etc) but the sustained signal required to open the roof kills the battery pretty quickly. Bit of a guess but plenty of places will replace the battery for you included the well respected forum member ducklakeview for very little cost.

Not the replaceable type,they are supposed to be rechargeable when used in the ignition,have tried both and it still does not work.They look like sealed units ,key fobs that is.So how do you charge them up long term without driving to Scotland and back.Been told to attach trickle charger to car battery then put key fob in ignition in the on position and leave it for a good long time like over night maybe and then it will be charged up ,is this true?

Don't want to hijack the thread but if your key puts the roof down when you press and hold the unlock should it also go back up when you press and hold lock ?

Am I missing something or needing to set something to make the close work ?

TIA,
Charles.

No close option as std I'm afraid. You need an aftermarket module for that.

Not cheap - but worth it in my opinion. Keep your eyes on the for section.

Both key fobs have stopped opening the roof.Both key fobs do everything else.So what is happening to my car? Top button on both fobs unlock the car middle button locks the car ,bottom button opens the boot.Car battery fully charged up using CTEK on recon program.From now on I will just have to open the roof from inside the car instead of the flash way of walking towards it,so be it.

Or comfort access option.

Can this be retro fitted ?

Probably. But expensive. New door handles, column, key etc etc. May at well just buy a smart top as others suggest.

(Unless you fancy a project) .

No thanks !
I’ll stick with the Smarttop module :

I bought my car at the end of the production run last year so I was very choice restricted and had to accept a pre ordered car - fortunately it had most of the toys I needed but not comfort access or headlight assist!

Don't worry. The headlight assist on the Z4 is absolutely rubbish. I considered asking for a refund on the cost. Yes, it works, but it is crap.

Had my e89 in at the local dealers today for an oil and brake fluid change. Both my fobs now don't lower the roof, apparently the fob needs reprogramming... an hours labour £90, think I'll add some pennies and get a smart top instead!
