S4 Cab Roof Problems

[m.jolley]

Hello there,

I've got a problem with my 55 plate S4 Cabs roof. Yesterday I decided to put the roof down for the first time in months, I operated the roof button, the windows lowered and the front of the roof unhitched from the windscreen. It proceeded to move back ever so slightly, then stopped. Now the roof light is flashing on the dash, the roof isn't secure and will not close.

I followed the guide on youtube and manually took the roof all the way down, then put it all the way up again, hoping that it would reset the system. It still has the same problem of unhitching, then stopping part way through. Now when the car starts up, the roof light will flash for a few seconds before going off.

Is there a possibility that there are components which could have failed after months of no use?

Any help would be greatly appreciated.

you need to get it on VCDS to see the fault codes
it could be anything from a sensor to the pump

did you do the manula reset more than once ?
sometimes takes 2/3 goes

hi there, i know this is an older post but hoping you can assist.

Im having some soft top roof re-set problems. We initally thought it was the motor or the pump but both seem to be working. could it be that i have to do some sort of factory re-set. we have tried to manually reset the top by taking it up and down a few times. any suggestions?

Hello,

Please describe your roof problem and symptoms to me or what happens when you try and operate the roof.

There are mentions of a "factory reset" which involves opening and closing the roof manually, in essence this does not cause the control unit to "learn and store" the new values but just ensures all the micro-switches are in the correct position, especially if one of the locks is not locked correctly. So yes make sure your storage compartment and top lock is locked correctly (unlock it and lock it again making sure to only remove the manual key when you have reached the stop position.

P.S. its probably better to continue this topic on the Roof Repair Guide Forum as it get a significant higher number of hits !
