Hello,
does A5 (Driver Assistant) have an SFD lock ?
I can't make any changes to the Adaptation sector.

I'm trying to do the rear pads on my skoda. When trying to use the open function it's saying problem. With SFD. Any help would be appreciated

Lewis: Hi. I don't know how to fix the problem of unlocking a brake module with SFD "to do the rear pads on my skoda".
I'm surprised that this is required at all for a routine procedure like changing brake pads - I assume that you have tried opening the calipers using OBD11 without attempting SFD unlock.
So, if you can't find a solution to the SFD issue -maybe consider NOT using the recommended procedure via the brake module?
The problem that is encountered when fitting new pads on cars with EPBs is getting the caliper to fit back over the new pads because of the increased pad width. The official procedure using a diagnostic device to operate the EPB motors solves this problem in 2 x parts as follows:
- Part 1 : the "opening procedure" activates the electric motor to retract the caliper-piston so that the new pads can be installed
- Part 2 : the "closing procedure" re-calibrates the caliper-piston position to suit the new pad thickness after the new pads are installed
However, it is possible to achieve the same result by manually winding the spline that open/closes the caliper piston. To do this for Part 1, do the following (note: the pictures below are from a Golf mk7 - I assume that it's similar for this car): - Ensure that the EPB is NOT engaged!
- Remove the caliper housing and fit the new pads into the pad-mount cradle
- Before refitting the caliper, remove the electric motor from the caliper housing (remove the 2 x bolts - see "arrows" in picture below). This will reveal the working parts of the OPEN/CLOSE mechanism
- With the motor removed, you should see that the "multi-spline" part is secured to the "fixed" part of the OPEN/CLOSE mechanism by a "C" clip as per the picture below:
 - To manually open the caliper, grab a T45 socket and a set of multi-grips. Using the grips, hold the fixed part of the OPEN/CLOSE mechanism.
- Then insert the T45 socket into the multi-spline and manually turn by hand - you should see the rubber-boot end of the piston retract as the multi-spline rotates (reverse the rotation direction if the piston-end doesn't retract)
- When the piston is retracted fully into the caliper housing, refit the electric motor back onto the caliper body and bolt the caliper back onto the brake-pad mount
- In car procedure post the completion of the pad replacement - Press the brake pedal repeatedly until the pedal is "hard"
- Activate the EPB using the center console switch (you should hear the EPB motor activate). The calipers are now re-calibrated for the new pads
- Deactivate the EPB
- Turn-ON ignition and test EPB again
Of course, the recommended way of brake-pad replacement is ALWAYS the "official" method - but!!!!
