OK so I finally got round to doing rear discs and pads on my Macan GTS and it is very straightforward provided you do it in the correct way. So usual of jacking up rear and removing wheels. Turn ignition on and release EPB then switch off ignition. Parking brake will stay off. Remove wear connector by tilting and turning 1/4 turn. There is no need to remove connector to the EPB motor but you can if you want. Next remove the EPB motor - 2 smallish torx on rear. Now this is the important bit - before you do anything else like trying to remove calipers etc you need to put the caliper into service mode. You do this by turning the female torx on the back of the caliper clockwise until it stops. No need for a wrench as it is only finger tight. you do NOT need a computer/diagnostics to do this - another OPC myth! Once you've done this the piston caliper can be pushed back. Note it is not a screw type and it's easiest to do this with the old pads/discs still in place. If you put a screwdriver down through the top of the caliper at the "U" section and pull it towards you the piston will retract quite easily (remember to remove brake fluid reservoir cap). Once the piston is retracted fully back it is a simple case of removing the 2 bolts holding the caliper and lifting it off the caliper carrier along with the pads. Again no need to remove the caliper carrier and if you are replacing the discs you can still get the old disc out and the new one in without removing the carrier. Remove all the old parts and replace with new pad spring carriers, new pads (and new discs if required - my rear discs and pads were more worn that the fronts surprisingly) and new wear indicators (lube as required). Refit the EPB motor. Now here is an another important bit. Once you have everything in place and tightened you need to apply the EPB before you do anything else. You will hear it whirring in the same way as usual when you apply the EPB but it will take a lot longer - up to 10-15 secs. Now you can push the brake pedal which should be firm. I did this cycle a few times just to be sure. Refit wheels, torque etc. Fire it up and drive forward gently and apply foot brake - all should be good. Also drive forward and apply the EPB - it should go into emergency brake mode and bring you to a halt. Finally check the "hold" feature is working by applying foot brake when stationary - again you should hear the EPB working.
Once I had worked out the correct way to do this it only took about 15 mins each side. Sorry but I didn't take photos but hopefully this is detailed enough.
,As for parts the caliper is VW/Audi TRW and the old pads that came out were TRW pads so if you use TRW they will be same as factory fit/OEM. I fitted Ferodo. No marking on the discs that came off but I used Brembos which have painted edges so don't rust and look as bad as OEM Porsche discs once rusty. All parts were from buycarparts.co.uk in Berlin - for just £133.00 as follows

Brakes are one of the few things left these days that a confidant amateur mechanic can attempt. Great write up and very helpful
