    So weird, mine did the exact same thing over the Christmas period. Hadn’t moved for 4 days and a horrible clunk as I drove away. Thankfully doesn’t seem to have caused the damage you experienced but have to agree seems like the pads have changed.

    My brake disks on my MK2 Cupra always rust up quick and bind like you guys after washing. I'm going to get some Bilt Hamber Atom Mac which you spray on the brakes to stop the rusting which should stop them sticking.

    I've figured out how to lessen the stuck brakes the next day after washing car and putting away, leaving the hand brake off has improved the situation no end, I have squeaky brakes for a few moments but can live with that.

    to leave hand brake off turn engine on, disable "auto" then take hand brake off, turn engine/ignition off. I would only recommend you do this in garage though! mine is DSG too so in park.. just remember to put it back in "auto" on 1st drive!

    I always leave the handbrake off, and have done for many years, when my car’s parked in the garage to avoid the brake pads sticking to the discs when they’re wet.

    We were on holiday for a month mid December to mid January and it was only whilst away I realised I'd left the handbrake on. Last time (Nissan) I left the handbrake off and chocked a wheel (drive slopes backwards). On return handbrake button off, no sticking and drove up the drive no problem - phew.

    So the best way to use an electric handbrake is to disable the thing?! :0. Gota love progress...

    I did not know this when I was swopping over Summer/Winter wheels+tyres on my daughter's Leon Cupra, so I just took a dummies way round this and left the ignition key in the lock and the driver's window open (just in case) and so the car seemed to remain "annoyed" while I was able to rotate all the wheels freely, I'll know better next time!

    My 2011 Audi S4 has its auto hill hold feature defaulted to OFF, which has its advantages, my wife's 2015 VW Polo has no option there, which can get annoying at times when stopping on a slight slopping bit of road - I did notice when once being a passenger in my daughter's Leon Cupra that the auto hill hold defaulted to ON, same on most newish VW Group cars with electric handbrake, which in some circumstances and/or with some dreaming drivers, means they have "auto handbrake" - so that is one thing less to bother about or consider, ie dumbed down driving - so yes @Mr Pig - "progress" indeed!

    So automatic handbrakes are good for people who are not paying attention and can't operate a car properly? That's great! For the rest of us, they're shite.

    On my cars, Leon mk3 and Golf mk7, I have it always off regarding auto hill hold. No problem, just use the E handbrake when I want, every day exempt when the car is new washed :)!

    You must use it, otherwise it will be out of function in time I suppose…

    I never ever used to bother to use the "hill hold" or "auto handbrake" on my 2011 Audi S4, until I read that there are just too many early life failure of the electric handbrake units, and the either official line from VW Group or "forum speak" line was - "when and/or if possible always enable the auto handbrake to hold the car instead of operating the electric handbrake, as this reduced the number of uses of the electric handbrake" - use the electric handbrake as a parking brake only - now that did not give me much confidence that these electric handbrake modules are fit for purpose long term.

    So, typically I've started to enable the auto handbrake function and use that to hold the car while on the move, or if it interferes with my progress, I disable it, for those who do not know about this at all, on some VW Group cars the hill hold or auto handbrake function works by closing hydraulic fluid valves so that the brakes remain ON on all 4 wheels by virtue of the trapped hydraulic fluid, the electric handbrake is just an electric motor in both rear wheels, if you doing anything that risks your life, like taking the seat belt off or opening the driver's door, the electric handbrake automatically replaces the hill hold function, similarly when the engine is switched off, the hill hold automatically gets replaced by the electric handbrake function. Some cars ignore the driver's seat belt being removed and some lower level cars with mechanical handbrakes, have hiil hold lite which can not be disabled and only holds the car for many 3 seconds after the footbrake is released, good enough though once you are used to it.

    I had no idea that the electronic handbrake function and auto hold were done in a completely different way by the car - thanks for sharing RUM4MO.

    I for one let the car do its thing, there has been the occasional clunk pulling off the drive but nothing that sounded like it was doing any real harm - and I do like the convenience of the car holding itself still in traffic.

    Of course there is a possibility that VW Group have managed some way to cheapen this, but I'd doubt it, I tried to check how it worked with my mate's 2018 VW T-Roc but I gave up after he kept opening the driver's door and couldn't follow instructions!
