I had an issue with a D4 where we though it was the parking brake switch and indeed replaced it, and a couple of months later the same issue occured of the electronic parking brake not releasing. Fortunately I had Vagcom with me and was able to tell the handbrake to release itself!
On further investigation it turned out to be loose wiring / connections where the wiring harness went into the brake module in the LH side behind the boot trim. This was sorted out and all has been fine since - worth a check in case you are getting intermittent connections causing issues
