:D PSA – Pay And Display Ticket Machine

Pay And Display Ticket Machines are frequently occurring as part of the stationary traffic.
Everybody has probably had strong feelings about one of these about 500 "robber barons" in Düsseldorf, which are only serving you silently and loyal, and often enough that are scratched, kicked, hazed, and robbed.

In the context of pay and display ticket machines, there's a small crispy details, which unfortunately did not find its way to Düsseldorf. Just take a minute to read Wikipedia.

The german word you are looking for (convert umlauts to ae, oe, ue) should show you the way to the cache:

A = number of letters
B = sum of letter values
C = sum of digits of B
D = iterated sum of digits (down to one digit) of B

Go straight away to

N51° 15 . [B * D + A * C - 47]
E06° 45 . [B * D - A - C + 7]

Here you will come to know how this Mini-Mystery-Multi-Cache will continue.

If you are having absolutely no clue about this mystery, a small knight at the waypoint HELP may be able to help you.
