There are three switches that are connected to the two pedals of the brake and clutch pedal cluster for the manual UrS. Each of the two peddles gets a mechanical/vacuum "ventilation valve" that is part of the cruise control system and is used to disengage the cruise control the millisecond that you touch either the brake or the clutch pedals. These switches (PN 811907343B) are Items 39 in the first diagram and Items 11 in the second diagram. The brake pedal also gets an electrical (two pin) brake light switch (PN 443945515), item 40 in the first diagram. (Note: UrS4 and 95 UrS6 brake light switch= 443945515; but 95.5, 96 and 97 UrS6 Brake light switch = 4A0945515A)
Adjustment of these switches will involve spinning them in the Item 38 (PN 431721283B) clips (hoses and wires disconnected) until they just click (or release) when the pedals are touched and then reconnecting the hoses to the ventilation switches and the electrical harness to the brake light switch.
