54 How can I install programmable wiper control in my car like the new cars have?
A: The programmable wiper control allows you to program the interval time.
Because VW does not like to add new knobs and wires, they have put all
the control in the relay in a type of teach and play back mode.
If your old windshield wiper relay part number is 191 955 531,
then you can swap it with the programmable unit: 357 955 531 or
the new number 1HM 955 531B for under US$40.
Note, APS sells these control units for about 10US$ less. The APS part
number is: 25-955.531
The same unit is apparently also directly available from Bosch.
It is called the 'Easytronic' wiper module and provides a 2 to 45 second
wipe interval. The Bosch part number is 0 986 335 058 (at least in the UK)
and is available from all Bosch stockists.
To program is easy: Push down on the w-w lever, have it wipe once, bring
it up and wait until you need to wipe again, then push it down.
It'll use the same wait interval! Very clever, but not obvious.
