idle stablizer/its only another part- subject to--

old age
constant use for over a decade
heat
cold
vibration
the luxury ride in the back of a vanagon
with the super comfort suspension
1980's technology manufacturing and design
variations in voltage
etc.

As far as part nbrs.. how many vendors did VW use ??
So far i've seen two different manufacturers as far as I can tell
Siemans and Bosch-- as far as part nbr internally thay may have their
own production numbers-assembly lines nbrs, manuf plants- coded dates etc-
coded sub contractor nbrs-plan nbrs-who knows.

when ya get the schematic with specs- let me know-
keep your eye out for the "SAMS" manual--(now I'm dating myself).

NASA has put satellites in space that have had
far shorter life spans.

We all have thrown out motherboards, CPU's, memory chips
CDRW copiers-fax machines  TV's walkmans and other home appliances without a
second thought--

This is another Wear out part.

Since we don't have the service and testing manual for this item and certainly
not enough test equipment such as signal generators -oscillascopes- low
voltage soldering and desoldering equipment etc. 
Why worry about it- when the walkman dies do you take that apart and evaluate
it for repair??

Thats why it is a plug in replacement part..

I hate spending a buck more than most-so I too would like to repair my own
stableizer--

I also used  the DIY (do it yourself) hernia repair kit...
Gee ya really gotta know how to sew.....

Beep thrice when ya see me-I'll beep back and wave.

c'ya
