I'm looking for a "known good" glow plug relay that has the "after glow", and no Gee-Bee not one from Ebay. Dealer wants $140 and up for them.
PN 191 911 261B
Does that have one really large pin? Im showing 038-911-253 VW or Bosch # 0281 003 013. I looked up a 98 Jetta. I can do the Bosch for 50 + shipping.
A caution: on an MK3 the glow plugs are controlled by two separate pieces:
1) a control module: listens to the coolant sensor, drivers door, makes decisions about how long the plugs should be on, drives the light on the dash etc
2) the glow plug relay: takes on/off instructions from the control module and switches the 60 amps of current safely
The control module is a large module with about 16 pins and in and of itself not able to drive glowplugs. The glowplug relay is a small 4-pin device that has two large pins to handle the current.
Picture of both of them side-by-side on my website about 3/4 of the way down this page:
