During 1991 a new style drain plug and copper washer were introduced into production. The drain plug has a taper at the bottom of the thread, and a
much larger flange surface area. The washer has larger inside and outside diameters than those used previously on the B234 Engine.
Note:
The old style drain plug washer, PN 75 22 709, should not be used in conjunction with the new configuration drain plug. Its inside diameter is
not large enough to clear the taper of the plug.
Dealers should order the new washer in anticipation of servicing the first cars with this feature.
This information has not yet appeared on the microfiche, some recently imported vehicles have the new plug and washer. Note that it is not possible to
give a precise chassis number break for cars with the new plug/washer combination.
