I don't doubt your information but perhaps what the parts catalog refers to is ambiguous or ???  |
A clarification: EGR was added to your motor from engine serial number 181462, which puts it just about start of model year 1990, but there was a handful of earlier, individual motors that got the EGR. Maybe those were technically considered MY 1989, although I tend to doubt it, b/c the on-board diagnostic coupling (X11/4) with pushbutton switch and LED in 1988 and 1989 models only goes to 10 pulses, none of which denotes EGR. In MY 1990, EGR was added as one of the stored faults (12 pulses). Maybe there's an owner out there with a 1989 that has an EGR and can chime in; never heard of it though.
