Introduction to Inspections
What are BMW inspections?
If you're new to BMWs, you'll hear a bunch about "Inspection I" and
"Inspection II". These are essentially the same thing except the latter
incorporates some more-costly items. Inspections and other services are performed
when all five green LEDs of the service indicator have extinguished, or (roughly)
every 18000 miles (for the E36 vintage car -- newer cars typically have longer
Inspection I and II alternate (e.g. the first inspection is an Inspection I
and occurs around 18K miles, the second inspection is an Inspection II and occurs
at roughly 36K miles, the third inspection is an inspection I and occurs at
48K miles, etc.).
The interval between inspections is particularly relevant when BMW is paying
for the inspection. The reason? They're a company focused on P&L and want
to make sure you don't do Inspection I too early because then they might have
to pay for Inspection II if it occurs under the 36K miles scheduled maintenance
(recall that I said the inspections occur at roughly18K mile intervals).
Therefore, the only thing you really get for "scheduled maintenance"
is a few oil changes and an Inspection (about $600 worth of work at 2001 rates,
provided your car has no major maintenance problems that aren't covered under
