Situation:
Government regulations require vehicle manufacturers to monitor the fuel evaporative system for the loss of hydro carbon vapors into the atmosphere by performing a vehicle self-check of the complete system while the engine is in operation.

In the event that a leak is detected within the system that may result in the release of HO vapors into the atmosphere (Example: A loose or missing fuel filler cap), the check Engine " light will be illuminated upon the second consecutive occurrence of such a fault. If the filler cap is reinstalled the "Check Engine" light will go out after the system has gone through a self-check three consecutive times without a fault being detected.

Correction:
In order to raise customer awareness, BMW is asking that the following labels be placed on the fuel filler cap and/or on to the fuel filler door by the Service Advisor whenever a vehicle listed above is at the retailer for service.

Label # 1 (P/N 71 21 2 122 552) - "Loose or missing cap will activate check engine light"

If not already present, place on fuel filler cap.

Label # 2 (P/N 71 21 1 184 663) - "Do not refuel while engine is running!" If not already present, place on fuel filler door.

NOTE:
Many of these vehicles will be reprogrammed due to a Service Action (refer to S.I. 12 10 97 dated 3/98) please place the labels on the vehicle whenever the vehicle is in the shop.

Each dealer will receive an initial quantity of 200 labels per part number. Additional labels can be order through the PDC at no cost in packets of 200.
