SUBJECT:
Fuel Gauge Displays Inaccurate Fuel Tank Level

MODELS:
3 Series (E36) - Vehicles Produced Before 8/91

Situation:
Two separate, but related complaints may be encountered:

A) The fuel gauge displays an incorrect level; for example, the gauge appears to stick at approximately 1/2.

B) The fuel gauge does not show maximum level when the tank is filled.

Causes:
Two causes may exist for these complaints:

A) Left-hand side fuel level sender (P/N 16 14 1 180 517) sticking (causes gauge to appear to stick at approximately 1/2).

B) Pump nozzle shuts off prematurely when filling fuel tank, creating the incorrect impression that the fuel tank is full, and the fuel gauge does not show the maximum level.

Correction:
E36 vehicles produced prior to 08/91 and exhibiting complaint "A" as described above should have an improved left-hand side fuel level sender (P/N 16 14 1 180 517) installed. The improved fuel level sender bears a blue date code stamp of "9.91" or later.

Any vehicle exhibiting complaint "A" should be checked for proper alignment of the fuel level senders (refer to sections 16/12-3 and 16/12-4 of the repair manual).

E36 vehicles exhibiting complaint "B" as described above should have the breather line inspected for restriction and position. Refer to Service Information Bulletin 16 01 92 (3553) for this procedure.



Notes:

1) The Parts Department only stocks P/N 16 14 1 180 517 bearing blue date code stamps of "9.91" or later.

2) These complaints cannot be corrected by replacement of the instrument cluster; therefore, warranty will not cover instrument cluster replacement for these reasons.

Warranty Information:
Parts and labor for replacing the left-hand side fuel lever sender are reimbursable under the BMW New Car Limited Warranty of 4 Years/50,000 Miles.
