SUBJECT:
Fuel Gauge Reads 1/4 when Tank is Full

MODEL:
Z3 (E36/7) produced from September 1,1998 to April 4,1999

Situation:
After filling up with gas, the fuel gauge reads approximately 1/4 full, and then moves very slowly to the full position.

Cause:
Software error in instrument cluster.

**Correction:
Do not replace any components.

Recode the instrument cluster using DIS CD version 18.0. or later (available June 1999) as follows:

Select - Coding/Programming / ZCS Coding / E36 / Recoding / Kombi, and then follow the on-screen prompts to complete the coding process.

Recoding the instrument cluster activates an internal day counter (instrument cluster test function test # 3.1) If test 3.1 contains a value greater than zero, this indicates that the instrument cluster already contains the fix.
Note:
After recoding, test 3.1 will show a value greater than zero on the day following the recoding operation.**

**Warranty Information:
Parts and labor are reimbursable under the terms of the BMW New Car Limited Warranty of 4 years/50,000 miles.
