Supersedes Technical Service Bulletin Group 55 number 12-24 dated August 7, 2012 for reasons listed.
Vehicle Information
Condition
"Low Oil Level" message is on in the DIS or MMI.
Technical Background
The hood must be open for at least 30 seconds for a reset of this message to be performed. The message is not reset in the DIS/MMI because the
hood has not been recognized as being opened due to an inoperative hood contact switch.
Production Solution
Improved hood contact switches have been put into current production vehicles, and a software change with improved logic is planned for
production.
Service
Check hood contact switch: Use the VAS diagnostic tester to read MVB 26 in the J393 - Comfort System Control Module (address code 46) after
the hood is opened and closed.
If the value does not change, then replace only the contact switch. Follow the applicable work instructions listed in ElsaWeb for replacing the
hood contact switch.
Tip:
Do not replace the complete hood latch assembly. Replace only the micro-switch.
740
There are two suppliers for B8 hood latches. Check the part number on the current contact switch connector to determine which part number must be
ordered: 8T0953236B or 8K0953236A (Figure 1).
The two suppliers use different designs for the contact switch (Figure 2). Therefore, the mounting location is slightly different on the different hood
latches (Figure 3). The contact switches are not cross-compatible between the different latches. However, the latches can be swapped between
vehicles as long as the correct contact switch is installed.
^ If the value in the MVB changes as expected (normal operation of the contact switch), then the vehicle may have an oil level issue. Please check
the oil according to the instructions in the Repair Manual.
