AFFECTED VEHICLES
CONDITION
Message in MMI reads: Low Oil Level."
TECHNICAL BACKGROUND
The hood must be open for at least 30 seconds fora 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.
