Intermittently the drivers side electrics and the soft close function on the drivers side don't work on my 2002/02 S500. I had it put on STAR last week by a specialist and the following faults came up for the drivers control module:
B1521-005-Exterior mirror adjustment and heating. The mirror heater has short circuit or open circuit.
B1521-003-Exterior mirror adjustment and heating. The mirror fold-in and fold out feature has short circuit or open circuit.
The soft close doesn't work at all on the front passenger door.
B1521-003 also appeared on the Front left control module with:
B1193-000- Component S86/2s1 (power locking microswitch) is closed for more than 80s.
These faults were cleared and the specialist told me to bring it back if the problem continued.
Can anyone shed any light on this issue before I take it back to the specialist, so I have some idea what to expect.
By the way the drivers side door wiring was checked for broken/damaged wires but all appeared well.
