I have been struggling for 2 years now with 400e 1992
Abs light comes on when i exceed 50kmh,
sometimes very quickly sometimes after some minutes.
Cruise wont work also.
My car is non Asr version.
Home made blink code reader gives from pin 6 (abs)
16 flashes (Vehicle speed sensors (L6, L6/1, L6/2), implausible signal)
I have changed ALL abs sensors one by one to new oem.
Before i changed front right sensor, i got sometimes also 3 flashes (front right abs sensor) from the Pin 6.
List of what ive done so far:
- All new abs sensors(3)
-New brake light switch
-Changed Abs pump relays (used parts)
-Changed Abs module (used)
-Measured abs wires from the sensors connectors
to the abs module with multimeter that the wire are okay
-Checked abs pump electric motor, okay
-Something that i cant even remember
Still nothing has chainged.
I have changed my rear diff from original 2.24 to w140
3.5td 2.82 and changed the abs ring from the old
Pinion, due to info that ive found on here.
But the issue was before this diff change.
Could be that both off my Abs modules are bad?
Only thing left that i can figure out is that i measure
Abs module capacitors if theyre gone bad and if so
Change them. (Ive fixed this cars T/LLR and LH by changing those dead capacitors).
