Pull the cover off the dash in front of the passenger seat. In the freightliner I drove (I don't remember the year: sorry.) I found the flasher in there.
Attached to the brake pedal.
Need to know WHICH Mercedes engine, as there've been a couple. On an M2, you probably have either the 6.4 or the 7.2 engine.
If it was ordered with it, yes.
Need to know the transmission model in order to answer this.
The flasher is located in the center panel behind the shifter. Slide the panel off and it will be the 2nd big square fuse from the bottom left
If it's OEM installed, it should be directly under the door on the driver's side.
Disconnect the battery, keep it disconnected for five to 20 minutes, reconnect the battery.
Code 128 whats is that for. Would it be egr
It will be up under the dash above the pedals OR on the passenger side up in the dash.
If it has one, it'll attach to the engine at the bottom of the oil pan, and, on some engines, the right side of the block.
Bad fuse, bad relay, bad switch, bad wiring... take your pick.
