Customer Question
When I 1st buy this...
When I 1st buy this car it was showing the abs and esp on the board and I wanted it to be removed, I took it to a diagnostic machine to clean the fault and after cleaning the fault stayed, so the computer showed speed sensor as a fault, then I ordered the sensor cables. When we changed them the car refused to change gears and remained on gear on and that when I started straggling looking for new cables etc ... and we tried several new cables even from bosh Germany and I changed the gear box oil and the filter. Still it's refusing to change, now the last Mecanician told me that it's may be the Sbc so am confused now

Hi, my name is***** your speedometer is working, the wheel speed sensors will not be the problem with the transmission. The transmission problem will most likely be caused by faulty speed sensors inside the transmission. You will need to get the fault codes from the transmission control unit using a factory level scan tool. More than likely there will be fault codes stored in the transmission control unit that indicate faulty transmission speed sensors.

I will try this tomorrow but we don’t have good mechanical in my country, all of them they just think it this or that.
Customer reply replied 4 months ago
Am not sure if the speed sensor is working or not because it showing to all diagnostics that it is a speed sensor fault
Customer reply replied 4 months ago
What they are saying about the Sbc is it true that can cause that problem
Mercedes Mechanic: Marty, Mercedes Technician replied 4 months ago

Do you have any fault codes that you can post? The SBC will not cause the problem.

I love this car and like I said before, all started when we changed the speed sensor cable because it was showing the ESP and Abs malfunction.But the car was working perfectly
Mercedes Mechanic: Marty, Mercedes Technician replied 4 months ago

How can I send you the code
Customer reply replied 4 months ago
Write them down for you or screen shoot them, any diagnostic machine can get that?
Mercedes Mechanic: Marty, Mercedes Technician replied 4 months ago

A screen shot is best. You need a Mercedes scan tool that is able to read fault codes in all of the modules. I need the codes from the traction control, SBC, engine and transmission modules.
