cool a1ek, smart and cheap repair. when I was talking about the carbon layer I meant thr resistor layer on my pcb inside the diverter.it is a carbon layer like a potmeter. traveling distance of the contact copper gives a certain resistance to the ecu to decide position.
I had intermittent fault on my c200. disassembled the valve elec. 5 litle copper fingers sliding on it and scraped off the electrocarbon layer causing the trouble. bought some acrylic based electrocarbon paint.fillrd the holes and tadam works fine
Hi, I have a C3 and tried to diagnose a CLK55 AMG, came back with a communication error to the ECU.I have tried it with a simple OBD reader that was ok.Tried the C3 on my C200 it was fine ,also working on another C200.Any ideas?
