The car, as in the topic, displays the above error and the description 'engine brake failure'. The second error is EDC 03063 and AGR 3004. Where and what to look for, I am asking for a precise interpretation and possibly tips.
FFR 00647-10 fan clutch, simply blocked the radiator fan visco, broke the cable from the electromagnetic clutch and the repair consists only in replacing the visco with new ones, provided that it did not damage the FFR cassette.
AGR 03004 indicates a problem with the AGR throttle or the throttle actuator itself
That's something. Is it possible to measure, for example, the resistance of this clutch, i.e. should it have a specific value? So what does this unfinished boot mean?
The exhaust gas recirculation valve has been replaced and it is ok. Only the visco is left, but you have to see what the price of this miracle is. As far as the resistance of this valve is concerned, it is so much. On diagnostics it indicated a break in the line.
The discussion revolves around the MAN TGA truck experiencing engine brake failure, indicated by error codes FFR 00647-10, EDC 03063, and AGR 3004. FFR 00647-10 is identified as a compressor fault related to the fan clutch, which may be blocked or have a broken cable. EDC 03063 refers to an incomplete boot, while AGR 3004 indicates a defective exhaust gas recirculation (EGR) valve. Users suggest measuring the resistance of the fan clutch, with a proper range of 1.2-1.5 ohms, and note that a reading of 148k ohms indicates the need for replacement. The EGR valve has been replaced successfully, but the fan clutch remains to be addressed, with concerns about potential wiring issues causing short circuits. Summary generated by the language model.
