Ремонт коробки EDC DC4 Renault

For parts selection and purchase Telegram https://t.me/viktorcoral Renault EDC DC4 Gearbox Repair Repair of the mechanical part of the EDC DC4 gearbox (Getrag 6dct250). Repaired in Drohobych (I'll send you contact information if needed). This gearbox is installed on Renault cars with a 1.5 dci engine after 2009. I have a 2011 Renault Grand Scenic 3. It all started with intermittent errors: check auto gearbox, check anti-pollution system, DF 390 (177564), DF 391 (177664), DF 388 (175062), DF 392, DF 381, and others. In most cases, odd gears would disappear, and restarting the engine would resolve the issue (anti-pull disappears after clearing the error; clutch adaptation sometimes helped). Then a noise appeared when shifting from 5th to 6th gear, and then a crunching sound when engaging 3rd gear. The mechanical part of this transmission is considered reliable, and the problems are usually with the electronics. In my case, mechanical problems were the opposite, leading to electronic failures. After speaking with mechanics, I found out that the EDC transmission is a frequent guest for them. The main problem is wear of the differential bearings (especially the left one), which suffer from poor lubrication and wear debris from other components. In other words, the transmission oil is not changed, it loses its lubricating properties, and all mechanisms wear out. An EDC (DC4) transmission oil change is recommended after 50,000-60,000 kilometers.
