EDC7 (7-speed, wet clutch, DW5) gearbox: faults and reliability
Renault EDC (Efficient Dual Clutch): DC4/EDC6 de Getrag and EDC7 version
With caution
The specialist press praises its smoothness compared with the EDC6, but it is not free of faults: Renault had to update the calibration of the first Mégane IV GT cars by software because of a gearbox overheating that increased the risk of an accident. Also check the vehicle's history and that there are no stored gearbox warnings.[1][2]
What changes in this version
Second generation, with a wet clutch (internal code DW5) and one more gear, which Renault introduced in 2016 with the Mégane IV and Scénic IV to correct the roughness and low-speed slipping of the original EDC6. Since then it has gradually spread to the more powerful, higher-torque versions of the Clio, Captur, Mégane and Kadjar.[1][3][4]
Engine codes of this version: DW5.
