Renault EDC (Efficient Dual Clutch): DC4/EDC6 de Getrag and EDC7Urgency: Garage soon

Clutch slipping in the EDC gearbox: causes

In the EDC gearbox, 1 documented fault may be the cause: premature dry clutch wear and low-speed judder (EDC6/DC4).[1]

What to do now

Garage soon

Avoid hard acceleration and ask for a clutch quote. If the gearbox is manual, ask about the dual-mass flywheel as well.

What it means

The engine revs up but the car does not accelerate in proportion, especially in higher gears or going uphill. It indicates a worn clutch or one contaminated with oil.

  1. Source for the symptom[1]

Other common causes: slipping clutch

Besides the documented faults of the EDC, these are the most common causes on any car according to the sources.

  • Worn clutch disc[2][3][4]Common
  • Driving habits and heavy loads[2][4][5]Common
  • Damaged flywheel or dual-mass flywheel[3][4][5][6]Possible
  • Actuation faults (hydraulic or cable)[3][5]Uncommon
  • Deteriorated pressure plate[3][5]Uncommon

What to check first

  1. Note when it slips: in a high gear under hard acceleration, on a hill or with a load, and whether there is a burning smell or the pedal is stiffer or the bite point higher.[2][3][5]
  2. Check the fluid level and condition if the pedal is soft or stops halfway: RACE cites the slave cylinder seal as a cause and warns that the fluid is shared with the brakes.[3]
  3. Ask a garage for a diagnosis without dismantling anything, as Motor16 suggests, and have them check the condition of the flywheel when the gearbox is removed.[4][5]
  4. Ask for a detailed quote that separates the kit, dual-mass flywheel or engine work, labour and warranty; RACE reminds readers that the dual-mass flywheel is only replaced if it is damaged or out of specification.[4][6]
