7G-DCT (724.0): mechatronics and wet clutch

expensive

The 7 speed dual clutch of the transverse MFA platform (7G-DCT / 724.0: A/B/CLA/GLA/GLB) started its early years with jerking and firmware faults; today most of the complaints trace back to the mechatronics unit (valve body and solenoids) and the electric oil pump.

Show the rest

Driven with a faulty mechatronics unit, the wet dual clutch wears faster. The mechanical part (synchros, differential bearing) tends to appear at high mileage.

This is not the longitudinal 7G-Tronic (722.9): a different casing and a different fault pattern.

between 80,000 and 180,000 km

What to check

  • In town, crawling in traffic, watch for jerking between 1 to 2 and 2 to 3
  • Pulling away uphill or in a queue: a delayed clutch engagement is suspect
  • Ask for a fault code read on the DCT controller

Information, not an expert opinion

We write the descriptions, and we put the source next to them. A person reviews them before they go out. They are still information, not a technical expert opinion.

  • A fault on the list does not mean the car you are looking at has it.
  • A fault missing from the list does not mean the model is fault-free. Write-ups are made model by model. Not all of them are done.
  • You decide whether to buy. This is no substitute for an inspection. That needs a workshop and a history check.
