BMW 118D E87 - Clanging Noise

[PopeyeR]

Greetings everyone, I have frequently posted about my E87, which has developed a sound when I rapidly release the clutch, causing the car to jolt forward, or when I accelerate and then release the pedal in the first two gears, producing a clang sound, akin to something striking the vehicle. There is no loss of performance, and I have attempted various remedies to resolve the issue.

My technician has suggested that the issue may be the mass flywheel; nevertheless, it has persisted for many months, producing a sound akin to metal striking metal.
I was informed that it may be a heat shield around the exhaust; however, it has been tightened, and the issue persists.

The vehicle produces the noise only when the torque engages and there is a quick acceleration of any kind.

The sound seems to emanate from the back right section of the vehicle, or even from the center.

I want to get it mapped, but this is deterring me. It is a BMW E87 118D from 2009, with 26,000 miles and a complete service history.

I suspect the dual-mass flywheel has failed, but I will await more responses.

However, it would undoubtedly impact performance or provide some type of indication, would it not?

I lack mechanical expertise, although I would anticipate it to be an essential element that would display more symptoms.

I agree with Bitxx it really resembles the DMF.

There is nothing else there that might produce that sound while being operational.
