Do automatic cars have a dual mass flywheel?

A torque converter automatic transmission does not normally need a dual mass flywheel because the torque converter does the job, but a DSG is a twin shaft twin clutch preselector automatic and does need a DMF to protect the transmission from too much sudden torque transfer. The hesitation is not due to ‘turbo lag’.

Can a dual mass flywheel be repaired?

The Dual-Mass Flywheel Reconditioning Process Any workshop that it’s worth it weight, will be able to offer you DMF repair or reconditioning as a service option.

What are the symptoms of dual mass flywheel failure?

Somewhat ironically, and despite the fact that the primary purpose of dual mass flywheels is to reduce engine vibrations, excessive vibration that may or may not be accompanied by “clunking”, “thudding”, or other mechanical noises is usually the first symptom of a failed or failing dual mass flywheel.

Why do dual mass flywheels fail?

There are many reasons why a dual mass flywheel can fail. The main reasons are: Heat – Excessive heat is a big cause of most dual mass flywheel failures. A slipping clutch generates heat; if your clutch is worn, you can still save the flywheel if you get the clutch replaced early enough.

How long does dual mass flywheel last?

We asked AA technical specialist Vanessa Guyll to explain the issue. She told us: “David’s Vectra uses a complex dual-mass flywheel. These smooth out the vibrations from modern, powerful diesel engines. They’re not as reliable as solid flywheels, but should last at least four to five years.”

Are dual mass flywheels any good?

Dual mass wheels also improve fuel efficiency by allowing for more effective and efficient use of engine power. Dual mass flywheels are tuned to match the engine torque curve, vibration characteristics, and vehicle load conditions – failure to keep to these parameters could result in premature damage to the flywheel.
