307 2007 2lt HDi Manual. 220,000km Clutch depression.

[lockwood116]

Hi all. The 307 has developed a rattle. It is associated with the clutch. In neutral, clutch out, nothing. Depress clutch in about 1/2 way and rattles in neutral and also if in gear. Gets quieter when fully depressed. I have had thrust bearings fail in other cars and does not sound like it. Any logical suggestions please and no depression jokes.

Dual mass flywheel?

[lockwood116]

Thanks Speaksgeek for the DMF suggestion. But what is the likely scenario?

Thanks, Lockwood116

Not sure. In fact I don't even know if your 307 has one.

It occurs to me that if a DMF was failing, then it might rattle when the clutch pressure was taken off, but perform fairly ok when clamped up most of the time.

I'll go out on a limb and say all Australian 307s with a 1.6 or 2.0 HDi will have a DMF from the factory.

A used one may have had it replaced with a solid one (they are much cheaper).

Do a search here (and on Google) for dual mass flywheel symptoms. It's not uncommon.

I tend to think it will probably be a dual mass flywheel on the way out.

Wondering how far back in Peugeot models the DMF was fitted?

My son has a manual T5 2004 wagon (ie early, low power, 2 litre motor). He had a clutch problem earlier this year - Scullin service centre assumed DMF, but soon realised it didn't have one .

However your 2007 307 is a T6... SLC206 might be right if he had said "all Australian T6 307s with a 1.6 or 2.0 HDi will have a DMF from the factory."

My 2000 D9 406 hdi had a dual mass flywheel.

Purely on the basis that the 406 HDi (at least later model ones) came with the usual NVH items, such as a DMF and clutched alternator pulleys, I went out on a limb with my statement on 307s

I find it highly unusual that they would revert to a solid flywheel, even for the 90hp 307 donk, but there you have it. Perhaps the "low spec" nature of the original HDi (XS trim) meant that it didn't receive the same vibration treatment of the late-model 406?

I can't find any reference to it in the original Peugeot Australia 2001 Press Release, but the Touring Press Release (from 2003) with the same XS spec and 90hp (66kW) motor mentions it:

The DW10 ATED unit equipped with a Bosch injection system and electro-hydraulic control head uses pressures of 300-1,350 bar. This engine also differs from the other version in having an air-to-air heat exchanger and a turbocharger with a controlled discharge valve that enhances both low-speed responsiveness as well as top-end power. A double-damping flywheel smoothes low-speed vibrations.

Perhaps the introduction of the intercooler on the model is the key.

Actually I should check with my son - just because his problem wasn't caused by a DMF doesn't mean he doesn't have one . Although it would appear to be a bit unusual for the car to have exceeded 200,000 km without a DMF problem??

Our 2004 307 T5 HDi only had a single mass flywheel. I would suggest DMF from T6 on.

[Armidillo]

Thanks Hugh - confirms my understanding.

Well not quite. It's not the model, but the engine.

As per press release, DMF appeared in the 2003 (Jan 2004 here) Touring.

As for the rest, introduction of the DMF would appear to have been with the introduction of the DPF (particulate filter) range in May 2005 - which was prior to the T6 model being released (but only by a few months). Apparently local introduction of low-sulphur diesel was the catalyst (pardon the pun).

The DPF appeared when the HDi engines went to a 1.6 with 80kW and a 2.0 with 100kW.
