Does the clutch/flywheel vibrate on the 2.0 Hdi 3008's

In relation to my original post;
Peugeot 3008 2.0 Hdi 150 Clutch Judder & Fuel Consumption

Last week I saw a 2011 plate 3008 exclusive with just 7.5k on the clock at a local Peugeot dealer and went to have a look. I was interested to know if the clutch had some judder at the bite point, like on my own 3008. I was expecting it to be a totally smooth pickup as the clutch was lifted without depressing the accelerator much - just like on the 1.6 hdi I had test driven some months ago. I was quite amazed to discover that it JUDDERED! - just like on my own, although not as severely!

So what is going on, is this really how these 2.0Hdi's left the factory?? or is this another lemon with a worn/damaged clutch or flywheel??

Look forward to any feedback on this.

I have a 2.0 Hdi Exclusive, from new in May 2010. Now got over 20K on the clock. Never experienced any judder whatsoever.

Hmmmmm, thanks for that jet_andy, perhaps I need to seek out a few more 3008 2.0 Hdi's before coming to a firm conclusion. Would love to hear from anyone else who has driven the same model of car. Is it a total coincidence that my car and the other from the same dealer have juddering on the clutches?

My car has had two previous owners according to the V5, it is a late 2009 model and has just 10k on the clock. Am I in a position to insist upon the replacement of the whole clutch/flywheel assembly? I have been told by one dealer that as I am not the first owner then I may have to sign a declaration before the problem is investigated and if nothing is found I would then have to cover all costs. Is this true

btw jet_andy, is your car absolutely vibration free when no revs whosoever are applied and you just allow your car to creep forward a bit, no pulsing through the clutch pedal etc. Also, what mpg do you average all in all and at what average speed is that measured at? Thanks v much for your input, much appreciated.

No vibration whatsover - would never have even thought about it had you not said. I can creep in slow traffic, pull away gently or quickly, whatever conditons. My wife drives it as well, and never had any bother - in fact she loves it becasue it's so smooth.

As far as mpg goes - my commute isn't particularly economical, about half is thorough back roads, using low gears, more akin to a city. I also don't tend to hang about - I like ot get a move on. Even so I average about 42mpg, but if I do a long run somewhere that goes up to high 40's, even with my heavy foot.

Thanks again for that extra info jet_andy

Can I ask at what average speed does the trip computer report that your typical 42mpg is achieved. Would it be around 30mph for that kind of economy or a bit less?

It looks like judder isn't the norm then, no one else has posted on this thread saying that they have had similar experiences to my own.

Since diesel cars have so much torque it seems to me quite usual to let the car inch forward a bit on the clutch without the need to apply any throttle, particularly when stuck in traffic. If that clutch action is totally smooth on your car then it seems there is a problem somewhere on these other 3008's.

Do you know if your car has the lastest ecu software. My car has according to the main pug dealer be upgraded and it did reduce the severity of the judder considerably but I am yet to determine how the altered software can actually achieve this, would love to hear an explaination or even a bit of a possible theory.

[jet_andy]

Yes, about 30mph.

I think it has a SW update about 6 months ago when it went in for a minor job.

My 407 2.0HDI has a slight judder if you bring the clutch up and don't put any revs on at the same time, and it has had a new clutch and dual mass flywheel. I would expect any car to respond in the same manner. It will tick along with no revs, i.e. in slow traffic, but at the initial bite you are bound to feel something. To me, if you don't, I would have thought the clutch was on its way out!

[Alex878]

Thanks jmkent. That gives me some reassurance on the clutch/flywheel issue.

After sending the car back to the dealer for some diagnostics they reported nothing amiss apart from a few low tyre pressures which I suppose could have been robbing a couple of mpg. It is on the latest software version and they confirmed that it has just had the one upgrade since manufacture. I wonder if these software updates throw out the mpg readings on the trip computer - I will have to do a proper test by brimming it and doing the calculation. I read somewhere that remaps cause errors in the fuel metering system and so can't be relied upon too much.

[Alex878]

jmkent, forgot to ask, did your 407 have any judder well before the old clutch & flywheel got to the end of it's life. Sometimes judder can result from misalignment of the clutch & flywheel assemblies I understand. There are a hand full of reasons but am trying to get to the bottom of whether it really is a so called characteristic of some of these Peugeots. I suppose I will need to check out a few more 3008's if possible.

[jmkent]

Yes it did, used to make a noticeable knocking sound, and could feel a definite vibration. There was a definite rattle to the flywheel.... sounded like a bag of bolts when on tickover, and shuddered with a rattle when switching off. None of that now though.... switch off, and it just stops

I do believe you will get some judder though with these torquey diesels.... that initial bite point is starting to transmit a reasonable amount of torque/drive.... in my mind, if it didn't bite and judder slightly, and instead went smooth without any feeling, that to me would say the clutch is wearing and not biting properly. I am no mechanic, but it seems logical to me

p.s. I've driven dozens of different diesel cars over the last few months, and the way my 407 drives doesn't stand out as being the odd one out of the bunch in the way it performs like this..... and that includes Ford, Vauxhall, Kia, Renault & VW and all of which are <6 months old with <10k miles
