V8v 4.3 clutch? Tell tale signs plaese help?
Discussion
After driving my 06 v8v 24k for 1m I have found that the car makes a lurching noise after the clutch has been engaged and the car is driving till the car gets up to higher speed.
This also happens at lower engine speeds while turning sometimes in 2/3rd gear.
Is this normal or should I be budgeting for a new clutch?
The car has just passed a 1yr Aston warranty and there was off clutch wear. The car also has no signs off clutch slip.
Please help

Dave they do have there own quirks, but from what you describe it seems strange, on low speed cornering you can get a vibration, the brakes can cause squealing and vibrations, where are you based as may be able to recommend someone who can road test and give you a comparison over what is expected,
Out of interest, what speed are you doing when you notice it, and what speed does it disappear at.
And without wishing to come across as rude, are you *sure* you're in 2nd gear when it happens?
I think I know the noise you refer to, but it only ever happens on mind when I try and manoeuvre in too high a gear with the revs low. Or occasionally in 2nd or 3rd if I use the "anti stall" trick (just letting the clutch up with no accelerator - a function I'll miss if my next car doesn't have it ).

What's that then? The only anti-stall trick in my DB9 is more throttle. eta - the no throttle thing works, but not uphill.

The car only does it in low speed not always cornering when the engine is in low revs ie when its labouring.
Im Based up in sunny Newcastle was thinking off either aston workshop or stratstone.
On my warranty check from Aston my car passed with flying colours no sign off clutch wear.
The car has also been serviced by Stratstone in July.
Rick I understand bout cars having thei own little quirks I'm in the motor trade I have sold cars for 7yr and a total petrol head to boot.
I just wanted some advice thats all dont want the lads in our workshop to look at it they wouldnt have a clue!!
How much would a new clutch be??

the price of the clutch varies considerably as labour rates vary,and the stated labour time is over 8 hours, independant price for the whole job including clutch, flywheel, spigot bearing and concentric slave cylinder, labour and vat would be around £2200.00 I would check with who you intend to use, but from what you describe i would not think it is the clutch,
If the noise you are describing is a low grumbling when pulling away in low revs, I get this also. Just give it some more throttle and let the clutch out as soon as you can (within reason). Similarly, if you labour the engine in 2nd or 3rd, you get the noise. Basically, I've concluded that these cars don't like being babied when pulling away.

I agree.OP - it really depends what you mean by low speed, labouring etc. But it sounds very much to like a "they all do that sir". Have you tried the clutch test at speed (drop the clutch/bring back up/accelerate in a higher gear)?

I was meaning the lack of need for any throttle eta - the no throttle thing works, but not uphill.
Not tried it up a serious hill as don't recall ever being in traffic (when it's of most use) when on a decent incline...

I think theres some anti-stall throttle control in the software so it applys revs if it thinks its going to stall.....its almost like a bit of creep you get in an auto box....so reversing up hill you dont slip the clutch or give it lots of throttle at all...just let the car do it for you and cover the brake
in conjunction with the fly-off handbrake , and it also makes hill starts much easier ...usually when you see a car with 10K miles on the clock having a new clutch, its because someone hasnt got the hang of this, theyve been holding the car on the clutch on hills and giving it loads of revs/slip to get going

I Completely agree with this, with one addition don't rest your foot on the clutch pedal when cruising, bogie said:

You learn something every day !
This noise is simply the 4 springs in the centre of the clutch plate vibrating as the engine revs fall too low under load. 99% of RWD road cars have a rubber "donut" in the propshaft to eliminate any transmission vibration/noise into the cabin. The Astons are a sports car, and don't have the "donut".
