...has anyone else experienced this?

When cold, the car can judder for a second or two, as if there isn't quite enough power. It doesn't always do it which makes it difficult to show to the garage.

Any ideas?

Had similar problem on mine.
Went to the dealer who had a procedure to reset clutch by inserting key, i think 3 times but not starting car, and all was well.
Give them a call and im sure they will tell you the procedure.

it's really simple and is advised to be done on each cold start up where possible

Preferably with a cold engine, select NEUTRAL to illuminate the engine start
button.
Start the engine and allow it to idle whilst still in NEUTRAL for ten seconds.
You will notice a 'click' from the underside of the vehicle as it does the check,
this is normal.
If the adaption has not been done for a while carry out this procedure 3 times to bring it in line,

I get a similar thing on my DB9 when its cold. Seems like a judder when pulling away and worse if pulling away whilst turning. Always when cold, never does it when hot.

hangingman just try something for me first, next time you try it from cold knock off the traction control before driving off (press and hold traction control button for 10 seconds until warning displayed on the display) then try the car let me know if this helps, secondly have you had the 4th year 40000 mile service yet, you can either get me on here or alternatively pm me,

Not quite the same problem but I have resently taken delivery of a 4.7 V8V with sportshift. On an extended run of c. 250 miles of motorway driving I got a fault come up on the display. "Sportshift paddles disabled only buttons active". Spoke to the garage and they said I should disconnect the battery for 10 mins to re-set the computer. This has not worked and the fault has returned intermittently after a long run in the car. Booked in to be checked but I was wondering if anyone else has had a similar problem with the sportshift. Sounds like a sensor problem?

wink i won't mention 1st and 2nd gear being tight on the V8 manual when cold (without the mod) possible high clutch wear or the selector cables coming detached, Doh!!!

pros and cons to both systems must admit love the manual for pure fun,

Tried it from cold today with the traction control off and it was fine, no judder at all. Last service was the 20000 miles/24 month one.

changingman yours is to do with the traction control and rear brakes,i would recommend a clean up and deglaze of the rear main pads , also making sure the handbrake pads are not over adjusted, if the inner handbrake pad is wearing out faster than the outer this is a good indication of over adjustment, unusually it is better to have a handbrake that comes up a little higher than on most other makes, as you mentioned when they start to warm up the judder goes away, The rear brakes control wheelspin and it is this operation you are feeling and hearing,

Rick, thanks very much for the info, I will pay another visit to HWM. Would you imagine this could be done under the warranty or is it just a wear and tear fault. Whats the significance of my car not yet having had the 4 year service?

speak to jon in service, if it requires just a clean then that does not take long, if the pads are 60% or more worn they advise replacing the pads, at the 2nd 4 year service the rear axle oil should be replaced and the filter cleaned, seem to remember there has been a change in the spec of the oil, would have to check this though to confirm,

Funny thing is that the procedure is mentioned in the owners manual .... I guess not many people bother to read it .... winkbiggrin
