    D3/RRS Pregnant Pause at Roundabouts

    Plenty has been written about the pregnant pause that occurs when you slow down for lights or roundabouts and then decide to proceed but nothing happens for a second or two and then you are off like a scalded cat.

    Doesn't happen in command shift so not s turbo lag issue - consensus is just a gearbox programming issue.

    I have had to lend my car to a friend for a few days and he does not like driving it around town because of this issue - he claims the problem makes the car too dangerous to drive in roundabouts etc - the pregnant pause for a second or two and if the accelerator has been floored to compensate then explosive acceleration. Now when I first got the car I would have agreed but with 15,000km under my belt I anticipate it and now rarely get caught out in closing traffic with no go.

    My car is a 07MY and I understand there is a software upgrade to alleviate the problem. With the exception of recalls my car has never been to a dealer so has had no software upgrades. Each time I visit the dealer and ask about the costs of software upgrades they do not seem interested and are vague about costs etc - basically normal labour cost for however long it takes.

    So has anyone had their gearbox software updated?? Does it cure the pregnant pause in acceleration and what are the costs??

    Thanks

    I had my 2007 D3 SE updated for this issue last year and it did make a huge difference. The dead spot was still there but occurred far less frequently.

    I see in road tests the new Ford Territory with the 2.7 diesel & 6 speed has the same issue too.

    Yes the software update for the gearbox helps but a Remap truly fixes it!
    You choice which one, I recommend the BAS Remap.

    D4 3.0l has the same problem, though like you, it rarely catches me out anymore, as I must have adjusted my driving style. If a D4 still has the issue I suspect that any software upgrade would not be a complete fix.

    In heavy traffic I sometimes select Sports mode, when approaching roundabouts, etc. I don't even know I'm doing it. Generally I don't worry about it, and rarely have an issue....I must have adapted to the adaptive gear box....LOL!!!

    Cheers,

    Kev.

    So the remap also does the gearcox ecu as well as engine ecu?? the issue being when rolling in to a roundabout and still doing 10-15kph, the gearbox does not seem to change down below third and when you put your food down the box is in too high a gear and hesitates until it changes down a gear - maybe it does this to endure the turbo is always spooled up but as Command Shift shows when you change down manually, even if the engine is off boost there is plenty of power to take off when coasting.

    Thanks to everyone - I might see if I can hold the dealer down for a quote to upgrade the software - am looking at a remap down the track.

    Cheers

    No the Remap does not reflash any CPU but the engine mapping,these are seperate modules of which the vehicles have many. I had 5 modules software updated last week to fix other electrical issues I had.
    My mechanic uses Autologic and would charge $110 for this software update, he explained they have download te existing file off the car and email it to the UK, Autologic emails back the most up to date correct file for your car which they upload.
    I'm sure others who have had a remap will verify the pause you speak of disappears.

    At the risk of being labelled a Luddite, I must say I can't help wondering if this is another example of the boffins thinking it is their job to make cars that are cleverer than their drivers.

    It seems that engineers, in many cases software engineers, come up with some really clever security/ safety/ environmental feature that seems like a good idea on paper, but which fails to consider or fails to realise the importance of some real world situation where the "feature" becomes a nuisance or a liability.

    I am aware of the fact that cars are safer, more reliable and more economical than they used to be, but that doesn't disguise the fact that increasingly we hear of instances where the boffins don't quite get it right. Prius's safety problems, at first blamed on the floor mats, were apparently a software issue. Just ask drivesafe about the problems that can arise from electrical failures in a lot of modern vehicles or read his "Most dangerous 4x4" thread.

    I have the D4 3.0Lt and the only time this happens to me is when I start it first thing in the morning and go to pull away from an intersection, otherwise, all good.

    Rich, Thanks for your post info. My related issue is during higher speed highway overtaking at midway point we lose power/speed for a frightening period and with great concern and embarrassment have to retire from the manouevre. Dealers cannot reproduce this situation at test drive . Do you think your Auto Logic consult would be a suitable pursuit. If so, can you nominate your contact?
    Cheers
