Auto Stop/Start Gear Box Problem

Having stopped and the auto stop start system worked fine, but when pushed accelerator to move forward, Found the display showing alternate D/P but also the auto gear selector knob had lowered and P was showing, engine now running but unable to move forward, had to manually hit start button to turn off engine and then again to restart, thus resetting system and the selector knob raised up to allow D to be set. Has anyone else had this problem as the dealer says he can't see any reported fault codes or a previous mention to land rover of this problem.

probably just a one off situation where the system got confused ... mine did some strange things when the engine stalled after an auto stop start ... i always turn it off now

So glad I found this post, I thought I was the only one suffering this problem.
I have a 2016 Disco Sport and I'm experiencing almost the exact same problem as you except when I put my foot on the accelerator the gear selector retracts into the car and the engine completely shuts down. This has been going on since I bought it in June this year! Land rover have had my car on 4 occasions now and still can't find the fault, no error codes are being found.
Does anyone know of a solution or tip to look out for because at the moment all parties are at a loss!

Mine did this if I moved the selector to N whilst stationary and before start/stop kicked in (no real need to do it just force of habit from driving auto's for years). As I turned it back to D the car didn't re-start, the dash lights went off and the selector dropped and went into P. Restarted manually via the button but confused the hell out of me.

Mine played up today for the first time.

Having started the engine and selected drive it wouldn't move engine responsive to accelerator but the car failed to move. The gear selector just sat there flashing., never seen that before. Moving selector to sport, park, neutral and then back to drive had no effect.

Shutting the engine down and restarting cured the problem. Hopefully a one-off.

Has happen twice to me. First time was on a hill and the car started to roll back before I saw everything flashing, complained and no error codes. Next time I moved the selector into all positions and when it hit park the selector retracted, engine off and park brake automatically applied. Sat there in heavy traffic wondering what to do as it was unsafe to exit. Suddenly after about 30 seconds the car started with no input from me and the selector rose up and I was able to drive away. No error code generated.

Dealer did several check and after 2 days said they replicated the problem saying it was because I removed my seat belt yeah right! :roll: but declined offer to go on a drive because the mech had gone home.

But despite finding nothing wrong, the car now shifts so smoothly you can not detect it unless you look at the tach, the drive-ability is now 200% better. I think in checking the car out a electrical connection may have been loose and plugged in properly. So drive with the old fingers crossed.

Nice to hear your problems have stopped, maybe it was just loose wires? I picked my car up yesterday after the garage found no fault, fingers crossed.
During my problems I've driven a wide range of the loan vehicles ranging from a brand new range rover to a jaguar xe and I can certainly say that since getting my Disco Sport back yesterday it feels like the best of the bunch!

There is certainly some link to the seat belt connector as if I park up at home place in 'P' and stop/start activates then unplug my seatbelt the car shuts down.

I have had this happen twice, both in heavy traffic situations.

In my case, I lose forward drive even though the drive selector is in the D position. The selector is rock solid and cannot be rotated. To clear, I have to press Stop which automatically puts it into Park, and then restart.

Unfortunately now reluctantly jumping ship and have rejected the DS due to the B pillar rattle issue. Great shame, love the car but can't put up with the build quality issues and intermittent faults.

Not sure I want to say for fear of being told I am jumping from the frying pan into the fire :eek: :lol:

I know I could have forced the issue and forced a refund but with a helpful dealer, a very helpful JLR customer services lady and a desire to buy a UK made vehicle, I've gone for a Jaguar F-pace :eek:

Keeping everything crossed for a good one :mrgreen:

In my case I could move to all the positions, but after the car restarted and the selector popped up I could not move it for a long 10 seconds.

Car has no rattles and seems rock solid. Doors close better than any car I have owned with a satisfying clunk! Overall build quality of the body and mechanical parts seems superior as is ride quality especially for a 4X4

I scared the cr*p out of myself last night when the car went into some form of neutral when I was turning right at a busy junction. I think the auto stop kicked in, and when I put my foot down hard on the accelerator the car started and revved without going into gear. I pressed stop button twice and eventually it started again and I could put it into S mode. Caused a jam behind me and looked like I had stalled the car so was rather embarrassing. First time this has happened. I had music on and didn't realise the engine had auto-stopped. I'm going to switch auto-stop off every time I'm in the car from now on, unless I'm in a long traffic jam.

Thanks Barnsh, wasn't aware of this background. I think my neutral problem was caused when trying to accelerate very quickly from auto-stop, which I wouldn't normally do, but indicates a slow response from gearbox.
 
#18 ·
I haven't had this problem (yet) but I have found that the response when trying to accelerate quickly from rest is slower than I'd like. Waiting to turn right today, oncoming driver flashed his lights, put foot down for a quick turn and there's this heart-stopping split second as the car starts, the gearbox thinks, and THEN you move. I'm going to try to remember to turn the thing off for normal driving. It's also annoying that the start-stop only works with the brake pedal. Put the handbrake on, foot off pedal (to avoid blinding driver behind) and the engine starts up again.
Seems to me it's a compromise for the auto - drove a manual loan car yesterday and the system is much more sensible - engine stops when foot off clutch, restarts when you put the car in gear.

Have to agree Past Master .... we have never had a problem with our manual gear-box. The AutoStop/Start is always on ....

Some-times it doesn't work ..... but that is down to temperature and what functions are running .....

When AutoStop activates with brake pedal the brake lights turn off in mine. A good feature.

Not sure if the brake light goes out when in Stop/ Start situation as above, but probably will not investigate as I never use s/s/.

SURELY! (in my opinion) To repeatedly restart an engine without any existing oil pressure is not a good thing, and even worse when the oil will be 21000 miles old! It also then needs a second or so to spin up and begin the turbo pressure before giving power so to expect instant acceleration is a bit unrealistic and not really the fault of the gearbox .
Stop start was "Invented" to get better figures in the laboratory conditions that are used to give "comparative figures" and are not remotely accurate
as the recent V.W. revelations have shown. Any consideration to the long term effect on turbos and engine etc, were not relevant, so as the person who would be eventually paying for the worn components (unless L.R. and all others give a lifetime guarantee) I will continue to allow my engine to tickover
with oil pressure in readyness.

At a quick glance, (that"s all it deserves) I saw that "tickover" is included in the tests!

As there probably is" nothing in the rules" to prevent the use of Stop/ Start at the tickover stage provided that it was automatically initiated, that was the basis on which it was "invented", and therefore used within the test cycle at the" tickover stage." VW and others got up to multiple tricks, are we to assume that everyone else is squeeky clean. ok , one manufacturer did it first and they are all doing it now!

Do you really believe that All the manufacturers went to the expense and complication to add this to their cars if it in no way was allowed to improve economy and emissions figures for the test? and that they turn it off during testing? but fit it simply for the after test times. Also why it is not a delete option and initiates each and every time we start the car. Presumably if we could delete it then it would not be allowed.
Remember:
It requires a better Battery,more durable Starter motor (hopefully) and all the electrical complication to also monitor temperature, gear position, brake/clutch A/C etc, granted some of this is already in the system, but all for no gain, just out of their concern for the planet.

Please excuse my traditional term. Must be my age (and experience) by "tickover" of course I mean "idling"
 
#26 ·
I am fully aware of what tickover / idleing means, and also fully understand Stop/Start.

As I stated , Do you REALLY believe that having fitted this at great expense the manufacturers would turn it OFF when their vehicles were undergoing these tests.? and if instructed to do so I am sure they would be very active in their arguments. What is the point of fitting stop/start if it cannot be seen to improve the consumption and emission results, albeit if only under laboratory conditions.

Non of which has any bearing on my main point that whether used in the tests or not, it has little if any advantage in real time driving, probably contributes to lack of "instant Performance" and submits many of the cars components to undue wear, which in time the owner will be paying for.
