Reply With QuoteMy Nov 09 3.0 doesn't instantly get moving straight after stopping so it might have the same malady. I notice it every time I stop at the local railway crossing where the stop is almost always just to comply with the sign.

SupporterOn Wednesday, I decided to get Barbagallo to replace a chafed hose that they had ordered for me so I decided to drive the D4 TD3 SE to work instead of my BMW motorbike.
After 5 minutes in stop start traffic the car decided to have a second or more delay between pressing the accelerator and deciding to move. Once into the inner suburbs the delay increased and then, when pressing the accelerator and trying to go with nothing happening, every error message under the sun flashed onto the screen. Rolled to a stop, restarted the engine and then everything was OK until the next traffic lights when the same thing happened.
I managed to get the car to BB after about 10 kms of delayed throttle, but no more error messages. To their credit they looked at it straight away and after one false diagnosis and getting the car back to them on a truck after I left to try it out, they replaced the brake light switch. So far, the car is running perfectly with the new switch, so it looks like the problem is solved.
Looking back, there has been a slight delay when accelerating from a stop over several months. It felt like turbo lag but it has now disappeared and the response is instant. This lag is probably an early sign of the stop switch failing so something to be aware of. My car was first registered in Jan 2010 and has done 70,000 km. It just had a major service 2 weeks ago.
My wife usually drives the car and she did not notice anything. However, now she tells me that the car takes off straight away instead of feeling like it doesn't want to move like it did before. It was a very subtle change until the almost total failure, which came on very suddenly.
Looks like a good spare part to carry on remote trips! The part is "Switch-assembly Stop", part # ROXKB500110, for future reference.

SupporterGraeme,
Yes, it sounds like the same thing. It is just enough delay for you start to think "I wonder if or when it will go" and then it is off before you can really fully think the thought!

I have the same issue.....mine actually sits in second as I am almost at a halt. Put the foot down and it takes sometimes a scary and dangerous period of time (probably only a second) before it jumps back to first.Originally Posted by Graeme
This happens in the same spot for me each and everyday, so if I drive it in sport approaching this spot and there is no issue. Appears to be poor programming.

I have another thought though. After recent major surgery on the D4 the response was immediate for a while before it returned to having its previous "think" time. Perhaps BobD's gearbox adaptations were reset because that often overcomes the delay so I'll reset mine and see if there's any change.

SupporterFollowing the Transmission fault / HDC fault thread I bought a brake light switch off eBay here:
Land Rover Discovery 3 Brake Light Switch | eBay
Pity it's gone up $10 in the last week!
Easily swapped over, the old one had "Landrover" on it so it was an original switch. Luckily it has lasted 7 yrs!
The new one has "FoMoCo" ( Ford Motor Company) on it.

SupporterI find it amazing that a faulty brake switch can cause suspension faults - the programmers of the software in these vehicles need to take a reality check.
Thankfully in 18 months of ownership and 25,000km I have had few issues but get worried when I hear about such stupidity.

Ditto. This is very interesting. I have a MY11 HSE. I thought is was turbo lag for a split second and then there is a power surge and off you go.
I might get the local dealers to have a look at it, and while there have a drive of a new D4 3.0lt and see if there is any difference.
Regards Trif.

SupporterThe D4 is still running perfectly, several days after replacing the brake switch, so it appears to have been fixed, thank goodness.
Still no delay when accelerating after a long or very short stop, so I am very happy. The only time it takes any time at all to think about which gear to select etc is after coasting slowly and then accelerating. Still nothing like I have been used to over the last couple of months.

I've just reset mine's gbox adaptations so will monitor for any improvement tomorrow.
