Thread: Throttle Response

I've had this problem a few times (MY14 D4 SDV6). It seems to be under the following conditions:
- engine cold
- some steering lock applied
- throttle pressed heavily for quick takeoff

The unfortunate problem is it usually happens when you're turn into or across heavy traffic. It hasn't become dangerous yet because I'm aware of it and don't usually press my luck just incase it happens.

Have you tried dropping into 1st or better still, sport mode and 1st? By default it is programmed to take off in 2nd gear and in a more leisurely way.

Also, if you mainly just poke around like an old granny, then the vehicle will adjust to that driving style as the norm which means it takes a bit to wake it up when needed. Try a bit of spirited driving from time to time to sharpen things up(hard acceleration with high revs).

I don't tend to poke around. I like a little bit of right boot

I had the same issue when I had the TDi Territory before this and was able to be completely rid of the problem once I had the ecu tuned.

I have tried driving in sport mode today and it does seem to sharpen the throttle response but I wasn't in any situations where I expected I might have the issue.

Peterall-
I overcame all those issues mentioned by getting a remap done on my MY2011 RRS 3.0lt STDV6, by Superchips.
ECU Remap | Chipping | Engine Tune | Peter James Tuning | Superchips.
This does require the ECU to be removed from the car so the parameters can be adjusted.
241 bhp to 274 bhp (204 kW)
600 Nm to 697 Nm
The remap can be programmed to suit your requirements.
Mine were: 75% city, 15%towing, 10% 4WDriving
Result after 12 months driving has been:
1. Improved towing with 2 tonne van. (reduced fuel consumption 2-3 lt per 100km as you don't need to push the throttle as much)
2. Improved throttle response in town..no turbo lag (consumption down 2 lt per 100km if driven conservatively, goes up when pushed)
3. Much improved torque for heavy 4WDriving
I could not be happier.

how much does a remap cost?
was seriously thinking about getting one of the sprint booster/ wind booster units for my D4MY10?

Wind Booster is nothing but the electronic equivalent of pushing throttle further.
It can't remove lag...

What motor is in your MY10 D4? 2.7, TDV6 3.0 or SDV6 3.0? Prices and process varies depending on what you have. Take a look at Superchips ? petrol and diesel engine tuning, ECU remap software for maximum driving pleasure. and put in your details - note that Peter James is the "local" rep for Bluefin.

I wonder if the hesitation with some of these cases is a dodgy brake pedal switch? You say to car "Go!" - but car thinks you also have foot on the brake and it thinks "No!"

The issue has been reported since the inception of the D3 .... nothing to do with any switch or any hardware, just about every car has it occur from time to time .... and it's not a turbo lag issue either as every single person will report (especially the 600nm twin turbo owners), that power can come on instantly in some cases and needs an email in others ... .


Same car ... as in the actual same car .... can perform completely differently from time to time.


Has to be software. There are a lot of smarts built into the ECU and how it 'talks' to everything .... and I think that's where the flaw lies.

I drive mine like an olde fart.
Dont I love that OH WOW when I push the pedal flat
