Actually not seen that before.
What conditions have to exist to stall the engine then? I'll admit to having done it a couple of times. |

Interesting that they did it on a gravelled surface so the wheels could spin relatively easily. What would have happened on tarmac or a similar grippy surface? Would the system give up under an overload command or continue until something went bang? |

Was anti-stall around for the 07MY? I'm sure the chap on the LR driving experience I went on said it was introduced at the same time as the move to 2.2 Puma. I guess he could have been wrong.

I wouldn't believe a word those LRE folk say 😉
Seriously though, anti-stall was avalible on TD5, but a more basic system. All Puma's have anti stall. |

Td5 did have anti stall but in 07 it got better.
To be fair to the system it's in low box and puma engined defenders are fantastic in low box. It just keeps the wheels moving with no throttle input. I went to the launch at eastner probably one of the best days I've ever had. Being free it was cheaper than getting married. |

If it was available on TD5, how can I tell it its fitted on mine, or is it standard? I've never stalled it before, but I've only had it for a few months.

As above, all Pumas have anti-stall.
A better test is to put it in 1st low, crawl along with no throttle, and gradually apply the brakes. Then a little harder. And then harder still 
I can have 2 feet on the pedal, pushing against the seat/bulkhead, and it just keeps dragging itself along, even on tarmac. A truly impressive system 
In the video above, if it had more traction, I expect it would have stalled, broke something, or just sat there shredding its tyres on the road surface  |

Shred it's tyres or broke a half shaft.

The anti stall is useful. I pull away without using the throttle and then press it once moving. This also works with the caravan on and is a nice smooth technique once mastered. You also then don't need to use the handbrake on hill starts, even with a big van on the back.

My Puma was bought from Matford in 2012 & I was given the usual half day LRE voucher when I picked it up.
I booked a visit to Eastnor & chose a 110 SW for direct comparison with my own. I'm pretty sure it was a '12 plate vehicle, as I think it was the first year that they did away with carpets. The instructor's favourite trick of the day was to demonstrate pulling away on hill starts with the brakes still applied. i.e. Stop half way up a hill, and hold vehicle on the foot brake, while still in gear, with the engine running. Keeping your foot hard on the brake pedal, whilst releasing the clutch pedal, enabled you to pull away with no risk of rolling backwards. Apparently, modifications to the abs system, in combination with the anti-stall & traction control systems, had made that feature possible for the first time. The explanation was that on the old system, the abs sensors on the front axle talked to one another, and sensors on rear axle did the same, but front & rear axles didn't talk to one another. However, on the new system, the sensors talked to one another across both axles, if that makes sense? He told me that this feature was installed from 2011 onwards, but I've no way of knowing for sure. You will have to give it a try to find out for yourself. The brakes groan like hell, but the vehicle will pull away, and will not roll back or stall. Obviously, you should release the foot brake once you are safely on the move. Apologies if this is already common knowledge and I've just wasted several minutes of your life! '57 Defender 110 XS Station Wagon 2.4tdci |
