Driving in Clogs: brake & accelerator does not a fault m
Experienced (or just smarter) hands will undoubtedly know this already, but being very new to the car and the forum I thought I'd post my recent experience of LRA and my muppet antics.
Whilst taking in some hills in N Wales last week, I elected to drive in my walking boots. On several occasions my D3 intermittently lost power and flashed a 'engine system fault' on the display. After the 5th occurrence, convinced I had a fuel problem and the day before I was about to head South overnight, I called LRA. They kindly sent a gentlemen out to see me (who waited by a lake in the middle of nowhere for 90 mins after a few mixed messages whilst I sped back from our walk). He diagnosed eventually that I'd been clipping the brake pedal and accelerator at the same time. He matched the number of occurrences to the times the car had faltered. Upshot: he wasted 2 hours of his day and I learnt that if you depress the brake and accelerator at the same time, the fuel supply is cut and an 'engine system fault' flashes up.
Said gentlemen also told me I needed to have 2 recalls sorted (fuel and brakes, although there was no oil in my vacuum line); that unplugging the battery doesn't clear faults (it takes 40 turns on/off of the key with no other occurrence before the fault is cleared from the system, apparently) and that my coolant was low.
Marvelous. What a nice man, though.PAGODA

40 is b***x - only takes three - thats what I was told AND used a good few times when I first got my first one (was three years ago so might be 4 or 5 but definitely not 40 )
you wanna try driving barefoot - aircon froze my toes off driving through France/Spain in the summer whenever I was not on Cruise Steve N | 21MY Defender | 08MY Discovery 3 (history) | 06MY Discovery 3 (ancient history)

So when ice driving in Sweden in a "fleet" car that may or may not have been hired, we had to remove the ABS and Traction Control fuse and also disconnect the brake light switch as this told the ECU to cut the engine if brake and accelerator were applied together. All that to get some left-foot braking in. Modern cars are far too clever for their own good.Andrew

Andrew,
Yes, the LRA guy said that too. One of the first checks he did was to see if the lights were OK. He also asked if I practiced left foot braking.PAGODA

Given the size of pedals in these cars, what size feet have you got?! I've driven a (manual) D1 in plastic winter mountaineering boots (a bit like ski boots, only bigger clumsier ...) with no problems!

Now that is interesting and could explain a few things.

As I have a manual g'box, I "heel & toe" to start off on hills. No problems.
Perhaps it is speed-related also.

That would be size 14.
Maybe your pedals are different to mine, but the accelerator and brake pedal are pretty damn close to each other and I can see how the brake is easily clipped when driving in clod-hopping boots.PAGODA

I think you're right - at rest it's OK; you'd probably find at speed it cuts the power. I must admit I've not tried it in the Disco, even to counteract understeer at roundabouts Andrew

That would be f*****g enormous then - you can hardly blame the car when you have dinner plates for feet

Presume this is a manual-only problem...
I regularly drive in mountain-walking boots (only size 9 though ) without a problem (and bare-foot, illegal though that apparently is in the UK ) and have occasionally held the D3 back on left-foot-brake whilst applying throttle to ensure a rapid hesitation-free start (in the pre TorqTune days ). Would have looked right silly if that had caused "reduced power"...2006 D3 finally swapped for a 2016 D4 Graphite in Graphite grey. No mods

United Kingdom
Shoe size in the United Kingdom (English size) is based on the length of the last, measured in barleycorn (approx 1/3 inch) starting from the smallest practical size, which is size zero. It is not formally standardised.
A child's size zero is equivalent to a hand (4 in, 12 barleycorns or 10.16 cm), and the sizes go up to size 13½ (8½ in or 21.59 cm). Thus, the calculation for a child shoe size in the UK is:
child shoe size = 3 x last length in inches - 12
An adult size one is then the next size up (8⅔ in or 22.01 cm) and each size up continues the progression in barleycorns.[3] The calculation for an adult shoe size in the UK is thus:
adult shoe size = 3 x last length in inches - 25

The 'left-foot-braking' issue was resolved with a software update to the ECM in December 2006, it affected both manual and auto boxed D3's & RRS's
VIN range 5A300394-5A413980 & 7A413982-7A426404
This can also be triggered by a faulty brake pedal switch
