Accelerator losing power again!

This problem first came my way in December 2011, when I drove through a large puddle and a couple of minutes later, lost all power on the accelerator. Took to first Land Rover "specialist" and they didn't have a clue as it's a TD5 and they don't like to fiddle with electrics!

Problem happened again four more times, again it seemed to be whenever the road was wet (rain or slushy snow), so took to another Land Rover specialist and they did a diagnostics check. After much fiddling around resetting the diagnostics on the vehicle, the diagnostics check revealed the following info:

"Electrical fault - check the wiring"

Thanks for that. £10k well spent on a diagnostics machine that states the obvious! (The guy told me that's what the machine cost him).

So, the first thing was to replace the wiring loom as it was soaked in oil.

Same problem happened a week later, so back to the same guy and this time, faulty air filter replaced which seemed to do the trick. This was back in March 2012 and the LR has been running fine all year, until hitting the snow a couple of days ago. It was fine for an hour or so, then the accelerator lost all power and I trundled back home at 10mph! Luckily I was only about a mile from home.

So first question: could the air filter have a fault again? A new one was fitted just 10 months ago. Maybe an oil leak into the filter?

Second question: any other suggestions?

Bear in mind I'm not too mechanical - can check the oil and water, but that's about it!

Thanks

Pete

Think the air filter will be due for changing anyway, I replace mine twice a year

Could also be your fuel filter, in tank pump or the playstation pedal

Thanks for the replies.

The pedal was replaced by the first lot who took a look.

Forgot to say that the electrical warning light also comes on when it happens.

The vehicle is kept in a garage most of the time and it is very damp in there (leaky roof). Not sure if this would affect anything long-term?

Thanks, that's a possibility

there is alot to be said for a throttle cable and mechanical fuel pump..

If the warning lights coming on try checking the wiring/connectors around the crank sensor and tps maybe take em apart and give them a spray may have corroded if kept in damp conditions.

Also check ECU relay and fuel pump relay and earths

Was there not some recall on the TD5 for this problem? Something to do with oil leaking into the ECU?

If the check engine light light has come on and you've lost all throttle response then I'd guess it'll be the throttle position sensor (playstation pedal) or it's associated wiring (9 times out of 10 it's the wiring IME).

You need to see what the actual fault code(s) logged on the ECU were when it died, that'll give you a good clue as to where to start.

Is there a code for "electrical fault check loom"?

Not as far as I know, all the reading said was "Electrical fault - check the wiring", but I need to get this latest one checked as it could be a different problem even if the symptoms are the same.

Lol oops!

I've been lurkin' (and laffin') for a while so forgot I never introduced myself.

Been driving my 2000 TD5 defender for about 2 years now and love it. Just about got it all working (there's always summat to do though aint there!). After it spent best part of 8 weeks off the road with an enormous garage bill last year I vowed never to let anybody else under her bonnet again. so I've spent far longer than is healthy poring over the workshop manual and 'leccy drawings. I need to spend more time getting her dirty so that's this years aim/resolution.

Oh and can somone explain to me how to engage ma difflock?
