Accelerator wont work in gear.

Just tried to book it into a well known independent and they said
"I don't think a diagnostic would find that problem, it could be a problem with the ECU".
Silence


"I suppose we could have a look at it on thursday"

I say: "ok"

Then they put the phone down.
Im wishing I had never got this range rover now, its been a drive ornament for 3 weeks now.

Range Rover ownership isn't for everyone - they will test your paitience, your relationships/marriage, your bank account and your life resolve....

They look nice, they sound great when you say 'I drive a Range Rover...' and they are the most comfortable and useful car you'll ever own....

BUT....

There is only a few people who can tolerate the constant attention and problems that a Range Rover will deliver to them....but boy they are worth it!

That's what they are meant for
Unless you can DIY and understand electrics any Range Rover is a dead loss.

I have 3 model T Fords 2 lotus and a CanAm Lola taking up the job of drive/garage ornaments.

This is my 6th land rover product and second range rover, but its the first car I have been completely stumped by.

I don't know for sure but if it revs out of gear and revs in low axle something in the gearbox ECU when in high range is inhibiting the throttle circuit. It's just finding it that maybe a problem. Without reading back through the thread can't recall if you have had diag on it. If not, it would be wise to do so.

I wonder if it's the torque reduction request from the box ECU causing it?

Well its going in on thursday so they can have a look at it. But they didnt think they could fix it.

It depends what diag unit they use. If it's Snap-on or Autologic maybe not, but a dedicated diag should find it. There is a signal not going somewhere or a signal going somewhere that it shouldn't. A good dedicated diag should pick that up.

Its Land Ranger Services so they should have the proper stuff, £45 +vat.

Thanks for sticking with me and helping, without this forum I would have taken it apart and sold it on ebay by now.

Looking through the diagrams it maybe a problem with the torque reduction circuit in high range. Which is in effect stopping the engine ECU from increasing fuel to throttle up. So maybe gearbox ECU at fault. But don't quote me on that one.

Maybe Keith, didn't see this post but have had a look at diagrams and that does seem a likely culprit.

Yeah i know but i had not seen your post when i wrote it, otherwise i would have just added a +1.

merely that you said "dont quote me"

That means it was not a definitive answer, just a suggestion of the possible cause after investigating the system diagrams and write ups.

Well I found a suitable gearbox ecu on eBay, fitted it today and....

Same problem, so it's got to go on the digasonistic now.

Think it should have been on diagnostics a long time ago to be honest. See post #2.

Yes I know you said that, but being an engineer and owning a classic car garage myself I like to see if I can fix things myself.

I was also a bit reluctant to take it to a company that said over the phone that they didnt think they could fix it, but would still charge me the £54 and plug it in.
