Hi guys, sorry I haven't posted in a long time! Last time I was on here I had a P38 Range Rover with keycode lockout (unfortunately this was never fixed so i'm hoping for better luck this time :) )

Right - The car is a 2005 (05) Discovery 3 2.7 TDV6 which is fantastic (most of the time)

Unfortunately it is hesitant most of the time (there is twitching) when changing up a gear, the best way to describe it would be as its struggling to find the gear ( I did think this was torque converter but have been told otherwise) the car is an auto and this happens mostly when under load IE going up a hill but not always.

Having been told by a local car mechanic this was the EGR we went through with buying blanking plates off ebay but had a software guy out who said the problem is electronic as the codes are for sensors!

Still with me? So the car had a Range Rover software on (for whatever reason, possibly has a Range Rover ECU im told but who knows)

After several hours of head scratching we still have the exact same issue!

So to conclude I am told this could be down to the wrong ECU/Software in the car at the moment which is causing confusion between the Enginge/Transmission

I would be grateful if somebody could offer me advice on a software upgrade as I am told by a technician friend this COULD solve the problem. There is plenty of power throughout the rev range, it really does shift for a big car!

Sorry for the long write up guys, any help is HUGELEY appreciated!

Just wanted to add before I got the car I was told the alternator had been done, not sure if this has any relevance or not (just bought it a few days ago) the fault was evident on the way home but not the test drive - so its been like that since I bought it!

simple take it back & get them to fix it or have a refund
 
+1 on the refund.

Sounds like a bodge job

and on a personal level, dont like the wheels, its a Diesel burner not a sports car.
 
The place I would start first is the electrical supply. Modern cars are all electronic and susceptible to problems if the volts ain't no good.

So:

1. Using a multi-meter, test the voltage between the battery pos. and neg. poles; first with the engine NOT running - should be at least 12.60v & then with the engine running - should be over 14V. It's important to do it in this order and when the vehicle has been standing still for at least 1hr.

When you've done that, post the results.

PS This would be a VERY good time to buy yourself a diagnostic terminal such as Nano Evo or Hawkeye v6 - approx £300-350. I don't agree that the only only place to sort out a DIII is at the main dealers at all.

With a car as complex as TDV6 I think if you carry on trying to sort the problem out with local garages and friends you will be going round in circles I know we all try to avoid going to a main dealer but there are sometimes problems that they can detect straight away,as long as they find the problem you dont have to get them to fix it just ask them to diagnose the problem and then you can fix it yourself or get your local garage to do it. My son had one and the electronics where a nightmare so thats what he did
Good luck

Thank you for your comments, I don't have a multi-meter so I will try and borrow one off a friend today and get back to you

Thank you, I will have to look in to getting the car booked in if I cannot find an independent specialist to have a look

Thank you I will look in to getting one ordered, but for the meantime I will borrow it so I can get the readings sooner rather than later as this is the only vehicle I have to use at the moment so really need it fixed ASAP

If speed really is the key, here's what I would do:

1. Put the battery on charge right now for overnight &

2. Check the oil level in the autobox, using the correct procedure.

Thanks Dave, any idea of what it would be worth if I were to sell it?
 
one of the lads that works for me has one! 57 plate, absolute money pit, nice to drive, yeh!!!, not much you can do yourself on em, hand brake a nightmare, sls problems, front wheel bearings, and sups juice, and looks like a van!!
 
Dont give up on it yet they are great cars it may only be a minor problem its worth the money before you think about getting rid of it to get a main dealer to give it a proper check over and then you will at least know if its worth having it fixed you will drive yourself nuts if you keep trying this and that, it will be worth getting it checked over just for your peace of mind and a good nights sleep!!!!!!!
Good luck
