I am an owner of LR Discovery II (2002) TD5 manual gear box and I have serious problem. Unfortunately in my country the technicians from the authorized service are incompetent or let say incapable to help me. So the problem is following:
When I change gears for ex. from second to third when I push the clutch pedal in the beginning the revolutions of the engine start rising with about 500/1000 and then star going down. I have been told by the mechanics of the service to change some kind of module which controls the distribution of the revolutions of the engine during the change of gears. I did it but the result was nothing.
I would like to mention that I bought my car with a damaged roof and I believe that this car has crashed and has stayed upside down. In the beginning I had to remove the air from the clutch hydraulic system because the pedal was not working. Now it is OK but I have this problem with the revolutions. The computer is not marking any mistake and that is why nobody knows what really the problem is.
I would be very grateful if somebody can give some advices or to give me direction where this problem could come from.
Thank you in advance.
But first:'do you have the same problem going from 4 to 3rd? (DOWN SHIFTING)
Does your engine react smoothly without delay if you are slowly pumping the accelerator?
If the answers are NO, the potentiometer is OK
You have changed the EDC I understand and therefore the fault most likely is in the potentiometer itself or in the hardware between the accelerator pedal and the potmeter
Your clutch is probably not the culprit.
Thanks again! This saved me lot's of time and $'s.
If I make "down shifting" the problem is more or less the same. When I smoothly
change gears the problem is the same but not so significant. The revolutions are rising with about 100/200. If I am doing this faster and if I push the acceleration pedal hard the rev. are rising with 500/1000. It seems the problem is stronger if I change gears in high revolutions.
What realy is this potentiometer, is it removable part or it is a software. And If I had a hardware problem, would not this be marked by the computer of the car?
Thanks in advance.
A potentiometer is a physical device used to modify the resistance in an electrical circuit. If you've ever used lights that can vary in intensity by turning a knob then you were using a potentiometer.

Well, it seems to me that the problem lies in the pot-meter.but it may also be in the electro-pneumatic modulator.
The EDC has several input sensors:
1.Vehicle speed sensor
i2. Injector sensor
3 coolant temperature sensor
4 boost pressure sensor
5 Electro-pneumatic modulator
6 airflow sensor
7 engine speed sensor
8 throttle potentiometer which may be the culprit
A potentiometer is a variable resistance and normally it operates in the same way as an old fashioned volume control on a radio (rotating movements)
This potentiometer is sitting next to the EDC and looks like a small electro-motor attached with two screws. If this is hanging the engine will react during gearshift as if you are keeping the accelerator pedal down. But then you will also have this effect even when not driving. If the shift is in free and you press the AP (accelerator pedal) and release it quickly the rev of your engine will go slowly down.
If, however, the revs are following the AP it is not the pot-meter.
If the pot-meter is not the culprit I would try to check #7 and then #5
If you send me your email address I can scan in where the different parts are located.
I have to tell you that I am NOT a mechanic only one who has lived with the Tdi for a long time.
Good luck!
Thanks alot for the detailed info you gave me. My e-mail address is nikola.taskov@abv.bg
I have tryed to simulate this situation when the car is not moving and the gear lever is in neutral. Then the problem does not exist. I rise the rev. to about 4000 then I push the clutch pedal but everything is normal. The revolutions are rising and goind down normaly. Strange problem isn't it ))
However I would be very grateful to you if you could send me scheme or the location of all this sensors. Also you got the feeling I have changed the EDC but it seems to me I have changed only one of the sensors. It was a cubic part with some kind of smal red piston. I think it could be "Electro-pneumatic modulator"
Sorry for the ignoranse but what does EDC means?
Thanks a lot in advance.
whine-y side (but not too bad as most V8s are loud) AND I went for my first fill up and the tank will only go 1/2 way ... then it overflows!
My questions:
- How seriously do we take "service engine soon' lights? I had a Ford Contour and the light NEVER went off ... just stayed on and mechanic couldn't turn it off.
- Why's the engine being noisey?
- Why is my gas tank only filling half way?
My sympathy story: I am a poor-ol' teacher and need wise advice from LR experts!
could you please send me the scheme of the location of the parts we have
spoken about. My e-mail is: nikola.taskov@yahoo.com, nikola.taskov@abv.bg
Thanks.
I drove several more miles and the transmission failed. The fluid in the transmission was full but "smoked". The specialist is trying to say that there was something else that caused the transmission to fail. I had no warning of a speed sensor gone or any overheating. Any advice other than "get rid of it". I have a loan on this vehicle and can't trade it in unless its working.
Pulling left ,,, definitely something wrong. First thing to check is wheel alignment on the front wheels. I would guess they are out.
Have it checked (and corrected?) and let us know.
Good luck
As of yet, I only have a few slight problems mainly due to the vehicle being used and covering my bases for it having 78000 miles on it. Everything seems great apart from:
-The three amigos, which pop on randomly and then can be reset by turning ignition to off removing key for 10 seconds.
-The wear on the stock goodyear tires looks uneven but creates no shaking. the dealer is going to buy two new ones but I'm going to wait for another couple thousand miles before I decide what tires to buy.
-The AC drips into the passenger side's leg space and I obviously need to check the drainage lines/clear them.
Other than a few noises I'm not familiar with (Squeaky seats in the rear, whispering air like sound when AC is on), everything seems A O K. I am however checking into the best warranty possible without spending too much (dealer allowed me to purchase base - power train for cost for two years) and also am going to get the Disco checked at a local AAA certified inspection center.
My questions are these; because I'm about to embark on a 1000+ mile haul up north (San Diego to San Francisco and back) which will entail a u-haul trailer on the way down, I'm wondering the following:
-Can I fix the AC drip myself and how?
-Should I be getting a tune job before I go (and for how much)?
-Are there any considerations or things I should be watchful of during the trip (of course there are the obvious; oil level, coolant, etc., I mean beyond these).
:confuse:
Keep in mind this is fresh from the dealer and I have yet to do the inspect with AAA, I have no record of prior maintenance other than that the dealer changed the oil.
Thanks in advance to any responses. I will be leaving on Tuesday night.
Happy Labor Day.
I'm trying to replace the two plastic panels that runs down the A-post against the windshield of a LR DISCO series II '99. I have taken the old ones off and have two new ones with all the retainers and clips but I have trouble in getting the new ones back in place !! is there a trick ? Scared of breaking it if I use force .......
any suggestions ??
Thanks :-)
The beautiful Land Rover Discovery barreled down the 101 North at a safe 68 miles per hour. The next exit was the 85 North, and finally my 8 month pregnant wife had fallen asleep for the past 5 minutes. I clicked the cruise control off and made my exit onto a one lane interchange in the city of Campbell. As I ramped up to the 85 North, low and behold standing dead center lane, spanning the width of the lane (approximately as long as the LR is wide), a wild BOAR lights bewildered with my lights in its eyes. Most likely wondering why his legs suddenly decided to stop moving. I, having two cars on my tail, did only what could be considered honorable and whilst yelling "Oh, My ****ing Lord!", drove straight through the bewildered boar. WOW! Was that the best decision of my life?... Yes. Not only is this accident covered under COMP but it will not effect my premium, Sweet!
So, let it be known that when traveling at a rate of 65-70 miles per hour and confronted with mere flesh and bone, the LR Discovery suffers only aesthetic damages and potentially may require a power wash to rid the under carriage of blood and guts. More to follow, such as pictures, the boar is effectively dead and was checked on by local police. All that the passengers suffered was long conversations with insurance and longer convos with AAA membership supervisors. The LR is at the shop being quoted as I write this. Damages most likely include sub-frame, bumpers, maybe chassis alignment, and radiator/fan. :sick: Unfortunately though, as we drove over the boar, I believe I heard the Disco's ego inflate slightly and it is possible the truck has recognized its own awesome power. The wife and I, have to sit down with Disco when it gets back and explain to it that boar's have feelings too and that we should be more careful when playing with them next time.
Have a great weekend.
Seller says "Oil and oil filter has been changed regularly at 3K mile intervals and recently at 53K miles. K&N high performance air filter was installed at 50K miles. Fluids were recently flushed and replaced at 50K miles. 60K service should be done soon. Rear brakes need new rotors and pads."
What am I looking at as far as costs so I can factor into negotiation?
Looking forward to see the pics.
Give the poor Disco a hug from me.
I am having the same thing on the same car to get a new transmission which should be ideal fro sometime is prety expensive it arount 11,000 $ . and the car is worth less is any body doing repar to the trans. PLS let me know if you come a cross anybody. The other chice is to look for Engine &Trans swap anybody have a suggestion.
:sick:
I cycled the outside rearview mirrors (since they're heated and likely connected) and the rear wiper, all lights work, all functions work, it's just blinking and clicking like crazy.
Any ideas, anyone?
(Hey, Steve!)
If so, the VIN number is: SALLTAM232A737655 and my email address is: jtad1991@yahoo.com
Thank you
1)The heat and the front wipers will not work sometimes. It happens occasionally and always the heat and front wipers at the same time.
2)There were a couple of times that when we put the vehicle in drive the dash instrument panel indicated we were still in park, when shifting the light on shifter remained in park but we are able to drive.
Any ideas of the causes?
irritating incidents. Should theoretically be an easy job to mend, but where to start? :confuse:
The fault with the blower(heater) is obviously a bad connection somewhere. I think I would start with the fuse box in the engine compartment. Take out the fuses and check that the contacts are clean, check that the wire connection on the underside is well connected. Taking out fuse (#12?) will probably re-create the blower fault.
And then you know you have to look for a bad connection. If it is constant, however, it is easier as you can use a multimeter and measure the voltage at the fuse and you will therefor know if the fault is before or after. Unfortunately I do not have a electric wirediagram for the DII, but if you can put your hand on one you will easily find your way, I am sure.
The other fault. Again a bad connection (chicken connection) I would start at the gearshift to see if something has loosened there. Because the light on the dashboard is lit by a switch at the stick.
Good luck, and let's know
help please anybody? :confuse:
