I had the same problem - the LR dealer changed the sensor on the front left wheel and reset the computer: it was the sensor on wheel
AnswerYou will find that your traction contol has failed or your abs system has a failure, probably a sensor on your wheel or the abs module ,regardless ,it needs attention.my disco is in for same problem at the moment ill keep you posted on the exact findings. Rob... Answerit was the sensor on wheel AnswerRob here again .....back to dealer 4 times ,excuse after excuse,water on sensor, loose sensor ,oh you have a problem....modulator faulty. we will and did replace .three months down the track. the three amigos. abs tc down hill assist lights back on. my opinion? Do not buy any disco that that has those lights on,it seems to me that it is a very common problem with landrover vehicles it costs heaps to fix .2000 odd dollars and landrover pretend its not a problem. Oh i never heard of it before they will say.freelanders also have this problem or one similar.Get real Landrover! A recall is needed, its your brakes that are playing up,iwould love to see or here how many people are having this problem.Rob
AnswerI have a 99 dico II and same problem. No one seems to know what it is or how to fix it. Everyone just wants to charge you to do a diagnose and tell to take it to the dealer. Next time ill buy a cheap SUV. AnswerGenerally when this happens you will need to replace your front pads and rotors with LandRover parts, also for assurance if the code is for a certain sensor it will need to be repalced with the newer style that eleminates the abs sensor connector. The other cause of these lights can be the shuttle valve in the abs modulator. your scan tool schould tell you what is going on. Answertake the vehicle to a Land Rover specialist. not the dealer. have it checked to see the problem. alot of chain part stores have the obdII scanners and they will scan the system for you. most don't charge to do it. they want you to buy the parts there. the common factor of all three lights is the sensor. the next step up is the CPU. One thing to check on all rovers is the electrical grounds. Mine has four different ones. They can loose the ground on one and can cause similar problems. You may also want to check on landroverforums.com. lots of good info. lots of people that are smarter than me. hope it helps. duboffANSWER
If you don't use your Traction control, Down hill, you can also turn the damn lights off. I think that I put 2000 bucks into this before I gave up. I simply unscrewed the dash, pulled the plastic cover and put fire resistance fabric in the holes where the lights are. Guess what? No problem.
The real answer
the three amogos are usually caused by the rusted or damaged reluctor ring on one of the wheel hubs, the speed sensor cannot determine the correct wheel speed, it sees 1 wheel going 60 mph and because the sensor thinks the other wheel is going 65 mph, so the computer sends a fault code.....so the warning lights come on..........your abs and traction control are at odds with each other......thinking the wheel is loosing traction or skidding ? So you get the lights.....the hub or speed sensor must be replaced.........the trick is to find out which wheel or hub has the problem, the tolerance is critical with the sensor because it "sees" the wheel speed by a frequency of the wheel spinning by the sensor and reluctor ring........not a job for an amateur repairman.......it's your brakes ....do it right, is it worth risking an accident ? ............ it could cause an accident that is much more expensive than leaving it go, .......and blocking the lights out of the dash module is just plain ignorant the problem still exists that's how someone gets screwed...that rover will be sold to an unsuspecting family that does not know better.......can you say LAWSUIT?

Can you cut the wire to the dashboard for the warning lights on a 2006 Passat?
I could cut that wire but I won't. It would be a stupid thing to do. The warning lights are there for a good reason. I will fix what is wrong with my car. At three o clock in the morning I will simply drive past the idiot on the side of the road in the broken down Passat who cut the warning lights and let his engine blow up.

Warning lights on Land Rover discovery?
There are many different ones on the dash. They are colour coded as follows: Green: Informative. ie. signal lights, trailer light. Yellow: soft warning lights. The vehicle can still be driven, but there is something that you should be informed of or possibly have checked. ie. service light. diff lock light. Red: serious warning lights. The vehicle should be shut down and parked. Have the matter attended to immediately to avoid damage or incidents. Have it checked by a professional. ie. low coolant, low brake fluid. Blue: Reserved for your high beams. This means your high beam lights are on. Turn them off for approaching vehicles. For specific warning lights, refer to your Owners' Manual, or post a description.

What is wrong with a car if the lights go up and down?
If your car lights are getting brighter and dimmer its probably do to inconsistent charging from your alternator or your alternator is insufficiently charging. To test this start your vehicle and test the voltage across your battery terminals ( pos test lead to pos battery terminal ) it should be approximately 14 volts if your vehicle is a 12 volt system.
