Performance restored on our Discovery 3 with just one £80 part! NO MORE LIMP MODE

In this episode I take on two of the simplest jobs I've ever done on a Land Rover and managed to restore the Discovery 3's full power and eliminate HTCs and limp mode for good...for now! Seriously, if you're getting engine management lights and fault codes, then check this simple trick and cheap part to get your Land ROver Discovery running true again. Quick and easy service of the turbo actuator, and replacing the fuel rail pressure sensor. One hour of your day!

Great tips for the rest of us and another big step forward for your project LR3 Thanks for sharing 🙂

[@flodurpups9846]

Thanks for your loving the disco 3 and the owners. It helps me to understand more and more my lovely car. Beside i drive also a xj 12, 6.0 majestic. Both cars are extreme durable. Be blessed.

I’ve just done the fuel rail pressure sensor mine and wow what a difference no more limp mode thanks great tip

[@rstarsurfer]

Thanks for the videos, the more I watch this sort of videos, the more confident I feel getting a disco 3/4. Just one thought, cover the positive of your battery if you work with spanners close by, :) especially if the negative is still connected. In your video, the spanner is short and may not reach the positive, but could still be nasty if someone does it with a longer one.

[@deanh3741]

Rather than wd40 I’d suggest a lubricant spray with ptfe or graphite additive so the evaporation of the spray leaves the additive behind and doesn’t leave you where you started with sticking parts

[@Rogue-j7s]

I know post 6 month old but do you have name of a lubricant spray what is suitable

Great video my son's gone in limp mode so we're going to try the w40 then see what happens then and see what pops up after that 😆😆 I've got a p38 range Rover with less things going wrong than my son's disco

[@eddieMurphy11111]

I will have to look out for them new cans of wd40 i have some with the plastic straws, great job on the disco thanks for the video

Nice

Did you have trouble getting the sensor off? I am struggling to get mine off.

[@adamprehnal2087]

I have Range Rover Sport with 2.7 TDV6, i want change the fuel presure sensor but i can´t find it. It is not in the same place like in video, there is just plug and the same on the other side. I found some sensore look exactly the same in the back of the engine ( in center under the wind shield ) ant its stick in something similar to the fuel rail. You thing its it?

1:25 I'm getting massive Wheeler Dealers vibes from this jaunty angle, I think their tripods always had one leg shorter than the others.

[@garymv]

Wheeler Dealer vibes ?? Vibes?? In a kinky way? You enjoying it 🤔

[@rustytwinkles7762]

before changing the fuel rail pressure sensor did you have to wait for the fuel pump to stop priming before cranking the engine over?

[@LRLiveUK]

I did let it prime and then checked the valve at the top of the engine. No hesitation in starting.

[@rustytwinkles7762]

@LRLiveUK okay cool, thanks. I was just wondering if you let it primed first, like how i do before cranking. And yeah, mine starts the same.

[@chrissoper8525]

Changed mine for a Delphi one, as was getting limp mode on and off, new sensor was fine until I floored it and on hills goes in to limp mode everytime. The sensor was not cheap £60 so surprised its causing an issue.

[@LRLiveUK]

I'm not sure if the brand we offer but it is OE and not Delphi.

[@carltyler3686]

Im having issues with limp mode but only after the engine is warm. Turn off engine and back on again fault clears for a minute or 2 then limp mode again. Amy ideas. Does throw up p0183 and few other fuel related ones.

[@LRLiveUK]

I'd check the steering angle alignment with diagnostic tool. And change the fuel rail pressure sensor.

Just been given a d3 ...no sunroofs and manual .. Needs new handbrake module and tail gate actator....im blocking egrs at the moment then i will bung it in for an mot

Hi thanks for sharing your experiences. My Discovery 3 went into limp mode at the same time as the 3 Amigo warning light, so I replaced the fuel filter, but there was no change, so I replaced the rail pressure sensor, and all the symptoms disappeared...yeh~~~ But just two days later, all the symptoms came back.😢( limp mode & unstable at idle(engine vibrates) p0087 p2290 Two error codes appeared alternately. Both do not appear at the same time Any advice is greatly appreciated.

[@LRLiveUK]

Sounds like an issue with the fuel pump unfortunately. You can do a pressure test from the valve at the top of the engine in the V towards the back.

[@abchkbh]

@@LRLiveUK As expected, your thoughts are the same as mine. I think that's the only question left, whether low pressure or high pressure is the problem. Thanks for your reply 👍.

[@demonbiker7899]

Got same fault swapped fps and now car has no drive?? Hdc fault suspension dropped engine fault?? Help!!!!

[@LRLiveUK]

I would recommend getting the steering angle sensor recalibrated (OBD tool) And check you're getting fuel to the rail by checking the Schrader valve in the top of the engine

[@demonbiker7899]

@@LRLiveUK seems that changing the fps has made it immediately worse and faults as soon as ignition goes on, going to try a hard reset later and check earths as I’m getting voltage above threshold general failure code for fps now??

[@LRLiveUK]

@@demonbiker7899 I know that some aftermarket FPS units give bad readings. That's why I fitted that particular one. If you've fitted another brand that could be the problem.

No way were you getting 32mpg. The sensor is an input to the calculation.

[@hughjanus3347]

Sorry mate, on a long run I get 32mpg (imp) at about 67mph on the motorway. I've had 34mpg (8.2 l/100km) several times depending on load/humidity/fuel quality)

[@amcrome]

Isn't WD40 flammable?

[@LRLiveUK]

You need to allow the lube to penetrate over a few hours, so you won't be running the engine during that time. Then it'll dry out.👍

[@FunkyDebob]

WD-40 is not flammable and the perfect choice for the job…

[@amcrome]

​@FunkyDebob - ahhh yes it is - just look at the back of a can

[@FunkyDebob]

@@amcrome the fluid itself is not! It’s the aerosol but that is gone after a couple of minutes.

[@Can_I_Kick_It]

Probably should use an actual lubricant rather than multiuse wd40
