2012 RANGE ROVER 5.0L - MIL ON BUT NO CODES (ROUGH IDLE ONLY WHEN COLD) - RESTRICTED PERFORMANCE 

Mario, it's safe to say that the owner of this vehicle will be a customer for life, as will his/her kids and neighbors. You're a world-class guy.

Great video brother. Definitely not an easy diagnosis or repair on that thing.

Good job Mario , I have run in to this once , after doing a headgasket job on a 5.0 turbo , I never touched the fp chain so I figured i didn't have to reset it after assembling back . When I started it and test drove I got that message came up for reduce power . The chain had jumped 2 teeth 😬 and I had to go back in there for the second time 🤦‍♂️ . This video was like dejavu for me .lol . For 2 weeks I had nightmares . Keep up the good work brother i feel your grind 💪.

Outstanding. I’ll take it. The master technician strikes again! Thanks for sharing.

Heck of a find Mario! That doesn't look like a small job at all! The main chains are fairly common failures, right? But I never heard of the fuel pump chain stretching on those! Heck of a find.

Mario. Thank you. You have a gift. I’ve been fixing cars like you for a long time. I always and learn from you. Thank you for taking the time to teach us

Nice work Mario. Cool to see you tackle something a little unusual, and come up with testing methods on the fly. 👍🏼

i called the approval. as a fellow L322 owner i kneww the clients loved that machine. we L322 owners all have heavy hearts and light wallets

Appreciation for the amount of work and time involved off camera cannot be over stated. Great job Mario . Lots of confidence required to take on a jigsaw 🧩 of that size for the first time . Cheers man. 👍👏👏👏

Mario as always brother great video! Great to be able to see a diag all the way through till the end. Badass diag and repair!

Mario, this video was very good as I work on Rover's myself. I ran into a similar issue with a 2.0 audi that was building too much fuel pressure and the chain was off.

Wow! That was a huge job! Outstanding work, sir!

Awesome diag perfect way to follow the data, experience definitely shines through 👍🏽

amazing work . thanks for following through

Outstanding work as always!

Wow brother that's nuts! It's kind of crazy these fuel systems with so high of pressure - give me a single fuel pump scenario any day! I love your videos, good job bro!

Thank you very much for the information

Looking forward to watching this after work tonight, working in Jlr here in Ireland we rarely see and 5.0’s only generally 2.0 3.0 Diesel’s which generally only either have a cracked dpf/scr or have just blowen up .....!

Great find Mario!! This is a great instructional video.

Thankyou for taking the time to make these videos

Awesome Diag Bro👍 Indeed it makes a Tech very happy when seeing best results on such a complicated repair, nothing is better than that feeling😎 Your plan of attack on this one was perfect, your videos are always loaded with Info on diagnosing these systems professionally, great work Bro👍 Stay Safe❤

Looks like an exhausting job, mentally and physically. I really enjoyed the diagnosis you did Mario because it was news to me. Very cool video and I hope I never get to enjoy that "fun" you had! haha

Wow! That's why you are Super Mario! Awesome job!

You’re good man. I need to learn not to panic and look at the data. Thanks bro.

Great diag! Love your out of the box thinking.

Very hard diagnostics and repair. Well done.

WOW! Fantastic job, Mario! No doubt one expensive repair, but the customer should absolutely be thrilled their vehicle is now right. PS: don’t beat yourself for initially speculating it might need new pump(s). You ultimately made the right call and that’s all that matters.

Great information

Good diagnose video , another one fixed good job man , we are ways learning , good to see you , much appreciated Mario Thanks Rob mobile man

Excelente trabajo Mario, por desgracia la falta de información es algo con lo que ha veces nos toca lidiar en este trabajo, me ha recordado a una conversación que mantuve hace unos meses con un ingeniero y amigo que me comentaba que hay por lo menos 6 tipos diferentes de sistemas de inyección GDI contando tipo de bomba, tipo de regulador y regulación de la eletroválvula. Muchas gracias por compartir.

Thank you, Mario for the time and knowledge good video

great job mr Mario.

Hell of a job Mario. You must have been on that for days!

Amazing job!!!

Excellent

Jesus Christ that escalated quickly ......!

Top Man , outstanding job

Good job Mario, I had a similar scenario about two years ago it was a real pain. More grease to your elbow

Holy cow batman , great diag Mario, I would have ran for the hills lol , your talent is inspiring!!!

Fantastic work, always interesting to know these idiosyncrasies of the RR V8 engine, I own a supercharged L405 and I am always paranoid about my engine.

Wow!! amazing work and video big bro

Another good video mate 👌 good find too 👍

Great job thanks for cheering

Good Job ...

I just did the timing chains on my 5.0 Supercharged Range rover. One hell of a job. But she's running real good now.

Bravo veliki je to posao i treba dosta vremena i zato se mora dobro i naplatiti toliki trud.

Hi good video bud thank you for sharing. Man this makes me nervous! I am having similar issue with oscillating rpm while driving, not really at idle then some sputtering off idle not idling in my 2012 supercharged. Been to a few "specialists" and spent plenty with parts changers, an embarrassing amount of money with no improvement. Wish you could have a look.

Mario, you are AWSOME as always and very good information ur sharing. cheeeeeeeers

Good job mann :-)

I have seen the no codes with a CEL On in a much newer BMW...2017 I believe : I think it’s a scantool problem. Didn’t have another scantool to check,but checked the car a few days later with the same scantool and the code was there : something about the radiator shutters...

good job buddy.....

Competent diag bro 👍

That is a massive job. I was under the impression that the body has to come off to remove the engine on those. Is that correct. Well done anyway. I wouldn’t have fancied that one!!!

Wow! Intense! That is one heck of a job. Yes, you were wrong at 1st, but how you handled the rest of this job is amazing 👏 Making up your own tests... having to find a way to pinpoint the issue. "We'll call this fun". 🤣🤣🤣 I totally get it. Only because it ended well.... 😉

wow 💪👍🏻👍🏻

Great job man, if you don't mind me asking, how much did you charge for it? Trying to get an idea since I'm doing a similar job.

First!

Brilliant diagnostic, must remember high pressure check timing, cheers Mario, Sandy

Great job, that poor owner . . .

that not easy one to diagnost.thank

Great video is there anyway you can go over the fuel system and the regulator valve test again I didn't understand that

Mario, thank you for the video. I’ve just started taking an ATTS fuel system diagnostics class and this was very helpful. What pressure should the high pressure pump be putting out at idle? Man that is a lot of chains. Does that pump run off the crank or cam? Lucky those weren’t worn. That was a job and a half. Nice work and nice troubleshooting. Hope it lasts. How many miles on the replacement engine? Guess thats enough questions. Only answer if you have the time. Thanks and stay well and safe 😊😊😊

I was able to manually jump teeth on that one (fuel pump chain) once with a plastic wedge and put it back in time.

I play with my tacoma GDI system. At Idle desire is 0 psi but you can see 450 psi at the rail and is normal. If you leave the car Idle for 15 to 20 min the pressure can get up to 780 psi just idling. But man that's a lot of work my guess is 20 to 30 hour labor time.

Samcrac loves range rovers! He's done with it. Horrible cars. Nice job mario.

👍👍👍👍

Hi, this is a very detailed diagnosis and repair. I am a DIYer and I also own a 2012 LR4 same 5.0L NA engine. Mine is sending codes related to catalyst and emission misfires and no misfires in the cylinders with fuel trims within normal range. You are an excellent mechanic and I would like to ask your guidance on how to go about solving the check engine codes. The check engine light comes on right away as soon as I start the engine. After I clear it with my GAP tool, I can drive up to 10-20 miles without check engine light; however, as soon as I turn off the engine and restart, the check engine light comes on again. I hope you can give me an insight on what's going on.

How much did it cost the customer if you don’t mind me asking? Great video!

Out of curiosity how does the pump timing effect that fuel pressure....?

If you had that Fixd diagnostic dongle it would have told you the fuel pumps were out of time and the chains were loose. 😂 just kidding. Good job Mario. We appreciate you buddy. Have a blessed and safe week to you and your family.

wow, made me wonder why the car diagnostic system failed to tell you what is wrong. I would expect it to tell you if some thresholds are too high. Hope the newer models have better diagnosis system and less complicated design :) anyway, great video mario :)

Hey bro!! Just found out about your channel and spend hours watching. You are great!! I did have a question....how would you check if there were any bent valves before replacing chains??

Did you grin a bit when you saw fomoco stamped on the cam phasers? i shure did when i id one of those!!!

hi there sir amazing sure need the right tools as well you should be a teacher. wow i bet that cost a few quid nice job well done

How did the engine come out Mario? Through the hood or underneath? What a big job by the way! Dang

I keep getting a cylinder 5 misfire code for even on after a fuel injector and spark plug job filters and Mafs. Only on idle when starting. You can barely feel it. Anyone have any idea? It’s on a 2011 Range Rover supercharged.

you may what to have a conversation with a tech. over at flat rate masters channel ; he does all the Range Rover work at that shop (or did). As mentioned by FRM in one of his videos.

Hey how you doing nice tutorial, my car is doing rough idle, when am in traffic on just not moving, and I just had the head gasket all 8 injectors all 8 plugs new water pump new fan new thermostat, and it's rough, do you have any advice for me, garage said I should drive it that the ECU will start to recognize the new fit part any advice ? Thanks

Hey bro a 2015 range rover evoque diesel engine, it has a pressure pump right

I think it's going to be something to do with the GDI system

How is it possible they would program in a no code condition when there were so many conditions which could have set codes?

Ya that looked like a real pain in the ho ha wouldn't want to have do that one what was the time on that just wondering

Seriously big job. What’s book time on it?

Is a one of the most expensive engine on RR ? And still not as reliable ??

Hoisted engine out or lifted up the chassis? When the pump chain is so loose (14:30), it is not a chain stretch? Maybe chain guide or its spring is broken? If it is the non-spring side of the guide, u might be able to just remove it and set timing and put in a new guide.... Otherwise, yes, pan needs to be dropped and that stupid pan is bolted on by the rear main seal plate.. ha which means engine and tranny to be separated. I know how painful it is to work on these tanks. Everything is heavy duty.

I have had a few newer Range Rover vehicles go to restricted power because of low fuel level, a new strategy to protect the pumps from running dry?

That would take out some bussiness shops. 😄

I would bring my car to you FOR SURE !!

Grade A, A1

I have the same issue with my 2012 rover. Where is your shop?

your location?

You should use Autologic for this Rover.

dude how many hours did that job pay?

You are going to hate yourself if you have to time the motor. Don’t expect any service info help from LR.
