Hi
This 2013 Megane 1.5 DCI, came to me with a couple of warnings, low on power and with several faults stored on the ecu.
The owner had previously replaced some sensor, trying to fix the issue...
A few tests and some logic, and problem was found and repaired!
Follow me on this video to find out what was the problem and how to resolve it.
Next repair on this same car:
• Renault Megane IIl fro...
Hope you enjoy the video.
Any questions or comments put them below.
Like always, thank you for watching!
How it bothers me when the customer does not put enough diesel!!! Luis, you are the best !!!!
☺️
Thanks!
👍👍👍
You are so lucky to finish all that work with fuel warning light on
☺️🤣
👍👍👍
Great fix and video. Some people are too slap dash. Glad you said it straight - the guy lied! Or at least waffled on something he didn't know about. All genuine parts should have the correct connection fitting! Even third party components try and have the correct fittings. Probably threw away a good sensor since it was the blockage. I always keep the original parts, so if new part doesn't fix problem, I will return new part. Before that, I would test to confirm before firing the parts cannon.
Absolutely...
👍👍👍
Nice job in diagnosing Louis. Not only for french vehicles blockage of steel pipe is normal thing and rubber on the end of it is normal. They often fail only at rubber pipe. This is normal day in service when someone reads the codes and after that changes the parts without testing. Btw this sensor is probably oem as renault changed this part for newer design. But the flaw was they did not sell the new plug with newer type of sensor. It is good thing that you didn't need to mess with finding the right connector for sensor.
Those pipes are a bad design and the newer style ones are just as bad!
Normally if the end of the sensor is corroded / melted pipe is clogged.
If you're lucky you can unblock them like louis has but I've had the misfortune of replacing quite a few of those.
☺️
👍👍👍
you know this has become our movies, you are one of the best technicians I watch on RUclips , I do believe that continually watching staff like this every day will make us competent technicians.
☺️
Thanks!
For watching and for your comment!
👍👍👍
Weak battery so stop start deactivated. Do battery resistant test. Great vid as usual thank-you.
☺️
👍👍👍
You can also check the pipe is blocken by holding a peece of paper above the pipe while geven it some trottle. If the paper moves, the pipe is open.
Been to my mechanic for INJECTOR SYSTEM CHECK, POLLUTION SYSTEM CHECK and exhaust gas lights. Diagnostics reported an error: Lost signal on the air connector. Error canceled and everything works again. Without warning, the cruise control works, the speed limiter works and everything else. Without any errors. The mechanic says that due to the vibrations from the bad road, the contact, i.e. the signal, is currently lost on one of the air connectors.
Great diagnosis and resolution work Luis. Your honest assessment in car tampering and correction makes watching car video so entertaining. 😊
☺️
Thanks!
👍👍👍
The most common fault with this engine. Same happens to Nissan Juke & Quasquai. Seen some people take the who pipe out and heated it up with MAPP gas to burn off the carbon build up inside. Takes ages doing it though.
☺️
👍👍👍
Surely it's cheaper to replace the pipe.
@tonymorse4573
If it comes out easily... probably.
And even then, not sure if it was actually cheaper...🤔
👍👍👍
Why, oh why do they leave the fuel in the tank knocking on empty knowing that you will be road-testing their cars, really annoying!
It is indeed annoying...
😬
👍👍👍
I was thinking that aswell
In case they fail the mot & it's scrapped. My renault 1.5 dci is due it's mot next week, I have random emission light that comes on then dissapears for a few trips I have taken it on a few runs with additives. It's still random but I am not tight & at least put in half a tank when it goes for its test.
Good methodical diagnosis as always a common issue on them engines and best technique to clear the blockage no parts needed 😅
Absolutely...
👍👍👍
Nice diagnostic. This is a super common problem on these 1.5 engines.
☺️
Thanks!
👍👍👍
Done a fair few of these for this fault now Louis.
The Nissans are the same story with them being the same engine.
☺️
👍👍👍
DTC926681 tends to be bad LIN bus to the alternator, UPC falling apart, or alternator (voltage regulator) itself.
😊
👍👍👍
As soon as i see the engine i was screaming......blocked pipe.....lol
See this all the time
☺️😅
👍👍👍
I don't....Let's just say think much about Renaults, but it's quite obvious that sensor indeed is some non-oem stuff, also quite half-assed wiring there 🙂. It's weird why people just don't say. I'm machine mechanic and do some minor stuff for my cars within reason/time and if I'd try to solve problem, I wouldn't hesitate to say workshop guy at all "btw I tried this thing X". Actually if I leave car for repairs I always try to describe what and how the fault "feels/appears", let them know codes that have appeared and tell my speculation emphasising that it's my speculation.
Anyway good job. I wasn't waiting that pipe to be blocked. Then again, that kinda long line with sensor just put there..
☺️
👍👍👍
The battery current sensor is disconnected to disable the Stop/Start system that you do not have to push the button every time you start the car. That is done by purpose..
Coworkers girlfriend has a 2015 meganr 1.2 and she complained about how anoing the system is. I gave him the tip to disconnect it.
Recently she went to a service and they reconnect the sensor. She ring him, the car is dong it again. He disconnect it again.
Possibly...I never checked it...
👍👍👍
Headache of Renault Cars never ends until you sold it
😅
👍👍👍
Hello sir i am from india, i am having same engine hazard failure in my Renault fluence can you please tell what should i do ? Shoul i clean the vaccum pipe ?
Worth a try...
👍👍👍
Thermoplunger fault can cause dpf regeneration faults, im sure its used to load the engine during regen.
Never heard of that one before...
But might be possible...
👍👍👍
No, SID30X do not switch on thermoplungers in regeneration phase.
@@moldovanandrei7008 I know the Juke and quasqi 15.dci do but they are sid310 so must be ECU or model specific.
🤣🤣🤣🤣 If you would listen to clients and believe what was " repaired and replaced " we would only need to perform resets and adaptations. That would be our dreamjob Luis .(edit) It get's even better. Luis robbing brake cables from his girls 🤣🤣🤣. All kidding aside👍👍👍Luis. AS ALWAYS.
☺️
🤣🤣
Sometimes you need to do what it takes to get you out of trouble...
The scooter still here... you never know when something else from it will become handy...🤪
👍👍👍
@@LMAutoRepairs True. You never know until you have thrown something away. We have a portion of the attic above the garage full of things that haven't seen daylight in years but we keep adding to it because maybe, just maybe the day will come that we need something. And probably we have by then forgotten that we have it.
☺️
Have this car, good to know if I ever run into this! Thanks for uploading these.
☺️
Thank you for watching and for your comment!
👍👍👍
So was the pressure sensor faulty or not from the values dropping off after applying pressure with the pump.
Sensor was good...
Or seemed like... as the car was happy with the values.
I guess was just the sensor reaching its max reading...
But being an aftermarket...
👍👍👍
Very common problem on this engines , carbon build up and chocking metal pipe and damage sensor . Always replace pipe
A cleaned pipe is as good as a new one...🤪
👍👍👍
You are a proffy👍 my Megane 1.5 dci has sudden excessive fuel consumption from 6.5 L to 10L /100km, no error codes can be detected. Could you please advise me what I should check on the tester? Thank you!
Hi LM! I got same a problem, after full check with Clip diagnostic, Mechanic guy say problem with westgate of turbo charger.
Good video those pipes always block up
☺️
👍👍👍
That's the pipe you put your dpf cleaning fluid thru, I would have been good to do that last the dpf was probably starting to block up that's why the soot then pushes back up that pipe, any ways good job hopefully it will do it's own regen after he puts some fuel in another reason for not regening.
☺️👍👍👍
Great one Luis, actually the owner could have had you proper diagnose it first time rather than butchering up that loom. He could also have read that datapid with his mickey mouse obd tool...but that's were real expertise comes in!
☺️
Indeed!
👍👍👍
Ah, french engineering, putting a pressure sensor on a hose. :)
☺️
😅
👍👍👍
Unfortunately almost all manufacturers do this
Ciao,dal tubicino deve uscire aria?
Praticamente soffiare aria? O tira aria?
Nice work ..but as alwayes your videos is long 😅 .. i have more than 12 notifaction today .this video take a lot of time
Have a simlar thing with mine, one of the sensors gone, but renault dont sell them any more...
Hi Lewis how are you find i will to be good
Can you help me please
I have I problem of electronic power steering open Astra J 1.7 cdti 2012 years
Can you give in method how the reprogramming EPS Opel Astra J thanks for help
Hi
Don't think I ever done it on that car...
I would guess SPS will do it...
Not sure about other tools, would have to dig into it...
👍👍👍
Never drive diesel with tank lamp on!
Guys, I have a question... Is it possible to add or spray DPF Cleaner through that pipe which is connected to (upstream prusser sensor), to clean the DPF filter?
If the pipe is not blocked, yes...
👍👍👍
Thanks very much ❤😊
What is a thermal plunger is it important.. that's good to know do much cars have them I wonder how many minutes they take off heating up the water
To be honest, other than renault, haven't seen them on many other cars...
☺️
Omg thank you i was asking you 2 weeks ago about this problem
☺️
👍👍👍
Oh yeah, good 3 sleve job at the end 👍
☺️
👍👍👍
Another xjob why oh why do they always drop cars off with dodgy parts, no fuel, no blood good batteries. On to the next😊😊😊😊😊😊😊
☺️
... on to the next indeed...
👍👍👍
Hello mate. When does colour come right on engine oil after an engine flush. Is that oil gone to waste that is white colour. I have put new oil in, but the colour is not changing yet.
На моєму Мегані 3 1.5 дизель виявлено помилку Р0089 по регулятору тиску палива, але авто без проблем запускається і експлуатується. В чому ж тоді справа?
Nice one again !! Nearly 1xx K 🎉🎉
Thanks Louis 🙋♂️🙋♂️
☺️
Thanks...
Getting there!🤪
👍👍👍
Hi and thank you for the videos . I have problem with my car and I hope you can help with some suggestions.
For one month ago the engine stop hazard started to come on. And The DF197 code was present first (fuel pressure information, mechanical fault) and then the DF1012 code (consistent multiplex signals for CC/SL.
So changed the fuel pressure regulator sensor, the o2 sensor the thermostat and the cooling temp sensor and the 2 vvt valves and all of this was suggestions from mechanics and I still get the fault anyway.
I took the car to Renault after all diagnostic they said they can't find anything and suggested to get ride of the car.
The car is a renault clio mk4 1.2 tce 120 2013.
So please 🙏 if there is anything you can help iam realy thankful.
Hi
If the car has been at the parts cannon, it is difficult to suggest anything...
The only thing I would say, is that if you have been installing aftermarket parts, they might have contributed to the fault to remain... or might not...
Without checking it is difficult...👍👍👍
Well done... The repair would have been so much easier if the owner hadn't fiddled with it and then to not tell the truth must have been infuriating.
Yes... it is at times...
👍👍👍
I have megane 3 1.9 dci 130, i have the message check injection when i drive for 20 minutes or more and the speed limiter doesn't work when message appears, when the car is cold the message dissappear.
Scan the car and go from there...
👍👍👍
Thanks Louis,, great job Keep up ur good working,,👌💪
☺️
Thanks!
Hi there what was the stuff you put down before putting the wire down?
As I said in the video... diluent...
👍👍👍
Nice work Luis!!!
Thanks!
👍👍👍
Nice work Luis
☺️
Thank you!
👍👍👍
Why does it say engine failure hazard when it's nothing major
🤷♂️
Well, the DPF if completely clogged, can cause some damage...
👍👍👍
@@LMAutoRepairs oh never knew thank you.
Hi Luis, wud u be able to help me by tell me the cost of the touchscreen infotainment system on this vehicle.. I've got the same car, only here in India it's know as the Renault Fluence.
Don't know...
I am not in India...
Have you in places like eBay?
👍👍👍
I meant what wud be the cost for maybe a used 1 in the UK.. I cud maybe ask some friends out there to courier it to me.. eBay is non existent here moreover nobody on eBay ships to India. Hence asked.
@amnesialen
Fair enough... but you car surely access eBay UK navigate and see the price...
That way you can make sure you are looking at an exact match to yours...
If you have the part number, I look for you...
@@LMAutoRepairs Thanks.. Sure will look it up and revert.
Nice work
Thanks!
👍👍👍
Good job
Thanks!

Hi Lewis great content! How do I contact you regarding a cluster issue that I got? Cheers.

Go ahead... I will do my best to help...

Why do people give you car's with literally probably 10 to 20 litres of you in the tank that's no good.
☺️
Go figure...🤷♂️
👍👍👍
Please stop assuming everyone knows what you are talking about! What the hell is a "DPF"???
I don't assume that everyone knows, but I would assume that everyone would want to educate themselves before or after watching a video like this... and definitely before commeting and highlighting that they dont know...
A 10 seconds Google search will give you the basic information you need...
DPF = Diesel Particulate Filter...
Thank you for watching!

jsi borec.ale pro obycejneho cloveka je to nepouzitelne
Every car not fuel ! This is not koincident.

It is a conspiracy against me...🙄
