Thank you
Hi
This van came to me with a really weird issue.
With the MAF connected the accelerator would not respond... disconnected, engine light would come on, would run fine, but would smoke quite badly.
During the fault finding I diagnosed a bad MAF, but something else did not looked right... although stationary the van did not rev above 3k, which is actually normal, driving would do exactly the same, no power and would struggle to get to the 3k mark.
Speaking to the owner, I found that someone tried to remove the EGR in the ECU maps... and failed miserably!
Once again, a big thanks to ecutech.info which promptly worked on an original backup I had from this van... once that file loaded, the van ran perfectly...
Hope you enjoy the video.
Any questions or comments, please put them below.
Like always, thank you for watching!
Thank you for your video! I experienced the same problem on Renault Scenic 2 with m9r engine. The car stopped accelerate on go with no error. Having watched your video found the same problem after connecting to the car. By the way I cleaned up the MAF with spirit and the car went well.
Thank you!
That's great!

Another great video! Greetings from Brazil. I'm always here to learn. Nice job! Thanks
That's great!
Thank you for watching and for your comment!
I had a similar issue with my egr.
I would go to pull away from traffic lights or a junction and no throttle input at all... I disconnected the egr one day and it never had the problem again. Plugged it in incase it was a fluke and it had the problem almost instantly.
No more egr for me 👌
My car also lost the 3k rpm limit without the egr
Nice fix Luis, I have to agree 99% of the time I go for genuine sensors specially speacially critical ones 👍👍👍🍺
You buy twice, when you buy cheap...
LOL
Thank you for watching!
@@LMAutoRepairs yes that is 100% true he should have bought the Continental sensor
Very informative. Thanks.
☺️
Thanks!

I have maf issue have p100 and p110 codes , if I remove the sensor plug it throws up another p100. Told the van needs ecu as replaced with known working maf sensors but no joy, the van states constantly on diagnostic a minus 40 degree temperature when it’s actually near +20 degrees, told it’s an ecu issue and the wiring is fine, code displays short to +12v on both codes, electrician checked all and even maf unplugged the air temp stayed the same, when I click on air flow voltage air temp voltage it’s all normal
Great video luis,live data sometimes gets it done,not to forget obd global is a nice way to get rid of substituted values,thank you for great content
Thanks!

Thank you Luis for another great video!!!
Thanks Roxanne!
Any tips for DF046 code? Ignition on trggers code about every two ignition cycles (after clearing). Wondering about Injector circuit. Any help appreciated.
Sorry forgot to say Clio 1.2 16v 2008 with siemens sim 32. Swapped ecu with same part number (obviously no start but DF046 re-appeared on that ecu as well). Any tips/advise?
I wish you were around 5 years ago Luis - This exact problem cost me £2k as the garage diagnosed bad injectors! Which they continued to destroy the head getting them out. 😫
Thats bad...😕
Thank you for watching and for your comment!
It's a common problem on those vivaros primastars and trafics

Dear Luis I have same issue with Audi Q7, they remove DPF EGR and put aftermarket MAF. The engine don't show any code but behave equally. TOP regards
Hi
Thanks.... hope you get it sorted...

Great video, anyone know the name of the bolts/screws that hold it in? I’m missing one on mine. Thanks
Напишу ребятам. Я из России была такая проблема года четыре назад, нужен хороший мастер электрик который проведёт диагностику двигателя в топовые крутые сервисы обращаться бесполезно все пытаются сорвать с клиента денег рассказы доходят до замены двигателя с коробкой. Слава богу я знал такого мастера работающего в обычном гаражном обществе, подсоединил комп и сказал что замыкание в цепи MAF,датчик под замену но предупредил поупать нужно только оригинал не в коем случае не бывший в употреблении потому что к нему часто приезжают с этой проблемой, датчик новый а не работает.Купил оригинал поставил и порядок ошибку снял педалями. На прошлой неделе выскочила эта же ошибка, снял MAF продул воздухом почистил ватной палочкой смоченной изопропиловым спиртом и всё заработало на видимой части был чёрный налёт. Ошибку снял педалями. Добавлю что в такой двигатель как у нас нужно заливать хорошее дорогое масло типа Likwi molli 5w-40 а самое главное заправлять в бак хороший проверенный дизель и будет всё в порядке.
This is a great video.i also have the same problem
Hello Luis, I respect your knowledge so I have a question. When you have this low reading of the MAF why you exclude the possibility to have air leack in the hose of the air inlet to the maf ?
Hi
Mainly because of the fact that the reading was stuck at 15.... if I had fluctuations, then that would be a possibility...
Hope that makes sense....
Thank you for watching and for your comment!
K9k contünental 1.5 dci clio, minimum data 18 but max 90, throttle 90,sensor fault or normal?? Thanks
What is the oryginall number of MAF in 2.0 engine?
for me, it lights up while driving and it doesn't go more than 70 miles, I changed it and the things to do still appear like that?
Any codes stored?
👍👍👍
hi mate I ve got picasso c4 2007 automatic transmission. maf sensor not working. I bought replacement and I still have same problem. I wanted to check the harness .there is socket with 4 wires.the sensor has 5 port connection. how do i check if the new sensor out off car with multimeter .thank you.also in harness there is 12volt and 5 volt.one ground and another one.not sure probable ground for the 5 volt
Is that petrol, diesel?
What engine?
Very difficult to help with so little details provided...

Off subject of the maf, but in mine it only revs up to 3000 rpm if clutch is pressed but will rev freely when not pressed in 🤔
Thanks a lot

Hi man, great work u r doing on the channel..
Got a question for u, is there a website for peugeot and Citroen to buy the factory service info like all other manufacturer ??
Good question... never researched that... and actually never seen it...
I will dig into that....😋
Thank you for watching and for your comment!
Hi, there is one called Service Box. You have to pay for technical information though www.citroenpeugeot.com/content/peugeot-service-box
My 2 cents. Do not neglect a good online search. For Peugeot /Citroen there's some nice "stuff" available. Technical or otherwise. As mentioned service box is a good place to start. ;-)

Very good, thank you! What kind of softwar are you using for diagnosis?

hi luis cold you help me with a vivaro 2009, replaced EGR valve code p0488, now showing p0409 , engine warning light on, surging on exceleration, any ideas please
Hi
Which EGR did you got?
New, used, aftermarket?
Unless you got a new genuine one, I wouldn't trust...
That said, make sure that wires etc have been checked, along with any egr learning procedures available...
Thank you for watching!
@@LMAutoRepairs hi aftermarket EGR, i have replaced two injectors, my van is running alot better, but now amber engine warning light is coming but still runs ok, but if i speed up at 60 mph plus the van goes into limp mode, any ideas please
thanks peter
Yes... go original components to start with...
My advice...
Love the unplug it test doesn't work on some vag vehicles unfortunately 😑
That's true...

My 2.0 diesel shows 28 kg/h at idle im wondering what could be wrong with it, the hot plate or the air temp sensor
Hi
The air temp sensor measures exactly that... the air temp... so, you either have a bad MAF, or a leak or blockage in the intake...
Thank you for watching and for your comment!
@@LMAutoRepairs thanks
If you depress the clutch and then take foot off it'll rev all the way. The ECU needs a positive on off for its first check. Maf was definitely dead....
EDITED.......Did you check the air filter wasn`t blocked before fitting the new airflow. That would show a low reading
Yes... that was not the issue... have you seen the readings with the new sensor?
Thank you for watching and for your comment!
Even without checking the air filter. With the MAF disconnected the engine run almost normal.
Since the MAF on, MAF off produce different results, that automatically exclude the air filter and pipes connecting to it. ;-)
Cheers
Great thanks

WHAT SCANTOOL ARE YOU USING AND THANKS FOR THE VIDEO !
Renault clip...

What does the flashing service light mean is that oil related or engine light yah always use oem parts

I have a traffic 2.0 dci 90 hp 2011 The injectors are no longer recognized by the ecu, so that it drives in safe modes and the dashboard indicates serv and the glow plug burns. The injector codes give AAAAAAA on and I can't enter the original I jector codes (it won't accept that) The car does not smoke and runs fine after starting for 30 seconds, although the message on the dashboard has not gone away. I now wonder if you can reprogram the ecu and that I send the ecu to you or if I buy another ecu and mount it. Is it even possible to install a used ecu or do I always need a code? I live in northern Germany so just driving by will be problem
Can you advise/help me
Greetings koen
Try a different tool... make sure you are entering the correct codes... seen many time people trying to input the wrong codes, which obviously the ecu will reject...
👍👍👍
Ecu beyond repear??
Vin number ist all so not there anymore ☹️
@@carpfever683
I never said that...
If another tool fails to do it, perhaps a reflash and try again...
👍
@@LMAutoRepairs
OK
Howe too reflash? Ist that new software?
Now the Ecu don't find the Vin number anymore. 🤢🤷♂️
I sent the Ecu now away too check!

Yes, that would be a software reflash/update...

Hello, bought a new maf sensor, car wont start, everything connected well, any help please?
Does it start with the MAF disconnected?
👍👍👍
@@LMAutoRepairs It starts only when im pressing half the gas pedal, does the same when connected. Tried to disconnect the battery still the same. When i install the old one it starts normal.
I think you answered yourself...
If starts OK with the old MAF and not with the new one...
Why are you replacing the MAF?
Is the new MAF a genuine or aftermarket?
@@LMAutoRepairs Changed the maf because i tested it and when i accelerated, the values didnt move, its standing on 3.04 (aspirated air). The new maf is a new one, not original, it's from PIERBURG manufacturer with same codes as the original one.
And on diagnostic is showing aswell error codes p0100 and p0110, thanks for your help, well appreciated
The previous shop couldn't figure that out?
i see it a lot. Most garage only read codes or have badly diagnostic tools or just don't know how to use it (or live data)
🤔
I guess not...
Thank you for watching and for your comment!
Guys pls help I have been struggling with my Nissan primaster the problem is when you rev it's cut off what's the problem is pls help
My glow plug coil light and emission light has come on. Could this be the cause? Although the van drives fine.
Scan the van first... before start to throw parts at it...👍👍👍
Thank you for watching!
@@LMAutoRepairs Which scanner would you recommend for a non mechanic.
I guess it all depends how much are you willing to spend...
@@LMAutoRepairs Hi still trying to find OBD scanner for the van. What would recommend for under £200. Something that also can be use for other vehicle.
@@ClankyRochet - Budget being an issue and for light amateur use.
Get something like "TORQUE PRO" for your smart phone. There's a free, light version, but do yourself a favor and step up to the PRO version.
Associated with a cheap Ebay Bluetooth ELM327 interface it should give you the most basic information. Notice it has nothing to do with a professional level tool. But you'll have access to the basic error codes and the capacity to read/delete them. Some live data usually can also be accessed. But I reiterate it's not a professional tool.
What is unbeatable is the price point of such solution. We're talking less than 50€ all together! ;-)
Regarding the glow plugs. Have it sorted ASAP. It's rather cheap considering the alternative... Like a clogged/damaged (read expensive) DPF! LOL 😂
What's the purpose of limiting revs when stationary?
For many reasons.. fuel economy.. protect engine from getting hot when it is stationery.. high revs harm the engine (rings of the piston) .. transmission also shifting from park to drive or reverse with high revs ..etc etc
Just what I was about to say...
👍👍👍

nice troubleshooting,as usual lol;
--nice-- way to build cars,no doubt; any nick nack shit leaves you stranded ; this shit that is going on with the cars all over, really needs a kick in the ass...of the GOVs,of course, no one doubts that the manufs *know* how to make cars, if the GOVs only let them...
Before any unsupported rant exercise. I truly advise you to look at a few photos of major cities in the late 60's and 70's. Covered and totally dominated by smog. While realizing people were living in those conditions DAILY!
Check and compare the values of emissions of a vehicle of that era. Check and compare the consumption. Check and compare the power output...etc.
Surprising or not there's a lot more to see. But that alone will give you the overall "feeling" of how much things changed.
Than the "nasty" gov. mandated exhaust cat. EGR, DPF, MAF and the vast etc. that we can find in a modern vehicle don't seem so bad anymore!
Cheers
PS: BTW it's worth a small clarification the gov's don't mandate the equipment itself. What is mandated is the admissible emissions values. Manufacturers have to come up with the "solutions" to comply with the mandated values. ;-)
@@crpth1 Cheers;
1-emissions: better now by a long shot BUT they CONTINUE on putting more and more lipstick on the pig, VERY expensive, the time to stop that polishing of a turn has passed already,yet the Greenpishers are relentless,with the gutless GOVs following that new religion, and improving on it!
2- consumption: about the same, but in A LOT of cases,worse,because of 3: ( more power,MORE consumption; a Veyron's HUGE fuel tanks will run DRY in only 16 minutes at full speed of 400 kph!!
3- power: STUPIDLY made cars!!!!!!!!!!!! 200 hp from 2000cc engines, meaning they are race engines with plates; very UNPLEASANT to drive because of shitty torque before the STUPID turbos spool up ; fuel consumption is bad at slow speeds because of that; and 300, and 4 and 500 hp to drive the speed limit and to go around the corner get some groceries ?!; and HUGE and heavy cars and trucks just for status?! environment?! totally OUT OF CONTROL, nobody REALLY gives 2 shites about the environment,ONLY about being re-elected; if they did, they would mandate that when turbo cars were made , an EQUAL amount on NON TURBO needed to be built also; except in Germany,where that needed to be way less than 50pct, because they have 12000 kms of highways with NO speed limit; 300 kph is ok there,and you NEED turbos for racing and SPEED (and towing,etc),but NEVER for a daily driver!!
Vw for instance (all others too!) state that with so much GOV mandated shite , this shite costs now more than the engine itself and horrendly increases prices, complexity,breakdowns,lots of EXPENSIVE parts replacements etc; the warnings are out, but they are falling on deaf ears, the Greenpisserpushers Al Gore followers are in command now, GOVs don´t know shit fron shinola, it's a whole new religion going on until all our faces,and feces, come out green.
