Thanks for the advise, being a fitter aswell, I enjoy watching your videos and it's a great reminder not to ever buy a Daf ... lol.
I'm glad you enjoy the videos buddy 😎👍
Good work
Cheers rich! Nice to see you made it over onto my channel.I See you help alot of people on Facebook with the DAF product 👌
Very good
Thank you for your comment
Interesting
Nice info
Thank you for the comment 👌. Hope it helps out some time 😎
The breather valve on the ECU causes problems because all kinds of dust get into the ECU and affect the print diagram. I my case ; I rode a lot of zinc minerals during that time and the dust was corrosive. My engine suddenly stalled going downhill and even after resetting it wouldn't start again. I had to be towed to a workshop in Sutton. After installing a new ECU everything was back to normal
😍😍😍
In my case...in Mauritius many daf truck mainly paccar engine..is getting some braking issue failures
Layed on my back in a dark layby last Xmas Boxing Day for one of of these dodgy ecu's 😭 Interesting vids buddy, I'm a Haldex, Knorr & Wabco Service tech 👍
Thanks for the comment, I'm glad to say we don't change many now, it's always fun trying to work out the meaning of life in a lay-by (I don't miss doing DAF aid 😂)
I wish I did more with the dedicated haldex, Knorr and wabco kit 😎👌
@@TRUCKTECHUK I'm independent, OE software is always nice, at least multi brand gets them rolling. I work alongside all our local main agents and independents. Love sharing skills.
That's good to know and a brilliant attitude to have buddy, sharing is caring 😂 one of the reasons I started this channel was to for people try and level up on their own skills and be more confident doing diagnostics.
I've done a little with JALTEST on the HALDEX side but would really like to get more in-depth with it all.
@@TRUCKTECHUK been using EB+ for 20 years now lol
I remember when this was not a known issue ,,i was sent out on a roadtest let say that was fun as it cut out on the motorway ,about 3 hour later it started and cut out after about 15 mins ..Luckily i have 2 brand new ecus in my toolbox so a lad brought one down ,programmed it ,i then did an very very very long road test with no issues ,then we would get the odd one failing till it turned in to an avalanche ..But like everything the first one is the longest to suss as it was not a known issue at the time...Though it is mounted on the "cold side " of the engine it isn't getting cooled in my opinion and it is too close to the engine ..but that is only my opinion...im amazed you got a new one the following day ,they where like rocking horse shit at one stage
I believe as long as you supply the log file when you escalate the case through support center they will send it next day as I think they hold some back. This was mx-13 also, I think the majority of ECU failures are mx-11.
But you be pretty annoyed as a opperator if you had a a truck break down and the technician decided the symptoms were the same as a ECU failure, bangs a £1000 pounds worth of ECU on and it breaks down again with a wiring fault. I just hope technicians don't guess every time as it was such a common fault
@@TRUCKTECHUK Ah you probably have a stores that are helpful and not a hindrance ..I honestly couldn't say if our failures have been mainly 11 or 13 ....Our last one was a its and we had it couried up from another dealer ...Fitted programmed etc ,then when finished the boss from where ever decided it wasnt the ecu and wanted the old one on..i did explain that he had bought the new one as it was programmed he authorised it via its and we will fit it plus labour ,no surcharge and when he breaks down he has recovery to pay for and he will be at the bottom of a very long Q ...it didn't even make it out the workshop lol...
Great video very helpful, wonder it you can help i have an lf 55 2005which looses its throttle response after having pulled up to a stop very intermittently about ever 150 miles after about an hour it works fine again,its been to Daf lots of times, the only codes are steering hard ware soft ware probem, immobiliser not communicating with engine, noting in the engine ecu or brake ecu. Its had new throttle pedal iv checked the wiring and buttons in the steering wheel, had the vic tested and the engine ecu, I still suspect the engine ecu, I did wonder if the brake switch was sticking but thought it would pull up a plausibility fault and it won't play up while I'm looking at live data, any help would be a great help.
Just had a euro 6 daf.
Once warmed up dash went nuts think it used all its lights.
But truck still ran after checking the usual suspects I remembered this video. Let it all cool down watching live data and using heat gun bam went nuts.
Hey, thanks for the comment 😀 . I'm so happy you remembered the video and used the heat gun 👌.
What's your plan now? Send it for repair or replace it?
@@TRUCKTECHUK just heard back. Ecu is un economical to repair.
Well, whatever you do, make sure the ecu comes back to you as I can bet you a NEW ECU they will fix it and sell it on otherwise!
you want the customer parameters and injector codes too from the old ecu before fitting the new one 😉.
If you want a competitive price on a NEW genuine daf ecu, use this form trucktechuk.com/contact
@TRUCK TECH UK gonna be an expensive exercise. Old ecu had no comms so can't get old files out.... need to get daf aid out to it.
But believe they sending it back anyway.
@spockil your be good for injector codes if you use davie 4 as it will be able to recover them, and if you don't have complicated customer pto parameters, you should be okay without the old ecu.
Let me know if you're stuck 👌
I have trouble with lf euro 6 engine protection is up in red ... it won't allow connection to immobiliser with texa or jaltest ..
Cheers
Hey thanks for the comment 😃👌. I hope it helped you in some way 😊😎
@@TRUCKTECHUK I deal with heavy plant and forklifts, cherry pickers ect, but diagnosis on our euro 6 forklifts is pretty much the same, thanks again
I watched your video and I know these ECMs are hard to get inside. You seem to have a great chemical to release the glue they used. Can you let me know what to use and how you did it.
This repair was carried out by a 3rd party but toluene, acetone & benzene can be used as a solvent. These solvents must also be used under a high temperature condition while working on the joint in order to separate the cases.
If you look at ECU separation on TH-cam you will see the process of other ECU remanufactures sperating the housings
On the euro 5 engines I usually would take a 7/8 wrench and just lightly tap the cone shaped part on the ecu , when the engine shuts off after a tap 99% of the time the ecu is the issue
Thanks for the reply!
I can't say I've ever had a euro 5 engine ECU fail on me yet but then the amount of euro 5 vehicles I work on might be 1 a month possibly
Hello, do you know why the CVV starts rotating during a module update? Thanks
Hey thanks for the comment I believe it's to do with communication with the diagnostic software as your are writing new files to the ECU hence the loss of DIP and the headlights coming on
Hi got all them faults on mine and pci making a noise but won't start took the pci off and sent away for repair but they said they was unable to communicate with the pci and said not to put back on any way of getting in to communicate with it
Thanks for the comment. Does it start when the vehicle has cooled down or is it constantly like this?
Have you thought about sending it to another ecu repair shop?
Possible that ecu clone by using dimsport new trasdata?
Thanks for the comment.
I'd love to try and clone a pci ecu as programing is such a pain without dealer tools
Hi mate . Just need to ask for your help . 2016 Daf 510 . Egr valve showing a mechanical fault . Jaltest not great on dafs . Do egr valves give much issues ?
Hey buddy thanks for the comment. I don't see alot of faults mechanically with EGR valves...I'd have a video on one if I did 😂🙈.
BUT if the link arm isn't bent and it moves through its full range of motion smoothly, your going to need to either swap it out to see if the fault clears or cough up the 2 grand for a new one unfortunately.
@@TRUCKTECHUK thank you very much for that advice pal . Ill let you know how i get on . 👌👌
What diagnostic adapter are you using bro ?
Thanks for the comment buddy 😎. The adaptor or VCI is a Bosch MTS 6517. But branded as PACCAR
What year did the ecu's stop faulting ie.. from what year is it safe to buy a daf?
It's never safe to buy a DAF lol. They did improve the design and if it's had a new ECU recently it will be the improved design. Daf now suggests changing the ECU rubbers every 3 years to prevent them from going hard and increasing vibration.
I'd be looking for a DAF built at the end of 2022 NOT NGD BUT before the camshaft issues of 2018-2019 on mx-13
Hope this helps
My ECU die today.. Need to replace it 😢😢😢😢
Hi brothers
Fascinating...What Programming software and device do you use?
This is PACCARS official software for the DAF products called Davie 4
can you explain pls how open it ? the glue is too strong
Hi thanks for the comment. Yes the glue needs heating up while you use special ecu tools to separate the casing. You also need to clamp it to a workbench to keep the plugs in place while separating it. It's a very involved job.
@@TRUCKTECHUK can you pleaase tell what tool need to be use ? i ve heating, try to open , no succes , i broke part of shield

I'd be using these and some big G clamps to keep it to the workbench
