- DAF Mx11 bpv faults this week. With amber engine warning and exhaust system malfunction , I needed to get to the bottom of these faults with various BPV issues such as p1052,p101e,p1024,p1025,p1026, u1579 and p1496 it's safe to say it will need a new BPV, so In this video we remove and replace the BPV after diagnosis.

I worked on Dafs for years at a dealer, and tbh really rated them as a truck, this was PR and XE, then the E6 models came along, holy crap! company I worked for recently got rid of 50 mx11 trucks, the workshop was the quietest I had seen it in many years.
Hey thanks for the comment 👍😎 seee I prefer a mx-11 or mx-13 e6 and my-17 to any euro-5 engine. I just find the diagnostics rather backwards 🤷
It's not really a fair comparison, with all manufacturers the Euro 5 engines were much simpeler than the Euro 6 ones. In fact I'd say that Daf did comparatively well with their earlier 2013-2016 Euro 6 trucks. The 2017-2021 ones are not as good I'd say.
I looked at one of these the other day. Non active fault code for BPV not reaching position. Looks worn on spindle like that one. Vehicle requesting a regen, cant even get it anywhere near due to exhaust temperatures being so low, like 140⁰c. No leaks on exhaust anywhere. Hoping to see the BPV flap not fully closing when it gets removed! 🤞 Over 3k in parts!
Great insight these videos mate! 👍
Hey buddy. Yes it's crazy that people keep buying BPV'S just to fix this shaft issue. I've got my hands on a used one now so I'm going to set up a rebuild service for customers I think once I've got my parts from America for this service 😎
@@TRUCKTECHUK I'm sure there would be a decent call for repair on these! Could be a nice little side earner! 😂 How they justify the price of new is beyond me! Cheers Russell 👍
@danielbulmer5863 I need to make up my mind about which was to go with things business wise. I've got more PCBs coming for the turbos too. I could be in an office and just do website sales, turbo and BPV repairs all day every day 😂
Nice to see a fellow halfords screwdriver connoisseur
Thnaks for the commnet! 👍 Ha ha ha you can't go wrong with 12 quid for a full set! I remember when I used to buy snap-on ones for £100 😅😅😅😅😅. I don't need to go into a rage now when I lose one 🫣.
Just come across you on tiktok and had to subscribe, loving the format, fantastic knowledge and fun to watch. From a fellow master tech great work!
Hey thanks for the comment buddy 👌😎. Nice to see you have come across from tiktok ☺️. Videos are more in-depth here...hope you enjoy it 👍
Evening I plugged it in, and the faults cleared on their own I carried out a force region
But i had to operate the old bpv valve as and when the new one moved to get it to regen temp it took a while but was fine and is back on the road thanks again
I'm glad you got it sorted, the cleared off the dash but not out the ecu. They would of gone from active to stored.
with it being euro 6 I'm sure by the time it requires another one, it won't be your problem
Another great video, your timing spot on for this one, as had a code for BPV on a 2016 MX11 yesterday, which will be next weeks mission 😊😊😊
Thanks for the comment buddy 😎👌.glad it was good timing for you 👍, make your life easier and buy this new style clamp for getting it back on.......no longer do you need 8 hands 🤣
@@TRUCKTECHUK Thanks for heads up mate 👍👍👍
cheers bud very use full
Hey nice to hear from you again ☺️. Thank you for your comment as always 👌😎
Quick and easy diagnose but SOO MUCH work to replace that damn BPV!
Nice one 👍🏻I’ve got 2 at my garage to change if they stump up the £3500 for each BPV thanks for posting this 👍🏻🏴
Thanks for the comment. If you want a better price on the BPV'S you can always contact me here trucktechuk.com/contact
Ok thanks I’ll let my manager know and thanks again for posting these helpful videos 👍🏻🏴
love it mate
Hey, thanks mick! I'm glad you enjoyed it 😀
Thank you.
Thank you for your comment buddy 😎👌. Glad you enjoyed it 👍
Imagine doing that job in 10years time..... I hope I'll have retired by then! Great content.
Hey Darren thanks for the comment 👌. The jobs only getting more technical, you should see the electric vehicle vehicles coming through now!
@@TRUCKTECHUK I will be retired and no i do not want to see the Electric trucks ,i don't even want to see XDs XGs lol
@@norb0254 by the the you have finished these camshaft recalls your be past retirement age 🤣🤣🤣👌
@@TRUCKTECHUK On a LF head gasket frenzy at the moment .Thought i a quick gearbox turn around job on a AS lite ,,,Yeah bulkrings for 1st 2nd ,part number on the box is what i asked for ,pity the parts inside weren't lol..So packaged wrong to part number ..So a wait till they sort it out lol
Hi. Could you help with one information please? On various webpages from Netherlands it says that ref 1960472 can be replaced with 2256384. Is that true? Thanks for the high quality content.
Thanks for the reply I’m hoping it will work as we have a new lorry coming next week and that’s going as part ex I’m just hoping is not like the Isuzu and uses that to get it hot I’ll make sure it’s red hot and I’ll let you no thanks again
Let me know how you get on, and don't forget to clear the faults out afterwards as thats something we would look at on end of line lease or trade-in inspections.
You did well changing a BPV in a tipper chassis,,,,Ah the E-fan that likes to throw up low fuel pressure faults lol....Just to keep us on our toes
Hi buddy, sorry for the late reply! ahh yes, the good old fashioned struggle around a tipper chassis - my favourite! I can't believe how easy it was to take off to be honest, luck must have been on my side!
I suppose without those pesky faults flagging up we'd be without a job, however I'm not that grateful at the time haha!
Have you been up to much this week?
@@TRUCKTECHUK LF Head gaskets.and a LF manual.aa lite parts wrong to number .and just as I have hols I am ill lol
I god a active P1496 fault ON and 9 records of P1710/P1711 about nox sensor before CAT. In this situation may be the nox sensor that trigger the P1496 fault?
👏👏
Holding up the BPV and getting that clamp on 😅😂 preach!
Thanks for the comment 😎. You know that's a separate qualification on its own 🤣🤣🤣🤣.
If youre lucky your Finger fits into the hole where the nox sensor is seated. Put the clamp arround the turbo, lift the bpv in there, hold it with your finger and get the clamp arround. The clamp doesnt need to be tightend to hold the bpv so you can use your lifting finger to put in that T-Bolt
Today on CF 😂
@truck tech Uk hi great video got a Daf cf 2015 18 ton with a bpv actuator fault if I connected a new part would it allow me to do a regen as can’t get it to regen with a active fault
Thank you for the comment👌. Connecting the new BPV should let it do a regeneration as its looking for the position that your old one won't be reaching. But what will that do to the actual regeneration process? I don't know, as I've never just plugged one in and carried out a regeneration. Fingers crossed, I suppose 🙈
Enjoy any coolant tubing related updates along the way.
Hi what diagnostic do u use great work
Hey Kyle thanks for the comment. I use to use Davie for alot of things but now not so much as you don't need it to work on these dafs
Hi. As a driver it’s great watching and learning the ins and outs of the faults and the rectification process to get rid of those bloody P-dings!!! I’ve recently had my BPV changed on a 16 plate MX11, would this alter the performance of the engine brake in any way? I don’t feel as if mine is working as efficiently compared to the old one. Truck is automatic and changes down but doesn’t seem to have the retardation of old.
Thanks for reading and awesome videos.
Hey thanks for the comment! the fact you understand the systems is always a bonus from a technician's point of view as the more information on an issue you can give a technican the better when you want it fixed!
As for your BPV issue, the part itself is what is called a smart actuator and processes all its own faults and positional data.
If the engine is requesting a position or pressure for the turbo.....the motor will move it to that position....say 3 per cent for regeneration. If its unable to reach the desired position you will get a DTC just like in this video. This is the "requested" and "actual position" I'd be looking at in monitoring data with a diagnostic tool
So if its not performing correctly you should have an error.
Hi, no faults since new BPV fitted, also had the fuel cut off air valve replaced and a couple of NOX sensors, personally I think the BPV has been faulty for a few months as been having faults for months so maybe I was spoiled as it was not working properly. Has now started doing more regular re-gens than before as well. Maybe a bit coked up down the system? Fitter saying dpf is clean going by his diagnostics. Truck felt down on power too but I think it’s starting to come back to me. Will see how things go. Cheers.
Hi Buddy, I love your videos they are so much help, I have got a 2020 DAF CF with a BPV Internal error code P1020 the bearing had collapsed on it so I have just changed it and it is still coming up with P1020 internal error, could this be something to do with the E-FAN? If so how could I rectify it? I’ve checked all the fuses and nothing. Also in the comments you said you are going to start fixing the bearings on the BPV’s have you started that yet? Thank you.
Hey Tom. I'm glad you enjoyed the videos. If you have an internal error the only fix is replacement unfortunately as I've been unable to identify the actuator supplier. I've got a BPV here with the same faults. Internal fault and positional error. I have a kit here that needs to go into production for the shaft and with the welding required it will be a service exchange unit. But as for the internal error, it is just that... an error that is internal to the actuator which seems to be captive to PACCAR unfortunately
Hope this helps
@@TRUCKTECHUK thank you my friend, in the end I sorted it, I made up some wires and put two trucks side-by-side I plugged one truck into the other truck reset the codes and then plugged the BPV back in, and it worked, I’ve been sending my BPV’s to Poland and a guy there refurbishes them and changes any components in the actuator, it costs about £1000 with postage and packaging.
That's crazy that you needed to plug it into another truck! I wonder what it needs to see for that to make it work 🤔 you would think clearing the codes would do it 🤷
I will look into the actuator when I get more time, fingers crossed I can get a service sorted for people 😎
Does the bpv need to be programmed after replacement? I jpro, Davie is expensive !
Hi Raymond 👋 thanks for the comment 😎.The BPV does not require any programming after fitment. I will add that to my article actually for people in the future 👌
blog.trucktechuk.com/2022/12/the-bpv-actuator-mystery-revealed.html
Also what test leads were you using for your diagnosis
Unfortunately, they were dealer-specific leads which come with a silly price tag but I'm working on a project that will plug into all the basic daf components and measure the functions for you 😉
@@TRUCKTECHUK what are the test leads called ?
@Raymond Romero I have no idea off the top of my head other than like T-06 l. Closest thing I can find for general sale to the public is ebay.us/iv6F82
Have you run into P1021 BPV actuator CAN communication error? im stuck there
Hey thanks for the comment 👌.
You need to check for power and ground on the bpv and check for can comunication. If you have them (you have 4wires to check like in the video) your going to need a new BPV
BPV was Replace.
@@pantherelio do you have any other errors in the PCI ECU?
What about fault suggesting bpv erratic?
What is the actual fault code or description buddy?
Evening don’t no how else to message you have you ever had a Daf Lf 70 plate 18 ton with the bigger automatic zf astronic box slave cylinder on the n/s middle burn out has a pto on it but it’s up in the middle slightly damp it’s basically locked solid lorry does run but hunts oil smells burnt out has oil in it not to the level bung as got hot do the oil pump go wrong inside thanks Ben

How bpv works?
Thanks for the comment and watching the video.
If you want more information just like the bpv, I've a blog on my website that goes into more detail on systems and components which for the BPV you can find here: blog.trucktechuk.com/2022/12/the-bpv-actuator-mystery-revealed.html
The bpv back pressure valve or egr throttle as it’s called in non daf speak is ther to promote higher exhaust gas recirculating rates
@@Gearhead90 .... and used to increase exhaust gas temperatures during regeneration modes, both mobile and parked.
Hello. I have such a problem DAF 106 440 starts and stalls, error P1026 P1020 P1021 P1022 is the cause of BPV.
Hey thanks for the comment. I'd be fitting another BPV with them fault codes
Thanks a lot. This is why the engine won't start.
the engine starts and after 5 seconds it stalls and the gas pedal does not work
Disconnect the bpv electrically and try running the vehicle.
@@TRUCKTECHUK OK. I'll try tomorrow and write to you. thanks again
Lost your number
Ya crack me up you do fella it’s bloody crap when ya apprentice goes away there so inconsiderate it’s all me me me me me 😭
Thanks for the comment ☺️☺️ I'm lost without a apprentice, I not only do I have to do all the diagnostic work, I have to tip cabs too now 🙈🤯
Wish I’d of known they’d changed the clamp style I’ve been reusing the old ones trying to get the bastard nut back onto the threads 🫠🫠🫠
Hey thanks for the comment 👌 I didn't know either till I put the part number in and it had superceded 😃 so much easier 😎😎👌
@@TRUCKTECHUK hi mate don’t suppose you could get the partnumber you used for the clamp. Gone on our rmi and looked at supercession and clamp I’ve got still uses a nut
@@joshuapeaker just had a look at a mx-13 I've got in now with failure to reach position and checked the part numbers for the camps for you. Clamp diameter=122mm old number: 1909938 new number:1979194. I've checked our stock and that new clamp deffo slips over the top and tightens not pushes through with the little nut like the old one.
Hope that helps, let me know about the number you have
@@TRUCKTECHUK just finished doing mx11 bpv about hour and half ago. The numbers are different it seems between the 11 and 13. I had 2121051, however clamps are same size 122mm like you say just has different bolt clamping.
I have faults for bpv
1 being out of calibration
2 for internal error I’m presuming it will be this at fault, have it to do on a coach 🫠
What about fault suggesting bpv erratic?
Hi have you got the full fault code description such as data erratic, intermittent or inccorect?
