Awesome Video mate, I had a p0299 under boost fault code , followed your video and it was also the transducer on my van that was faulty , thanks for posting the video 😊
@@kevcampbell3365 thankyou, glad it helped
Glad I found this, local garage has had my E220 in 3 times for low boost, black smoke & EML when giving it the full beans. DPF has been 'modified' but fault persisting. Bought my own code reader & this is the code I get. I vac-tested the large actuator capsule today, that's holding pressure. I can't see the solenoid from up top, & I'm not mobile enough to get underneath but certain I can hear air escaping where that filter is located.
Hey man did you fix the problem?.. ive got the same issue..
Great video. This was easy. Guess what though? I changed this part and then realised the vacuum hose that attaches to the wastegate wasn't attached to the wastegate - So advice to others is to check the hose is actually still attached to the wastegate...They are only push on so can snag and come loose.
Thanks to this video, I repaired my sprinter .
👍merci
Good to hear, thanks
I too am doing some research on this, Ive got exactly the same fault as in this video
i have not long paid a garage I know to replace my twin turbo with a brand new/recon warranty unit + manifold studs & gasket + rocker cover gasket & 4 injectors. I now get P226300 but in really weird situations.
Start up and drive off, do nearly 100 miles, up hill, down hill, long up hills, long down hills and no bother (all variations of high boost/high load)
Yet, I then park up for a day, get back in it again, do the same thing again but in reverse and within 15 minutes, high boost & high load, EML on, limp
mode and fuel burn is rediculous.
I end up pulling over, turn it off, turn it on again and its ok for the rest of the 60-70 mile return trip up & down hill on high boost & high load. Driving with limp
mode as per fuel burn, i have to let it reset itself to return the van to a semi economical state.
I think the garage replaced with aftermarket solenoids so im going to get them genuine units and try again.
I think they found this video tbh as they also said they did some research and did a vac test test and didnt detect any leaks.
It might also be worth having the intake system smoke tested to make sure the inlet manifold isn't leaking.
Good shout - i built my own smoke tester when i had strange faults with my e46, this dis show up a very small leak.
ill give this a go myself - thanks 👍
Nk you. Greeting from Serbia
@@CyleFZ660 Hello from England
Thank you same problem on mine
Glad I could help
Thankyou great vid same code
No problem 👍
I had this same issue for a while and the garage couldn’t fix it. After about 6 months it was due for an MOT and it failed due to an oil leak. The oil filler neck connection at the engine was faulty and loose causing the oil leak which I think was also causing a vacuum leak in the engine. The filler neck was repaired and the fault code never returned (I would go into limp mode pretty regularly). Just an idea for those who are having trouble resolving this.
Thanks for sharing, modern engines don't like any kind of air leaks.
Hello
Thanks for this helpful video, it is slowly putting me in the right direction I think.
My pressure does not hold even when you clamp off that line as you have done in this. I pump direct into the black plastic distributor, and instantly pressure is lost.
Any ideas? Thank you
If all the lines out of the accumulator are blocked off it should hold pressure, if it doesn't that would indicate the accumulator has a leak.
@@MJF85 when I clamp off the air filter now, it holds pressure. If I integrate it, I get no pressure.
@@MJF85 So in this video where you're testing the pressure, the air filter is incorporated into the vacuum, and is holding pressure?
At the moment I'm still leaking. If I clamp off the air filter, it holds pressure. I don't understand. Would be grateful for any help.
(Transducers changed, one hose replaced, new air filter, fitting a new actuator in the morning as the arm does not move when I pump air into the back).
Thank you
Thanks, video was very helpful.
Glad to hear it!
I have been chasing this for well over a year now I’ve just picked up the part will try it now hopefully this solves my engine management light problem thanks for the video Will keep you updated
I have the same engine in 2015 , am in mission of hunting down p02a7 for months now , I wonder if you come across this kind of code , it does say cylinder4 fuel trim at min , I swapped injector3 with injector4 still does say p02a7 every now and then , the strange thing is the code will not come straight away though , after sometimes will show up but as soon as you delete code you can drive with now issue at all , but code randomly will pop back in , its really had given me a headache , injector 3 was refurbished injector but it was on this van for over 2years now , when I replaced it back then , I didn't do any coding but it was working perfect without any coding and no engine check light back then ! , I tested the vacuum following your method in this video it does hold vacuum very well with no issue so am pretty sure no vacuum leaks , I have taken intake manifold last month to find out about that bolt snapping on these engines , couldn't find any problem , changed o2 sensor with no luck , but am still suspecting the o2 sensor because when the engine is running if you disconnect the o2 sensor no code will be come on , as if its already connected !!! its strange to me , your opinion will be appreciated it .. Thanks in advance mate
I have a similar issue I replaced turbo p2263 low boost I noticed that the van would judder just before the eml light came on. Now with new turbo I get juddering especially noticeable going up hill but no eml no low boost etc what I have noticed is the actuator moving up and down when on idle and was wondering if the vacuum pipe or solenoid was at fault have you experienced anything like this
Hi..Thanks for the video!can you tell me please if you have the ignition on when you do the test or ignition off?when is on is not hold the pressure is leaking from the filter.
Thank you in advance
I have error "P2263'22 - The boost pressure deviates from the specific value. The signal amplitude is greater than maximum amplitude."
Did you have same error code? Or was it under boosted?
Thanks so much for this video, I have a c class with same engine. Is it not possible to use an air foot pump to do the same job as the Mityvac?? Thanks
It could work but the system is designed for vacuum rather than being pressurised, I don't know wether pressure would damage the seals in the solenoids or damage the diaphragm in the actuators.
@@MJF85 Hey thank you so much for prompt reply. Ok fair enough, thanks for your input, didn't think there would be a difference between vacuum and pressure. Appreciate it
Hi, how many of these solenoids are there on the om65 ? i have a c220 cdi with the same code p226300, some times i get a different code that says faulty boost control b is faulty. now i have noticed i have 2 similar solenoids one in front of the engine close to the water pump and the other is tucked under egr and closer to the brake booster. which one of the 2 did you need to change ? the big turbo actuator gets its vacuum from the one under the egr on my car.
Hi.
I have the same issue with my sprinter and feel like its loosing boost was the same issue with yours and black smoke ??
@northgeorge40 Loss pf power and eml on but no smoke. Smoke usually indicates a boost leak or intake air restriction, I'd be checking for air leaks in the intake system.
@MJF85 i faind the red intercooler pipe cracked change that but still not 100% i will carry on checking for leak
Was you getting codes p0299, p2067,p2068,p2263 and p2359 for this fault
@@gino2465 p2263 from memory
thanks for video mine has same problem where did you get pump from cheers

Hi. I changed both the solenoids. And checked all the hoses, no leaks. But when i clamp the hose as you do, the car goes much better, to a point at 90km/h and then limp mode.. the car drives better when the hose i clamped, but the P2263 error is still there.
What can be wrong here?
Thanks in advance.
It's not a good idea to drive it with the hose clamped, it could cause too high boost pressure.
Hard to tell without seeing it and diagnosing, ideally needs a vacuum tester to test everything moves as it should, possibly smoke test to check for leaks.
Vacum tested all the hose and changed both solenoids. Whats the next step?@@MJF85
Whats the next step if all the hose is not leaking? @@MJF85
Thank you sir !
Most welcome!
Anyone know if a faulty vacuum pump could cause low boost faults ? With engine running
Should there be vac pressure going through main hose pipe from vac pump to brake booster/servo ?
Hello ! This faulty turbo solenoid can cause of unburn fuel like black smoke?.. ive got the code P226300
Hi, it could do as the turbo's won't be working properly so they may not make enough boost.
What engine is this , I have a 209cdi with a mysterious fault which is driving me nuts
Om651 2.1 4cylinder twin turbo
Did you have a like a gush off air sound when you took the foot off accelerator peddle
No, just felt lack of power and EML on
@@MJF85 i get this gush off air the odd time taking the foot the peddle and then EML comes on no power lose at all just says dPF level full but dPF fella says there nothing wrong with DPF. At a loos now
Hello I have this same error code, my symptom is when im trying to acclerate harshly when i reach the higher RPMS my power is very sluggish when i try go on hills it takes forever, do you think what you done in this video could be the cause of that? thanks
I would definitely be looking at this yes
@@MJF85 ok mine is also 651 engine I will give this attempt. Can you advise me where you got those clamps from pls sir.
@umairgqureshi2762 I think they're from mac tools.
A cant get my icraft computer same as yours to read ecu got select sprinter bit of a pain
I have a vito 114 cdi with same engine & having low boost issues have replaced both boost solenoids but still the same, i have attached vac gun to the vacuum reservoir same as video even after few pumps there is no vacuum at all
Gauge showing zero pressure
Have tried with vehicle off & running does this indicate i might have a faulty vacuum reservoir ?
Possibly. If the ports of the tanks are fully sealed off it should hold a vacuum. I'd start testing each part for leaks starting at the turbo/wastewater and working back, that way as soon as the system doesn't hold a vacuum you know its the last part you've tested
Hello.
Ive got a problem.
When i revv the engine i hear a whistle noise now if that normal coming from the turbo.?
Also you mention the hose with the filter i saw my filter doesnt connect to anything under... Even tho i see it has a connecter on the other side for a hose.
I have changed mine and still doing it any ideas ?
Did you use a vacuum gauge to diagnose it? Theres another one of these valves on the front of the engine for the other turbo.

My turbo was making a light metallic rattle sound when the turbo would kick in, it would also sound deeper and grunty now its in limp mode any ideas what this could be?
So I took this part out can you please tell me how I know if it works or not ?
It should hold vacuum on the inlet port, there are 3 ports, an inlet, outlet and vent, the inlet should be closed when turned off/disconnected from the electrics. Ideally you need a mityvac to test it.
