In this video I show hot to diagnose no boost trouble codes on this N63 BMW 550 V8. The steps can be used with other set ups and can verify systems operations.
Thanks for the post Sadel. Another great video. I love the fact that the scanner shows the "ghost" values. I tell my students all the time that you cannot fully trust what the scanner is telling you because of substituted values, interpreted values or some programming strategy that we as techs are not always privy too or have the resources to know what the module is going to do in certain situations. Top notch as always
Yes, it can be difficult or frustrating at times when you are stuck looking at the scan data to only realize it was substituted values. That's part of the reason of why on these I just use the scope and go straight to the source. Thank you for watching and keep those students on their toes! 👍
Hey sadel, nice vids. Strange how both sensors failed the same amount away from 1 bar. Crazy. I did like the way you proved it out. Definitely invaluable content on the process u showed. Very solid
Thank you Mathew, Yes I was surprised on how both were reading the same incorrect value, I do think though at one point the engine was replaced and maybe some faulty sensors were installed then without knowing. But was clear as day once known goods were installed. Thank you for watching
Great video, Sadel. Thank you for the detailed process of your diag on this car. When you eventually hang up the wrenches, you can open ‘Sadel’s Scope School’.
Hey D-Tech Engineering, thank you for the great video! I just found your channel and I’m blown away at your diagnostic abilities and your knowledge! Just a quick question about the video. I saw that you hooked your PICO scope up to booth charge pressure sensor but you converted the voltage to an psi reading in the scope? Did you use the math channels and a voltage to psi chart for the charge pressure sensor or how did you do,that? Thank you for your great content! Greetings Tom
Hey Tom, the way I did it was by using the create custom probe settings in pico software, within that you can create a table of certain voltages equaling certain units (like psi). As far as the sensor scaling, I got that from BMW service information literature where it actually states the voltage/psi for it. In this case it is 0.5v=3psi up to 4.5v=36psi. So I take that scaling, create a custom probe and then I just use that when testing these sensors. Hope that makes sense
most likely not, I at least have not experienced that even when I have had cars with bad turbos. At that point it would just idle as a naturally aspirated engine
Where are you located?? Damn i wish i could take younmy m6!! My m6 does not have power it does not peel out when steping on it!! And the rpms move slow when stepping on it and it mever hits the rev limter
So what was basically what was wrong with this car in plain English 😂. I got a n55 engine my dads car it’s misfiring and has a lack of boost and when accelerating we hear a whining noise could this be the turbo? We have codes for low charge pressure. I visually checked around at all charge pipes and such and didn’t see anything out of the ordinary
this one had boost sensors that were not reading correctly. I would check for system leaks on yours and see if that leads you anywhere first before getting too deep
Only 30+ views???? Yeah ppl really sleeping on you bro! Some of the best content and tips on this channel! Thanks for taking the time to share!
Thank you for the support and glad you're picking up good info !

You can put your money on it
This guy will not just throw parts on car and pray car will be fixed.
Great video 👍🏻

Another logical, methodical approach Sadel.
I sent you an email about your recent video too when/if ever you get to it 😉
Great diagnostic approached 👏👏
thank you very much for detailed diagnos 🎉
thank you for watching
Umverglaublich!
You are guru!

Nice Video. Very informative 💪🏼

Can i bad turbo cause a misfire at idle? Great diag
most likely not, I at least have not experienced that even when I have had cars with bad turbos. At that point it would just idle as a naturally aspirated engine
Muy bueno info sadel

Would you buy this exact one?
Is this a good car to buy?
Damm man I wish u were in michigan I can't find a mechanic out here worth their weight in shit on these cars
I hear that often, your more than welcome to ship it over, I have had people bring me cars to diagnose from out of state.
@DTEAuto OK that's cool I'll have to keep that in mind when I get my tax return

@@DTEAuto would you be able to diagnose it without a scope
so what were the sensors he changed?
The boost sensors that are installed in the intercoolers
@@DTEAuto ahhh those pesky boost solenoids. Running into a similar issue. Your breakdown is amazing.
