My fiance' ran my 525i hot and it caused SO many issues and when I finally finished and I just knew it was perfect - weak crank, muddy sounding - no start.. I've been 2 weeks researching WTF could have gone wrong and I'm the dummy who mixed up the eval and solenoid wires.. Thanks for posting this, you fkn rock!!
Good to see you still here bro 👊🏻 haven’t seen you comment for along time. You know me bro I’m straight BMW till I die a lot of them will jump ship because they got scared of the other chassis and ran off as they don’t know how To fix or diagnose them because there is no videos to follow and they NEED other videos to follow or they can’t do it they can’t diagnose a car with a scan tool as they ain’t experienced like that. Nothing is out of my depth just wait till I get moving with the electric cars on here 😁 I can’t wait to get my I8.
Great video high quality video and well explained without no slow hesitation thx a million you my friend are a life saver and I just suscribed because I love all of your videos need more like ya!💥💯🔥👍
Big fan of your videos. After i got my 328i you were the only one that made sense. I hope im just beign blind, but i replaced my starter and when i push the button the motor turns but just sounds like the starter is spinning.
What’s the squeeze and pull plug which attaches to the bottom of the junction box? It looks like some kind of drain….. Also, is it easier to attach the CCV return pipe to the sump pipe first or to the CCV? Cheers Dean!
hello, good day, you do an excellent job and I am always guided by your videos in the repairs of my bmw, the engine of my bmw e90 n52b25 2.5 has broken down, I would like to know if it is possible to replace it with an n52b30 3.0 engine and what modifications should I make since aesthetically the engine is the same
BMW doctor! I have a weird one that is driving me insane. I bought a 2011 128i N51 engine from a customer that had a failed intake cam adjuster. (Bolt heads sheared off) they sold me the car and I had intentions of replacing the engine but came to my senses that I probably just needed to replace the adjusters and retime the engine as I’ve done that in the past and got these engines running with no internal damage. So I got it all put back together retimed and I went to fire it up but it is a crank no start…. Sounds like it would fire almost like it was hitting on a few coils at times but will not start and run. I had some dme communication codes coming in and I came to the conclusion that I probly had a bad dme from sitting for so long. Got a used one and had it cloned here locally….. same symptoms as before and intermittently I will still have loss of comm with dme if I unplug and plug it back it in it will come back to life on the scan tool but even when it’s saying no comm I can still crank and no start! Any ideas??? Thanks.
Thanks man. Is there anyway you could explain how the reverse system works. It seems like a lot of the e90 has a reverse light problem. I found out about the FRM, the fuse, socket, plug but the wiring confuses me.
Hi dean . I only have i disa ,will i have the same issue with all the wiring plugs etc..i was hopeing having only 1 , i mite not have so much to deal with . Cheers .
I want to know what is INSIDE the junction box? And particularly, I want to know if I can replace the cable going to the MAF by unplugging it inside that junction box?
Hello If I have a no start condition and suspect bad starter or solenoid can I probe the the white solenoid wire with 12 volts to check for crank? Without pulling manifold yo test? Or should I pull plastic cover beside r/h strut tower and go through the connector? Thanks
I did a manifold change and I left out a plug, that I wasn’t sure where I removed it from due to me working on it at night time with minimum lighting , Now the car won’t accelerate, any recommendations?
Afternoon , i have a f20 116i whats boost dont seem to be spooling no rough idle or nothing any more everything around the rest of engine has been done. Mechanic was going to put a forge motersport blowoff valve but didnt know how to assemble it so now i dont know what his misplaced or what not
05 e60 n52 170000 keep getting increased emissions message. sluggish up hills the most of all in your experience fuel pump or would it be injectors? Can you clean injectors on a e60? What are the chances of the catalytic converters going bad on one?
Can I ask what the cable is called from the junction box to the starter solinoid ? I would like to replacve mine when doing the starter. Thank you Bro great videos
Do y’all see how the green connector that goes to his crankshaft position sensor was a little loose? Mine was completely loose and needed a new connector, took over a week to get the connector and now I’m stuck trying to figure out where all these wires go. On my Mazda it is impossible to mix up any wires because they are all different lengths and can only reach the connector in which they plug into
hello mate , i really need your expertise for i com . i dont have enough to buy full set they have cheaper sets without that black orange kinda adaptor which i think its called optical fiber / icom B . so i wanted to see if that thing doesnt do any important job i buy the cheaper version . do you know what does that thingy does on i com ? many thanks mate
I have an 07 328 with no crank/no start.. I took out the solenoids and cleaned them, fully charged my battery and still doesn’t start. I had a misfire code for the coil and after I swapped 2 and 3 to make sure I didn’t get a code and the car still wouldn’t start. Help please.
I changed my boost solenoid 3 times because my 2011 BMW 335i coupe keeps cutting out under full throttle and sometimes it’ll throw me into stupid mode as well. PLEASE HELP HELP HELP. I am sooooo frustrated and overwhelmed with this I had a BMW master tech look at it for months and he couldn’t figure it out!!! Im on MHD Stage 2+ with 93 octane pump gas only with full bolt ons and either a stock turbo or vargas level one or vargas level 2 turbo, the previous owner couldn’t prove to me that he swapped the turbo so I think its stock. GOD HELP ME im so close to ditching this piece of shit and driving it into a wall!!!!
This video deserves a million views!!!

I just like how you keep your videos consistent with being primarily BMWs other so called BMW mechanics jump ship and started working on other brands.
Good to see you still here bro 👊🏻 haven’t seen you comment for along time. You know me bro I’m straight BMW till I die a lot of them will jump ship because they got scared of the other chassis and ran off as they don’t know how
To fix or diagnose them because there is no videos to follow and they NEED other videos to follow or they can’t do it they can’t diagnose a car with a scan tool as they ain’t experienced like that.

a video on x70 n52 engine would be very nice ,Doc .
Great video high quality video and well explained without no slow hesitation thx a million you my friend are a life saver and I just suscribed because I love all of your videos need more like ya!💥💯🔥👍

Excellent information! Super image quality too, Dean thanks bro!
Anyone know what happened to the doctor?
What’s the squeeze and pull plug which attaches to the bottom of the junction box? It looks like some kind of drain…..
Also, is it easier to attach the CCV return pipe to the sump pipe first or to the CCV?
Cheers Dean!
Thanks mate ,for helpful video
Nicely presented and explained mate

Have you considered the n54 intake on the n52 engine
Great info as always dean !
Thanks man. Is there anyway you could explain how the reverse system works. It seems like a lot of the e90 has a reverse light problem. I found out about the FRM, the fuse, socket, plug but the wiring confuses me.
anyway to add the disa connections to the junction box ? need the disa connections for my manifold upgrade on my 318i
Hi dean . I only have i disa ,will i have the same issue with all the wiring plugs etc..i was hopeing having only 1 , i mite not have so much to deal with .
Cheers .
Very helpful essential knowledge. Thank you for posting this one. I'll add that this junction box is very similar to the one on my N54.
Maybe a closer look at each wire going from the position of the box
I want to know what is INSIDE the junction box? And particularly, I want to know if I can replace the cable going to the MAF by unplugging it inside that junction box?
What’s the name of the cord from the junction box to the power for the starter?
whats the part number on the starter wire you called out?
Hello
If I have a no start condition and suspect bad starter or solenoid can I probe the the white solenoid wire with 12 volts to check for crank? Without pulling manifold yo test?
Or should I pull plastic cover beside r/h strut tower and go through the connector?
Thanks
What about the camshaft solenoid/sensor wiring?
I did a manifold change and I left out a plug, that I wasn’t sure where I removed it from due to me working on it at night time with minimum lighting , Now the car won’t accelerate, any recommendations?

Where does the little wire that’s yellow and orange go in a n54 I believe it’s called the pcv
05 e60 n52 170000 keep getting increased emissions message. sluggish up hills the most of all in your experience fuel pump or would it be injectors? Can you clean injectors on a e60? What are the chances of the catalytic converters going bad on one?

Thank you Bro great videos
I have a 2007 BMW 525i would like a diagram of junction box plug-in to in take
Fantastic.... great help

Where is that "secret connector" shown in the "This Plug Changes *EVERYTHING* On Your BMW" video ? Where should it be connected ?
Hi my 2013 740 li xdrive radio, Bluetooth, back up camera stop working what might be the problem?
I have an 07 328 with no crank/no start.. I took out the solenoids and cleaned them, fully charged my battery and still doesn’t start. I had a misfire code for the coil and after I swapped 2 and 3 to make sure I didn’t get a code and the car still wouldn’t start. Help please.
I have the same issue,any advice ?
How is it possible to see the Cruise control coding video? I tried to join but it doesn't work. It says members only.
Check your membership tier level I think that's reserved for the top tier membership levels only.
lololol i just found a mouse nest today in autos class on my 328 in the exact same spot
I think I put my connector’s in the wrong place and it’s now having starting issues
