2011-2012 BMW 750i xDrive I N63 Engine Misfire Under Load Repair and Test Drive

[@willdean9327]

You are not suppose to use anti sieze on plugs

[@middlecovemotors2474]

I know right 🤣 I wouldn't want to be the next guy trying to take them out.

[@edwardyeargan15]

Thanks your video gave me the information I needed without hearing someone’s life story it answered all of my questions to repair my car thanks you. Ed Tennessee

[@AbilayKu]

Hi, do you have any diagrams of engine connection/wiring? I can't find anything on google...

[@gnar-ninja]

great video. where do you reside and do you provide 750i services for the public?

[@maichelroshdy7959]

I had the same exact symptoms. Replaced everything. Nothing worked. The solution was NEVER place car iin comfort plus or eco. Apparently if the battery sensor is bad it causes insufficent volatage in this fuel efficient modes. I placed car always in comfort mode and problem solved.

[@mexicanamericansinthedenve6768]

Where is the map sensor located in his vehicle? I seen that you located the mass airflow sensor. But I am trying to locate the map. Sensors?

Do not use anti-seize on BMW motors. Eventually, you will regret it after multiple wrong torque and thread damage. Also, do not apply the grease to the coil boots, apply the grease to only the ceramic of each plug to avoid grease possibly getting on the metal tips of plugs upon insertion. If you're still getting misfires after coils, plugs, and sensor replacements, and vacuum/pcv hose system replacement - then your intake hose orange seal at the turbo inlet point is leaking severely and you need to replace the orange seals. And if you still get misfires or limp mode after this, then replace your diverter valves and if this doesn't fix it, then replace the turbos.

And if that doesn't fix it, replace the car. 👍

[@edwardyeargan15]

Where did you buy the socket?

[@armandoduldulao2595]

i have a 2012 bmw 750 li and it shows misfire cylinder 4&5, i replaced plugs and coils and still have the same problem, any idea

[@TBlopp]

It’s Your Injectors

[@egy1507]

Check the fuel injectors and the seals

[@djmystery7235]

I’m getting misfire under load all on bank 2 misfire codes for cylinders 5,6,7 and 8 I think an injector might be leaking or fuel pressure is bleeding off for whatever reason, if you leave the car for 5 minutes it’s a hard start (extended crank 10-15 seconds) but if you turn it off and back on quickly it starts right up. I’m gonna test fuel pressure than swap injectors from one side to the other and see if the problem goes to the other bank. If not maybe throw a fuel filter and pump at it? Idk

[@maichelroshdy7959]

Did you find the solution. Exact same for me.

[@tomasnavone5461]

Did you solve it? Same problem on mine

[@quirino18]

how did you determine it was 7? was there a code? my its same model, same engine etc same thing happens to me under load i get no Code dough i know you can look at the Plugs and determine by Deposit you see on Plug however how accurate would that Be?

[@BA-ue8lh]

You can get an obd2 code reader online. There are a few bmw specific; like anything, you get what you pay for. Good luck.

[@quirino18]
