Codes on my 2009 X5 35D

[Waykooljr]

Okay, an update for those who are interested.
At 91K miles I did complete tune and delete on my 2009 X5 35D and while in there, I replaced every sensor and pressure converter, all vac tubing, vacuum plenum charge air pipe and intercooler gaskets, both EGR deletes, CBU removal from intake manifold (my god what a gunked up mess) new intake gaskets, AFE high flow air filter, race throttle body, Buzzken exhaust, SCR delete ect and installed JR 2.0 race tune. After I tuned it the last code I had was a 3F01 code. I had replaced the MAP sensor when I did the CBU on the intake manifold. With the JR tuning from AA Rodriquez and new exuast I had so much boost it kept blowing off the charge air pipe. Due to the fact I kept tripping the MAP sensor from the extra boost, the new sensor failed. After conferring with Aaron at Tune My Euro, he suggested to replace the new MAP sensor due to the repeated failure of the charge air pipe. This fixed the problem. I have installed an ATM charge air pipe and high pressure fittings and this X5 is now a beast!!!! 32+ mpg freeway and 27 city and TONS of power. the 32 mpg are at 70 mph freeway. the car actually runs quieter and is sooooo smooth. I have tuned and built several diesel projects and this one was a little frustrating as I learned about the BMW way of doing things. Contrary to the belief of some I did NOT try to "tune my way out of engine codes" This car is running so well now I am shopping for a 335D for my next project. By the way I can whole heartedly recommend www.tunemyeuro.com for parts and upgrades. I sourced my parts for my build from them for my last two projects and the customer service and after purchase support was better than the majority of online retailers I have dealt with!!
I did the entire delete, tune and rebuild myself, in my own shop every step of the way. If anyone has questions or issues with their delete, tune, and build on this project feel free to message me and I will help as much as I can. I got all the parts out in one piece and did not have to cut up anything, just make the recommended cuts on the exhaust piping. it was challenging but you can do it! Stick to it and you will love the results!!
