2015 328d F31 'Journal'
Figured I would put together a thread to log the progress of my 2015 F31 328d xDrive. I purchased this car last year to use as my pavement pounder for work. This car will see 35-40k miles annually for work and having the ability to drive onto production and construction sites (within reason) is a necessity. My previous BMW's (E46's and E30's) have typically been rather low to the ground and always manual, so this moderate height automatic car is a definite change for me. That being said, I've really enjoyed the car with only a few gripes.
July 2019: Car purchased through CarMax and transferred from one of their locations in CA. Car had ~40k miles on it and checked out well mechanically, however I could certainly tell there was an issue with the transfer case. Car Specs: 2015 328d xDrive Sports Wagon Alpine White exterior Black Dakota Leather interior M Sport package Lighting package Technology package Comfort Access package M Performance Side sill decals (removed 8/2019) Cold Weather package Transfer case replaced and AC freezing issues fixed shortly after purchase. Once the TC was replaced, I utilized Enabled method with Loctite and a rubber guibo to potentially quell the need for another replacement after ~40k miles. Maintenance Schedule: Oil change with Mahle filter and Liqui-Moly 5w30 – 8k miles Differential oil changes with Klubersynth GE 4 75w90 – 40k miles Mahle engine and cabin air filters – 30k miles Mahle fuel filter – 30k miles Transmission pan and ZF fluid replacement – 60k miles Added Thule Aeroblade roofrack and Rockymounts fork mount trays to transport my bikes to Western NC and back. Tires were worn on 400m wheels, so took the opportunity to replace with 351m wheels with 245/40/19 Pirelli Cinturato RF’s. As I spend a lot of time in very remote areas, not having a spare tire is not an option. However, the poor ride quality of these tires has convinced me to switch to go-flat Michelin’s and carry a plug kit for my next setup. Max Last edited by clemsonf31; 09-03-2020 at 01:37 PM.. |

Next up was suspension; decided to go with Koni Active Sport red dampers paired with Eibach Pro Kit springs coupled with F80 bump stops. These get rid of the xDrive ‘reverse rake’ while still keeping the car streetable and a moderate height. Tried to get an accurate before and after with the same background
During this time, the turbo lag of the N47 was wearing on me. My last vehicle was a supercharged 2nd gen Tacoma that felt much quicker than my F31. KermaTDI tuning provided me with a Stage 1 tune that really improved overall drivability and behavior of the car. I would recommend the Kerma tune to anyone that wants the best performance without compromising emissions or reliability. Interior upgrades: Bimmertech MMI Wireless CarPlay interface Carbon fiber/alcantara wrapped interior trim LCI climate control surround Alcantara wrapped MSport wheel by CobyWheel Weathertech floormats (a must) 20% black ceramic tint Max Last edited by clemsonf31; 09-03-2020 at 01:38 PM.. |

As this car came from CA, it was outfitted with a front license plate that was installed by a construction worker. The plate fasteners were drilled directly through the poly bumper cover and into the bumper support, 6 holes in total… Sourced another MSport bumper with no side reflectors and added a M Performance style lip.
Most recently, the car was due for a brake pad and rotor replacement. As this is simply a daily driver and not going to see any track time or auto-x’s, the MPerformance brake setup couldn’t be justified. I sourced a 335i brake setup from a member that advertised the calipers to have been newly painted with G2 caliper paint. Although I intended to remove this paint anyways, the quality of the paint job was extremely poor. I’ve always liked the orange MPerformance color against white, so I stripped the calipers, had them sandblasted and powder coated with a powder color of my choice (purchased from powderbythepound.com). Utilized Zimmerman blank rotors and Hawk pads while also doing a full caliper rebuild. Max Last edited by clemsonf31; 09-05-2020 at 01:09 PM.. |

Really nice. I did the 340/330 conversion a few weeks ago as well. Lovely work on the powder coat and color choice.
Mine was a Cali car as well so I know what you mean about the holes. Had mine shaved and resprayed then tinted the reflectors. Wish I could have gotten the euro bumper, it looks great. How’s the KermaTDI when you are leaving a stop sign and turning right? Like joining traffic. That’s where the lag to me is excessive To the point of being dangerous.

Another suggestion that I tried before the tune was ‘resetting’ the throttle limits. I can’t remember specifically how it was done but I found it on these forums. It’s done with the car off and results in minimal improvements in throttle ‘response’ Max |

Haven't updated the thread in a while. I've been working through HPFP issues and have replaced the injectors, pressure sensors, quantity control valve, LP supply pump and the HPFP. All of those issues seem to be rectified. Next up is thrust arms as the passengers side is beginning to leak oil.
Additionally, my annual wheel change landed me with some APEX ARC-8's in 19x9 et28 with 245/40/19 General GMAX AS-05 tires. As with my EC-7's, this was against the APEX recommendations but as I drive on changing surfaces, a 35 series tire doesn't cut it. There is no interference or rubbing at all with these and they look good. Although they are not as light as the EC-7's, still lighter than most of the OEM BMW wheels. EC-7's are also for sale, they are like new! https://f30.bimmerpost.com/forums/sh....php?t=1825094 Max |

Decided to dump the muffler and have a dual tip welded on. Purchased an OEM rear diffuser from a 328i to accommodate the new tips. Sound is marginally louder without the muffler, I would say it’s hardly noticeable at all.

Such a great F31 after all the modifications. Eibach Pro springs with Koni Special Active shocks was an excellent decision based on how the wheel fills the fender space.

If you were going to leave the muffler on but go for the dual tips with that diffuser what would be better, a Y version or one that's straight and the 2nd comes off to the side.
