Hello all, so a couple years ago I purchased my 2011 335D to commute to work because of the amazing fuel mileage, my wife and I completely fell in love with the car! I did my research before purchasing the car and was aware of the dreaded emissions problems but figured ill deal with that day when it comes..... the day has come. Throwing codes P2200, P122C, and P20EE at 120,000 miles and so from what I have read it just keeps getting expensive from here on out. I have been all over this forum reading on other projects and would like someone to help me with mine. Budget is not an issue but I'm also not looking to "build" this car due to it just being a daily/commuter car. I'm somewhat mechanically inclined and if I run into snags, I have a few mates that are savvy mechanics. Taking it to a tune shop is not an option for me so it will be a DIY project. Any guidance would be appreciated!

My suggestions:

Get a set of ramps (for the front), get a decent low profile jack (for the back diff), get some jack stands (for the rear jack points on the sides after you lifted the diff). Get a decent metric socket set, ball end metric hex keys, and an e-torx set. That should cover you tool wise.

Get a CBU cleaning so you start with a clean slate as the EGR will be gone, change the VCG while you're at it.

Tune: Whatever you want / can get. I got the JR 2.5 from Tune My Euro. Great customer service and turnaround time, feel like if there were any issues they would try to help (Andrew actually called me to talk about some questions I had before I pulled the trigger).

EGR / Swirl Flap Delete: TME for the same reasons.

Downpipe: VRSF

SCR: Do the surgery yourself or find an offroad shop to do it for you (cutting / gutting / rewelding) or have them fit a new pipe in.

There is plenty of info on actually doing the work so I'm not going to go into that but hopefully you'll be on the right path. Others might chime in with their experiences / suggestions. Good luck on your project...

Agree with everything Wilamette says, but with a qualification: Little about it is easy, trivial, inexpensive OR straightforward. I second the vote for Andrew. Don't know if he's still doing the work himself, but he took good care of me. If you can get it to Atlanta, that would be my recommendation. I'd make another trip myself, just to get turbos installed, nowadays...

I have owned my MSport since 2013 bought from a dealer as a CPO and it looks and drives like the day I purchased it. It's a great car with over 40 mpg on highway, but definitely recommend you delete EGR, EGR cooler, DPF, gut SCR, tune and don't for get swirl flaps. The care will be much faster and there are tunes that keep OBD Readiness all ready for people like me who have county emission. While you are at it, change all the vacuum line, $8 vacuum pump gasket and CCV breather hose. If you are changing valve cover gasket, might as well clean out the CBU and install new glow plugs/module, then you'll be good for another 100k plus in terms of engine.

much appreciated, i also read something about a vibration....pulley or something along those lines. I'm building my list to make this thing bullet proof. thanks again

Thanks for the reply! I'll look into all of it. Luckily i'm tooled out and I have access to a two post lift. I'm sure I'll be back for questions as I tear into it.

For me it was out of necessity...but I would have preferred the BRR as I've heard nothing but great things about it. I got the 200 mi countdown and for the first 150 miles of it I did everything I could to remedy it with no luck. Contacted BRR via text but when I told him what state I live in that was basically the end of the conversation, lol, never heard back and didn't want to pester. The customer service at TME, and of course the countdown, is what ultimately sold me on the JR tune. Honestly at the time I didn't look at it as a "tune" per se, but more as a cost prevention measure for the future of failing emission components and CBU...

BRR doesn’t tune anymore. SPD has rights to his tune now. The problem with JR is the amount of people with the higher performance tunes that have issues

There are three types of 335d owners:

Group 1) stock
Group 2) tune for performance
Group 3) tune for reliability and to avoid costly future repairs

@Jgoody is Group 3 and probably not interested in hybrid turbo upgrades.

That’s great but Jr even has “reliable” tunes with issues. The hybrids just have the issues sooner

Nope, but if you go on the facebook group you will see multiple examples of it.

Fuck facebook™ You want alot of fuel? Figure out how to run it.

Or melt the tops off the pistons, your call.

My JR car runs mid-13's with traction control on street tires. For several years now...

What are you talking about? Fuel is limited by what you have for a fuel pump. Aka: r70, r90, or if you’re running dual pumps. You can’t get anymore from it then what it can put out. You can get up to 4-5mph in the 1/4 mile with dual fuel pump over r70 with stock turbos. Not sure what you’re talking about melting the top off the piston lol never seen that.

And mid 13s in a 335d? That’s slow af. Must have a sutphin trans tune too. My x5d is faster than that.
