I was changing the oil in my 2011 135 JB4 and found the exact same leak pattern. For the first time I had to add a quart between the last change and this one, and figured the consumption rate was...

Out of curiosity, have you had the vanos recall service performed by a dealer? I believe this recall is independent of warranty. That could be a fix for those codes, but either way you should have...

I have one of the first N55s, bought Jan 2011, I think I'm up to about $30,000 in repairs at 93,000 miles. I stopped counting after $15K.

Most of it was covered under warranty or recall work. ...

A little 135i N55 troubleshooting help?

I've been running JB4 since Stage 1 on my 2011 135i E88 N55. I have 91K miles on the car and installed Stage 1 at 5K miles, so it's been running strong for a long time. My current setup is JB4 with...

N55 MAF connection

New firmware says you may clip off the purple MAF intercept for cleanliness, or leave it dangling. The install photos show a red X over the factory MAF sensor connection. What is the proper...

Get an FMIC with stock-style clips. For realistic expectations, remember that FMIC's don't add any hp, they lose less when it's hot.

My VRSF 7" was a downgrade due to much worse throttle response. In addition to the added FMIC volume, it's possible there was a leak somewhere since the silicon couplers are very difficult to...

Just put a $1000 water pump in my 135i convertible at 70,000 miles. My mechanic was mildly impressed it lasted so long.

Two months ago I put a $70 water pump in my 10 year old Nissan truck at...

I tried both options above. The BMS is a much nicer solution. The AFE box does not fit, it overlaps by an inch in the back so it doesn't seal or even try to seal. The AFE's cone is small, with...

They have to deem it "normal wear and tear" after they take it apart and examine it - which they did. If they call it worn from abuse, then it isn't covered. I was sweating that one, needless to...

I installed a JB4 in my 2011 135i E88 at 5K miles (Map 2 then Map 5 ISO and now Map 3 ISO/Meth). I had over $15K in unrelated warranty work done (not counting new VANOS bolts that took 2 weeks),...

I'm running a 2011 N55 JB4 with meth, an FMIC, and no dp. Meth provided a good solid boost, especially with NOS MMT additive or 3 gallons of E85, either of which get me to 18+ psi.
