That's my car. It's been that way for about five months with no issues to report.

Hey bro, you have those 25mm breather filters on your Stock DVs? Like the one in the pictures some pages back? I just did this "cheap" bov mod and its pretty cool, but i was wondering if those filters muffle the sound or affect the flow of the "blow off"?

[DietTab]

Nope. Doesn't quiet it at all. There is no 'flow' to disrupt.

do you have to disconnect both dv's or can you just disconnect the the front one and leave the one in the rear attached to the factory charge pipe

I am curious about one thing.

I had a MINI R56 before my 135, and i installed a BOV onto it.

Since the vent to atmosphere, it took a little more time to build boost compared to the closed circuit, but it did work as it should, purely for audibility fun.

But when i sold the car and removed the bov, converted it all back to stock, the ECU jumped straight in SAFE MODE. It threw a code about some boost leak issue. I had to get the dealer to reset the ECU to fix it. Why it happened can be a few possibilities but i do not know the exact reason why it did that.

So, those that have installed this BOV onto a car designed for recirculating boost venting, upon demodding, did you encounter any issues?

I want to remove the hoses that are just sitting there after doing this mod.

Just wanted to note to not get the 7/8in chair end. Get the 25mm chair end. It fits perfectly.

Did this mod last night. Love the results.

Probably the best $2 mod ever.
