Tial BOV

JacobT · 03-22-2014, 05:31 PM

Spent two hours to install ER CP today. What a pain, German engineering, everything is so tight in the engine room. I ended up removed the cowl, the PS reservoir and bracket in order to put the CP in place.

Went out for a test drive, everything worked out well. The Tial BOV is so quite, I can only hear a little "woosh" at around 5-6k rpm, otherwise, it's so quite. I'm happy with this upgrade

I just installed a new ER charge pipe with Tial bov today on my 2007 335i and it stays about 1/4 open at idel. If this is a spring issue,is there a diy to get in there and either change it or shim it? Should I try some silicone spray on the o-ring or some oil or something? Could it just be sticking? Thanks

Depending on what spring you have you can either buy some washers to shim it or get the next spring up.
