Thanks for the help in advance-
I have an 07 335 and my oil catch can contributed in breaking my very brittle
pressure converter/ Turbo boost solenoid.

I want to replace them both while im doing the job, where can i purchase these? Other than the dealer which is my last resort. "also from my search tischer used to have them for 91 a piece but i cant find them"

Also i used to do alot of work on e36 bmw's and they have a similar EMISSIONS VACUUM ELECTRONIC VALVE EGR. would this work as a temporary replacement since i have a few laying around? "but i would prefer to keep it oem"

huh what?

[axi005]

My pressure converter/ turbo boost solenoid broke. Im looking for a replacement, I called the dealer they quoted 210 per solenoid. Are there any online sites that sell them?

and the e36 sensor looked similar with the e90 sensor, i was wondering if they could be swapped since its just a vacuum sensor.

check tischer or find it at realoem and than ebay the part number.

If you're talking about the 2 pressure converter valves that mount on the passenger side of the valve cover, your e36 parts won't work. Get a set of 2 updated valves from someone like tischer.

Fwiw, most of the valves I test on older 335i models leak. Even if you aren't experiencing any symptoms, it's a good idea to test them. Both of mine were leaking at 24k miles -- one badly. There is a reason BMW has revised this part several times.

Newest part number! Just replaced both of mine.

Boost solenoids they have upgraded these ? where have I been ? haven't heard anything about this ..have an very early model 08 never replaced mine but then again never had any boost issues either .

[Bme30]

The original part # from my 07 was superseded twice. I had one go bad so I figured might as well do both.

Yep..... the new style also look physically different, so it's easy to identify the changes. The older style are prone to leaking. I think anyone with an earlier car should at least test theirs to see if they hold vacuum as they should on the intake side.

[axi005]

Sorry for the delayed response, I appreciate your guys quick responses and information. Love this forum

I initially noticed low boost symptoms and then it gradually got worse, i check all the vacuum lines and finally noticed the little tube portion was cracked which i think was caused by the placement of my oil catch can.

Once again thanks for the help!

what OCC do you have? post pics?

[BillionPa]

210 per solenoid??? damn, mine is like, $130 each

[Sparky68]

I guess this is related and could not see the point of starting a new thread.

Suspect my pressure converter/solenoids are leaking or not holding vac. Pulled the lines off of the vacuum tank, 1 tank i got a whoosh as the air was sucked in the 2nd one nothing. I assume this means one is screwed?

[BillionPa]

generally yes, the part has been superceded a couple of times, so it may be worth the labor to replace both at the same time, and the vacuum lines too

[Sparky68]

Found these online, im guessing unbranded parts but same part number.

[Sparky68]

How difficult are these to fit?

[BillionPa]

Pierburg is an OEM supplier for BMW, I have bought several BMW parts with Pierburg logos on them.

I do not think installing these should be difficult at all

Just thinking if I should take off my OCC - can you tell us more on how the occ contributed to the boost solenoids going bad?

details on testing procedure? Anything else I should check while I'm in there?
