Not happy with the ripoff by BMW on the VANOS Solenoid, I went ahead locate some resources to manufacture some.
My car used to have a small issue with VANOS in Bank 2 as shown in this screen shot:
I installed two solenoids provided by a vendor that reputably specializes in designing and manufacturing automotive parts. I only replaced the two solenoids in Bank 2. Test results look pretty good.
and
Here are a few more pictures for the samples
I installed the two samples on my beast dated back on Aug 27 and they have been operating without any issue since then for over 1200 miles.
I've started manufacturing a small batch. With all the costs taken into account, the selling price should NOT be more than $120 for each solenoid. Not sure if anyone is interested here?

Those solenoids will fail a vanos test and give a value of under 0.59. I tried this out about a year ago with one vendor I was led on to and I believe they still sell them based on when I shortly worked with them. In short, they are no better than you cleaning your currently solenoids and putting new o-rings in.
I have a batch of 2500 solenoids from the OEM supplier to BMW which are due in around Christmas time. They give a reading of 0.88 or better which is of new condition based on being installed in a used engine.
Not trying to crap on your thread, but you should share the vanos test result for bank 2 which will read as both being "not ok".

You probably did not read the numbers from the screen shots that captured the test results before you replied. The quality readings for two solenoids are 0.8 and 0.7, which I think is reasonably good. Other readings are all within respective ranges.
I am also enclosing two more screen shots that indicated more test results as being 'OK'.
The CURRENT readings from the testing is 218mA and 265mA for the two solenoids. They are the only 'NOT OK' as they deviated from -150 to 150 set point range.
As I said, this pair of valves have been functioning normal on my beast for more than 3 months and 1200+ miles. I feel reasonably confident with them from both initial test results and real world driving experience.

Also...slightly off topic...do the original OEM Vanos solenoids have a black body and aftermarket have a silver body? Just curious, I've seen a few Vanos DIY on here and it appears that original equipment Vanos solenoids may have been black. All (4) of mine are silver. Just wondering if those were replaced at some point by previous owner...I know the engine was replaced in 2011 with a new BMW engine, maybe it would have came with new solenoids?
So is this $120 for a new solenoid? Or reman or what? I'm going to play sceptical here till something awesome happens then ill be all up on Sophie.
I changed my o rings recently and I brought all 4 of mine from no good to about .60-.72 which I was pleased with. It got rid of crappy starting and warm idle fluctuating.
$120 is for a brand new solenoid. No refurbish, no reman. As I said, I have two of these solenoids running on my beast for 3+ months and everything is awesome thus far.

Good observation. Very originally, I believe these solenoids start with black body, but the latest OEM solenoids have a silver body, so do my aftermarket ones.
Hello all S85 owners,
Can this engine rev to 10,000RPM
bore: 95mm
stroke: 75.2mm
very "over-square" design: at 1.26 bore vs. stroke
Is it accessories? Alternator, P.S. pump, etc.?
Transmission?
Electronics?
This bore/stroke design is for HIGH RPM.
Love 8,250, but can we get more?
Mr. P
Hello M5 board, Mr. P asking if anyone knows reason for bore issues on the S85?
Recently purchased for a rebuild and Cyl#8 and Cyl#10 are terrible.
Also noticed an e-bay seller trying to sell block/crank with similar issues, so this must be an issue.
pics attache, want to know root cause.
Mr. P
So I recently succumbed to the dreaded throttle actuator issue. I researched on a lot of the forums. I looked at the various options for a solution. In the end I sent the actuators off to BBA Reman. They organised the collection of both actuators and I had them back within a week, with I have...
Hey guys,
searched around and i have yet to come across any actual info about how much worse MPG gets after going catless.
i’m currently getting 10-12mpg on the highway and 6-9mpg in city, So im hoping MPG might improve a bit after replacing my front set of o2 sensors and running some CRC...
