I have a 2010 too so I’m assuming mine will be the older switch with the smaller thread. I’ll check it out this weekend and if that’s the case I’ll have 2 switches available for anyone who missed out on the first group buy.
@8Lug , do you still have the original FAL unit that came with the car? Many of us have had our full systems replaced under warranty at some point. Wild *** guess, but that might be the difference between cars whose FAL units have the smaller thread switch vs. larger.
Yes, everything is 100% original. Never had an issue with the unit and it still works fine. As I mentioned in a previous post, I only went through this whole exercise to have peace of mind from having a backup switch should mine ever fail, and then yesterday when I was detailing the car on the lift I decided to just proactively swap out the old switch for the new one. That's when I realized they had different thread sizes. I popped the old switch back in and it still works fine. I'm **** about my hobby cars so I do still want to locate a backup unit, but will just buy the part from Porsche if we can't figure out if any of the switches in the Suco catalog are direct replacements.
I'm still confused by Bovien's post about thread size and what Suco calls 1/8 and 1/4-there's a hardware store nearby(it was closed by 5 yesterday)and I'm gonna go measure the old switch's thread-since you put yours back in the unit it's no longer possible-bovine said an M12 nut fit on it(I copied and pasted his comments above, post #465
Anyway, the shipped switches are indeed 0140-45903-2-009, on the chart described as 1/4-so you'd think logically that the smaller thread one would be the 1/8 model on their catalog.
So there are others that will buy your switch-Scott40 said so on post #428, and I had some late comers after the order was placed and I said that unfortunately it was too late to join-I'm subscribed to this thread so I get instant email notifications when a new comment is posted. A lot of people haven't kept up with it. I directed members like Scott40 here from another recent post, so once it's determined how many members need the small thread switch, those with the large thread ones can sell theirs-
And 5 switches from Germany is still cheaper than 1 from a dealer 😂
There was a 7% FL tax added to the total order, and there was no shipping to me since I picked it up in person. Whoever orders a new batch would have to do what I did, send the others USPS to the group-I think they would certainly be irritated with a request to ship out individual ones.
More on my impression with the new switch:
Even when the brand new unit was installed back in 2016, it has never risen this fast, with almost instant Lift light coming on. It still took about 3-4 lifts for me to hear the swoosh sound when deactivating it, and I guess it's because the tank stores the air to aid in subsequent lifts-cdixon's description is probably a good read for more details, many pages above-
The BSPP pipe thread standard is confusing because the nominal size which is what you see listed is not the same as the actual size.
For example:
BSPP 1/4 size has an actual major thread diameter of .518" (you can see in my pics in an earlier post i confirmed this measurement with a micrometer)
BSPP 1/8 size has an actual major thread diameter of .382" (this is exactly what my switch measured, see pics in earlier post)
So what we need for for the earlier lifts is size BSPP 1/8. However, the Suco catalog only lists NPT 1/8, which is not only a tapered thread, it also has an actual major thread diameter of .405".
JB do you have a contact at Suco that could tell us if size BSPP 1/8 is attainable?
I went by the hardware store with my old switch-I was able to fit a 14mm nut on it, but it’s fit a bit loosely, though it could have been tightened down. When I removed the switch from the FAL, it was a very tight fit, and seems like locktite or equivalent was used on assembly. I put the new one in with no locktite, just the aluminum washer-
So the 14mm nut did work, but the 1.5 mm wasn’t perfect. If you look at Suco’s site, you’ll see it’s pretty much for aerospace industry, so what they make isn’t really for automotive use, though this Austrian built FAL is used in our cars.
I then went to an Advance Parts nearby, and in their nuts and bolts section I saw a testing template where you can test threads-there is no M14, but there was an M12 which is what Bovien said fit on his switch
M12 is probably not a perfect fit weather, but I’m deducing that the smaller thread sei h is close to 12mm metric-and I posted what he wrote, though it was a bit confusing.
let’s see if he answers the PM with his exact part number-
Contacting Eric at Suco in FL is not a problem, but he is not going to know details about the Switch thread, he's probably going to suggest mailing in the switch to make sure if the part number is not known-
Someone at the factory in Germany would be a better choice to contact, with the pictures you have-but I still think it's better to wait for Bovien if he answers the PM. And, of the people who bought the switches, there might be a few, even more than 5, who would need the smaller thread one-
So those with time to check this weekend if the switch they received is the correct one or not, it would help accelerate placing a new order for the small thread version-a new post can be created to sell the other switches, since not everyone is reading this one.
So to sum it up-it looks like Bovien got the switch with smaller thread, and he said he was able to screw on an M12 nut on it, and what's needed is the part number to place a new order, once it's determined how many switches will be needed-
*The M12 might not be a perfect fit, but in his post he said an M12 fit, so the part number of the switch he received is the one-
So 964 90 is a different function, not the 13 bar one(?)
What you need is the 13 Bar with smaller thread size, and we need to determine the exact size of that thread, and Suco part number-
Will search some more JB
im away so cant access records, but when dealer fixed, i could have sworn the service record showed replacement of more than one switch. w part numbers
will check wheni get back
I clarified that on post #464: 997 341 964 90 is for pump until 000 111 997 341 967 90 is for pump from 000 112
The "until pump 000 111" and "until pump 000 112" was missing from that test. Meaning, the switch with small threadsPorsche Part number 997 341 964 90 were for the first generation pump, and the one with bigger threads, number 997 341 967 90.
But the hard part is finding the suco part number for 997 341 964 90(first generation, small thread size ones)
Stile waiting for Bovien to reply, I believe he lives in Denmark-
Bovien has not answered the PM I sent-as confusing as his post was, it seems he received the pitch with smaller thread, because he said he was able to fit an M12 nut on it. I was able to fit the 14mm nut, and as mentioned it was not a perfect fit-so maybe it's Imperial, aerospace, and you'd think the one listed as 1/8 would be the one to order-
I would say at this point if Bovien does not answer, the best bet would be to contact Alexander Weiss at Suco in Germany. With the pictures side by side he could probably confirm with someone at the factory which is the correct part number-in the worst case scenario, an old switch could be sent to mach. Since 8lug's FAL is still working, maybe someone else with a failed small thread switch could send it in if needed. But maybe the pictures and the fact that an M12 nut fit it is enough to determine which one is it-
The danger in revealing it's for a Porsche part number is they could refuse to sell and say to order it from Porsche 🫤

I just ordered a spare switch with the smaller thread (997-341-964-90) from Porsche, so when it arrives I will be able to confirm exact thread size and if Suco still sells that exact part, other members can benefit from a group buy.
