I've been looking into new TPMS sensors. Spent quite a bit of time on this, the idea is to get fresh new ones, and I figured by now there might have been changes over the years-
So the various tpms sites offer options-RDE048V21 and RDE011 from Huf, which is now BH sens: http://www.products.intellisens.com/...4180D8ABDA6614
Tpms bargains sells them and also the RDE011, said to also work and about $30 cheaper
And then Tpms direct has them too, this one is a bit more confusing in their description but might be the RDE011, even though the picture is an orange one, and it says "item might differ from photo":
Tpms247.com seems to think a 2009 GT3 exists so I wouldn't bother-
Anyway, after searching reenlist for quite some time, some have used the RDE011 just fine instead of the RDE048V21. The RDE048V21 is also listed as just RDE048 which could mean it's an older version and the V21 is a newer generation(?) On the Audi R8 forums someone also asked the same questions trying to compare RDE048V21 and RDE011 but no one really seems to know-
Also, since the RDE048V21 is used on Aston Martin, Audi, VW, Porsche and a long list of other cars, it appears on eBay searches. But upon closer inspection, many eBay pirates say it's the RDE048V21 when you can see in the picture it's actually the RED011!!! So beware of eBay sellers-
I don't buy from Amazon and usually try to get from independent online stores(got some Mikuni parts from a Midwest store so they can continue to exist)
Just did the same thing buying tires-it takes a long search but it's worth it. Searched through the 997 Turbo, 997 and 997 GT2 GT3 forums
So now I'm deciding between the RDE048V21 and RDE011. From reading some threads, I see some have used the RDE011 with no issues, but there's no info to really compare them-
Just get fresh ones that fit. These Were about 100 for the set from tpms.com and we’re made about 6mo before i got em
german hur
these are for a 2013 carrera i think part for early 997.1 is different
you can call them on difference. I seem to recall one is a later version https://www.tpms.com/Porsche-911-Car...che-911991.htm
There's no doubt the RDE011 will work, I'd just like to know if the battery life or anything else is different than the RDE048(recently re-labeled as RDE048V21?) It's more or less a $34 price difference between the two models. I'll probably write one of the vendors asking for comparison details and specs-
Definitely good to examine manufacturing date upon delivery
As mentioned, many eBay vendors say they're selling the RDE048V21 when in fact, when you look at the pictures it's the RDE011. So I wouldn't buy there-
So I went to the source to find out manufacturing dates and to try to find the RDE011 on the BH Sens site: https://www.intellisens.com/downloads/
It looks like the the RDE048V21 is the current sensor as expected. The RDE011 is listed on the Porsche list, but it's a previous sensor. Buying it for $34 less does save quite a bit, and I read batteries are dormant anyway until installed-
Impossible to find out any differences between the two, but from reading the user experiences cheaper RDE011 works just fine. And it seems like the last factory cars with them were 2016 Boxters:
The pic you posted is of the RDE011, and as you mentioned, made in 2019. It could be that they still made them in 2020 too, then phased out. I'll write tpmsbargains and tpmsdirect and ask what manufacturing dates are stamped on theirs. If the batteries are dormant until activated anyway, the RDE011 should be fine and $34 cheaper than the superseding RDE048V21
no idea what difference is. they send temps and pressure to the dash lol. they are spot on to my digitial longacre meter when cold too... the set i replaced with these were identical except the had the "P" marking on them. at 7 years old, still working OK too...but with new tires going on decided it was time. sync'd up on tpms reset in seconds.. TPMS.com shipped fast too.
at some point i'll turn the system back on in my 997RS.
TPMS is useful, just not on a track car it's a PITA.
My original 2011 sensors haven't failed, and they predate the RDE011 ones which were superseded by the RDE048 model. So if the RDE011 has been manufactured until 2019 or 2020 I see no reason not to use them. I'll contact the supplier and enquire about manufacture date before purchasing.
I contacted tpmsdirect and they promptly confirmed these RDE011 sensors are manufactured in 2019, so I ordered and will post if there are any issues.
My conclusion is that since it appears BH sens acquired Huf, as per their own catalog, the new sensors are RDE048V21, and the RDE011 was superseded. But since these were manufactured in 2019 and batts are dormant until installed, they should last 9 years like my original ones have- https://www.tpmsdirect.com/Porsche_G...008-08-uvc.htm
Sensors came in and I’m happy to see they were made at the end of 2019👍
Tpmsdirect included instructions which were stapled to the plastic bag
Now I’m trying to decide if I install the valves myself and follow the torque specs or just let the tire installer do it-what’s this about a shear washer? 🤔
Oh, I see-that’s the torque for the valve nuts, after sensor is in the rim, before mounting the tire 😅
I assembled the stem to the sensor loosely, but will let installer do it-
But still, how many shops will use a torque wrench?
I was curious about this before I have tires mounted with new sensors(my car still has original functioning sensors)-But I'm always weary about tire shops and neglect/incompetence. Years ago an installer tried to "crack" the center lock nuts with the wheels on the ground and luckily I was there to stop him and insist on removing the nut with the car up in the air. That was the last time I went there, and always remove my wheels myself then take them to get new tires installed. I've also had to get wheels re-balanced before
The shop that last re-balanced my wheels seems pretty good, so I'll go back there. Will ask about the torque wrench and try to observe installation. I imagine some probably do it by "feel", don't think that should be acceptable-
Sorry for the late reply here but to answer several questions.
RDE048 and RDE011 are the exact same. You can also use UVS2000. They are all the same protocol. RDE048 will be identical to the OE sensor from the dealer except it will say RDE048 and not have the Porsche logo.
Do not get hung up on the manufacturer date as long as they are new. The second they are made they go into "sleep" mode and will not use the battery.
You can use "5%off" at TPMSBargains.com to get an additional 5% off. Ships quickly (well as good as USPS is right now) from Kentucky.
Yeah, I figured it all out and posted the BH Sens chart a few posts before, thanks
Will try to observe installation, including the use of a torque wrench
Also gonna degrease and clean rims myself before tires get mounted and balanced to ensure weights don't fly off
