OK thanks. Good to know.

Our 2010 two wheel drive and our 2016 4X4 passenger Sprinter both had and has pressure sensors

I'm guessing you are talking about the 2500 chassis in both cases? All newer Interstates are built on the 3500 chassis with duallies in the rear and sadly you can't order those with TPMs.

One would think that with all the options that Mercedes offers (and Airstream selects) there would be a TPMS system for the 3500 chassis. Though knowing how complicated MB makes things, maybe we don't want them involved. Low tire pressure due to a bad sensor would probably put us in some limp-home mode.

What's crazy (and frustrating) is I had the wacky idea of buying one of the in-wheel TPM sensors from MB, plugging it in, and seeing if the "smarts" in the van were already there and it would pick up the signal and just work. When I was doing my research, I found that MB DID offer TPM sensors for 3500 series Sprinters at one point, but then stopped. The reason I didn't try my experiment was because the sensors come in two flavors, each operating at a different frequency. So, unless I wanted to waste double the money, I wouldn't know if the sensor wasn't working because the TPM is disabled in the computer, or if it's the wrong frequency. The reason I wanted to try this was because I've been in the tech industry a long time, and I know that it's more expensive, and more complicated, for manufacturers to offer a zillion different configurations of a product, so often times they make one version of something and just disable certain bits of it (don't populate a chip location in a circuit board, set a register to ignore certain areas of memory, etc).

Long version of a short story, I totally agree with you and certainly they could offer this. Why they don't is a mystery that maybe someone on here has some insight into, because having a factory TPM system would be a huge safety benefit on these vehicles.

As has been posted before on this and the Sprinter-Source forum MB does not offer a TPMS on 3500 dually Sprinters because they are not required by US DOT. Perhaps if enough people contact MB and ask for TPMS as an option they might offer it.

That happened after I bought my 2001 Prius that did not offer cruise control. Lots of owners complained and Toyota offered it as an add-on kit since the software was already inside the Prius computer.

But they used to offer it (you can order replacement sensors direct from MB for certain MY Sprinter 3500's), so what's changed???

Couple comments.

I don't see many mentions of ensuring the inflation is sufficient to support the actual load. I have numerous posts on this topic with specific suggestions and even a few examples. I would consider your Sprinter to be just small Motorhomes so the inflation would be set with the same method and margin.

Yes Alignment is a good idea

Finally, if your unit didn't come with TPMS then a good investment would be an aftermarket system I have run / tested both internal and external sensors. I see no significant advantages or disadvantages to either.

Just be sure to calculate the total life costs of whatever you choose. Batteries or sensor replacement, cost to dismount tire so internal can be installed and possibly hose extenders on rear duals. Remember that some systems can be easily moved from one vehicle to another while others could cost $60 to $100 to move.

For me one significant hassle of external TPMS is where to put the display. As it is, all I can tolerate is my cell phone dangling in front of me.

I just had an alignment done and front wheel balance at North Trail RV Dealer in Ft MYERS, fl. They had a full service chases shop. Cost was 189.00 for alignment. I started to get a shimmering in steering wheel at 65mph. Problem is gone.

I put my TPMS module into the slot above the ash tray. Unless it's beeping at me for pressure violations, I only need to look at it first thing in the day, then when I stop for fuel, food, or end of day.

Thanks. That is a good option. Are they battery operated or do you need to hardwire them?
