I've just read that a German car specialist in Singapore has managed to do this in an A4 B9. Anyone seen this offered in the UK yet?
Proper TPMS for B9

That’s awesome, I’d love that. Imagine you just need the receivers in the wheels and then maybe some recoding using OBDeleven?

I just called HazzyDayz on the off chance and he reckons they might be able to sort this, I'll keep you posted
I'm betting it will be eye wateringly expensive!!

Try our site sponsor @DJAlix to see if this can be done
Ah ok thanks Sandra - I thought he just did coding. This needs hardware as well.
RS4 has this so cant be too bad to retro fit/code...can it???
For me, this would be a nice to have but just another thing for me to become obsessed over and check constantly.,. Then I’d have to keep checking pressures manually to reassure myself the system is working & accurate lol.

Is that the RS4 display coded on an A/S4?!

On the left of terminator x's post it says the rs4 group, plus rs4 is displayed in the rev counter and only one person has suggested that could be coded...

Ha ha no sorry it's a RS4. DJAlix might be able to sort something though.

Unfortunately I can’t see any of that on my mobile phone, hence the question.

I got far more excited about that than I should’ve... Haha

Yes I have been caught out in the same way before now. Now I've stopped using tapatalk...
interesting I saw a video of an RS3 on Facebook too that happen to have it displayed at the time he was hooning it
surely if we have a sensor that detects a drop in pressure, the pressure must be monitored ??otherwise why do we reset it when we check pressures?
gotta be a little bit of fancy coding surely

I think our cars have indirect TPMS which uses the ABS system to detect a difference in wheel speeds. It's really only useful if you've got a flat tyre.
Yup, this.
I know you can buy the sensors that go in the wheels but if our cars don’t have the receiver then it’s a wasted exercise I guess...

On the car (B9 avant) I have ordered it says "direct". Perhaps they've changed it for MY18?

Awesome - so you guys may have direct TPMS (along with all the remote locking stuff from the app that the earlier cars don't) - very jealous!
The optional one on the RS4 is called ‘tyre pressure monitoring display’ which I think is still different than the direct tyre pressure monitoring which I’d assume is ‘directly’ from the ABS sensors?

Reply from HazzyDayz. What a good company - I've used them before for a SatNav install in my previous car and thought they were excellent.
Hi,
I've ordered a kit for R&D purposes in my own vehicle and will add this to our website and drop you an email once available.
This will most likely be early July.

That’s really cool then!
I wonder if there’s a separate receiver that needs installed or if it’s already built into the car...

The RS4 has TPMS, doesn't use ABS sensors. The "tyre pressure monitoring display" allows you to view the pressures on the screen, rather than it just bonging when a tyre looses pressure.
Yeah, I know the way they work, I just presumed that the ABS version would be an ‘indirect’ method and the one that used the sensors a ‘direct’ method. Just the typical random terminology being used by Audi...

Yeah, there's a small unit inside the wheel that monitors everything and sends back the signal. I just don't know if our cars will actually be able to receive them or not...
Interesting, mine is MY18, built in Jan, picked up last Sat in Jan, and mine does (see screenshot upthread).

You need to have a receiver unit in the car to get proper pressure measurement (direct) from any direct sensors in the wheels .. This receiver costs about $4 for an OEM to buy , and is basically a 433MHz receiver unit (TPMS units in the wheel transmit @ 433MHz ) and CAN interface. TPMS unit on the wheel measures pressure directly and also temp.. transmits it about once a minute to the receiver unit (To preserve battery life).
If you want to retrofit something, you can now by Bluetooth low energy TMPS sensors , though they connect to your phone and not MMI displays. So you can check real measurement on an app...
I was pretty pixxed off that on a £54K MY18 S4 it only has indirect TMPS... pretty poor from AUDI. My last 3 Bmw all had direct TPMS.

It is a joke, Audi should do what they do with everything else make it a option you can add.
Seems to be a bit of confusion on this thread and some posts have answered bits of the question but not fully so maybe I can add a bit of info to clarify.
Firstly (currently) the RS4 and RS5 do not have tyre pressure monitoring as standard. This is a cost option. The RS models have the same basic system that all models in the range have as standard.
European law dictates that all new cars must have a function to determine pressure loss in the tyres. The cheapest way to implement this (and what we all get as standard) is the ABS system detecting a change in the rolling radius of the wheel/tyre. This is why you need to reset it. You’re basically telling the system that the current rolling radius is the starting point and it will tell you if this significantly reduces.
The more expensive way of doing this is with special valves (one in each wheel) which measure the pressure and communicate this wirelessly to a receiver module. This then shows you the actual pressure of each tyre. Many manufacturers offer this as standard on their cars now but Audi as usual are gouging us by charging for it.
In order to retrofit it, you’d need to have compatible valves fitted to each wheel, ensure that the receiver module is already in the car, or can be fitted and then have it coded to work. The valves themselves are generally around £100-£200 a set and the. You’ve got the labour charges of getting a tyre shop to fit them. Then you have the receiver module (if it’s not already a standard part of the cars hardware - most likely it isn’t) and the labour involved in installing it. Coding will probably be fairly simple with VCDS or similar.
Seems like a fair bit of hassle and expense just to see the exact PSI reading on your tyres (unless your getting new tyres fitted anyway of course but even then...)
Personally, I’ve had it on my last two cars. It’s handy but I don’t miss it.

@Derboy
Thanks for the explanation but is it easier for those of us who have 'direct tire pressure monitoring system' installed on our My18 cars? Other than taking Audi's word for it, is there any way to independently check that we have direct TPMS rather than the indirect TPMS installed?

If your valve stems are silver you have direct (active) TPMS, if black then you have indirect (passive) TPMS.
If you had direct TPMS then you would have a menu in the MMI which would allow you to see your pressures and temps. If you don’t have this then you have indirect TPMS, which when selected via the MMI will only give you the option to “store current tire pressures”.
