Does my ds5 have direct or indirect tpms?

[Henrique14]

Hello. Hoping someone can help.

My tyre pressure fault light has been on the last few days, it flashes orange for 30 seconds or so then stays constant orange on the dash.

I have no idea if I'm on a direct or indirect tpms? My car doesn't measure the pressure of each wheel individually, instead I just get measurements of 'ok' across all 4 tyres if it's ok, but obviously right now I'm getting a 'tyre pressure monitoring error'

My local Kwik fit sorted my wife's car the other day as she had a fault direct tpms sensor, I asked them about mine but they said if it's indirect they cannot sort it.

If my car doesn't measure the exact psi of each tyres individually does that mean it's an indirect unit my car is using?

It's a 2015 ds5 reg yb15 uju

Thanks

Post up the VIN (it will auto hide) and we can check.

If it is indirect, are all the tyres the same make and, crucially, are they all the same size?

No, even the Direct TPMS system does not always measure the individual pressures. Earlier systems like on the MK I and II C5s did, but the MK III didn't - it only told you the specific tyre that was punctured or deflated.

Indirect systems may or may not advise of the specific tyre that has pressure loss, but often these just tell you there is a pressure loss problem, and you'll have to check which tyre it is.

So it really depends on the system fitted. If you are getting the tyre pressure warning concerning pressure loss or a puncture, I'd say the system is working, but if it's a TPMS general fault without a tyre pressure deflation specific warning, then there may be a problem with the system. Once we have the VIN, we can determine which type you have.

Thanks.

Still confusing as this vehicle has the TPMS wheel transmitters fitted but no TPMS Receiver (ECU) listed, and is the EU Standard 64.02 system. That is has the '02' amendments to regulation 64 tells should indicate that this TPMS system is extended to spare wheels / tyre and run flats. So that would indicate to me that it likely to be the indirect system.

Sorry was that in relation to me?

Have also attached pic of my valve which I believe someone said can tell if it's that system via that?

Hi, yes, my reply was in answer your your query.

What does the Vin number show? It's meant to have a direct system?

Also, how would I get this fixed as I rang my local Kwik fit and they told me if it's an indirect system they can't fit new sensors due to how the sensors are located in the wheel hub? So I'm guessing it's a Citroen dealership to sort?

If this is the indirect TPMS system it is possible that it uses the ABS equipment to monitor the wheel speeds. As I understand it (and I could be wrong) the indirect TPMS system monitors the wheel speeds at all times (rather than just when the vehicle is braking, which is what the ABS does). If it detects a wheel is turning at a faster rate than the others (and the vehicle is not turning according to the steering angle sensors) it would indicate that a wheel has a reduced air pressure compared to the other wheels (as it would have a slightly reduced diameter, due to the lower air pressure).

The system I describe was fitted (as an optional extra I chose) to a Skoda Octavia I had as a company car. There was an extra button on the instrument panel, to re-calibrate the TPMS system when the tyres had been inflated or changed. When I had a warning I checked the tyre pressures, and found one was lower than the other three. I re-inflated all of the tyres and reset the system. A day or so later the system alerted me again, and it was the same tyre. It turned out I had picked up a nail in that tyre (fortunately it was possible for the tyre centre to patch the hole).

What did this button look like please? I cannot see one at all and can't find anything in my settings on dash to reset the system?

My manual states if there is an operating fault with the system to tske it to a Citroen dealership, it does not mention anything in manual about resetting the system.

On my Skoda (remember this was NOT a PSA vehicle) it looked a bit like a wheel (but this was over ten years ago, so I cannot be certain). What I would be inclined to do is to check the tyre pressures are correct, that they are of the correct size, and that they are of the same make (although it may be possible to have one make of tyre on one axle and a different make on the other axle without causing an error state). Anything that causes an error state (such as, for example, a Dunlop tyre on the front left and a Pirelli tyre on the front right) might be a cause for your problem.

Have you actually checked the tyre pressures? It may be that the system is actually doing its' job properly, and letting you know of an issue with a tyre.

I will check these, but according to my manual a flashing orange light followed by a solid orange light indicates a fault with the actual system, as opposed to an issue with the tyre pressures themselves.

I'm still struggling to work out if my system is a direct or indirect one

[Hell Razor5543]

The fifth post down this thread (which is from GiveMeABreak) suggests that you have the indirect system. The direct system will have a form of sensor fitted to each of the standard road wheels (some are built into the valves, others are stuck on the wheel rim (and enclosed by the tyre). Marc has found that your system can manage spare and run-flat wheels, so almost certainly does not have a sensor on each wheel.

The reason I asked about tyres pressures is that it might be possible the system 'thinks' it is at fault, as it has 'told' you of a problem that has not been rectified within a given number of cycles. It might then assume that you HAVE checked the tyres and found nothing wrong with them (and so the problem lies within the system itself) when in fact you have yet to do so.
