    No TPMS module response on VCDS

    2013 Audi Q5 Hybrid, 45 K miles, VCDS 18.9.0

    I'm getting an intermittent TPMS fault on the instrument cluster (not a low-tire pressure message). When I try scanning the vehicle, I've discovered that neither of the tire pressure modules (64 or 4C) show up as active.

    So how can I diagnose the TPMS fault? Where is the TPMS fault coming from?

    Thanks!

    Post a complete Auto Scan please.

    The trend in newer vehicles has been toward indirect TPMS in 03-ABS, particularly now that the tech exists to detect simultaneous deflation of all four tires. If you do have direct TPMS, that would most commonly be at address 65 but possibly others I think. Either way, an Auto Scan will tell us.

    Here is an autoscan from yesterday while the TPMS error was being displayed on the instrument cluster:

    No sign of a TPMS related fault anywhere, but sometimes there isn't when the system is functioning as designed and just reporting low pressure. There's no sign of a separate physical or BCM-integrated virtual TPMS controller, nor any complaints from other modules that an expected TPMS controller is MIA.

    Based on a PL24 FI inquiry on your VIN, it was factory equippped with PR-7K6 "Tire pressure monitor system (wheel rev. dependant)", a.k.a. indirect TPMS. So, you have no TPMS controllers or sensors, it's all software in 03-ABS. So, I would expect no address 65 in your GVL or Auto Scan.

    So how can I diagnose the TPMS fault? Where is the TPMS fault coming from?
    Without something showing up in the scan, we're going to need to know exactly what you saw in the instrument cluster. In particular, what makes you say it wasn't a low pressure issue?

    In the center display between the gauges, the word “TPMS” appears at the top of the display with a red background. This is usually where major system fault messages appear, like “HYBRID”. An alarm sounds. This is different from the display for low tire pressure.

    And, I will confess that I forgot that this vehicle doesn’t use TPMS sensors in the wheels. So it goes.

    This is what the 2013 Audi Q5 Hybrid service manual says:

    System fault in Tyre Pressure Loss Indicator (TPLI+):

    If the warning lamp flashes for about 1 minute after switching on the ignition and then remains steadily lit, there is a system fault. TPMS also appears in the instrument cluster.

    System faults are stored in the event memory for the ABS/ESP control unit and indicated by the yellow TPLI+ lamp in the instrument cluster flashing for 1 minute after the ignition is switched on. The TPLI+ warning lamp cannot be switched off by pressing the button on the multimedia system operating unit - E380- . Proceed as follows if a fault is stored in the event memory:

    – Connect up the vehicle diagnosis, testing and information system - VAS 5051 B- and select Guided Fault Finding ⇒ Vehicle diagnostic tester.

    – Select the relevant program in Guided Functions.

    – Follow the instructions on the screen.

    What's described above are the fault symptoms I observed on the instrument cluster.

    So, since VCDS isn't seeing anything wrong in the ABS module, is it possible that VCDS isn't recognizing/decoding the TPMS fault in the ABS module?

    Right now, the TPMS fault has disappeared, but it has been reoccurring within a few days. I'm going to try resetting the tire pressures in the vehicle car menu tomorrow and see if the TPMS fault goes away. I'll report back if I see this fault again in the next week or so.

    Your scan shows the ABS properly recognized. When VCDS says "No fault code found" it means it. If there are any issues reading fault codes, it will add "... or fault codes not supported, or a communications error occurred" (not sure I have that text exactly verbatim, but it's close). In other words, when you see what you've got there currently, VCDS successfully queried the module for faults and the module responded, "Nope, I haven't got any."

    Check (and if appropriate, adjust) tire pressures first.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    Difficult to say, then. Sometimes faults in other systems/modules can effectively disable other systems. One example would be what your ECU is complaining about, the function restriction faults. Speaking of, I see no other faults in other modules that your ECU should be upset about. However, your ECU emissions Readiness state indicates fault codes have been cleared VERY recently:

    Code:
    Readiness: 1110 1101
    If you have been clearing faults in the ECU or in any other module, we may be missing part of the diagnostic picture here. There may be other faults you'd think are unrelated that can have an impact. Anything you'd like to share on this front?

    Just to add to what Uwe said, even if there was a fault that VCDS couldn't decode, it would still give the numeric fault ID and just label it Unknown. In this case, there is currently no fault, although someone may have cleared faults as stated above.
