Audi uses the same indirect TPMS as VW on most models — inflate to spec then press SET in the MMI or instrument cluster menu to relearn.
Why the Audi tyre pressure light is on
Audi's indirect TPMS compares wheel rotation via the ABS — it doesn't actually 'read' pressure. So after you've changed wheels (winter to summer), rotated tyres, or just topped them up, you MUST do the SET procedure or the system will think the new baseline is wrong.
Audi tyre pressure light reset — step by step
- Inflate all four tyres cold to the placard values (inside the fuel flap on most Audis).
- Switch ignition ON, engine off.
- On A3 8V/8Y, A4 B8/B9, A6 C7/C8, Q3, Q5, Q7 with MMI: Car → Servicing & Checks → Tyre Pressure Monitoring → Store Tyre Pressures (or 'Confirm').
- On older A3 8P, A4 B7 with the small DIS screen: use the CAR button → Servicing → Tyre Pressure → Store.
- Some 2014+ models also have a physical TPMS button on the centre console — press and hold until the buzzer sounds.
- Light should clear within 1–2 minutes. If you've just changed wheels, drive for 10 minutes for the relearn to complete fully.

If the light won't go off
Light back on within a week despite a clean SET? You've got a slow puncture or a leaking valve — Audi indirect TPMS will catch even small losses over time. If you've recently had new tyres fitted and the light won't clear, check the fitter actually balanced and torqued the wheels correctly (a wheel slightly out of true messes with the ABS reading).
What it costs
Free DIY reset. No sensors to fail on indirect models. The premium Audis with direct TPMS (RS models, some Q8s) use sensors at £55–£110 each fitted.
Bob's workshop tip
After winter wheel swaps, do the SET procedure on the driveway BEFORE you pull away — the system needs a clean baseline, not one taken halfway through your first journey.

What Bob keeps in the boot
A pump puts air back in, but it will not seal the hole. For a nail or a screw in the tread, the repair itself is the Emergency Puncture Repair Kit — £9.99 with free UK delivery: rubber rope plugs, reamer, T-handle tool and rubber solution, posted from the workshop in Birnam, Dunkeld. If you would rather not take a wheel off at the roadside, the quick-fix tyre repair spray is the no-tools option. Keeping the pressures right in the first place is covered in tyre pressures by registration and resetting the tyre pressure warning light, and the pump itself in Bob's electric tyre pump picks.
Be straight about what a plug is: a get-you-home repair for small punctures in the central three-quarters of the tread. Never plug sidewall or shoulder damage, drive gently afterwards, and have the tyre inspected or replaced by a tyre specialist as soon as you can.
