Hi,

The tyre pressure warning light has turned on in my Mercedes c220d 2018.

I pumped to 36psi, most were 34-35 but the lights aren’t turning off.

Any ideas?

Have you reset the TPMS?

No, I was concerned that if I do that then I could be hiding a genuine problem.

How do I know the correct psi for each tyre?

Have you pushed OK on the steering wheel?

If it were a problem wouldn't the warning light come back on again? We had a similar thing a couple of years ago when the same warning light was coming on, each time for the same tyre. Kept pumping it up, reset it, a week or so later it would come back on again. The tyre was quite new, appeared to be fine, but did turn out it had a slow puncture o_O

Reset won’t conceal a problem. If there is a fault it will alarm again.

Yep - pumping up the tyres won't reset the warning. You have to do it manually.
