Dear community, I have W245 200 CDI (EU)

The Runflat system, seems to be working, correct me, but it's working via ABS sensors, not the pressure sensors in the Rim.

I tried to flat one tyre today to 1 Bar , others were on 2.5 approx, and I didn't receive any warning.

A bit odd.

Any suggestions?
Br,

The warning light should come on when you drive the car because the flat tyre will rotate faster than the others.

Hello, Yes I am aware of that, I drove 50 km/h. I had a leaking tyre 2 years ago, and the indicatons were working without a problem.

I connected it to Autocom diag, under Instrument section, I found TPMS , and it is: no errors

Mine often shows a reset required when changing tires and rims from winter to summer driving. The air pressure is very sensitive to fluctuations in any variance in the tire pressure..

There is a notice/dash warning when driving at any medium highway speed if the tires are out of equal pressure. There is also a "reset" requested and that is easily performed by the steerring wheel buttons. Well explained in the in car book manual if I remember correctly. If you don't do the reset..the messages will add up and show in the dash.

I am aware of the reset, thank you , it just seems that the car doesn't mind of empty tyre's anymore :/

You should always see a warning or message..will have to be looked into then.
