My 2009 C350 has the TPMS light on, and I am wondering how to turn it off. Does it need to be fix with the dealer? or we can do it by ourselves? Thanks

It's on because one of your wheels is either low on pressure or one of the sensors has finally died. The only way to shut the light off is by replacing the sensor. If you replace the sensor you should replace all four at the same time.

If you replace just one sensor the remaining 3 will fail consecutively and you will just waste time and money getting each wheel remounted and rebalanced.

That mean I only need to buy four sensors and go to replace them in a local auto shop. I don't need to go with dealer,right?

That's correct. The TPMS on the W204 does not need any programming to be recognized by the vehicle. You simply install them then drive, after a few mins/miles the car learns each sensor on it's own.

Thanks for your help. It is really good to know that I don't need to deal with the dealer. Bty, do you know where can get 4 TPMS sensors with affordable price?

And just to add my $0.10 because I don't know where you are - as far as I know, USA C-series cars have TPS inside the tires and Canadian cars don't - they monitor wheel revs via the ABS system and don't monitor actual pressures.

They way to tell - if you car has metal valve stems it's a TPS. If it has a rubber stem, it doesn't.

did you check to make sure the tire is not low on air

I bought from these guys http://www.ebay.com/usr/tpmssale

Agreed... Replacing all 4 TPMS sensors plus having to pay for removing old sensors and installing new sensors would be an expensive fix for just having low air in one tire.

Much cheaper to get 1 @ $36.95 or 4 @ $36.95 X 4 = $147.80 from this Amazon Seller:
