Driving with one TPMS sensor
Hi Benz lovers. My car is equipped with only one TPMS sensor on one tire. The other three tires don't have TPMS sensors on them. The TPSM flashes and stays on every time I start the car. What does this mean? Do I get readings from only one tire that the TPMS sensor is on? If I am to get TPSM sensors should I buy only 3 nos. or buy 4 Nos.
Thanks.
Thanks.

I would buy 3 and have the shop program the 3 to work with the existing one plus your car.
Why the 3 did not have any? Someone removed them or the rims were changed?
I had to replace one due to broken stem and it cost me $72.00 installed and program at Discount Tire.

I bought the car like that. I guess they were taken off.

You can just make it a point to check your tire pressures once per month and not really need to add the sensors. The sensors were added because most people don't check their tire pressures. Typically, the sensors don't send you an alert until the tires are almost flat which is not where you want to be running you tire pressures on a regular basis. This can cause your tires to wear out prematurely and replacing tires faster adds to the cost of ownership. This is an important safety issue. Relying solely on the sensors isn't the best idea because they can also malfunction. I have tire pressure sensors on my daily driver and I still check my tire pressures every month.

The TPMS on my 2013 W204 notifies at 4 PSI below the set pressure, well before the tires are flat. I don't know about the 2008 pre-facelift models. But from experience, getting that message every time you start the engine or park the car is a bit of an aggravation. I can see why a person would want to get it fixed.
