Hi Guys,

I have the following code in my computer:

Diagnostic Trouble Code (DTC) P0450
DTC Definition: EVAP Emission Control System Pres Sensor Fault

I took it to my local indy mercedes shop and they said it was the right fuel level sensor. Does this sensor also sense how much pressure is in the gas tank? I thought it only senesed how much gas is in the tank for the fuel gauge. Please let me know what you think.

Oh, by the way, the shop said that the pressure in my tank was at 58mbr and that is bad or something (or maybe it was -58mbr).

Thanks!

Yep.. thats sounds about right.. I have seen a W202 with an evap code.. did testing to find out it was the fuel sending unit that has a pressure sensor built into it.

Is it ok to drive with this sensor not working? The local mercedes dealer says they are booked until 11/29 due to some sort of recall w/ the E and SL class.

shouldnt be a problem.. as long as you can handle the check engine light on.. stuff like that!!
yeh.. the SBC update on the W211 and R230's.

Thanks for the answer! I really appreciate it. I was worried I'd be without a car for 9 days

I bet all the dealers must be really busy with that SBC update.
