Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here. If in fact your dealer diagnostic are correct then they are correct and you would need to replace the complete tank assembly. There are no parts sold separate .
There no way to know which is bad with out checking power and ground to them and Mercedes do not sell them separate . They are sold with the tank assembly. One option you may have it locating one from a salvage unit.
