C220 CDI Fuel Gauge Glitch Update

[kevinororke]

Hi,

Thought I'd just report back on this problem which I posted a few weeks ago. The problem was that if I filled the tank with diesel the gauge went to full and then dropped to empty over about 10 mins. When I had used up some of the tank (10 - 20%) the gauge suddenly started working again. As long as I never completely filled the tank there was no problem. I was going to take it to an independent to get it fixed. However, further research has proved that the problem only occurs if I brim the tank up to the filler end. If I only "fill" the tank then there is no problem. I think I can live with this and still have not got a clue what is causing this very peculiar problem.

Regards, Kevin

Thanks for the update Kevin,
Just for the record the gauge on my C280 has the same tendency, but not as dramatic as yours sounds. I live with it too, because after getting home and switching off, everything goes back to normal when I get the car out next morning. The car is 12 years old so I expect the odd quirk.

It will be the sender. They are notorious on the 202 but as you say, hardly worth fixing.
