1994 Mercedes-Benz C-Class Elegance 1.8 Liter


A nice ride with a major fuel transfer problem


Major problem with the C180 duel fuel tanks and fuel transfer between tanks. Have taken car to dealer twice for repairs and twice to private mechanic. However, the car still runs out of gas with about 25 liters in the "secondary tank". No one appears to be able to fix this problem. I have been stranded on the hi-way 6 times in the last 3 years.

General Comments:

It is a good solid car except for the fuel transfer problem. The C180 is a little underpowered, but once it gets up to speed it is a pleasure to drive. The A/C is excellent the the paint and body still look great.

Would you buy another car from this manufacturer? No

100% Agreed, my 1994 C180 Classic, having the same problem. After replaced new fuel tank in 2005, I was happy thinking that this problem never happened again, but suddenly in September 2008 the same problem happened again. Fuel flow not running smoothly due to under carriage fuel hose burst, even the parts replaced. None of the Mercedes mechanic around my state knows how to resolve this problem, but advised me replaced a new fuel tank. All possible methods to repair, changed fuel pump, drain out tank and servicing failed to resolved this problem. I love my car, but I cannot afford to spend Malaysian Ringgit 3,000 for another new fuel tank. My friend suggest me to operate the fuel tank and do some modification, as his mechanic already resolved the problem with his classic Alfa Romeo. I am looking forward to doing so.

I also got the same problem with fuel tank. Mine is W202 C220. The car shut off like running out of gas, but the gas remains about 1/2 tank. Googling for this, the only clue is about the pressure in tank. http://forums.mbworld.org/forums/e-class-w124/180686-ran-out-gas-twice-half-tank-left.html post#14.

But no info on how to fix it.

W202 Mercedes car, stopping with still a half tank of fuel. Fuel sender units is the problem. When the car is running, sender units are suppose to balance the fuel on both sides through siphon action. When this does not happen, one side of tank runs dry while the other side is full, and the car stops. Check for blockages at fuel return, or else change both sender units.
