What 2003 Mercedes-Benz AMG C32 owners say
Fuel & propulsion system
I was driving my car and it suddenly turned off on me. I tried to start it again but it would crank but not turn on. I had a lil less than half a tank of gas but there was no gas being delivered to the engine. After inspecting the fuel sending unit I notised that the plastic around the wire connector pins was a bit melted and there was a small hole that went straight trough the sending unit cover. I replaced the sending unit but the melting still continues. It seems like the wire gets too hot and the plastic melts around the pins. Im afraid this can even cause a fire since all the fuel is just inches bellow it.
The fuel tank on my 2003 C32 leaked. The symptom was a strong gas odor inside the vehicle. Upon further inspection, there was fuel leaking from under the vehicle. I took it to the mechanic, and he diagnosed it as a leaking fuel tank. When he removed it, he showed it to me and I saw the part that was cracked, which was below the rear seat of the car. There appears to be a widely known malfunction with fuel tanks for Mercedes. This was a very stressful event, especially with fuel leaking outside the car and not knowing what could happen (fire risk, etc).
