I found this thread using the site search. I have exactly the same problem with a 1996 C200 petrol, auto, euro spec. At about 300 miles it runs out of gas. To refill the tank takes 52 litres, while the owners manual states that the tank is 62 litres. Therefore it is leaving 10 litres (a little over 2 gallons) in the tank. Once refilled it starts and drives well. The fuel gauge is AWOL, reading randomly. Occasionally there is a very slight miss or hesitation in the engine revs.
Having searched the 'net it sounds like maybe a fuel tank filter problem? or a fuel tank "balancing" problem.
Does anybody know for sure? I have EPC for part numbers if somebody could tell me what part(s) I need.
Thanks in advance for any help. Greetings from Ireland.
Eddie.
