Greetings from ARGENTINA ! 4 years ago I bought an immaculate, like new 1990 Mercedes 190E 2.0 litre automatic, with only 15,000 kilometres [9320 miles] on it ! I paid a lot but then all cars in Argentine are crazily expensive. [Photos of my car are here : http://mercedes190e.carbonmade.com/ ]
In early 2011 the original fuel pump failed. Mileage on the car then was 38000 kilometres [23,600 miles]. The fuel pump was replaced by a local mechanic [there is no Merc mechanic where I live], but it wasn’t replaced with a mercedes original part evidently. In late 2011 that fuel pump failed and that too, along with fuel filter, was replaced this time with a Bosch pump, supposedly recommended for Mercedes Benz. This has been the only issue I have had with the car in 4 years.
But ever since the second fuel pump’s replacement, fuel consumption has gone way up. Before I always got 450 to 500 kilometers per tank of 50 litres [[280 to 310 miles per 13.2 gallons of gas / 23 miles per gallon on average].
Now my fuel consumption is such that I get only 300-350 kilometres per 50 litres of gas [ 190-220 miles per 13.2 gallons / 15 miles per gallon]. I have had the pump checked, apparently it’s installed properly. It’s been months now and I am at a loss to know what could be the cause, meanwhile I spend a lot of money on petrol [gas] which bothers me !
Any suggestions what may be the cause and / or solution ? My car now has 43,000 kilometres [26,700 miles] and still looks as good as it did in 1990 !
Thanks in advance to Click, Clack and the general community for taking the time to read and hopefully respond to my question.
