• 784 Answers SOURCE: sounds like the high pressure pump is at fault,, or it could be a bad valve,, you can buy a rebuild kit for the pump and bebuild it your self -- but for just a few dollars more it is sometimes best to take it to a repair shop and have them give the whole unit a good once over just in case there could be something else that might need attention,, ( in the long run this is not a bad idea as this will ensure a longer/trouble free life of the unit ). The turn around time for this service at a repair shop is about 2 to 3 days and the cost of the pump repair and service will be between 85 to 125 dollars ( depending on where you live and what the shops hourly rate is ). 1993 Mercedes Benz 300e Owners Manual download free.
