it dose loose some power on up slops. but then my old one did to. my calculation is simple. the car has years of service ahead of it. i got it for 480€ and that is a VERY good price here. mostly you can find un tested, un registerd, rusted MB card for parts for around 800 - 1000€. here mercedes are good and expensive cars. some of the parts on my car clearly need changing like the belts and others may or may not. but i do not know how the car was treated befor me, so i whant to give it the full treatment and then sit and injoy the my ride. the whole thing incl' 1 new injector nozzel and gp for syl3, oils and filters, belts, coolent change, etc' will run me about 200-300€ + i got that new 700amp maintnence free battary, disel filter and new fuel lines yesterday for 118.40€. that put the car in a total valeu of 1200€. and for a car like that that the motor on it will run forever if i just replace some surraounding part IT IS WORTH IT! just the head ache of calling to get a ride when it stalles or the pain in the #¤& when it won't start in the morning is worth it. and those surounding parts are what cause this problems.
p.s. angel, in my 200D i just remove the cable from the box on the right side wing where the relay is. ground the negetive from the multimeter set it to 200 ohm and tuch each of the femeal connectors to check ressistance. if thay rae good then nothing else is needed but if not you then need to check only that one at the gp itself to see if it is in the wiring or the plug. whay take the bolt off? just tuch the end of the plug with the positive multimeter probe while connecting the negetive to the car chasis for groung. it sould be the same in the 240 no?
