I had my oil/filter change, & the FSS Plus computer reset. When I got the car back, it said service D due in 10,000 miles, service items 4,9, 12, 14. The requirement to replace the plugs and the fuel filter at 32K miles had magically disappeared without the work being done. One can only wonder how many thousands of $$$ are being spent each day by MB customers on unnecessary service just because "the computer says so."
Very interesting that the plugs and fuel filter service "disappeared". That's actually what I would want to happen too. I'll be making an appt. for my SErv. F and hopefully I have a dealer that has the knowledge, and co-operation akin to yours. Will keep everyone posted. Tpowel2: sorry about the bill, but at least she's good for 5 yrs. and if u get a plugs/fuel filter due before that, show 'em your receipt. BTW, I'm not sure which Contis u used, but I went to Tirerack, and punched in '04E320, and I got a number of OEM Contis with the highest price being $137 each.....

So is the FSS calling for these 100,000 mile or 5 year service items because our 2003 cars are now 5 years old? I doubt it, because my FSS was calling for new spark plugs and fuel filter in November of 2006, when my car was only 3 years old.
So why would the FSS be asking for this work to be done if the manual specifically states 100,000 miles or 5 years? is it because the computer is telling it that there's something wrong with the spark plugs or fuel delivery system?
I have 50,000 miles on my car, and I do my own work, so changing the spark plugs and fuel filter doesn't bother me - I just don't want to do it if it isn't really nescessary...
