Ok got my bosch sensors a day early,after the install and a few full throttle pulls no throttle cut or misfires whatsoever,I am really impressed with bosch.Here is something usefull,I am getting 8 coilnpacks and a fuel pump for 100$,a local salvage yard got a 2002 clk 500 ,looks like the exact same coilpacks as a crossfire,crank sensor connector exact same one better quality i took that already and after checking the crank sensor same part number as well,the fuel pump is a pierburg couldnt read the numbers but the car only has 44k ,car is totaled side impact.Does anyone know if its the same as the sl55 pump if so i hit the jackpot that pump will be in my crossfire friday.
