Just like those who change the fuel filter for no good reason other than the fact that they want to spend money.
If you want to look after your engine change the oil and filter at around 3,000 miles not 7,000 or whatever the readout says.
The relays in the RCM are a problem so they should be looked at once in a while. Changing the Cam Position Sensor is a waste of money too.
Keep spare CPSs and a spare RCM in the trunk along with the tools to change them. Carrying a code reader is a good idea as well. Buy quality parts, Bosch is best.
Buy Bosch or walk home.
A fuel filter is not expensive you can get the OEM for $40 or even less. I have had the crankshaft position sensor go out and it was at the worst time so I do change it every 4 years or so because it was an awful experience. Only change the cam sensor if you get a check engine light for it and I did many years ago.
I agree buy Bosch for any parts it made specifically for the Crossfire/Mercedes. However Bosch brake pads are the loudest and the worst! Stay away.
