300TD -> E320 Quick Questions
 

I'm moving on up from my '81 300TD to a 1995 E320, which is wonderful.
A few little glitches:
Cruise Control worked at first but now not at all. Replace brake switch first?
Then what?
After refueling the other day my check engine light came on, almost immediately. The LED tells me fault code "5." What one is that? I've heard about sensitive fuel systems where if you don't put the gas cap on tight enough it trips the system.
That's it for now.
Thanks,
Shawn

The most common problem regarding the cruise control is the CC amplifier. Usually the circuit gets burned or corroded due to age.
