Hello Buzzie,
What about the fuel pump relay you had replaced?
I forgot to mention that the 3rd brake light is different from the 300e in that its longer because of the slope of the rear window. I have replaced mine and they should be able to get these from the dealer. What happens with the rear brake light[3rd] is, it sits in the sun and the plastic becomes extremley brittle, and you have to be very careful removing the back portion to replace the bulb. Your MB repair shop should have known this. They probrably had the the young lad do this?
My CA 300ce has 250K miles on it now and it just passed the Ca smog again.
Like you I love the car and so does my wife who drives it every day to work, 80 miles a day. Its hard to believe that these cars when new sold for 56K. I have the original invoice and we are the 2nd owner. The manufactures estimated Hwy gas consumption is 22 mpg. The only major repair we have had is the transmission went out. Its never been to the shop, I have fixed everything, except the tranny.
However, it comes at a price these cars are old now, and the fuel system may have been state of the art at that time, but as the computer and its associated components age, wierd problems start to arise. Some of these were recognised early on by Mercedes. So, when you take to the shop for repair some of these older guys who new the car arent there anymore.
Good luck
