My parents recently purchased a 1997 E420 with 230,000 miles. The body
is in perfect shape, the interior is clean and the car drives smooth and
strong but there are a couple problems:
1. The headlights (halogen) are dull, faded and yellowed. I tried
plastic polish on them using a buffer and they're about 50% better, but
ideally they should be replaced. Can the plastic lens part be purchased
or does the whole assembly get replaced? I'd prefer the European E-Code
headlights if they need to be replaced.
2. The climate control doesn't work. The display works and indicates
that things are working, but no interior fan. Not sure if the compressor
is kicking on or not. Is this a common problem?
3. The cruise control stalk is broken, well, limp is more like it. Does
not function at all. Common? Expensive to replace?
4. The warning triangle (ASR) light never illuminates in the
speedometer. Not when starting the car, nor does the ASR button turn it
on. Would this be a fuse/relay issue or could it just be a bulb burnt
Also, what weight oil is recommended? I tried looking in the manual and
it refers me to the dealership. Based on the service records everything
from 20w-50 to 10w-30 was used in the car (California's Bay Area.) Is
I'm familiar with European cars... VWs and Audis in particular so none
of the stuff wrong with the MB seems too major :)
