As a follow-up to a post several months ago, I have a Check Engine light on my '95 E320 wagon that is making me crazy (and poor). The following has now taken place and I would greatly appreciate some advice from those who have been kind enough to offer such in the past.
- CE light was diagnosed by dealer as bad air mass meter which they replaced;
- light came back on and was diagnosed as bad O2 sensor which they replaced;
- light came back on and I was directed by several folks on this group to try replacing the fuel filler cap before wasting any further money;
- I changed the filler cap and the light has now come back on.
I have now gotten the fault code from the diagnostics box (26 flashes) but don't know what that means. I am afraid to take it back to the same dealer who has now apprently misdiagnosed the problem two times (nearly $1,200 to their favor).
Your advice is greatly.
Thanks in advance from a very distraught Mercedes owner in Texas.
