engine light

[jayjayw87ulh]

Hi, any help would be greatly appreciated.

My car is a 2001 CLK 230 kompressor.

About 3 months ago the engine light came on but I kept driving the car until one day I noticed a loss of power, I restarted the car and the problem went away but I felt we should get it checked out so I took it to a garage that has the star / merc diagnostics machine, they gave me a report (attached) and mentioned the o2 sensor and the gearbox conductor plate would likely need changing. They didn't have time to change the parts as it was just before Christmas so they only did the machine diagnosis. I mentioned to them that the O2 sensors had already been changed (as I initially felt this may be the issue) but they mentioned one may have been provided faulty, they said they did not know which one was faulty but when I told them (after a google search) the fault code on the report refers to the front sensor they said "oh well that's the one then". We then changed the front 02 sensor again (bosh brand) but after about 10 miles of driving the engine light came on again today. As you can imagine, due to their uncertainty I wanted to get another opinion. Does anyone think from the attached report that the gearbox conductor plate is the likely issue or could this be something else. The car currently starts and drives fine but the engine light is still on.

Thanks in advance for any assistance and best wishes for the new year to everyone.


Just to to reiterate, this was diagnosed with a merc diagnostics / star machine

Any chance of a picture of the warning light. Also, what is the mileage?
Thanks

Those are all historical codes - nothing current. Have you had a flat battery recently? It's pretty common to see fault code lists like those as a result of a dead battery.

Erm is that a serious question. the EML is the same on all mercs and has been thr same for last million years.

EML can me triggered by many many things and car needs codes read by a COMPETENT mechanic to correcly diagnose.

Many thanks for your reply.
I've not had a flat battery, but it was left for a month without use but it started first time without any issues...when the light came on I took the battery out to check if it needs charging but its was only 25-30% lower than full capacity, I charged it fully but as you know the light came back on.

Yes an EML light. same as pretty much every car on the plant - about 1 billion.

you should also seek a new mechanic. if i was at a mechanic like yours with those responses i would walk.

where are you based. perhaps someone can suggest a garage near you.
