Hi guys:

i am new here!

i have a 2002 c230 coupe.

on the display. there's a light sensor visit workshop!

can anyone tell me what to do?

anyone has this problem before?

and also. today i drove the car and the ESP came on too. and after i shut down the car and turned it on again it went away!

everytime i start the car. the display becomes really dark and the i have to turn the key like few secs to start it!

the car is auto. but sometimes when i drive it on the freeway. it doesn't shift itself. the rpm was really high. like 4-5 when i was driving 50 miles or so! any idea on what's wrong with it?


my car is out of warranty now. do i buy extened warranty or do you guys have any suggestions?

Thanks for the help. i really appreciate!!!!

Thanks for the help!!!!

One of your bulbs is burned out.
Check ALL of them ( headlights, high & low beams, turnsignals, brakelights, licenseplate lights, foglights, etc. ).
When you find & replace the defective bulb, the warninglight on the dash will go out.

I had that on my 2002 C240 it wasn't a bulb but a sensor for the headlights as I recall, I need to chk the dealership work order, which I can do tomorrow.

But I would chk to make sure no bulbs are burnt out first like advised above.
I think your car actually tells you which bulb is burnt out on the dash display when it is a bad bulb.

Thanks for the help.

i think it was light sensor . visit workshop on the display!

thanks man.

i checked the bulbs i didn't find anything wrong with them. i will go back and check them again.

play around with this site to get diagrams for your car http://www.detali.ru/cat/oem_mb0.asp?TP=1

and I'll chk my work order for the part#


also a W203 site is www.mbklasse.com
I don't think it will have details for your problem but it may

That is usually a indicator that the light sensor may have failed.
It is clipped to the windshield just in front of your rear-view mirror.
Behind the plastic cover.
Was you windshield replaced recently? Glass guys can be hard on them.

Think the dealer is expensive? Do you know how much it costs to train a dealer tech? Or buy the required MB special tools to have on hand?

Thanks DR D

it is amazing how the Mercedes diagnostic computers at the dealership clue the technician in on what the problems are - may not pinpoint at once but gives clues on where issues are.

How old is the battery in your car? if your running the original battery and the battery is old and not up to the task it can cause all kinds of issues including transmission function -I've experienced it myself.

On my 1998 C-class my `bulb out` dash light came on telling me my headlight bulb went out, kind of coincidental after replying to this thread a few houre earlier.

The C-class coupes are really nice cars and do lots of cool things and when one little sensor or car battery charge drops it causes lots of little errors.

my battery is the original battery. it's been like almost 5 years.

so maybe that was the problem?

what kind of battery should i buy? how much is it? where can i buy it from? is there anything i need to know when i change the battery?
i read somewhere says when change the battery. you have to follow the steps or the ESP or whatever will come on after you change ?

where can i find out how tos?

Again. Thank you very much for the help!!!!

call mercedes roadside assistance, 1-800-for-mercedes,

they come out and change your battery - jump start or chk it - just tell then your problem when you call- that the electrical system in your car is acting weird and you need a new battery - and they just charge you for the battery.

If you were to buy anything other then a Mercedes battery you wouldn't get the free jump start or roadside assistance diagnostic.

Figure around $125 for a new Mercedes Battery (think they are from a Spanish company Varta) WORTH IT!

A five year old battery in a C-class realy should be changed out for a new one, that would be the first thing I do.

even if i am out of warranty?

sorry if the question is stupid! i haven never use the roadside assistance before!

so total would be $125 or something like this?


thanks a lot

even if out of warranty - the facts should be in your owners manual- pretty wild!

Battery could be anywhere from $117 to about $140, you can call your local dealer for a price. If you live where it get cold and you use the rest feature then I'd only buy a Mercedes battery.

Mercedes really does have a very cool thing going, Their roadside assistance is great, run out of gas or need a flat tire changed and your within workable distance they'll take care of you.

Thanks

i live like 1 mile away from a dealer
