2000 C280 hard idle and check engine light - PeachParts Mercedes-Benz Forum

Hello I have a 2000 C280 with about 77,000 miles. Today at the stop light the check engine light came on and then the car started to idle very hard. I am guessing this is a MAF sensor? I hear thats common on the W202. Any help would be great.

Sooo....is a C280 sport a reliable and inexpensive vehicle to own?

It seems like its always having a problem!

I'd pull the code to find out what the problem is, that should send you in the right direction. Even a place like autozone should be able to read it.

What does "hard" idle mean? Rough? Pull DTC's and report back.

I have been dissapointed with it since the day I got it actually. I have had no major issues but just lots of stupid little things that can drive you crazy. Its just not the car I thought it was.

. It just feels cheap especially the interior. God it awfull.

. I am guessing this issue is a MAF sensor. I hope I am right.

Yes it is a rough idle. The car shakes while stopped.

Maybe one of the coils went out or a spark plug is fouled?

It sounds more like bad spark plug wires to me. Have the codes checked, don't guess!

No I will not guess. Not with any of my cars. I will get her scanned tomorrow and keep everyone updated.

i have seen a few C280's or other W202 chassis do this when the ov relay is bad or has blown fuse, not 100%, just my $0.02

If i remeber, its too new to have a over voltage protection relay. In place has a k40.

I see you are sporting two addresses, NY & Fl. Does this vehicle set while you are away?
Or did this start when you entered Fl? If you answer YES to both questions, I am sorry to tell you this but your car is suffering from "ERI". "ERI" is not fatal, but has been known to require a complete physical. The doctor usually has to enter through the back side with some alterations being made up front. Recovery time varies, mainly due to the size of the wallet.

"ERI" is spreading across the country at an alarming rate, caution to all gas vehicles.

Feel free to PM me for additional details.

The car is with me here in NY. I found the issue a couple days ago. The codes where that it needed 2 new spark plugs. Everything is ok now. Thank you.
