My "Check Engine" light has been on. WTF!??! I guess we can't expect a quality product for $3.85/gallon.

You can listen to the story here: http://www.wbz1030.com/

 

I have had my check engine lite on also. Open your gas tank top, and put it back on, close the door, and it usually turns off the lite, after one or two starts of the engine!

 

Thanks for the tip, but did you listen to the story? Something's wrong with the gas. It's effecting Mercs, Audis, VWs and of course, Xfires.

 

Are they adding too much Ethanol?? All the stations here have notices on the gas saying there is "Less than 10% Ethanol"

 

I guess they don't know yet - and they don't know what we should do. 1290 degrees in the converter! 3.85/gallon for petro-urine that can cause catalytic converters to melt. I'm bullsh!t.

 

I really doubt that it is because of the ethanol...ethanol has less BTUs in it than regular gasoline, so it would not be responsible for hotter than normal cat temps. Sounds more like the possibility of some diesel fuel contaminating the gasoline........Just a thought.

 

Thanks for the insight. I know nothing about the makeup of fuels so I'm completely in the dark. I had about 1/2 a tank tonight - the Check Engine light was on - so I filled it to the top at a Citgo in NH. It was just a stab in the dark because there's no information on which brands are problematic. The light was still on. On the way back from work I stopped at a Mobil and topped it off (about a gallon). Started her up - no CE light. I don't know if it was the Mobil or the Citgo that ultimately did the trick.

The highest gas prices in history - and this is what we get. Fill er up and keep your fingers crossed that the junk won't wreck your engine. I wonder if there's talk of a class-action lawsuit. I'm sure there's an attorney out there who's not happy that his pricey Benz, Audi, etc. is subject to damage due to the negligence of gas suppliers. Count me in.

I am the person in the interview with WBZ radio! There is a very big potential problem here with cat temps getting really hot!!!! If you can confirm for me that you have any of the following codes in your MB relating to O2 aging time exceeded, above or below threshold value exceeded, or short to signal wire then you must have the tech look at the O2 in actual value. You will find that if you have the contaminate in the fuel your front O2's will be very lazy with values .450mv plus or minus about .075 and rear O2's fixed around .047mv. If this is the case have your tech look at the act temps at idle. If the temps are getting up to the 800 degree f my advice is not to drive the car as I have stated in the news report. There is a potential for fire if this advice is not heeded. WBZ is investigating the situation and would seem that the source at this time is the fuel depot here in Boston. Im really serious about the issue as we do not know as of this writing what the contaminate is yet. I feel confident it is not not ethanol as that test takes only a few minutes to perform and monday I'll test my two samples and let every one know. Stay tuned this is a very serious problem. Audi has been replacing multiple sets of cats and O2 sensors trying to mitigate the problem B4 they and benz got together and determined it is neither mechanical nor electrical. Numerous samples of fuel were tested and found to contain the contaminant!!!!
Stay Tuned

Keep up the fight. I will be watching this closely. I buy my gas in upper NH. when possible as they don't use the ethanol there yet.

 

I'll bet it's that damned Toluene!

 

Same thing happened to our Escalade EXT. Engine light came on. We think it's something to do with the ethanol.

 

Thought I was in the clear, but on the drive home from work the CE light came on again. I'll go back to the Mobil station I went to yesterday and add to the tank. It worked once, maybe it will again. This is bullsh!t.

Thanks for the info! Bastards.

 

I use 10% ethanol more often than I prefer, but never had a problem. I'd still vote that your gas cap is not seating properly. That will throw a code. There was another post in one of the other forums that the owner cleaned the rubber well and lubed it with WD40, and that stopped the problem.

While it may appear that the different gas cured the problem, it could also be that you seated your gas cap properly after filling up.

Or I could be full of crap.

 

Nope. Not the cap. It's running very roughly and lost power on the highway. Going to the stealership tomorrow. I've put some dri-gas in there, in case water in the tank caused the problem. All this stuff started right after I heard that story on the radio about the bad gas.

Apparently it's effecting high-end cars with Planar O2 sensors.

Has anyone here with a CEL gotten the codes run to see what they indicate the problem is ??

 

Not yet. I don't have the thingy to do it, and the way it's running, I'm not taking it to Autozone or anywhere else except the stealership. They can't look at it till tomorrow morning I'll post when I find out more.

 

I had TEN fault codes - consistent with the bad gas issue. Two O2 sensors replaced. $800. Not covered under 7/70 warranty.

Here's what Marblehead, MA mechanic Bob Ansell relplied to my query over on Benzworld.

 

Did they give you a list of the codes?? I would be interested in seeing the complete list.
