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
