Question about EPA/emissions warranty and O2 sensor on 00 ML320

[skiier3_9]

Recently our 00 ML320 check engine light came on so we took it to Autozone to have the codes read. The computer said that there was a fault at both O2 sensors on bank 1 side (pre and post cat). The truck has 71k miles on it and after reading the 8 yr / 80K EPA warranty I'm wondering if the replacement of the O2 sensors should/will be covered by the warranty?

TIA

The covered 8/80k items are listed in the warranty manual. That list shouild include the catalyst/intake manifold/exhaust manifolds/ & fuel ECU. SENSORS aren't covered!

O2 sensors are on the list, i checked on my way to work this morning. I was just wondering if it will be covered even if our state doesn't do emissions testing. I don't know whether the bad sensors would cause it to fail emssions testing or anything like that. We have noticed a decrease in fuel economy lately.

If the O2 sensors have failed and are covered under warrentee.

Who cares what the state law is-MB should replace them. It is critical to replace them BEFORE they kill the PRECAT and CAT.

After reading the fine print it says that the sensors are good for 2 yr / 24k miles

I thought the Federal law was all emisson related parts 80k.


Have you tried talking to the service writer about this????
