I'm reposting my question since the thread I posted in got off track about whether the car can smell bacon or not. While amusing, I need a real answer
--- Original question below ---
My auto recirculation used to work fine. But after about 6 months, I started noticing the smell of diesel exhaust behind trucks or buses. My dealer replaced some sensor, but it didn't help. When I took it in and complained again, they ran some tests and claimed that the sensor is working fine. They stated that:
"The AUC sensor that controls the auto recirc function does not detect diesel exhaust. AUC sensor is operating properly at this time."
In other words, they say that I should expect to smell diesel fumes because the sensor isn't designed to specifically detect it. I find this hard to believe. Anyone out there have solid evidence that I can use to dispute their claim?

Same here, I never notice diesel, or other smells when the auto circ is on. I've been quite pleased with it's performance. Push the dealer harder......they're slacking!!

it could be the re-circ flap thats not closing properly... I would think they've checked that... but thought I'll throw that out to make sure.
