Hi everyone, my 240 is running well, the only problem is, over the last couple of weeks it has developed a strange odor in the cabin. It's annoying and embarrassing, and I can't drive with it! I'm pretty sure it's not coming from the seats, and it's not as potent when one is sitting in the back seats. I think it MIGHT be coming from the dash, but I'm not sure if it's the dash or soemthing under the dash? It smells like an old cheese sandwhich, it's GROSS. PLEASE help me!
