Carbon Dioxide Fumes

[PLBMW]

I have a 2001 325i with 45,500 miles on it. I love it! I had been experiencing a high pitched squeal when driving periodically, but this morning I had no squeal. I did have this C02 smell as I drove 15 miles on a stretch of road that requires 35-40 mph. Once I hit the interstate and 65-75 mph, it ceased. It seemed to help a little when I turned off the heat. I'm pretty certain it was C02 because I now have a headache. Has a belt broken and allowing the C02 in the car? Help!

co2 has no smell. gives you sour taste in your mouth and is non toxic.

co has no smell, gives you headache rarely, and can kill you.

Then I guess I'm smelling gas fumes.
(And no, I wasn't following an old car or truck. I've been asked that several times today.)

We just did a compression test with the rag in the tailpipes and one person said they heard a leak. I've got a service appointment tomorrow. Thanks for your help.

if it is exhaust:

notoriously difficult to trace. ask for a co (carbon monoxide) monitoring device you can have inside the car. if the dealer has none, i heard that the regular one you can buy for home use (home depot etc) can work.

if gasoline smell: they will find the leak, but i know of no weak spots in e46 that do this.
