Keeping smoke out with the windows open?
 

Now that the nice weather is here, I was running with windows open (not warm enough in the Northeast for A/C yet), tried sunroof open, windows closed.....all open.There didn't seem to be a "combo" that wasn't letting in the diesel smell. (Oh, and with all windows/sun roof closed, there is zero smell)

Anyone have a "trick" or know of a combo that works better than others?

FWIW, when I had leaky injector return lines last summer, I initially thought it was an exhaust leak. We went up & down the whole system with a mechanics stethoscope listening for a leak.....and didn't find any, so I don't think it's that. Once the cracked injector return lines were replaced, all was well. This condition was real bad with all the windows up/sunroof closed.

I also double checked that the tail pipe exit was NOT (somewhat) impeded by the rear bumper (which might cause gases to perhaps find their way into the trunk area), so I don't believe that's the culprit either.

Anyone have any suggestions? Is there a setting on the ACC that gives the cabin (more) positive pressure and keep the fumes out?

Thanks in advance....

Any rust holes underneath? There is a grommet for the speedo cable, is it in correctly?

Tail pipes that exit straight out the back can sometimes get fumes into the car. Pipes that bend down at the back as they exit the bumper are less likely to be the cause of exhaust entering the car via a window or other aperture.

My (long gone) Golf diesel with a straight exhaust exit had exhaust coming in via the driver window while the other (long gone) Golf D with a downward tailpipe did not.

You could try an inexpensive exhaust tip to see if that makes a difference.

I know

It's an old Diesel. It's gonna have a smell to the exhaust. If it is really bad, maybe your engine is not burning the fuel efficiently. I am currently investigating this possibility with my car. The exhaust smells fuel-rich and I get white smoke at idle.

I have not found a way to keep the exhaust from entering the cabin with the windows down. It is not really an issue for me since I rarely smell it. If you sit in traffic a lot, I can see it being a problem. In that case, roll up the windows until you are moving at a steady pace.

Pretty much. I would 100x over smell an old Diesel than some DEF hopped up stink box! That DEF crap burns my nose and lungs and I'm a smoker for crap sake!

not a joke..if you can run some biodiesel the smell is much more pleasant. B20 and above you cant smell the petro.

Check for an exhaust leak again. Except at a stop you shouldn't be getting any exhaust smell inside the car.

x2 on an exhaust leak, just because it was sound a year ago is no proof its sound now.

Also, if the exhaust ends in front of the edge of the bumper it will swirl around and get in the cabin.

Thanks guys. Southern car I brought up w/o any rot holes underneath. This is at 30-40 MPH. I kinda eyeballed the turn down exhaust and the rear bumper doesn't seem to be in the path of exiting exhaust????

I can try some biodiesel, as I love donuts.....

I've never had this issue with a straight or curved exhaust execept when I had a leak up front, I suspect there's a leak in your system somewhere.

Incomplete combustion of fuel, either by wrong set timing or low engine compression or both; you will ultimately find to be your problem causing the excessive diesel fuel smell inside of your car. When timing of fuel injection to engine compression is properly set, there is miniscule diesel smell, period.

grab the exhaust downpipe where it exits the turbo... inspect the flex connector... I'm betting it's cracked. look for signs of carbon

Everything I own are OLD Diesels, I never get smoke in the cabin area. windows up or down. X 2+ on a leak some where in your exhaust system.
