Exhaust smell

How high is the CO reading from the alarm?

I you can smell the exhaust chances are you have an exhaust leak. The exhaust after DEF toes not have any oder.

Don't have a permanent one on the MH and I've yet to find the one we had in the fiver. I guess I will be getting a battery operated one today.

I agree with Dave. First thing I would check is for an exhaust leak between head and exhaust manifold, manifold itself, manifold to turbo, turbo to exhaust pipe and muffler.

All you are looking for are signs of BLACK.

If the exhaust doesn't have a smell then what is it I smell? It is definitely diesel exhaust, I owned enought to know that smell. The exhaust should not smell all the time not just when the DEF is applied. And it's not all the time.

It will only smell before def treatment not after, hence the ex leak is someplace before the def is injected.

If this is you 2013 Fleetwood 40x, it should have a built in one as standard equipment!

And it is not un-common for new equipment to have power train problems such as exhaust leaks. Trucking companies keep new rigs close to home for the first 6 months because of those new rig problems. We should also expect that with our coaches and chassis.

There is the propane gas detector, it doesn't say anything about CO detection. It has not gone off. I purchased a battery powered one today. I will test it when driving back home.

The funny part is this isn't constant. After about 15 minutes or so it goes away. And most of the drive time it's fine. The last trip we took we didn't have this problem at all. So the first trip of 5 hrs it happened and went away, the second trip no problem, this trip after about 1 hr it happened and we were ending our road trip at about at around 1 hr 15 minutes.

I looked into the engine compartment today with a flash light. No black spots at any connection I could see, and what I could grab seemed tight. I have a service call at Fleetwood in November, I'll have them look at it, but I'll be sure to keep the CO detector up front while driving.

Good idea to have a CO detector. However, diesel engines produce very little if any CO. From what I have read there are some weather conditions that can have them make some CO. Maybe the amount of CO produced by the engine won't be enough to set off the detector.

The DPF, not DEF, is what makes the exhaust not smell like typical diesel exhaust. It still has a smell do it, though it's not very strong unless the DPF is going through regen.

If you are smelling typical diesel exhaust smell then there's not really anything else that could cause this other than an exhaust leak prior to the DPF.

Hopefully Fleetwood will be able to locate the problem quickly!
