new overland crd - strong burning smell.

So our new overland diesel suddenly produced a fairly strong burning smell at about 300 miles on the odo, and half a tank of diesel yet to go. Just tootling around the suburbs.

When I parked I could see small amount of smoke lit by the headlight drifting out from under the hood so I think the climate control was pulling it in.
Opened the hood, there wasn't any obvious smoke, the smell was dissipating. No warnings or high temp readings.
Came back an hour later to go home - no smoke smell now.

No oil drops on the driveway that I can see.

DPF regen? I wasn't aware a regen would produce smells at the front of the car.
new engine burning off factory coatings? why suddenly like that.. this was the first day I had set climate control from cool, to heat though.

Could it be an oil leak onto the manifold? Should I wait till it happens again before taking it in. Is there anywhere I should be looking with a mirror or something.

and there I was thinking, well, all the gadgets and so on appear to be working well, perhaps I'll not have to visit the dealer much.

thanks.

You may be referring to the new car small that occurs when the catalytic converter is burning off the coating on the metal. This is normal, but mine didn't last past 50 miles, and was mostly noticeable outside the car. Otherwise, you may be correct about some oil on the exhaust manifold. This will burn off shortly if that is what happened.

Re: new overland crd - strong burning smell.

It was very sudden, like we had to roll the windows down.. I know new cars have all kinds of interesting smells, but this was like someone burning electrical and rubber almost in the cabin.

If it was oil on the manifold, I'm obviously wondering if a seal has let go.
Although today no smells were reported. I guess next time I'll stop and open the hood with the engine still running to see if any smoke is coming from the back or front of the engine bay.

Re: new overland crd - strong burning smell.

It's always possible something got kicked up into a hot place on the car and burned off, like a plastic bag.

Re: new overland crd - strong burning smell.

I noticed the same issue with mine. I picked it up exactly 30 days ago, and I was getting a strong odor as well. I chalked it up to new car smells, burning off paint on catalytic converter... I drove it for 3 weeks and would get intermittent burning smell. And then last week, I noticed a few drops of oil on my garage floor. Grrrr.

Last weekend I took it on a road trip of about 1000 miles.... Yesterday morning I saw quite a bit of oil drops on the floor, crawled underneath last night and it is definitely leaking from somewhere. I think its transmission fluid, but it's not red. Might be power steering fluid? I don't believe its engine oil. Oil level is full on dipstick, I can't check transmission fluid level, and I didn't check power steering fluid level. Steering is fine, shifting seems fine...

It is at the dealer now, dropped it off this morning. I will let you know what I find, but based on my experience if you smell something burning it is not normal. I'll report back what they find. Hopefully something minor, but I'll let you know.

Re: new overland crd - strong burning smell.

Just heard from the dealer... transmission is leaking from the hydraulic pump inside the bell housing. It's not a huge amount, he topped off the transmission with about 6oz. It's not a huge amount obviously, I've driven 2500 miles in 30 days, and only recently seeing any amount of oil. My hopes are that the leak has been small and will remain small until I get back to the shop.

Warranty is going to replace the whole transmission, I'm sure it's cheaper and easier to do it that way than to tear it apart and try to replace or fix the pump.

They are going to order the transmission which takes 5-6 days for shipping, and they can swap it out in a day, or day & half worst case. I can drive it until they get the transmission in, and I'm scheduling the work for next week.

FYI if you interrupt a regeneration cycle on your DPF in the future it might give the same smell. There isn't any kind of indicator that it's happening, but it happens every couple of days based on your driving pattern.
