Well, now another update on my exhaust fumes in the cabin problem. I never got to bring the car into service to explore this yet. Thought it fixed itself. Curious that another poster said the problem disappeared after a while. Mine did too, but then I noticed that it seemed to return recently. Then it went away again. Why?

I really think it now has to do with the outside temperature, and the car's climate settings. For most of this winter now, no smell. All perfect. Then, we had a day when the outside temperature went above 50'. I started the car. I forgot to turn "auto" off. I backed up out of my driveway. The exhaust smell was back! I drove off, the smell disappeared. What?

Is there a sensor in there somewhere that stops outside air from being drawn in (plus fumes) when the outside temp falls below 50'??? And if the outside temp is over 50' does this sensor allow outside cool air in to augment the air conditioning if needed????

But, even if this is the case, why is engine exhaust able to enter the cabin at all? I suspect the problem will be back in the spring, disappear in the summer (no more cool outside air), will be back in the fall, and will then disappear again in the winter.

Turning "auto" off, seems to help, but not completely.

Wonderful.

Well, here in the south (Texas) we have had all sorts of temperatures recently - mid teens to 80's. I have yet to smell exhaust fumes in the vehicle - and my climate control is set at Auto most frequently, but not always and back out of the driveway - so should pull in exhaust fumes as I back up. I do not keep my DS garaged - so maybe that's a contributing factor...

Persistent Fuel Smell

I've had the same fuel odor inside my Discovery Sport. Land Rover worked with my dealer to replace the 2015 model with a 2016 and it's still happening. It happens when the vehicle is first started and while standing still. In my opinion, this is a dangerous health and safety issue that Land Rover needs to fix.
I am pregnant and AGREE - this is dangerous and making me very nervous. My 2016 disco is at the service center now for the 2nd time trying to address this exact issue and they "can't find anything wrong" nor do they "smell the gas smell." Incredibly frustrating.

We are in the same situation – the problems with our Discovery Sport (strong smell of exhaust gases inside the cabin) started one week after having received the car, and a couple of days later a lot of smoke started to come from the hood... (the car had less than 250 miles). It took the service centre several weeks to have the issue repaired. They told us that they have replaced some parts with manufacturing defects, but refrained to tell which were and did not give any document at all. In spite of said replacements, we have experienced again the strong smell of exhaust gases inside the cabin (the car has now less than 600 miles). We agree with previous opinions that this is a very dangerous health and safety issue that Land Rover needs to address urgently.

NO GOOD! The service department should ALWAYS give you a service ticket that lists EVERY detail of what they did to your vehicle. If they did not provide you with one, I would call Land Rover USA...or UK immediately. Let them know what happened and demand a record of your service visit.
While you are at it, have them open a case on your behalf on this exhaust smell issue and they will communicate with the service department of your dealership until its solved.

Again, ours has seemed to resolve itself, but if it returns its going in to the dealership and LR USA is getting a call.

Call Land Rover USA..or UK. Tell them what's going on, tell them your experience with the dealership and that that have been unable to resolve it. They'll open a case and help get it fixed.

This is the best course of action for any LR owner that feels stonewalled by their dealership.

Gas fumes

I have a horrible exhaust/gas fume smell in my 2016 DS too when idling, but especially after parking and coming back to the car a few minutes later and starting up.

Going in for 20k service soon and fully expecting the typical corporate garbage line of , "could not replicate."

Hello all, I am new to this forum. I’ve posted my story on a new thread but I also feel is necessary to leave a message here.
I also own a Land Rover discovery sport which is approximately 10 months old. I’ve visited the main dealer approximately 10 times with various different problems. Squeaks coming from the rear of the vehicle, breaks sounded like a freight train when you first apply them in the morning, poor fuel consumption and also the dreaded burning smell.
It was only open to recently I realise the most serious problem is the burning smell. After travelling on a few long journeys my twin boys nearly 14 started to become travel sick. To cut a long story short I ended up purchasing a carbon monoxide meter. When the smell occurred I will turn on the meter to my horror I found out we did have in fact a carbon monoxide leak. I am aware that carbon monoxide is odourless. Carbon monoxide is a byproduct of fuel not combusting properly so it stands to reason they may be a carbon monoxide present when the smell is there. What was alarming is I was often getting a carbon monoxide reading when there was no smell present at all, it didn’t always coincide with the burning smell which is more worrying.
I made Land Rover aware of this issue after showing them a video which I’ve now uploaded to YouTube. Previously they didn’t acknowledge there was a problem but after seeing the video they did in fact say head office is aware of this issue. The part that connects to the catalytic converter apparently is deformed and allows emissions to escape entering the vehicle through the ventilation system. There was no lodger as to when this would occur as it was often random. I am now in the process of rejecting my vehicle as I am aware this problem is widespread across new and old Land Rover discovery sport models.
I purchased the carbon monoxide meter from Amazon, notice I said meter, not detector. I would advise you to do the same, it is better to be safe than sorry. Often the seller will allow you to return the meter as long as it’s in its original condition within 14 days.

I have experienced a similar problem and just had the catalytic converter replaced - more specifically the issue relates to the flange connecting to the turbo. This was cracked / misaligned and led to the occasional odour and fume problem. The temperature can be an issue I think depending upon how this affects the connection and/or performance of the engine in general. So far (and it's been less than 24 hours), so good but will obviously monitor! My dealer spotted the issue by noticing some soot deposits on the pipe near to the turbo.
Hope this helps.

what year is your car? I got similar issue and they could not find the problem. They got hydrocarbon meter and measure the air inside however no carbon detected in the car.

Dealer finally fixed the oil burning smell in cabin. Basically the engine air vent hose was loose and it oil condense drop on the hot engine and created the oil burning smell

You probably want to ask service advisor get into the car with you. I drove for 30 minutes and when I showed up at the dealer, I didn't turn off the engine and ask of their guy to get in the car and smell it. And, he confirmed the smell.

We’ve had the same burning smell coming from the driver’s side (engine) and a strong vinegar smell coming from the AC as soon as we switch it on. Sent in in twice to LR and they can’t seem to figure out what’s causing the smell. We have a 2016 LR Discovery Sport HSE Luxury and it’s been in the service center almost every month in the last 6 months.

Very concerning and somehow seems to be related to the CO issue that Ford Explorer has - which is build on the same engines platform.
This has been widely publicized.... Ford will probably have to do a recall....

AS for my car - no burning smell or gasoline odor BUT - under very specific circumstance I smell for a few seconds hot engine oil (it's a very characteristic odor... not like gasoline, not like exhaust fumes)
It only happens under the following conditions:
- Driving with the heat on....leaving the car for 5-10 min and restarting with the Heat on - only at that point the smell will occur for a 5 sec....

I just want to jump in here as well. I have a 2016 DS HSE I bought in November 2017 from the dealership. It was one of their service loaners. I get the exhaust smell as well. I notice it sometimes when I very first start it up -- or when the automatic engine stop re-engages -- and almost every time I drop my boat off: I'll back the boat in, turn the car off, unhook, and when I start the car back up, I smell oil/exhaust almost every time. I switch to recirculate and it clears, but it worries me. I'll go ahead and buy a CO meter as well and start taking notes. Thank you all for this thread!

hi 'no more crap' I have had the engine exhaust fumes leaking into my car after 2 separate repairs it has been really bad to the point that I had to leave the windows open ( I have a 1 year old in the car with me wherever I go), the second time I called out landrover assist as the garge couldn't get me in for weeks even tho I have a 1year old who is getting poisoned by their car!! The engineer told me that this is a known issue with Landrover and that the part they have that joins the Exhaust to the DPF does not align correctly so the clamp around it keeps working loose (sorry I'm not very technical). I have gone through the process of complaints with landrover - got nowhere - then went to my finance company who have told me that I NEED TO PROVE that the part is faulty or they will do nothing. did you get it in writing at all about the faulty part and who did you get to that admitted it. I have lost all faith in my car, it is a joke! I have had a new balance shaft- new engine - condensation in my rear fog lights which effected the electrics its just a shoddy excuse for a car!!! any help would be greatly appreciated!!!!!! I hate hate hate my car now!!
